Answer (a): 1 only.

• S1 CORRECT — The AIIB (Asian Infrastructure Investment Bank, operational Jan 2016) has GROWN to 80+ MEMBER NATIONS (as of 2018-19, approved members exceeded 80 — it now has 100+ approved members) ✓.
• S2 WRONG — INDIA IS NOT the LARGEST shareholder in AIIB. CHINA IS THE LARGEST shareholder (~26% voting share). INDIA IS THE SECOND-LARGEST shareholder (~7.5% voting share). Classic largest-vs-second swap.
• S3 WRONG — AIIB HAS MEMBERS FROM OUTSIDE ASIA — both regional and non-regional members. Non-regional members include UK, Germany, France, Italy, Canada, Australia, etc. The 'no members from outside Asia' claim is factually wrong.

Answer (d): To aim at faster resolution of stressed assets of ₹50 crore or more which are under consortium lending. The INTER-CREDITOR AGREEMENT (ICA) was signed by INDIAN BANKS in JULY 2018 as part of the SASHAKT framework (recommended by the SUNIL MEHTA Committee). Under ICA, the lead bank's resolution plan for stressed assets of ₹50 CRORE OR MORE UNDER CONSORTIUM LENDING (multiple bank lending) is BINDING on all participating lenders if approved by 66% of lenders by value — enabling FASTER NPA RESOLUTION and overcoming the earlier problem where a single bank could block resolution.

• (a) Fiscal/CAD — unrelated to inter-creditor agreements.
• (b) Infrastructure projects — separate financing mechanism.
• (c) Independent regulator — ICA is a coordination mechanism, not a regulator.

Answer (a): Banks Board Bureau. The BANKS BOARD BUREAU (BBB) is an AUTONOMOUS BODY (set up April 2016 under P.J. Nayak Committee recommendation) that SELECTS and RECOMMENDS CHAIRMEN and WHOLE-TIME DIRECTORS of PUBLIC SECTOR BANKS (PSBs) and Financial Institutions. Its role is to depoliticise top-level PSB appointments and professionalise banking leadership. In 2022, BBB was replaced by the Financial Services Institutions Bureau (FSIB), but the 2019 answer remains BBB.

• (b) RBI — regulator, doesn't select PSB chairmen.
• (c) Union Finance Ministry — formally approves BBB recommendations but doesn't select.
• (d) Management of concerned bank — boards have role in lower appointments, not chairmen.

Answer (b): 2 and 3 only.

• S1 WRONG — PNGRB (Petroleum and Natural Gas Regulatory Board), established 2007 under the PNGRB Act 2006, is NOT the FIRST REGULATORY BOARD set up by the Government of India. Many regulators predate it — TRAI (1997), SEBI (1992), CCI (2003), IRDAI (1999), etc. Classic 'first' over-claim.
• S2 CORRECT — ONE OF PNGRB's KEY TASKS IS to ENSURE COMPETITIVE MARKETS FOR GAS (authorisation of pipelines, CGD networks, market-opening) ✓.
• S3 CORRECT — APPEALS against PNGRB's decisions GO BEFORE THE APPELLATE TRIBUNAL FOR ELECTRICITY (APTEL) — this is explicitly provided under the PNGRB Act, 2006 ✓ (APTEL's jurisdiction was extended to PNGRB matters).

Answer (d): Neither 1 nor 2.

• S1 WRONG — LTE (Long-Term Evolution) is the underlying 4G STANDARD (commonly marketed as 4G LTE), NOT 3G. VoLTE (Voice over LTE) is a VOICE SERVICE running over the 4G LTE data network — not 'advanced 3G'. The 3G labelling is factually wrong.
• S2 WRONG — LTE is PRIMARILY A DATA-ORIENTED TECHNOLOGY but not 'data-only' (voice can be carried via CSFB fallback or VoLTE). VoLTE is specifically the VOICE service over LTE — it is NOT 'voice-only'; it rides on the SAME 4G data network. The statement's binary 'data-only vs voice-only' framing is incorrect.

Answer (c): 3 only.

• S1 WRONG — The Maternity Benefit (Amendment) Act 2017 INCREASED maternity leave from 12 weeks to 26 WEEKS FOR THE FIRST TWO CHILDREN, not 'three months pre- + three months post'. Specific-number manipulation.
• S2 WRONG — The Act provides for CRECHE FACILITIES in establishments with 50+ employees and requires the mother to be PERMITTED FOUR VISITS A DAY (not 'minimum six'). Specific-number manipulation again.
• S3 CORRECT — From the 3RD CHILD ONWARDS, women get ONLY 12 WEEKS of paid leave (REDUCED entitlements) — as per Section 5(3) of the original Act, retained in the 2017 amendment ✓.

Answer (a): Maintenance of law and order. The WORLD BANK's EASE OF DOING BUSINESS (EoDB) INDEX has 10 SUB-INDICES (topics): Starting a Business; Dealing with Construction Permits; Getting Electricity; Registering Property; Getting Credit; Protecting Minority Investors; Paying Taxes; Trading Across Borders; Enforcing Contracts; Resolving Insolvency.

• (a) 'Maintenance of law and order' is NOT a sub-index — it's a broader governance concept.
• (b) Paying taxes ✓ — one of the 10 sub-indices.
• (c) Registering property ✓ — one of the 10 sub-indices.
• (d) Dealing with construction permits ✓ — one of the 10 sub-indices.

The question asks which is NOT a sub-index — answer (a).

Answer (c): The e-Waste (Management and Handling) Rules, 2011. EXTENDED PRODUCER RESPONSIBILITY (EPR) is the principle that PRODUCERS bear financial and/or physical responsibility for the TAKE-BACK, RECYCLING, and FINAL DISPOSAL of their products after end-of-life. In India, EPR was first formally introduced as a STATUTORY CONCEPT in the E-WASTE (MANAGEMENT AND HANDLING) RULES, 2011 (under Environment Protection Act 1986) — notified to compel electronics producers to set up collection/recycling channels. EPR has since been extended to Plastic Waste Rules 2016, Construction & Demolition Waste Rules 2016, Battery Waste Rules 2022.

• (a) Bio-medical Waste 1998 — handled by hospitals/generators, not producer responsibility.
• (b) Recycled Plastic 1999 — no EPR framework then.
• (d) FSS Regulations 2011 — food safety, unrelated to EPR.

Answer (c): Procurement incidentals and distribution cost. The ECONOMIC COST of foodgrains to the FOOD CORPORATION OF INDIA (FCI) is calculated as: MSP + Bonus (if any) paid to farmers + PROCUREMENT INCIDENTALS (handling, storage, gunny bags, labour, mandi charges, etc.) + DISTRIBUTION COST (transport to FPS, storage at godowns, handling loss, administrative costs).

• (a) Transportation cost ONLY — incomplete; economic cost covers more.
• (b) Interest cost ONLY — incomplete.
• (c) Procurement incidentals AND distribution cost ✓ — the comprehensive accounting identity.
• (d) Procurement incidentals + godown charges — misses distribution cost.

Answer (d): The level of mutual trust and harmony in the society. SOCIAL CAPITAL (concept by PIERRE BOURDIEU, ROBERT PUTNAM, JAMES COLEMAN) refers to the NETWORKS, NORMS, TRUST, and RECIPROCITY that enable cooperation for mutual benefit within a society. Key components: mutual trust, shared values, civic engagement, social cohesion. NOT physical capital, NOT human capital, NOT financial capital.

• (a) Proportion of literates = HUMAN CAPITAL.
• (b) Stock of buildings/infrastructure/machines = PHYSICAL CAPITAL.
• (c) Working-age population = DEMOGRAPHIC DIVIDEND / HUMAN RESOURCES.
• (d) Mutual trust and harmony in society ✓ = SOCIAL CAPITAL (Putnam's definition).

Answer (b): Lead Bank Scheme. The SERVICE AREA APPROACH (SAA), introduced in 1989 on the recommendation of the GOIPORIA COMMITTEE, was implemented UNDER THE PURVIEW OF THE LEAD BANK SCHEME (LBS, introduced 1969 following D.R. Gadgil Study Group + Nariman Committee). Each commercial bank was allotted a SPECIFIC SERVICE AREA (group of villages) for credit planning and branch expansion. SAA aimed to ensure equitable rural banking coverage.

• (a) IRDP — integrated rural development (poverty alleviation), different scheme.
• (c) MGNREGS — employment guarantee, different scheme.
• (d) National Skill Development Mission — skilling, unrelated.

Answer (a): 1 and 3 only. Minor minerals management under MMDR Act:

• S1 CORRECT — SAND IS A 'MINOR MINERAL' under Section 3(e) of the MMDR Act 1957 (along with building stones, ordinary clay, etc.) — classified by notification ✓.
• S2 WRONG — Under the MMDR Act, STATE GOVERNMENTS have the POWER TO MAKE RULES regarding GRANT of MINOR MINERAL leases (Section 15) — NOT the Central Government. Classic Centre-State jurisdiction swap. For major minerals, Centre makes rules; for minor minerals, States make rules.
• S3 CORRECT — State Governments HAVE THE POWER TO FRAME RULES TO PREVENT ILLEGAL MINING of minor minerals (under Section 15A of MMDR Act) ✓.

Answer (d): Neither 1 nor 2.

• S1 WRONG — India's external debt is NOT majority owed by governmental entities. Approximately 80% OF INDIA'S EXTERNAL DEBT IS FROM NON-GOVERNMENTAL/PRIVATE SECTOR SOURCES (NRI deposits, commercial borrowings by corporates, trade credits); only ~20% is sovereign/government debt. The 'most owed by government' claim is inverted.
• S2 WRONG — NOT ALL of India's external debt is DENOMINATED IN US DOLLARS. It is MULTI-CURRENCY: USD, INR, SDR, EUR, YEN, GBP, etc. USD has the LARGEST share (~50%+) but not all. Classic exclusive-currency claim.

Answer (b): Deposits. COMMERCIAL BANK's BALANCE SHEET:

• ASSETS — what the bank OWNS/IS OWED: Cash with RBI, Balances with other banks, INVESTMENTS (in govt securities etc.), ADVANCES (loans to customers), MONEY AT CALL AND SHORT NOTICE, fixed assets.
• LIABILITIES — what the bank OWES: Deposits (from customers), Borrowings, Capital, Reserves.

