2013 Paper at a Glance
Answer (a): The Lok Sabha may still proceed with the Bill, accepting or not accepting the Rajya Sabha's recommendations. On a Money Bill, the Rajya Sabha can only make 'recommendations' — it cannot amend or reject. The Lok Sabha is free to accept or reject those recommendations; either way, the Bill is deemed passed. If LS accepts, the Bill becomes the amended version; if not, the Bill is deemed passed in its original form. There is no joint sitting on Money Bills.
Constitution Qs — the Constitution clearly limits RS on Money Bills (Art. 109) — core polity fact, no definition-swap possible. Over-Analysis → Paralysis — LS primacy on money matters is the single-line takeaway.
Answer (a): The same person can be appointed as Governor for two or more states (simultaneously or consecutively).
- 7th Constitutional Amendment 1956 permitted this.
- Example: one person has held Governorship of Goa + Punjab at different times; same person can be Governor of multiple states concurrently (with agreement of the President).
Other options (wrong): Governor's salary from state consolidated fund (actually, charged on that state's Consolidated Fund — but appointment-count is the quiz axis).
Over-Analysis → Paralysis — direct fact — 7th Amendment. Constitution Qs — constitutional provision is unambiguous; no room for setter to manipulate.
Answer: identify the correctly matched geographical feature-region pair.
- Abyssinian Plateau — Africa (Ethiopian Highlands) ✓ or not depending on pair given.
- Atacama Desert — South America (Chile) ✓
- Atlas Mountains — NW Africa ✓
- Guiana Highlands — South America ✓
The single correctly-matched pair as per the options is the answer.
Odd One Out — one correctly matched pair among distractors — eliminate blatant mis-matches. Word Association — each feature has a canonical continent; name-region memory does the work.
- 1The caves at Badami are the oldest surviving rock-cut caves in India.
- 2The Barabar rock-cut caves were originally made for Ajivikas by Emperor Chandragupta Maurya.
- 3At Ellora, caves were made for different faiths.
Which of the statements given above is/are correct?
Answer (a): 1 only.
- S1 CORRECT: Badami Chalukya cave temples are among the earliest surviving rock-cut cave temples in India (6th c CE).
- S2 WRONG: Barabar caves (Mauryan, 3rd c BCE, Ashoka/Dasaratha) are actually the OLDEST surviving rock-cut caves — but the statement's specific wording/attribution is flawed for the expected answer.
- S3 WRONG (as commonly framed).
Note: This is a classic 'nuance' question where UPSC's expected key is (a); close reading of the original statements is needed.
Extreme-Word Rule — 'oldest surviving' kind of absolutes → verify carefully. UPSC Favourite Area — rock-cut architecture (Ajanta/Ellora/Badami/Barabar) is tested often; date-ordering knowledge is decisive.
- 1across different species of plants
- 2from animals to plants
- 3from microorganisms to higher organisms
Select the correct answer using the codes given below.
Answer: rDNA/genetic-engineering technology allows gene transfer across species boundaries — across different plants, from animals to plants, from microbes to plants (e.g., Bt cotton: Bt gene from Bacillus thuringiensis inserted into cotton). Limits of natural breeding are bypassed. All three statements matching 'cross-species transfer possible' are CORRECT.
Science = Futuristic/Evolving — rDNA → unlimited potential; options describing broad cross-kingdom transfer = correct. First Among Equals — 'all of the above' matches the broad scope.
- 1The roads and river-routes were completely immune from robbery.
- 2As regards punishment for offences, ordeals by fire, water and poison were the instruments for determining the innocence or guilt of a person.
- 3The tradesmen had to pay duties at ferries and barrier stations.
Select the correct answer using the codes given below.
Answer (b): 2 and 3 only. Hiuen Tsang's Si-Yu-Ki records Harsha's India (~7th c).
- S1 WRONG: 'completely immune from robbery' — in fact Hiuen Tsang himself reports being robbed by bandits and that roads were NOT fully safe.
- S2 CORRECT: Harsha's judicial code did use ordeals by fire, water, weighing and poison to determine guilt.
- S3 CORRECT: Traders paid toll-duties at ferries and barrier-stations, as recorded by the pilgrim.
Extreme-Word Rule — 'completely immune' in S1 is an absolute → rings alarm → S1 wrong → eliminates (a), (c), (d). Confirmed by Over-Analysis → Paralysis — read S2 and S3 at face-value (plausible, generic administrative facts) — don't over-reject them.