DEPOSITS are LIABILITIES (the bank owes the depositor their money back), NOT ASSETS. The other three options are all assets.

• (a) Advances ✓ — Asset (loans made by bank).
• (b) Deposits ✗ — LIABILITY, not asset (answer).
• (c) Investments ✓ — Asset.
• (d) Money at call and short notice ✓ — Asset.

Answer (b): 1 and 3 only. Reducing currency crisis risk (depreciation pressure):

• S1 CORRECT — India's IT sector generates SIGNIFICANT FOREIGN CURRENCY EARNINGS (software services exports ~$150+ bn annually), strengthening forex reserves and the rupee → REDUCES currency-crisis risk ✓.
• S2 WRONG — Increased GOVERNMENT EXPENDITURE typically INCREASES fiscal deficit, fuels inflation, can worsen the current account deficit, and PUT DOWNWARD PRESSURE on the rupee — NOT reducing currency-crisis risk. Classic direction inversion.
• S3 CORRECT — REMITTANCES from Indians abroad (India is the world's largest recipient, ~$80+ bn) are a MAJOR source of forex inflows, strengthening external balance → REDUCES currency-crisis risk ✓.

Answer (c): Sarkaria Commission (1983). The SARKARIA COMMISSION (1983-88, chaired by Justice R.S. Sarkaria) on Centre-State Relations recommended that the GOVERNOR should be:

• An EMINENT PERSON FROM OUTSIDE THE STATE (to avoid local political biases).
• A DETACHED FIGURE WITHOUT INTENSE POLITICAL LINKS.
• Should NOT have TAKEN PART IN POLITICS in the recent past.

Aim: to ensure the Governor acts as a neutral constitutional head, not a political agent. Reiterated by the Punchhi Commission (2010).

• (a) First ARC (1966) — Morarji Desai/K. Hanumanthaiah, broader administrative reforms, not this specific Governor recommendation.
• (b) Rajamannar Committee (1969) — Tamil Nadu state-sponsored, pro-autonomy proposals, different focus.
• (d) NCRWC (2000) — reviewed but didn't originate this recommendation.

Answer (d): Participatory Note. PARTICIPATORY NOTES (P-NOTES or ODIs — OFFSHORE DERIVATIVE INSTRUMENTS) are issued by REGISTERED FOREIGN PORTFOLIO INVESTORS (FPIs) to OVERSEAS INVESTORS who want EXPOSURE TO INDIAN SECURITIES WITHOUT DIRECTLY REGISTERING with SEBI. The FPI holds the underlying Indian security; the overseas investor holds a P-Note whose returns mirror the security's returns. Historically controversial due to opacity about underlying beneficial owner (anti-money-laundering concerns).

• (a) Certificate of Deposit — short-term bank-issued instrument, unrelated to FPI access.
• (b) Commercial Paper — corporate short-term borrowing, unrelated.
• (c) Promissory Note — generic debt instrument.

Answer (a): 1 only.

• S1 CORRECT — Under the Compensatory Afforestation Fund Act, 2016 (operationalised through CAMPA rules 2018), the COMPENSATORY AFFORESTATION FUND MANAGEMENT AND PLANNING AUTHORITY (CAMPA) exists at BOTH NATIONAL (National CAMPA) AND STATE LEVELS (State CAMPA) ✓.
• S2 WRONG — The CAF Act 2016 does NOT make PEOPLE'S PARTICIPATION MANDATORY in compensatory afforestation programmes. Implementation is largely top-down through Forest Department structures; community participation is encouraged but not statutorily mandatory. Critics (tribal rights activists) have pointed to this gap.

Answer (a): 1 and 2. IN INDIA, INDEPENDENT REGULATORS (SEBI, TRAI, IRDAI, CERC, PNGRB, etc.) are MONITORED BY PARLIAMENTARY OVERSIGHT THROUGH:

• 1. AD HOC COMMITTEES SET UP BY PARLIAMENT ✓ — Parliament can set up JPCs, Select Committees to examine regulator's conduct/policies.
• 2. DEPARTMENT-RELATED PARLIAMENTARY STANDING COMMITTEES ✓ — 24 DRPSCs oversee ministries AND the regulators under those ministries (e.g., DRPSC on Finance for SEBI/IRDAI; DRPSC on IT for TRAI).
• 3. Finance Commission ✗ — deals with Centre-State fiscal federalism, not regulator monitoring.
• 4. FSLRC (Financial Sector Legislative Reforms Commission) ✗ — was a one-time commission (2013 report), not an ongoing monitor.
• 5. NITI Aayog ✗ — think tank for policy, not a monitor of regulators.

Answer (a): 1 and 2 only. India's Five-Year Plans:

• S1 CORRECT — The SECOND FIVE-YEAR PLAN (1956-61, MAHALANOBIS MODEL) had a DETERMINED THRUST towards SUBSTITUTION OF BASIC AND CAPITAL GOODS INDUSTRIES (heavy industry-led growth, Nehruvian socialism, PSU-led industrialisation) ✓.
• S2 CORRECT — The FOURTH FIVE-YEAR PLAN (1969-74) EXPLICITLY adopted the objective of CORRECTING THE EARLIER TREND OF INCREASED CONCENTRATION OF WEALTH AND ECONOMIC POWER — along with 'Growth with Justice', Garibi Hatao themes. Indira Gandhi-era planning reflected these concerns ✓.
• S3 WRONG — The FIFTH FIVE-YEAR PLAN (1974-78) did NOT include the FINANCIAL SECTOR as an integral part of the Plan for the first time. Financial sector integration was a later reform-era development (post-1991 LPG). The claim is inaccurate.

Answer (d): Neither 1 nor 2.

• S1 WRONG — HIGH COURTS DO HAVE JURISDICTION to DECLARE A CENTRAL LAW constitutionally invalid if it violates the Constitution (Articles 13, 32, 226 empower HCs to strike down unconstitutional laws — both central and state). The 'no HC jurisdiction' claim is fundamentally wrong. In fact, HC powers of judicial review are part of basic structure.
• S2 WRONG — An AMENDMENT TO THE CONSTITUTION CAN BE CHALLENGED in the Supreme Court of India — particularly if it violates the BASIC STRUCTURE DOCTRINE (Kesavananda Bharati 1973). Many amendments have been struck down (e.g., 99th Amendment NJAC, 2015). The 'cannot be called into question' claim is absolutely wrong.

Answer (a): 1 only.

• S1 CORRECT — PURCHASING POWER PARITY (PPP) EXCHANGE RATES are computed by COMPARING THE COST OF A SAME BASKET OF GOODS AND SERVICES in different countries ✓ — the foundational methodology (Big Mac Index, World Bank ICP, etc.).
• S2 WRONG — In PPP terms, INDIA IS the THIRD-LARGEST ECONOMY in the world (after China and the USA) as per IMF/World Bank rankings in 2018-19 — NOT the sixth largest. In NOMINAL GDP, India is around 6th-7th; in PPP, India has been 3rd since ~2011. Classic nominal-vs-PPP ranking confusion.

Answer (a): 1 and 3 only. Kharif crops area (past 5 years):

• S1 CORRECT — AREA UNDER RICE CULTIVATION is the HIGHEST among kharif crops (~40 million hectares) ✓.
• S2 WRONG — Area under JOWAR cultivation (~2-3 million ha) is LESS THAN that of OILSEEDS (kharif oilseeds total ~17-18 million ha including groundnut, soyabean, etc.). S2 inverts the ranking.
• S3 CORRECT — Area under COTTON cultivation (~12-13 million ha) is MORE THAN that of SUGARCANE (~5 million ha) ✓.
• S4 WRONG — Area under SUGARCANE has NOT STEADILY DECREASED — it has been relatively stable around 5 million ha (with year-to-year fluctuations). 'Steadily decreased' is the PDF's flagged trend-word that's usually wrong.

Answer (d): Vegetable oils. Among India's agricultural IMPORTS by VALUE in the last five years, VEGETABLE OILS (palm oil from Indonesia/Malaysia, soybean oil from Argentina/Brazil, sunflower oil from Russia/Ukraine) account for the HIGHEST VALUE — typically $10-12 billion annually. India imports ~60-70% of its edible oil consumption. Pulses come second (periodically high), then spices, then fresh fruits.

• (a) Spices — India is NET EXPORTER of spices, not importer.
• (b) Fresh fruits — small import value.
• (c) Pulses — significant import but less than edible oils.
• (d) Vegetable oils ✓ — the largest agricultural import by value.

Answer (d): Opportunity to develop oneself fully. The POSITIVE (OR CONSTRUCTIVE) CONCEPTION OF LIBERTY defines it not as the mere absence of restraints but as the POSITIVE OPPORTUNITY TO DEVELOP ONESELF FULLY, to realise one's capacities and to be one's own master (T.H. Green, Harold Laski). This is the most appropriate polity-philosophy definition: liberty enables self-realisation.

• (a) Protection against tyranny — a specific political safeguard, not the definitional essence.
• (b) Absence of restraint — NEGATIVE conception (Isaiah Berlin's 'negative liberty'), but incomplete on its own.
• (c) 'Opportunity to do whatever one likes' — license, not liberty (classical distinction).
• (d) Opportunity to develop oneself fully ✓ — positive liberty, canonical polity-theory answer.

Answer (d): Following an expansionary monetary policy. The question asks what is NOT a typical measure to STOP THE SLIDE of the INDIAN RUPEE:

• (a) Curbing imports + promoting exports — TYPICAL remedy (reduces CAD, narrows forex demand-supply gap) ✓ usual measure.
• (b) Encouraging Masala Bonds — TYPICAL remedy (Masala Bonds raise rupee-denominated funds abroad, bringing in forex) ✓ usual measure.
• (c) Easing ECB conditions — TYPICAL remedy (attracts dollar inflows, eases forex supply) ✓ usual measure.
• (d) EXPANSIONARY monetary policy ✗ — This would INCREASE money supply / lower interest rates → typically WEAKENS the currency (capital outflows, inflation), WORSENING rupee depreciation. To DEFEND the rupee, CONTRACTIONARY monetary policy (higher rates) is needed.

Answer (a): 1 only. RBI's 2018 'DATA LOCALIZATION' directive (STORAGE OF PAYMENT SYSTEM DATA) for payment system providers:

• S1 CORRECT — Payment system providers SHALL ENSURE that the ENTIRE DATA RELATING TO PAYMENT SYSTEMS operated by them ARE STORED IN A SYSTEM ONLY IN INDIA (data localisation for payment systems) ✓.
• S2 WRONG — RBI's directive does NOT require the systems to be OWNED AND OPERATED by PUBLIC SECTOR ENTERPRISES. It's ownership-neutral; private/foreign payment providers (Visa, Mastercard, Amex) are covered, they just need to localise data storage. The 'public sector' claim is fabricated.
• S3 WRONG — The directive does NOT require submission of System Audit Report to the CAG (Comptroller and Auditor General). Reports go to RBI itself (not CAG), and the audit is by CERT-In empaneled auditors, not CAG. Classic institutional-attribution manipulation.

Answer (c): The European Union. The GENERAL DATA PROTECTION REGULATION (GDPR) was ADOPTED BY THE EUROPEAN UNION in April 2016 and BECAME ENFORCEABLE ON 25 MAY 2018. GDPR is a comprehensive data-protection law applying to all EU residents' personal data, with extraterritorial reach (any company processing EU residents' data must comply, regardless of location). Penalties up to 4% of global turnover or €20 million.

• (a) Australia — has separate Privacy Act.
• (b) Canada — has PIPEDA.
• (d) USA — has sector-specific laws (HIPAA, CCPA for California), but no federal law like GDPR.

Answer (b): Russia. The 'ACTION PLAN FOR PRIORITIZATION AND IMPLEMENTATION OF COOPERATION AREAS IN THE NUCLEAR FIELD' was signed between INDIA and RUSSIA during PM Modi's visit to Russia in October 2018 (Annual Bilateral Summit). It aims at DEEPER COOPERATION in civil nuclear energy — including construction of additional reactors at Kudankulam (Units 5 and 6), and building the second nuclear power plant site in India.

• (a) Japan — has India-Japan civil nuclear agreement (2017), but this specific 'Action Plan' is Russia.
• (c) UK — has civil nuclear cooperation agreement but not this specific document.
• (d) USA — has the 2008 India-US nuclear deal, but not this 2018 Action Plan.

Answer (b): Increase in the banking habit of the population. The MONEY MULTIPLIER = (Money Supply) / (Monetary Base) = 1 / [reserve ratio + currency-deposit ratio * (1-reserve ratio)]. It INCREASES when:

• People HOLD MORE DEPOSITS IN BANKS and LESS CURRENCY — i.e., the BANKING HABIT INCREASES. Deposits are subject to fractional reserve lending, so more deposits = more credit creation = higher multiplier.
• CRR/SLR FALL — more lendable funds with banks.
• (a) Increase in CRR → DECREASES multiplier (more reserves locked up).
• (b) Increase in banking habit → INCREASES multiplier ✓.
• (c) Increase in SLR → DECREASES multiplier.
• (d) Population increase → doesn't directly affect multiplier.

Answer (c): 1, 2 and 4. Particularly Vulnerable Tribal Groups (PVTGs):

• 1. CORRECT — PVTGs reside in 18 STATES AND ONE UNION TERRITORY (Andaman & Nicobar) ✓.
• 2. CORRECT — A STAGNANT OR DECLINING POPULATION is indeed one of the 4 CRITERIA for PVTG status (along with pre-agricultural technology, low literacy, subsistence economy) established by Dhebar Commission ✓.
• 3. WRONG — There are 75 PVTGs officially notified (NOT 95). Specific-number manipulation.
• 4. CORRECT — TODA (Nilgiris, Tamil Nadu) and KONDA REDDI (Andhra Pradesh/Telangana) tribes are both INCLUDED in the PVTG list ✓ (though Q says 'Trular' — likely typo for Toda).

Answer (b): The Supreme Court of India is not constrained in the exercise of its powers by laws made by the Parliament. ARTICLE 142 of the Constitution empowers the Supreme Court to PASS ANY DECREE or MAKE ANY ORDER NECESSARY FOR DOING COMPLETE JUSTICE in any cause or matter. The question's statement that 'prohibitions/limitations in ordinary laws cannot limit Article 142 powers' means the SC is NOT BOUND BY ORDINARY STATUTORY PROVISIONS when invoking Article 142 to do complete justice. Key cases: Supreme Court Bar Association v. UoI (1998), Prem Chand Garg (1963).

• (a) Election Commission decisions — covered by Art 324, separate jurisprudence.
• (c) Financial Emergency — Art 360, separate, needs Cabinet advice normally.
• (d) State Legislature concurrence — doesn't relate to Art 142.

Answer (c): Both 1 and 2.

• S1 CORRECT — The GOVERNOR makes a CUSTOMARY ADDRESS to both Houses (or the single House for unicameral states) at the COMMENCEMENT OF THE FIRST SESSION of each year (Article 176 for Governor's address — modelled on the President's address under Article 87). This sets out the state government's programme ✓.
• S2 CORRECT — When a STATE LEGISLATURE DOES NOT HAVE A RULE on a particular matter, IT FOLLOWS THE LOK SABHA RULE on that matter. This is a standard parliamentary convention — state legislatures typically model their procedures on Parliament's, defaulting to Parliament's rules in gaps ✓.

Answer (c): 2 and 4 only.

• S1 WRONG — The SMUGGLING OF MIGRANTS Protocol is a PROTOCOL TO THE UN CONVENTION AGAINST TRANSNATIONAL ORGANIZED CRIME (UNTOC), NOT to UNCAC. Classic instrument swap.
• S2 CORRECT — UNCAC (adopted 2003) IS THE FIRST LEGALLY BINDING GLOBAL ANTI-CORRUPTION INSTRUMENT ✓.
• S3 WRONG — The CHAPTER ON ASSET RETURN is a HIGHLIGHT OF UNCAC (Chapter V), NOT UNTOC. UNTOC deals with organised crime; UNCAC specifically contains the asset-recovery framework. Classic instrument-feature swap.
• S4 CORRECT — UNODC (UN Office on Drugs and Crime) is MANDATED BY ITS MEMBER STATES TO ASSIST in the implementation of BOTH UNCAC AND UNTOC ✓.

Answer (b): 2 and 3 only.

• S1 WRONG — The 2017 amendment to the INDIAN FOREST ACT, 1927 EXEMPTED BAMBOO GROWN OUTSIDE FOREST AREAS from the definition of 'tree' — so it can be felled without permit on non-forest land. But WITHIN FOREST AREAS, bamboo-felling rights still depend on forest rules / FRA provisions — not a blanket right. The 'forest dwellers have right to fell bamboos on forest areas' wording is overbroad; actual amendment was narrower.
• S2 CORRECT — Under the Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006, BAMBOO IS CATEGORIZED AS A MINOR FOREST PRODUCE (MFP) ✓ — a significant reform enabling tribal livelihoods.
• S3 CORRECT — The FRA 2006 ALLOWS OWNERSHIP OF MINOR FOREST PRODUCE to forest dwellers (Section 3(1)(c)) ✓ — a key empowerment provision.

Answer (b): Article 21. The RIGHT TO MARRY A PERSON OF ONE'S CHOICE is protected under ARTICLE 21 (Right to Life and Personal Liberty), as elaborated by the Supreme Court in SHAFIN JAHAN v. ASOKAN K.M. (Hadiya case, 2018) and other cases. The SC held that CHOICE OF PARTNER is intrinsic to the right to life and personal liberty — autonomy, dignity, privacy (post-Puttaswamy 2017) all subsume the right to marry.

• (a) Art 19 — freedoms of speech, assembly, etc., not marriage.
• (c) Art 25 — religious freedom, not marriage as such.
• (d) Art 29 — cultural-educational rights of minorities, not marriage.

Answer (c): 3 only.

• S1 WRONG — Under the INDIAN PATENTS ACT, 1970 Section 3(j), BIOLOGICAL PROCESSES for the production or propagation of plants and animals (including seed creation) are NOT PATENTABLE IN INDIA. Classic inversion.
• S2 WRONG — India HAS an INTELLECTUAL PROPERTY APPELLATE BOARD (IPAB), set up in 2003 under the Trade Marks Act 1999 (later merged with Tribunal Reforms Act 2021). In 2019, IPAB was still operational. The 'no IPAB' claim is factually wrong at the time of the question.
• S3 CORRECT — PLANT VARIETIES are NOT ELIGIBLE FOR PATENTS in India. They are protected under a SUI GENERIS system — the PROTECTION OF PLANT VARIETIES AND FARMERS' RIGHTS (PPV&FR) ACT, 2001 — not the Patents Act ✓.

Answer (b): 2 only. Environment Protection Act, 1986 empowers the Centre to:

• S1 WRONG — The EP Act 1986 does NOT mandate/require PUBLIC PARTICIPATION as a statutory feature of environmental decision-making. Public consultation came in later through EIA Notifications (2006) and judicial interventions, not the original Act. S1 overstates Act's scope.
• S2 CORRECT — Section 3(2)(iv) of the EP Act 1986 specifically empowers the Centre to 'LAY DOWN STANDARDS FOR EMISSION OR DISCHARGE OF ENVIRONMENTAL POLLUTANTS from various sources' ✓ — a core statutory power exercised through CPCB standards.

Answer (c): The Rules provide for exact and elaborate criteria for the identification of the sites for landfills and waste processing facilities. Solid Waste Management Rules, 2016:

• (a) WRONG — Waste-generators are required to segregate waste into THREE categories (wet/biodegradable, dry/recyclable, domestic hazardous), NOT five. Specific-number manipulation.
• (b) WRONG — The Rules apply to ALL URBAN LOCAL BODIES, CENSUS TOWNS, notified urban areas, industrial townships, areas under Central/State control — NOT 'ONLY notified urban areas'. Too restrictive.
• (c) CORRECT — The Rules PROVIDE EXACT AND ELABORATE CRITERIA for IDENTIFICATION OF SITES FOR SANITARY LANDFILLS AND WASTE PROCESSING FACILITIES (distance from habitations, water bodies, airports, etc.) ✓ — Rule 11 and Schedule I of the 2016 Rules.
• (d) WRONG — Inter-district transfer of waste is NOT prohibited; the Rules allow it with proper protocols.