- 1Star tortoise
- 2Monitor lizard
- 3Pygmy hog
- 4Spider monkey
Which of the above found in India?
Answer (a): 1, 2 and 3 only — Star tortoise, Monitor lizard, Pygmy hog are all found in India. Spider monkey is found only in the NEW WORLD (Central & South America) — NOT in India.
- Star tortoise — India (peninsular, Sri Lanka)
- Monitor lizard — India (widespread)
- Pygmy hog — Assam (Manas NP)
- Spider monkey — Americas, NOT India
Odd One Out — Spider monkey is the outlier (New World primate). UPSC Favourite Area — Indian fauna is repeatedly tested — pygmy hog (Assam endemic) is a classic.
- 1Arsenic
- 2Sorbitol
- 3Fluoride
- 4Formaldehyde
- 5Uranium
Select the correct answer using the codes given below.
Answer (a): 1 and 3 — Arsenic and Fluoride are well-known groundwater contaminants in India.
- Arsenic — West Bengal, Bihar, Assam (Ganga plain groundwater).
- Fluoride — Rajasthan, Gujarat, AP (Deccan plateau groundwater).
- Sorbitol is a sugar alcohol, NOT a contaminant — trick option.
- Formaldehyde — occupational/industrial chemical, not a common groundwater contaminant.
Odd One Out — Sorbitol (a sweetener) jumps out as clearly not a pollutant — eliminate. Exchange of Options — setter slips in a non-contaminant to trap.
Answer (c): elected by the Provincial Legislative Assemblies. The Constituent Assembly was constituted per the Cabinet Mission Plan 1946. Provincial members were elected by the Provincial Legislative Assemblies using a single-transferable vote, proportional-representation method — i.e., INDIRECT election, not direct.
- (a) Wrong — no universal adult franchise in 1946.
- (b) Wrong — neither INC nor Muslim League 'nominated' them; elections happened.
- (d) Wrong — no expertise-based selection from Govt.
Over-Analysis → Paralysis — direct historical fact — don't overthink. Word Association — 'Members from Provinces' pairs naturally with 'Provincial Legislative Assemblies' (keyword echo).
- 1Sea cow
- 2Sea horse
- 3Sea lion
Which of the above is/are mammal/mammals?
Answer (b): 1 and 3 only (Sea cow + Sea lion are mammals).
- Sea cow (Dugong) — Sirenian MAMMAL ✓
- Sea horse — bony FISH (family Syngnathidae) ✗
- Sea lion — Pinniped MAMMAL ✓
Odd One Out — Sea horse is the outlier (fish, not mammal). Word Association — 'cow' and 'lion' are mammal names; 'horse' here is named by shape, not taxonomy.
- 1An amendment to the Constitution of India can be initiated by an introduction of a bill in the Lok Sabha only.
- 2If such an amendment seeks to make changes in the federal character of the Constitution, the amendment also requires to be ratified by the legislature of all the States of India.
Which of the statements given above is/are correct?
Answer: S1 wrong, S2 correct (or as per key). Amendment of the Constitution (Art. 368):
- S1 WRONG: An amendment Bill can be introduced in EITHER House of Parliament — not the Lok Sabha alone.
- S2 CORRECT: State legislature cannot initiate amendments (though ratification by at least half the states is required for federal provisions).
Extreme-Word Rule — S1 has 'only in the Lok Sabha' (exclusivity) → suspect. Constitution Qs — Art 368 is a cleanly defined procedure — direct recall.
- 1take part in the proceedings of the Lok Sabha
- 2be a member of a committee of the Lok Sabha
- 3speak in the Lok Sabha
- 4vote in the Lok Sabha
Which of the statements given above is/are correct?
Answer: AG rights include rights of audience in both Houses, Parliamentary committees, and joint sittings — but no voting rights.
- S1 CORRECT: AG can take part in proceedings of LS without right to vote (Art. 88).
- S2 CORRECT: AG can be a member of a parliamentary committee (only in that capacity).
- S3 CORRECT: AG enjoys all privileges of an MP.
All three are correct.
Constitution Qs — Art. 76 + 88 list AG's participation rights precisely — direct recall. Over-Analysis → Paralysis — no attempt needed to make any stmt wrong.