Answer (c): Both 1 and 2. Industrial Employment (Standing Orders) Central (Amendment) Rules, 2018:

• S1 CORRECT — The amendment INTRODUCED FIXED-TERM EMPLOYMENT across all industries — this makes it EASIER FOR FIRMS TO LAY OFF WORKERS at the end of contract (no notice required for fixed-term contract expiry) ✓.
• S2 CORRECT — Under the rules, NO NOTICE OF TERMINATION is required in the case of a TEMPORARY WORKMAN (since employment ends at the contract's natural termination). S2 captures this correctly ✓.

Critics argue these changes favour industry over labour; defenders argue they formalise short-term employment patterns.

Answer (b): 3 and 4 only. AR vs VR definitions:

• S1 WRONG — In AUGMENTED REALITY (AR), digital content is OVERLAID ON THE REAL WORLD (camera view) — the physical world is NOT SHUT OUT (examples: Pokémon Go, Snapchat filters). The statement swaps AR with VR. Classic tech-concept inversion.
• S2 WRONG — In VIRTUAL REALITY (VR), a COMPLETELY SIMULATED environment is created — NOT real-life object projection. The 'images projected onto real-life objects' description fits AR, not VR. Classic tech-concept inversion.
• S3 CORRECT — AR ALLOWS INDIVIDUALS TO BE PRESENT IN THE REAL WORLD and IMPROVES THE EXPERIENCE USING CAMERA of smart-phone/PC ✓.
• S4 CORRECT — VR CLOSES THE WORLD and TRANSPOSES AN INDIVIDUAL to a virtual environment, providing COMPLETE IMMERSION ✓.

Answer (b): An early human species. DENISOVANS are an EXTINCT ARCHAIC HUMAN SPECIES (hominin), identified in 2010 from DNA extracted from a finger bone discovered in DENISOVA CAVE in the Altai Mountains of Siberia. They lived alongside Neanderthals and interbred with modern humans. Traces of Denisovan DNA are found in modern Papuan, Melanesian, Aboriginal Australian and some East Asian populations.

• (a) Dinosaur fossils — no.
• (c) Cave system in NE India — no (Denisova is in Siberia).
• (d) Geological period — no.

Answer (a): Functional chromosomes can be created by joining segments of DNA taken from cells of different species. (This is the INCORRECT statement — the Q asks which is NOT correct.)

• (a) WRONG — Creating FULLY FUNCTIONAL CHROMOSOMES by joining DNA segments from different species is NOT YET ACHIEVED — synthetic biology has produced simpler synthetic DNA constructs, but complete inter-species functional chromosome assembly remains beyond current tech. This is the 'not correct' claim the Q asks about ✓.
• (b) Pieces of ARTIFICIAL FUNCTIONAL DNA can be created in laboratories ✓ (J. Craig Venter Institute's Mycoplasma mycoides JCVI-syn1.0 in 2010; synthetic DNA sequences routinely manufactured).
• (c) A piece of DNA taken out from an animal cell can be made to REPLICATE OUTSIDE a living cell (via PCR and cell-free replication) ✓.
• (d) Cells from plants/animals can be made to UNDERGO CELL DIVISION in petri dishes (tissue culture is standard) ✓.

Answer (c): 3 only. Digital signature (under IT Act 2000):

• S1 WRONG — A digital signature is NOT primarily an 'electronic record that identifies the CERTIFYING AUTHORITY issuing it'. The DIGITAL SIGNATURE CERTIFICATE (DSC) identifies the subscriber. The certifying authority is identified separately. S1 conflates concepts.
• S2 WRONG — Digital signature is NOT designed as a PROOF OF IDENTITY TO ACCESS SERVERS on Internet per se. It's used for SIGNING electronic documents (authenticity and integrity). Access control uses separate authentication (password, OTP). The 'server access' framing is misleading.
• S3 CORRECT — A digital signature IS an ELECTRONIC METHOD OF SIGNING AN ELECTRONIC DOCUMENT and ENSURING THAT THE ORIGINAL CONTENT IS UNCHANGED (integrity via cryptographic hash) ✓.

Answer (d): 1, 2 and 3. Wearable technology applications — all three are well-established:

• 1. LOCATION IDENTIFICATION ✓ — GPS-enabled smartwatches, fitness trackers, wearable trackers for pets, children, elderly.
• 2. SLEEP MONITORING ✓ — fitness bands (Fitbit, Apple Watch, Oura Ring) track sleep stages, duration, quality using accelerometer + heart rate.
• 3. ASSISTING THE HEARING IMPAIRED ✓ — modern hearing aids (Bluetooth-enabled), cochlear implants, vibration-alert wearables for the deaf.

Answer (a): 1, 2 and 4. RNA Interference (RNAi) applications:

• S1 CORRECT — RNAi IS used in GENE-SILENCING THERAPIES (small interfering RNAs, siRNAs, silence target gene expression) ✓. Patisiran (for hATTR amyloidosis) was the first FDA-approved siRNA drug (2018).
• S2 CORRECT — RNAi has therapeutic potential for CANCER TREATMENT (silencing oncogenes, drug-resistance genes) — multiple clinical trials ongoing ✓.
• S3 WRONG — RNAi is NOT used in HORMONE REPLACEMENT THERAPIES. HRT uses synthetic or biological hormones (estrogen, testosterone, thyroid hormone), not RNA interference.
• S4 CORRECT — RNAi is used in AGRICULTURAL BIOTECHNOLOGY to produce VIRUS-RESISTANT CROP PLANTS (transgenic plants expressing siRNAs that silence viral genes) ✓.

Answer (b): 'Gravitational waves' were detected. The MERGER of BINARY BLACK HOLES is the PRIMARY SOURCE of detectable GRAVITATIONAL WAVES. The first direct detection was by LIGO on 14 September 2015 (announced 2016) — observing GW150914, the merger of two black holes 1.3 billion light-years away. Subsequent detections (including neutron-star mergers) have confirmed Einstein's general relativity prediction. The 2019 era of multi-messenger astronomy is built on these detections.

• (a) Higgs boson — detected at LHC (CERN, 2012), different experiment.
• (c) Wormhole travel — no empirical confirmation.
• (d) Singularity understanding — still an open problem in physics.

Answer (b): 2 and 3 only. Multi-drug resistance (MDR) in pathogens — causes:

• S1 WRONG — Genetic predisposition of some PEOPLE is NOT a cause of MDR in pathogens. MDR arises from bacterial evolution/selection pressure, NOT human genetic predisposition. Classic human-pathogen confusion.
• S2 CORRECT — INCORRECT DOSES of ANTIBIOTICS (incomplete courses, sub-therapeutic doses, self-medication) drive MDR by selecting for resistant strains ✓.
• S3 CORRECT — Using ANTIBIOTICS IN LIVESTOCK FARMING (growth promoters, prophylactic use) is a MAJOR driver of MDR — antibiotic residues in meat + environmental runoff → resistance in human pathogens ✓.
• S4 WRONG — CHRONIC DISEASES in people don't directly cause pathogen MDR; they may increase individual infection risk but don't create resistance in the pathogen population.

Answer (a): A molecular scissors used in targeted gene editing. Cas9 PROTEIN is a CRISPR-ASSOCIATED ENDONUCLEASE (derived from bacterial immune system, notably Streptococcus pyogenes) that ACTS AS A 'MOLECULAR SCISSORS'. Guided by a short RNA sequence (guide RNA), Cas9 creates a precise double-stranded break in target DNA — enabling TARGETED GENE EDITING. This is the foundation of CRISPR-Cas9 gene editing (Doudna + Charpentier, 2012; 2020 Nobel Chemistry).

• (b) Biosensor — no.
• (c) Pest-resistance gene — no (that's Bt).
• (d) Herbicidal substance — no (that's glyphosate-family).

Answer (b): Hepatitis B, unlike hepatitis C, does not have a vaccine. (This is the INCORRECT statement — the Q asks which is NOT correct.)

• (a) CORRECT — Hepatitis B virus IS transmitted much like HIV (blood, sexual contact, mother-to-child) ✓.
• (b) WRONG ✓ — Statement is inverted! HEPATITIS B HAS A VACCINE (HepB vaccine, part of India's UIP since 2002-07). HEPATITIS C does NOT have a vaccine (only antivirals for treatment). The statement swaps the two — B has a vaccine, C doesn't.
• (c) CORRECT — Globally, Hepatitis B and C infected populations (~300 million + ~70 million) are many times more than HIV (~38 million) ✓.
• (d) CORRECT — Hepatitis B/C infections often show no symptoms for years (asymptomatic chronic carriers) ✓.

Answer (d): Neither 1 nor 2. Jagirdar vs Zamindar under Mughal India:

• S1 WRONG — JAGIRDARS were holders of LAND ASSIGNMENTS (JAGIRS) in LIEU OF MILITARY SERVICE — they were mansabdars whose salary was paid via jagir's revenue, not 'judicial and police duties'. Jagirs were non-hereditary, regularly transferred. Also, ZAMINDARS had HEREDITARY revenue rights but also responsibilities (revenue collection, maintaining local order) — not 'without obligation'. S1 misrepresents both roles.
• S2 WRONG — Land assignments to JAGIRDARS were NOT HEREDITARY — they were regularly TRANSFERRED (to prevent entrenchment) under the Mughal mansabdari system. ZAMINDARS' revenue rights WERE typically HEREDITARY. S2 inverts both.

Answer (b): The major aim of land reforms was providing agricultural land to all the landless. Land reforms in independent India (1950s-70s) had multiple components: abolition of intermediaries (zamindari), tenancy reforms, ceiling on landholdings, consolidation of holdings, and Bhoodan-Gramdan movement. The MAJOR STATED AIM was to REDUCE LAND CONCENTRATION and PROVIDE AGRICULTURAL LAND TO THE LANDLESS (socialist-egalitarian thrust).

• (a) Wrong — ceiling laws applied to both family AND individual holdings (redefined over time).
• (b) CORRECT — providing land to the landless was the overarching redistributive goal ✓.
• (c) Wrong — reforms didn't promote cash crops; Green Revolution later did.
• (d) Wrong — ceiling laws HAD EXEMPTIONS (for plantations, religious/educational institutions, etc.).

Answer (c): World Economic Forum. The GLOBAL COMPETITIVENESS REPORT (GCR) is published annually by the WORLD ECONOMIC FORUM (WEF) — since 1979. It ranks countries on the Global Competitiveness Index (GCI), based on 12 pillars (institutions, infrastructure, macroeconomic stability, health, skills, product market, labour market, financial system, market size, business dynamism, innovation capability, etc.).

• (a) IMF — publishes World Economic Outlook, Fiscal Monitor, not GCR.
• (b) UNCTAD — publishes Trade and Development Report, World Investment Report, not GCR.
• (d) World Bank — publishes Doing Business Report, World Development Report, not GCR.

Answer (a): 1 and 2 only. Charter Act 1813:

• S1 CORRECT — The Charter Act 1813 ENDED THE EAST INDIA COMPANY's TRADE MONOPOLY IN INDIA — opening India to private British merchants — EXCEPT for the MONOPOLY OF TEA TRADE AND TRADE WITH CHINA (these continued with EIC) ✓.
• S2 CORRECT — The Charter Act 1813 ASSERTED THE SOVEREIGNTY OF THE BRITISH CROWN over the Indian territories held by the Company — an explicit declaration distinguishing Company-acquired territories from Crown sovereignty ✓.
• S3 WRONG — The revenues of India were NOT YET controlled by the British Parliament under the 1813 Act. This happened later under the GoI Act 1858 (when Crown took over direct administration from the Company). 1813 maintained the Company's revenue/administrative role, but subject to Board of Control.

Answer (c): Both 1 and 2. Swadeshi Movement (1905-08):

• S1 CORRECT — The Swadeshi movement CONTRIBUTED TO THE REVIVAL OF INDIGENOUS ARTISAN CRAFTS AND INDUSTRIES — promoting khadi, handloom weaving, soap, matches, iron and steel ventures (Tata Iron and Steel, 1907) ✓.
• S2 CORRECT — The NATIONAL COUNCIL OF EDUCATION (NCE) was ESTABLISHED IN AUGUST 1906 as an integral part of the Swadeshi movement — promoting indigenous education (Bengal National College 1906, National Council of Education Bengal was founded). Aurobindo Ghosh headed the Bengal National College ✓.

Answer (d): 1, 2 and 3. Movement/Organisation — Leader pairs:

• 1. All India Anti-Untouchability League — MAHATMA GANDHI ✓ — Founded in 1932 by Gandhi (renamed Harijan Sevak Sangh in September 1932) after the Poona Pact; aimed at abolishing untouchability ✓.
• 2. All India Kisan Sabha — SWAMI SAHAJANAND SARASWATI ✓ — Founded in 1936 (Lucknow) with Sahajanand Saraswati as its first president, aimed at organising peasant movements ✓.
• 3. Self-Respect Movement — E.V. RAMASWAMI NAICKER (PERIYAR) ✓ — Founded 1925 in Tamil Nadu; anti-caste, anti-Brahmin, Dravidian-pride movement ✓.

All three pairings are correctly matched.

Answer (c): Sohgaura. Harappan sites:

• (a) CHANHUDARO ✓ — Harappan site in Sindh (Pakistan), known for bead-making.
• (b) KOT DIJI ✓ — Early Harappan/Pre-Harappan site in Sindh, Pakistan; Kot Dijian culture precedes mature Harappan.
• (c) SOHGAURA ✗ NOT A HARAPPAN SITE — Sohgaura is in Gorakhpur district, UTTAR PRADESH. It is famous for the SOHGAURA COPPER PLATE INSCRIPTION (~3rd century BCE) — one of the EARLIEST KNOWN INSCRIPTIONS in India (Mauryan era), dealing with famine relief. This is NOT a Harappan site.
• (d) DESALPUR ✓ — Harappan site in Kutch region, Gujarat.

Answer (a): Kanganahalli. KANGANAHALLI (Karnataka, near Sannati in Gulbarga district) is a BUDDHIST SITE where an INSCRIBED RELIEF SCULPTURE was discovered (excavations 1994-98). It shows a PORTRAIT OF EMPEROR ASHOKA along with a BRAHMI INSCRIPTION reading 'RANYO ASOKO' (King Ashoka) — making it the ONLY KNOWN STONE PORTRAIT OF ASHOKA accompanied by his name inscription. Dated to ~1st century BCE. A crucial find in Mauryan art history.

• (b) Sanchi — famous Buddhist stupa, but no Ashoka portrait with inscription.
• (c) Shahbazgarhi — Ashokan rock edict site (Pakistan), no portrait.
• (d) Sohgaura — Mauryan copper plate, no portrait.

Answer (d): 1, 2 and 3. Mahayana Buddhism distinctive features (vs Hinayana/Theravada):

• 1. DEIFICATION OF THE BUDDHA ✓ — Mahayana elevated the Buddha from a historical teacher to a transcendent divine figure (dharmakaya, sambhogakaya), worshipped with devotion.
• 2. TREADING THE PATH OF BODHISATTVAS ✓ — Core Mahayana doctrine: aspire to become a Bodhisattva (enlightened being who delays nirvana to help others) rather than seek individual Arhatship. Emphasis on compassion.
• 3. IMAGE WORSHIP AND RITUALS ✓ — Mahayana introduced statue/image worship (Buddha images, Bodhisattva images), elaborate rituals, temple worship — distinct from original Theravada's more austere practice.

Answer (a): It was considered a source of income for the State, a sort of tax paid by the people. VISHTI (forced labour) in the GUPTA PERIOD (c. 320-550 CE):

• (a) CORRECT — Vishti was CONSIDERED A SOURCE OF INCOME FOR THE STATE — a FORM OF TAX PAID IN THE FORM OF LABOUR by rural peasantry (instead of money or grain). Cultivators had to render unpaid labour services to the state (for irrigation works, construction) — akin to a labour tax ✓.
• (b) Wrong — Vishti was prevalent across Gupta territory including Madhya Pradesh and Kathiawar regions.
• (c) Wrong — Forced labourers were NOT entitled to wages (hence 'forced').
• (d) Wrong — There was no specific 'eldest son of labourer' rule.

Answer (a): Tobacco, cocoa and rubber. 'NEW WORLD' (Americas) plants domesticated and introduced to the 'OLD WORLD' (Afro-Eurasia):

• TOBACCO — domesticated in the Americas (Nicotiana spp.); introduced to Europe via Spanish/Portuguese contact, 16th century.
• COCOA (cacao) — domesticated in Mesoamerica (Theobroma cacao); introduced to Europe via Spanish conquistadors, 16th-17th century.
• RUBBER (Hevea brasiliensis) — native to the Amazon basin; introduced to Asia (Malaya, SE Asia) as plantation crop in 19th century.
• (b) — Cotton: actually cotton was domesticated BOTH in the Americas (upland cotton) AND Old World (Gossypium herbaceum); a mixed-origin crop.
• (c) — Coffee: OLD WORLD (Ethiopia), NOT New World.
• (d) — Wheat: OLD WORLD (Fertile Crescent), NOT New World.

Answer (a): 1 only.

• S1 CORRECT — The ASIATIC LION (Panthera leo persica) is NATURALLY FOUND IN INDIA ONLY — restricted to Gir National Park and surrounding areas in Gujarat. A small introduced population exists elsewhere but the natural wild habitat is only in India ✓.
• S2 WRONG — The DOUBLE-HUMPED CAMEL (Bactrian camel, Camelus bactrianus / Camelus ferus) is found NOT ONLY IN INDIA but primarily in MONGOLIA AND CENTRAL ASIA (wild Bactrians in Mongolia/China; domesticated Bactrians across Central Asia). In India, only a small population exists in LADAKH region. Not India-only.
• S3 WRONG — The ONE-HORNED RHINOCEROS (Indian Rhinoceros, Rhinoceros unicornis) is found in INDIA AND NEPAL (Kaziranga in Assam, Chitwan in Nepal) — NOT India-only.

Answer (a): 1 and 2 only. Famous place — river pairs:

• 1. Pandharpur — CHANDRABHAGA ✓ — Pandharpur in Maharashtra (famous Vithoba temple, Warkari pilgrimage) is on the banks of the CHANDRABHAGA (a name for the BHIMA river at Pandharpur, due to its crescent-moon shape) ✓.
• 2. Tiruchirappalli — CAUVERY ✓ — Tiruchirappalli (Trichy) in Tamil Nadu is on the Cauvery River (Ranganathaswamy Temple at Srirangam is situated on an island in the Cauvery) ✓.
• 3. Hampi — Malaprabha ✗ — Hampi (ancient Vijayanagara, Karnataka) is on the banks of the TUNGABHADRA RIVER, NOT Malaprabha. Classic river-swap trap.

Answer (b): Price levels vary from State to State. IN INDIA, OFFICIAL POVERTY LINES VARY BY STATE (though the Tendulkar/Rangarajan methodologies use state-specific thresholds). The primary reason for INTER-STATE VARIATION in poverty lines is that PRICE LEVELS (cost of consumption basket for basic necessities) VARY FROM STATE TO STATE. The poverty line is defined as the monetary equivalent of a fixed consumption basket (food + non-food); since the cost of that basket differs across states (higher in urban/developed states), poverty lines differ.

• (a) Poverty RATES vary — that's the outcome, not the reason for differing lines.
• (c) Gross State Product varies — doesn't determine poverty line.
• (d) PDS quality — affects subsidised distribution, not the poverty line itself.

Answer (d): Reducing the global warming. CIRRUS CLOUD THINNING and SULPHATE AEROSOL INJECTION INTO THE STRATOSPHERE are both SOLAR RADIATION MANAGEMENT (SRM) / GEOENGINEERING techniques proposed by some scientists to REDUCE GLOBAL WARMING:

• Cirrus cloud thinning — reduces high-altitude cirrus clouds, which trap outgoing infrared radiation; thinning them lets more heat escape to space.
• Sulphate aerosol injection — mimics volcanic eruptions (e.g., Mt. Pinatubo 1991 cooled Earth by 0.5°C); sulphate particles reflect incoming sunlight back to space.

Both are CONTROVERSIAL geoengineering proposals — scientifically debated; concerns about unintended consequences, governance.