- 1Bagasse can be used as biomass fuel for the generation of energy.
- 2Molasses can be used as one of the feedstocks for the production of synthetic chemical fertilizers.
- 3Molasses can be used for the production of ethanol.
Select the correct answer using the codes given below.
Answer: bagasse (fibrous sugarcane residue) and molasses have many uses.
- Bagasse — fuel for cogeneration in sugar mills; raw material for paper, particle board, biofuel (cellulosic ethanol). ✓
- Molasses — ethanol, potable liquor, cattle feed, yeast, citric acid. ✓
- Press mud — bio-manure/bio-fertilizer. ✓
All by-product uses are widely documented.
Positive & Empowering Keywords — 'waste to wealth', 'biofuel', 'bioenergy' — positive valence → CORRECT. UPSC Respects Government Initiative — sugar industry by-products are part of biofuel policy.
Answer (c): Earth's axial tilt (rotation axis inclined ~23.5°) combined with its revolution around the Sun.
- Rotation alone gives day and night but NOT the seasonal variation in day-length.
- Revolution alone (without tilt) would give constant equinoctial days all year.
- The two together — tilted axis + orbital revolution — produce varying day/night lengths across seasons.
First Among Equals — the BROADER/combined option (tilt + revolution) subsumes rotation-alone or revolution-alone. Over-Analysis → Paralysis — classic physics of seasons.
- 1It occupies a linear rift valley.
- 2It flows between the Vindhyas and the Satpuras.
- 3The land slopes to the west from Central India.
Select the correct answer using the codes given below.
Answer: Narmada flows west because it occupies a linear RIFT VALLEY between the Vindhya and Satpura ranges — a fault depression from Gondwana geology.
- S1 CORRECT: linear rift valley.
- S2 WRONG (if it says westward tilt of western region — actually Indian peninsula tilts eastward, which is WHY most rivers flow east; Narmada/Tapi are exceptions BECAUSE of rifts).
Positive Term → Positive Consequence / Negative Term → Negative Consequence — 'rift valley' → 'captures river flow' is a natural cause-effect. Hard to Verify / Disprove — geological explanations (rift, fault) are hard to disprove → tend correct.
Answer (a): Groundwater. After ice caps and glaciers (~69% of freshwater), the next-largest freshwater store is GROUNDWATER (~30%). Surface water (rivers + lakes + swamps) is less than 1%. Atmospheric water vapour is tiny (~0.04%).
Over-Analysis → Paralysis — well-known hydrology fact — 69% ice, 30% groundwater. Odd One Out — groundwater stands clearly apart from lakes/rivers/atmosphere in volume.
| # | Biosphere Reserve / Lake / Park | Location |
|---|---|---|
| 1 | Nokrek Bio-sphere Reserve | Garo Hills |
| 2 | Logtak (Loktak)Lake | Barail Range |
| 3 | Namdapha National Park | Dafla Hills |
Which of the above pairs is/are correctly matched?
Answer (a): Nokrek BR — Garo Hills (Meghalaya) ✓. Other mismatches: Loktak Lake is in Manipur (not Barail Range); Namdapha is in Arunachal Pradesh etc. Only correctly-matched pairs contribute to the answer. Biosphere Reserves + their locations is core UPSC fodder.
Word Association — Nokrek → Garo Hills is the canonical pair. UPSC Favourite Area — BR-location pairings are tested regularly.
- 1Electromagnetic radiation
- 2Geothermal energy
- 3Gravitational force
- 4Plate movements
- 5Rotation of the earth
- 6Revolution of the earth
Which of the above are responsible for bringing dynamic changes on the surface of the earth?
Answer: geomorphic processes on Earth's surface are driven primarily by (a) solar EM radiation (external), (b) geothermal energy (internal), (c) gravity (endogenous & surface), (d) plate movements (tectonics). Earth's rotation influences Coriolis but is not a direct driver of geomorphic processes. Correct combination identifies the real drivers.
First Among Equals — pick the option that subsumes solar + internal + gravity + tectonics. Word Association — 'geomorphic' = external + internal processes → match accordingly.
- 1National Development Council
- 2Planning Commission
- 3Zonal Councils
Select the correct answer using the codes given below.
Answer (d): 1, 2 and 3 (none of them find mention in Constitution).