• (a) Artificial rain — cloud seeding (silver iodide etc.), different tech.
• (b) Cyclone intensity reduction — different framework.
• (c) Solar wind effects — magnetosphere phenomena, different.

Answer (d): Waste-to-energy technologies. PYROLYSIS (thermal decomposition of organic matter in absence of oxygen, producing gas, liquid, and solid products) and PLASMA GASIFICATION (ultra-high-temperature plasma arc converting waste into syngas and slag) are both WASTE-TO-ENERGY (WtE) TECHNOLOGIES for MUNICIPAL SOLID WASTE (MSW) disposal. They produce energy (syngas, heat, electricity) while reducing waste volume.

• (a) Rare earth extraction — uses different processes (hydrometallurgy).
• (b) Natural gas extraction — uses drilling/fracking, not pyrolysis.
• (c) Hydrogen fuel cars — uses electrolysis or steam-methane reforming.

Answer (a): Neyyar, Peppara and Shendurney Wildlife Sanctuaries; and Kalakad Mundanthurai Tiger Reserve. The AGASTHYAMALA BIOSPHERE RESERVE (declared 2001, added to UNESCO MAB network 2016) is in the SOUTHERN WESTERN GHATS spanning KERALA and TAMIL NADU. It includes:

• NEYYAR WILDLIFE SANCTUARY (Kerala) ✓
• PEPPARA WILDLIFE SANCTUARY (Kerala) ✓
• SHENDURNEY WILDLIFE SANCTUARY (Kerala) ✓
• KALAKAD MUNDANTHURAI TIGER RESERVE (Tamil Nadu) ✓
• (b) Mudumalai, Sathyamangalam, Wayanad WLS + Silent Valley NP = Nilgiri Biosphere Reserve, not Agasthyamala.
• (c) Kaundinya, Gundla Brahmeswaram, Papikonda + Mukurthi NP = part of other Eastern Ghats / Nilgiri setups.
• (d) Kawal, Sri Venkateswara WLS + Nagarjunasagar-Srisailam TR = Andhra Pradesh Eastern Ghats.

Answer (d): 1, 2, 3 and 4.

• 1. Herbivorous turtles ✓ — Many turtle species are herbivorous (green sea turtle eats sea grass and algae; most tortoises are primarily herbivorous).
• 2. Herbivorous fish ✓ — Many fish are herbivores (parrotfish, surgeonfish, grass carp eat algae/plants).
• 3. Herbivorous marine mammals ✓ — DUGONGS AND MANATEES (Sirenia) are exclusively HERBIVOROUS marine mammals, eating seagrasses.
• 4. Viviparous snakes ✓ — Some snakes are VIVIPAROUS (give birth to live young) — e.g., sea snakes, boas, vipers. Not all snakes are oviparous.

Answer (c): 1 and 3 only. Wildlife — habitat pairs:

• 1. BLUE-FINNED MAHSEER — CAUVERY RIVER ✓ — The Blue-finned Mahseer (Tor khudree) is native to the Cauvery River basin (Karnataka, Tamil Nadu), critically endangered ✓.
• 2. IRRAWADDY DOLPHIN — CHAMBAL RIVER ✗ — The Irrawaddy Dolphin (Orcaella brevirostris) in India is found in CHILIKA LAKE (Odisha) and parts of the Sundarbans/Ganges delta — NOT the Chambal. Chambal has the GANGETIC DOLPHIN (Platanista gangetica) — classic dolphin-habitat swap.
• 3. RUSTY-SPOTTED CAT — EASTERN GHATS ✓ — The Rusty-spotted Cat (Prionailurus rubiginosus), the world's smallest wild cat, is found in Eastern Ghats, parts of Central India, and Sri Lanka ✓.

Answer (a): They are considered harmful to marine ecosystems. MICROBEADS are TINY PLASTIC PARTICLES (typically 0.1-5 mm, made of polyethylene, polypropylene, polystyrene) used as EXFOLIANTS in cosmetics (face scrubs, toothpaste, body wash) and other personal-care products. Because they are NOT BIODEGRADABLE and are too small to be filtered by wastewater treatment plants, they FLOW INTO RIVERS AND OCEANS where they CAUSE SIGNIFICANT HARM TO MARINE ECOSYSTEMS (ingested by fish and zooplankton, accumulate in food chain, bioaccumulate toxic substances). Many countries (USA, UK, Canada, India) have banned/phased out microbeads in cosmetics.

• (b) Skin cancer in children — not a direct established link.
• (c) Plant absorption in fields — not the primary concern.
• (d) Food adulterants — not the usage context.

Answer (d): Vijayanagara. The KALYANA MANDAPA (literally 'marriage hall/pavilion') is a DISTINCTIVE FEATURE of VIJAYANAGARA TEMPLE ARCHITECTURE (c. 1336-1646). These are ELABORATE OPEN PILLARED HALLS within temple complexes, often featuring HORSE PILLARS / YALI PILLARS and used for DIVINE MARRIAGE CEREMONIES (Utsava Murtis). Examples: Vitthala Temple (Hampi), Varadaraja Temple (Kanchipuram), Meenakshi Temple complex (Madurai) — though the feature was pioneered and elaborated under Vijayanagara patronage, especially by Krishnadevaraya.

• (a) Chalukya — different architectural style (Aihole, Badami).
• (b) Chandela — Khajuraho style, different features.
• (c) Rashtrakuta — Ellora/Kailasa, different.

Answer (a): 1 only. Delhi Sultanate revenue administration:

• S1 CORRECT — The in-charge of revenue collection in the Delhi Sultanate was known as 'AMIL' (the revenue collector at the local/pargana level) ✓.
• S2 WRONG — The IQTA SYSTEM of the Delhi Sultans was NOT an ancient indigenous institution. It was a PERSO-ARABIC/ISLAMIC INSTITUTION (origin in the Abbasid Caliphate, adapted from the Seljuk-Ghurid system), introduced to India by the early Sultans of Delhi. Iqta = assignment of revenue from a territory in lieu of salary. Classic 'indigenous vs imported' swap.
• S3 WRONG — The office of 'MIR BAKSHI' (imperial paymaster / head of military administration) came into existence under the MUGHALS (particularly Akbar's reign), NOT the Khalji Sultans. Classic dynasty attribution swap.

Answer (d): Neither 1 nor 2.

• S1 WRONG — Saint NIMBARKA lived in the 12TH-13TH CENTURY (c. 1130-1200 CE) — founder of the Dvaitadvaita (Nimbarka Sampradaya) school. AKBAR ruled 1556-1605. So Nimbarka was NOT A CONTEMPORARY of Akbar — separated by ~400 years. Classic chronology error.
• S2 WRONG — Saint KABIR lived c. 1440-1518 CE. SHAIKH AHMAD SIRHINDI (the Naqshbandi Sufi reformer) lived 1564-1624 CE — AFTER Kabir. So Kabir could NOT have been influenced by Sirhindi (who came later). Chronology is inverted.

Answer (b): 1 and 3 only.

• S1 CORRECT — MAHATMA GANDHI WAS INSTRUMENTAL in the ABOLITION OF THE SYSTEM OF 'INDENTURED LABOUR' — from his South Africa years and through the agitation after his return to India, culminating in the formal abolition by the British in 1920 (though planning began 1916) ✓.
• S2 WRONG — At LORD CHELMSFORD'S WAR CONFERENCE (Delhi, April 1918), MAHATMA GANDHI DID SUPPORT THE RESOLUTION on recruiting Indians for World War I — at that time, Gandhi believed cooperation with the British war effort would earn Dominion status for India post-war. He did NOT oppose the resolution (controversial decision). S2 inverts Gandhi's actual position.
• S3 CORRECT — Following the BREAKING OF THE SALT LAW at Dandi (6 April 1930) and the Civil Disobedience Movement, the colonial government DECLARED THE INDIAN NATIONAL CONGRESS ILLEGAL (January 1932, Emergency Powers Ordinances) ✓.

Answer (d): 1, 2, and 3. Person — Position pairings:

• 1. SIR TEJ BAHADUR SAPRU — PRESIDENT, ALL INDIA LIBERAL FEDERATION ✓ — Sapru was a prominent moderate-liberal and served as President of the All India Liberal Federation (the political platform of the Liberal Party of India, successor to the Moderates after 1919) ✓.
• 2. K.C. NEOGY — MEMBER, CONSTITUENT ASSEMBLY ✓ — Kshitish Chandra Neogy was a Member of the Constituent Assembly from West Bengal; later served as the first Chairman of the Finance Commission (1951) ✓.
• 3. P.C. JOSHI — GENERAL SECRETARY, COMMUNIST PARTY OF INDIA ✓ — Puran Chand Joshi served as General Secretary of the CPI (1935-1947), a key figure in Indian Communist politics ✓.

All three pairings are correctly matched.

Answer (a): Tansen was the title given to him by Emperor Akbar. (The INCORRECT statement — Q asks which is NOT correct.)

• (a) WRONG ✓ — Tansen's BIRTH NAME was RAMTANU PANDEY (also Tanna Mishra); he received the TITLE 'MIYA' ('MIAN TANSEN') from EMPEROR AKBAR, NOT 'Tansen' itself. 'Tansen' was likely an earlier title from Raja Vikramjit of Gwalior / Raja Ramchandra of Rewa. 'Miyan' (Mian Tansen, Mian Tansen) is the title Akbar conferred — for mastery of ragas.
• (b) CORRECT — Tansen COMPOSED DHRUPADS on Hindu gods and goddesses (many dhrupads on Lord Shiva, Rama, Krishna, Durga — despite being in Akbar's court) ✓.
• (c) CORRECT — Tansen COMPOSED SONGS ON HIS PATRONS (Akbar, earlier Raja Ramchandra of Rewa) ✓.
• (d) CORRECT — Tansen INVENTED/CONTRIBUTED to MANY RAGAS — Miyan ki Malhar, Miyan ki Todi, Darbari Kanada, etc. ✓.

Answer (c): Jahangir. EMPEROR JAHANGIR (1605-1627) is known for the MAJOR STYLISTIC SHIFT in Mughal painting FROM ILLUSTRATED MANUSCRIPTS (which dominated Akbar's era — Akbarnama, Baburnama, Hamzanama, etc.) TO ALBUM (MURAQQA) AND INDIVIDUAL PORTRAITS (single-sheet paintings mounted in albums, portraits of courtiers and notables, animal/bird studies). Jahangir was a connoisseur of naturalistic portraiture — Ustad Mansur, Abu al-Hasan, Bishandas were celebrated court painters. This era saw European influence (Tuzuk-i-Jahangiri records his interest in Flemish painting).

• (a) Humayun — brought Persian painters Mir Sayyid Ali, Abd al-Samad to India, but no portrait-focus shift.
• (b) Akbar — illustrated manuscripts era (Akbarnama).
• (d) Shah Jahan — continued album tradition, but the portrait-shift originated with Jahangir.

Answer (d): Valley of Flowers National Park. VALLEY OF FLOWERS NATIONAL PARK (Uttarakhand, Chamoli district, Bhyundar Valley) LIES COMPLETELY IN THE TEMPERATE-ALPINE ZONE (ALTITUDE ~3,200-6,675 m). A UNESCO World Heritage Site, renowned for endemic alpine flora (blue poppies, brahmakamal, cobra lily). Forms part of Nanda Devi Biosphere Reserve.

• (a) Manas NP (Assam) — lies in tropical-subtropical foothills of Bhutan Himalaya, NOT completely temperate-alpine.
• (b) Namdapha NP (Arunachal Pradesh) — spans tropical to alpine (altitudinal range 200-4,571 m) — NOT completely temperate-alpine.
• (c) Neora Valley NP (West Bengal) — subtropical to temperate, NOT fully temperate-alpine.

Answer (c): NITI Aayog. THE ATAL INNOVATION MISSION (AIM) IS A FLAGSHIP INITIATIVE SET UP UNDER NITI AAYOG (2016) to promote INNOVATION AND ENTREPRENEURSHIP across India. Key components:

• ATAL TINKERING LABS (ATLs) in schools (maker spaces, DIY kits).
• ATAL INCUBATION CENTRES (AICs) in universities/research institutions.
• ATAL NEW INDIA CHALLENGES (ANIC) — problem-solving grants.
• Atal Grand Challenges — social-impact innovation.

Named after Atal Bihari Vajpayee; serves as the central 'innovation mission' platform.

• (a) DST — funds science/tech but not AIM.
• (b) Labour/Employment — unrelated.
• (d) Skill Development Ministry — hosts PMKVY, not AIM.

Answer (a): Does not set below the horizon at the Arctic Circle. ON 21 JUNE (SUMMER SOLSTICE, in Northern Hemisphere):

• (a) CORRECT — At the ARCTIC CIRCLE (66.5°N), the SUN DOES NOT SET below the horizon — it remains visible for 24 hours (Midnight Sun phenomenon). This is the POLAR DAY ✓.
• (b) WRONG — At the ANTARCTIC CIRCLE (66.5°S), on 21 June (Southern winter), the sun does NOT RISE above the horizon — it's POLAR NIGHT. So the sun DOES set (below horizon, continuously) — opposite of (b).
• (c) WRONG — On 21 June, the sun is vertically overhead at the TROPIC OF CANCER (23.5°N), NOT the Equator. Equator has equal day/night only on equinoxes (21 March, 22 September).
• (d) WRONG — Tropic of Capricorn (23.5°S) has vertical sun on 22 December, NOT 21 June.

Answer (d): 1, 2 and 3. All three activities release REACTIVE NITROGEN COMPOUNDS into the environment:

• 1. AGRICULTURAL SOILS release NITROGEN OXIDES (N2O especially, a potent greenhouse gas) — from fertilizer application and microbial nitrification/denitrification ✓.
• 2. CATTLE (and other livestock) release AMMONIA (NH3) — from urine/manure volatilization — a major agricultural air pollutant ✓.
• 3. POULTRY INDUSTRY releases REACTIVE NITROGEN COMPOUNDS (ammonia, nitrous oxide) — from chicken manure, intensive production systems ✓.

All three contribute to the 'nitrogen cascade' — anthropogenic disruption of the nitrogen cycle.

Answer (d): Water reservoirs. ALIYAR, ISAPUR, and KANGSABATI are all NAMES OF WATER RESERVOIRS / DAM PROJECTS in India:

• ALIYAR Reservoir / Aliyar Dam — in Coimbatore district, TAMIL NADU, on Aliyar River (part of Parambikulam-Aliyar Project).
• ISAPUR Dam — in Yavatmal district, MAHARASHTRA, on Penganga River.
• KANGSABATI Reservoir / Mukutmanipur Dam — in Bankura district, WEST BENGAL, on Kangsabati River (India's 2nd-largest earthen dam).

All three are WATER RESERVOIRS/DAMS.

• (a) Uranium — no.
• (b) Tropical rainforests — no.
• (c) Cave systems — no.

Answer (b): 2 and 3 only. H-CNG (Hydrogen-enriched CNG) as bus fuel in India (Delhi pilot 2019-20):

• S1 WRONG — H-CNG REDUCES but does NOT ELIMINATE CO (carbon monoxide) emissions. Hydrogen enrichment improves combustion efficiency, cutting CO/HC, but CO emissions remain non-zero. 'Elimination' is an overclaim.
• S2 CORRECT — H-CNG reduces CARBON DIOXIDE AND HYDROCARBON (HC) emissions due to better combustion characteristics ✓.
• S3 CORRECT — Up to ~18% HYDROGEN BY VOLUME can be blended with CNG (per Indian Oil's patented compact reformer technology used in Delhi pilot; ~1/5 by volume) ✓.
• S4 WRONG — H-CNG is more EXPENSIVE than CNG (hydrogen production cost is high), NOT less expensive. Classic cost-direction inversion.

Answer (b): Clouds reflect back the Earth's radiation. DEW forms when the Earth's surface COOLS OVERNIGHT below the DEW POINT (water vapour condenses on surfaces). On a CLOUDY NIGHT, DEW DOES NOT FORM because CLOUDS REFLECT BACK (re-radiate/absorb and re-emit) the LONG-WAVE INFRARED RADIATION EMITTED BY THE EARTH'S SURFACE. This 'greenhouse-like' trapping keeps the surface relatively WARMER, preventing it from cooling below the dew point.

• (a) Clouds absorb radiation — partial truth but the key mechanism is the reflection/back-radiation that keeps surface warm.
• (c) Low temperature on cloudy nights — opposite of reality; cloudy nights are warmer.
• (d) Clouds deflecting wind — unrelated to dew formation.

Answer (b): 2 only.

• S1 WRONG — The 44th Amendment Act, 1978 did NOT introduce an article placing the ELECTION OF THE PRIME MINISTER beyond judicial review. The 39th Amendment Act, 1975 (during Emergency) had placed the PM's election beyond judicial review (to protect Indira Gandhi's election), but this was STRUCK DOWN by the Supreme Court in Indira Gandhi v. Raj Narain (1975) AND REPEALED by the 44th Amendment (1978) — which RESTORED judicial review. So the 44th Amendment did the OPPOSITE. S1 inverts the fact.
• S2 CORRECT — The Supreme Court DID STRIKE DOWN the 99TH AMENDMENT (2014, establishing NJAC) as VIOLATIVE of the INDEPENDENCE OF JUDICIARY (basic structure) in the NJAC case (2015) ✓.

Answer (c): 3 and 4 only.

• S1 WRONG — The MOTION to IMPEACH a Judge CAN BE REJECTED by the SPEAKER of Lok Sabha under the Judges (Inquiry) Act, 1968 — the Speaker/Chairman has discretion to admit/reject the motion after consulting such persons. The claim that it 'cannot be rejected' is factually wrong.
• S2 WRONG — The CONSTITUTION DOES NOT DEFINE OR GIVE DETAILS of what constitutes 'INCAPACITY AND PROVED MISBEHAVIOUR'. These terms are broadly mentioned in Art 124(4) but their substantive content is left to practice and judicial interpretation — NOT defined in the Constitution. (Per PDF: Constitution rarely defines things in detail.)
• S3 CORRECT — The details of the IMPEACHMENT PROCESS (inquiry committee, conduct of inquiry, report) are in the JUDGES (INQUIRY) ACT, 1968 ✓.
• S4 CORRECT — Each House must pass the motion by a MAJORITY OF TOTAL MEMBERSHIP and not less than TWO-THIRDS OF MEMBERS PRESENT AND VOTING (Art 124(4) + Art 124(5)) ✓.

Answer (a): Jawaharlal Nehru. The NINTH SCHEDULE was INTRODUCED in the Constitution of India by the FIRST CONSTITUTION AMENDMENT ACT, 1951 — during the PRIME MINISTERSHIP OF JAWAHARLAL NEHRU (PM 1947-1964). The Schedule was inserted along with Article 31B to protect LAND REFORM LAWS (zamindari abolition, land ceilings) from being struck down as violating the fundamental right to property (then under Art 19 and Art 31). Only 13 laws initially; now over 280 laws.

• (b) Shastri (1964-66) — no such introduction.
• (c) Indira Gandhi (1966-77, 1980-84) — did place many more laws under 9th Schedule, but didn't introduce it.
• (d) Morarji Desai (1977-79) — no Ninth Schedule additions.

Answer (a): 1 only.

• S1 CORRECT — COAL SECTOR WAS NATIONALIZED under INDIRA GANDHI's government via the Coking Coal Mines (Nationalisation) Act 1972 and Coal Mines (Nationalisation) Act 1973 — all coal mining became a PSU monopoly (Coal India Ltd formed 1975) ✓.
• S2 WRONG — Coal blocks are NOT ALLOCATED ON LOTTERY BASIS. Post-Supreme Court 2014 judgment (coal scam cancellations), blocks have been allocated via COMPETITIVE AUCTION (Coal Mines (Special Provisions) Act 2015). Lottery is not the method.
• S3 WRONG — INDIA STILL IMPORTS COAL (coking coal for steel plants + some thermal coal for specific quality needs, especially Indonesian sub-bituminous for coastal plants). India is NOT self-sufficient — ~200+ million tonnes coal imported annually. Claim is factually wrong.

Answer (a): 1 and 2 only.