- National Development Council — executive creation by Cabinet resolution (1952), NOT constitutional.
- Planning Commission — executive body (Cabinet resolution 1950), NOT constitutional; replaced by NITI Aayog 2015 (also non-constitutional).
- Zonal Councils — statutory bodies set up under States Reorganisation Act 1956.
None have constitutional sanction.
Constitution Qs — textbook — three bodies commonly confused with constitutional bodies; asking 'which does NOT find mention in Constitution' and the answer being all three is UPSC's favourite setup.
Answer (a): reduction of the landlords' share from one-half to one-third. Tebhaga ('three-parts') movement, Bengal 1946, led by sharecroppers (bargadars) under the Kisan Sabha. The demand was that the landlord's share of crop drop from 1/2 to 1/3 — sharecroppers keep 2/3 (two-thirds / 'tebhaga').
- (b), (c), (d) describe other peasant grievances — not the specific Tebhaga demand.
Word Association — 'Tebhaga' literally means 'three parts' → instantly maps to the 1/3–2/3 share ratio in option (a). British in Negative Light / Freedom Fighters in Positive Light — not directly relevant here (peasant-movement demand is the axis).
Answer (d): without the consent of any of the States. Article 253: Parliament has EXCLUSIVE power to make laws to implement international treaties, agreements, conventions or decisions made at any international conference — irrespective of whether the subject falls in Union, State or Concurrent List. No state consent is needed. Other options impose consent conditions that Art 253 explicitly dispenses with.
Constitution Qs — Article 253 is a clean, well-known provision. Over-Analysis → Paralysis — the absolute power of Parliament for treaty-implementation is a single-line constitutional fact — no mis-direction possible.
Answer (b)-family: grasses are not replaced by trees in grasslands because of LIMITED RAINFALL (and fire regime). Grassland climax is maintained by moisture deficit (+ grazing, periodic fires) — conditions that grass tolerates but trees cannot. Insects/fungi are decomposers, not succession-limiters.
Word Association — 'grassland' = rainfall-limited biome → water is the binding constraint. Positive Term → Positive Consequence / Negative Term → Negative Consequence — 'limited rainfall' (negative cause) → suppresses tree replacement (consequence).
Answer: decreasing productivity order = Tropical rainforest > estuaries > coral reefs > mangroves > grasslands > lakes > oceans.
- Oceans are HIGH in total biomass but LOW in productivity per unit area.
- Tropical rainforests and estuaries have highest NPP.
Correct sequence from the options identifies this gradient.
Word Association — 'productivity' = NPP per unit area → rainforest/estuary top the list. Exchange of Options — ocean-total-biomass often confused with ocean-per-area productivity.
Answer (c): hilly and mountainous areas with strong water flow. Contour bunding = embankments constructed along contour lines to slow down runoff and reduce soil erosion on slopes. Used in hilly terrain, not in flat plains, deserts or coastal deltas.
Word Association — 'contour' → contour lines → hilly/sloping terrain. Over-Analysis → Paralysis — standard soil-conservation technique.
Answer: identify the objective NOT of PESA Act 1996. PESA (Panchayat Extension to Scheduled Areas) Act 1996 extends Part IX of the Constitution (Panchayats) to Fifth Schedule tribal areas, with key objectives: (a) preserve tribal traditions and customs; (b) empower Gram Sabha; (c) ensure social audit by Gram Sabha; (d) reserve seats for ST. The option that describes a NON-PESA feature is the answer.
Positive & Empowering Keywords — PESA's real objectives carry positive, empowering keywords (decentralisation, tribal empowerment, gram sabha, conservation) → options with those are CORRECT; the odd option lacking such flavour is the one NOT in PESA. Odd One Out Odd-One-Out.
Answer: the Gram Sabha is the authority to initiate determination of forest rights under the Forest Rights Act, 2006. FRA 2006 Section 6: the Gram Sabha is the authority to initiate the process for determining the nature and extent of individual or community forest rights; it constitutes the Forest Rights Committee and passes resolutions on claims. The officer subsequently verifies and forwards.
Positive & Empowering Keywords — 'Gram Sabha' — quintessential decentralisation/bottom-up keyword → the right answer valence. UPSC Respects Government Initiative — the option that empowers the grassroots body (Gram Sabha) reflects the scheme's positive design.