• S1 CORRECT — The PARLIAMENT (PREVENTION OF DISQUALIFICATION) ACT, 1959 EXEMPTS SEVERAL POSTS from disqualification under Article 102(1)(a) / 191(1)(a) (Office of Profit disqualification). Posts like certain ministerial portfolios, parliamentary secretaries, etc. are statutorily exempted ✓.
• S2 CORRECT — The 1959 Act has been AMENDED MULTIPLE TIMES — adding/removing exempted posts (including the 2006 retrospective amendment covering positions like Sonia Gandhi's then-held NAC chairperson post). Multiple amendments is accurate ✓.
• S3 WRONG — The TERM 'OFFICE OF PROFIT' is NOT DEFINED IN THE CONSTITUTION. It is a judicial construct interpreted by the Supreme Court through various cases (Ravanna Subanna v. Kage, Pradyut Bordoloi v. Swapan Roy, Jaya Bachchan v. UoI, etc.). Per the PDF's Constitution-rarely-defines principle, S3 fails.

Answer (b): Fifth Schedule. Under the FIFTH SCHEDULE of the Constitution of India (applicable to SCHEDULED AREAS of states other than the NE states), the TRANSFER OF TRIBAL LAND TO NON-TRIBALS/PRIVATE PARTIES for MINING OR OTHER PURPOSES CAN BE DECLARED NULL AND VOID. Key case: SAMATHA v. STATE OF ANDHRA PRADESH (1997) where the SC held that mining leases to non-tribal private parties in Scheduled Areas violated the Fifth Schedule. The SC struck down such leases.

• (a) Third Schedule — oaths/affirmations, unrelated.
• (c) Ninth Schedule — saves laws from judicial review (land reform etc.).
• (d) Twelfth Schedule — 74th Amendment municipal functions.

Answer (d): textile fibre. The HIMALAYAN NETTLE (Girardinia diversifolia, also known as 'Allo' in Nepali, 'Bichhu booti' in local languages) is increasingly recognised as a SUSTAINABLE SOURCE of NATURAL TEXTILE FIBRE. Traditionally used by Himalayan communities (Uttarakhand, Nepal, Bhutan), the bark fibre is extracted, processed, and woven into fabrics ('allo cloth'). The fibre is biodegradable, strong, lustrous, making it attractive for eco-textile markets. Supported by WWF and government/NGO livelihood initiatives.

• (a) Anti-malarial drug — that's quinine (from cinchona) or artemisinin (from Artemisia annua).
• (b) Biodiesel — not a nettle-based source.
• (c) Pulp for paper — not its primary use.

Answer (d): 1, 2 and 3. Satellite imagery / remote sensing applications:

• 1. CHLOROPHYLL CONTENT in vegetation ✓ — Measured via VEGETATION INDICES (NDVI — Normalized Difference Vegetation Index) computed from red and near-infrared bands. Standard remote-sensing parameter.
• 2. GREENHOUSE GAS EMISSIONS from rice paddies ✓ — Satellites (e.g., GOSAT, OCO-2/3) can estimate METHANE AND CO2 emissions from specific locations — including agricultural sources like rice paddies — via spectral absorption in short-wave infrared.
• 3. LAND SURFACE TEMPERATURES ✓ — Thermal infrared sensors (Landsat TIRS, MODIS thermal bands, Aqua/Terra) routinely measure land surface temperatures, used in urban heat island studies, drought monitoring, etc.

Answer (c): 3-2-4-1. Forest cover as % of state area (approx., per ISFR 2017/2019):

• 3. MAHARASHTRA — ~16.5% forest cover (lowest of the four)
• 2. MADHYA PRADESH — ~25.1% forest cover
• 4. ODISHA — ~33.2% forest cover
• 1. CHHATTISGARH — ~41.1% forest cover (highest of the four)

Ascending order (lowest to highest): Maharashtra → MP → Odisha → Chhattisgarh = 3-2-4-1.

• (a) 2-3-1-4 — Wrong order.
• (b) 2-3-4-1 — Wrong order.
• (c) 3-2-4-1 ✓ — Correct ascending order.
• (d) 3-2-1-4 — Wrong order (Chhattisgarh highest, not Odisha).

Answer (d): 1, 2 and 3. Methane hydrate:

• S1 CORRECT — GLOBAL WARMING MIGHT TRIGGER THE RELEASE of METHANE GAS from methane hydrate deposits — as warming ocean and permafrost destabilise the hydrate lattice, releasing CH4 (a potent GHG), creating a POSITIVE FEEDBACK LOOP (clathrate gun hypothesis) ✓.
• S2 CORRECT — Large deposits of METHANE HYDRATE are found in ARCTIC TUNDRA (permafrost) AND UNDER THE SEAFLOOR (continental margins, deep ocean cold-pressurised environments) ✓.
• S3 CORRECT — METHANE in the atmosphere OXIDIZES to CARBON DIOXIDE AFTER ROUGHLY A DECADE OR TWO (methane's atmospheric lifetime is ~12 years, after which it's converted via OH radicals into CO2) ✓.

Answer (d): 1, 2, 3 and 4. BURNING OF CROP/BIOMASS RESIDUE (e.g., stubble burning in Punjab-Haryana post-paddy harvest) releases ALL of the listed pollutants:

• 1. CARBON MONOXIDE (CO) ✓ — Incomplete combustion product, major urban/regional air quality concern.
• 2. METHANE (CH4) ✓ — Incomplete combustion / smouldering releases methane, a potent GHG.
• 3. OZONE (O3) ✓ — Formed PHOTOCHEMICALLY from NOx and VOCs (both released by biomass burning) in presence of sunlight — a secondary pollutant from biomass burning plumes.
• 4. SULPHUR DIOXIDE (SO2) ✓ — Biomass contains some sulphur; burning releases SO2 (typically small amounts but measurable).

All four are released.

Answer (b): 1, 3 and 4 only. Sea-Bordering Country pairs:

• 1. ADRIATIC SEA — ALBANIA ✓ — Albania has a coast on the Adriatic Sea (western Albania) ✓.
• 2. BLACK SEA — CROATIA ✗ — Black Sea borders Turkey, Bulgaria, Romania, Ukraine, Russia, Georgia — NOT Croatia (which is on the ADRIATIC SEA). Classic country-swap.
• 3. CASPIAN SEA — KAZAKHSTAN ✓ — Kazakhstan has a long Caspian Sea coast (western Kazakhstan) ✓.
• 4. MEDITERRANEAN SEA — MOROCCO ✓ — Morocco has a Mediterranean coast in the north (Tangier, Tetouan area) ✓.
• 5. RED SEA — SYRIA ✗ — Syria is on the MEDITERRANEAN SEA (Latakia, Tartous), NOT the Red Sea. Red Sea borders Saudi Arabia, Yemen, Egypt, Sudan, Eritrea, Djibouti. Classic sea-swap.

Answer (b): India. Among the listed options, INDIA has been the LARGEST EXPORTER OF RICE IN THE WORLD in the last 5 years (as of 2018-19 and beyond) — exporting ~12-15 million tonnes annually (basmati and non-basmati combined). Key destinations: Bangladesh, Nepal, Iran, Saudi Arabia, Benin, etc.

• (a) China — world's LARGEST PRODUCER and LARGEST CONSUMER of rice, but it's a NET IMPORTER — not a top exporter.
• (c) Myanmar — exports ~2-3 million tonnes, less than India.
• (d) Vietnam — second-largest global rice exporter (~6-7 million tonnes) but less than India.

Answer (a): 1, 2 and 4. Glacier — River source pairs:

• 1. BANDARPUNCH — YAMUNA ✓ — The Bandarpunch Glacier (Uttarakhand) is one of the sources of the YAMUNA River ✓.
• 2. BARA SHIGRI — CHENAB ✓ — The Bara Shigri Glacier (Himachal Pradesh, Lahaul-Spiti) feeds the CHANDRA river, a source of the CHENAB (Chandra + Bhaga = Chandrabhaga = Chenab) ✓.
• 3. MILAM — MANDAKINI ✗ — The Milam Glacier (Uttarakhand, Pithoragarh district) is the source of the GORIGANGA river (tributary of Kali/Sharda) — NOT the Mandakini (which originates from Chorabari Glacier near Kedarnath). Classic glacier-river swap.
• 4. SIACHEN — NUBRA ✓ — The Siachen Glacier (Ladakh) is the source of the NUBRA river (tributary of Shyok) ✓.
• 5. ZEMU — Manao ✗ — The Zemu Glacier (Sikkim, eastern Himalaya) is the source of the TEESTA river (via the Zemu Chhu), NOT 'Manao' (which isn't a standard river name).

Answer (a): Pesticides in agriculture. CARBOFURAN, METHYL PARATHION, PHORATE, and TRIAZOPHOS are all SYSTEMIC/CONTACT PESTICIDES (organophosphates and carbamates) USED IN AGRICULTURE:

• CARBOFURAN — carbamate insecticide (banned/restricted in many countries due to toxicity to birds).
• METHYL PARATHION — organophosphate insecticide (highly toxic; India restricted for many crops).
• PHORATE — organophosphate systemic insecticide.
• TRIAZOPHOS — organophosphate insecticide.

All are VIEWED WITH APPREHENSION due to acute toxicity (including human poisoning, pollinator decline, bioaccumulation).

• (b) Food preservatives — no.
• (c) Fruit-ripening — that's ethylene/acetylene/ethephon.
• (d) Cosmetic moisturisers — no.

Answer (c): 3 only.

• S1 WRONG — Under the RAMSAR CONVENTION (1971), signatories UNDERTAKE TO CONSERVE and WISELY USE their DESIGNATED RAMSAR SITES — NOT 'all wetlands in the territory of India'. There are only ~75+ Ramsar Sites in India (of thousands of wetlands); obligations relate specifically to designated sites, not every wetland. S1 overclaims.
• S2 WRONG — The WETLANDS (CONSERVATION AND MANAGEMENT) RULES, 2010 were framed under the ENVIRONMENT PROTECTION ACT 1986 (domestic law), with reference to Ramsar and constitutional duties. They weren't 'based on Ramsar Convention recommendations' per se — Ramsar doesn't issue binding recommendations. Misattribution.
• S3 CORRECT — The WETLANDS (CONSERVATION AND MANAGEMENT) RULES, 2010 DO ENCOMPASS the DRAINAGE AREA OR CATCHMENT REGIONS of the wetlands — ecosystem-approach framing ✓. (Note: 2017 rules revised this further.)