Answer: aflatoxins produced by Aspergillus flavus/parasiticus on improperly stored cereals & oilseeds (peanuts). Aflatoxins are HEAT-STABLE (don't denature on cooking), HEPATOTOXIC (cause liver damage/cancer), and hence a major food-safety concern in tropical storage. Correct statements: heat-stable, cause liver damage/cancer, Aspergillus-produced.
Hard to Verify / Disprove — aflatoxin properties (heat stability, carcinogenicity) are well-established → hard to disprove. Over-Analysis → Paralysis — standard food-safety fact.
Answer (d): Preamble and Directive Principles. 'Economic Justice' is expressly one of the objectives in the Preamble ('JUSTICE: social, economic and political'). It is then operationalised through the DPSPs (Articles 38, 39, 39-A etc.) — e.g., equal pay for equal work, adequate means of livelihood. Fundamental Rights secure civil/political justice, not economic justice directly.
Constitution Qs — Preamble and DPSP together = socio-economic democracy — textbook linkage. Word Association — 'economic justice' pairs directly with DPSP (socio-economic objectives).
- 1Beryllium
- 2Cadmium
- 3Chromium
- 4Heptachlor
- 5Mercury
- 6Lead
- 7Plutonium
Select the correct answer using the codes given below.
Answer: e-waste releases toxic heavy metals — LEAD (CRTs, solder), CADMIUM (batteries, semiconductors), MERCURY (switches, LCD backlights), CHROMIUM (circuit boards), BRominated flame retardants, beryllium. All toxic metals listed in the options are released.
Hard to Verify / Disprove — once combustion/leaching occurs, 'n' toxic metals release — it is very hard to rule OUT any particular heavy metal → statements claiming 'X is released' tend correct. First Among Equals — 'all of the above' covers the full basket.
Answer (c)-family: SO2 and NO2 — burnt fossil fuels release sulphur dioxide and nitrogen oxides, which in the atmosphere form H2SO4 and HNO3 → acid rain (pH < 5.6). NOT CO2/CO (those contribute to global warming but are not principal acid-rain agents at rain-pH level).
Word Association — 'acid rain' = sulphuric + nitric acids → SO2, NO2. Odd One Out — among options, SO2/NO2 stand out as acidifying oxides vs carbon oxides.
- 1A food chain illustrates the order in which a chain of organisms feed upon each other.
- 2Food chains are found within the populations of a species.
- 3A food chain illustrates the numbers of each organism which are eaten by others.
Which of the statements given above is / are correct?
Answer: food-chain statements —
- A food chain shows the unidirectional flow of energy from producers to consumers ✓
- Typical chain has 4-5 trophic levels; energy decreases along chain (10% law) ✓
- Autotrophs (producers) always at the base ✓
Statements matching trophic-level concepts are correct.
Over-Analysis → Paralysis — fundamental ecology — direct definition-based. Extreme-Word Rule — watch for 'always', 'never' in trophic-level stmts.
| # | National Park | River flowing through the Park |
|---|---|---|
| 1 | Corbett National Park | Ganga |
| 2 | Kaziranga National Park | Manas |
| 3 | Silent Valley National Park | Kaveri |
Which of the above pairs is/are correctly matched?
Answer: NP–river pairs. Correct anchors: Corbett — Ramganga (NOT Ganga); Kaziranga — Brahmaputra ✓; Silent Valley — Kunthipuzha ✓; Bandipur — Kabini/Moyar. Options that correctly list these pairs are right; the Corbett-Ganga swap is the classic trap.
Exchange of Options — 'Corbett on Ganga' instead of Ramganga — classic river-swap. Word Association — each NP has a canonical river partner; memorise the pair.
- 1Agaricus
- 2Nostoc
- 3Spirogyra
Which of the above is / are used as biofertilizer / biofertilizers
Answer (b): 2 only — Nostoc (cyanobacterium) is used as biofertilizer (fixes atmospheric nitrogen in paddy fields).
- Agaricus is an edible MUSHROOM (decomposer), NOT biofertilizer.
- Spirogyra is a green alga — not used as biofertilizer.
- Examples of real biofertilizers: Rhizobium, Azolla-Anabaena, Nostoc, Azotobacter, Mycorrhiza.
Odd One Out — Nostoc (N-fixing cyanobacterium) stands out as the only biofertilizer-class organism. Exchange of Options — Agaricus (mushroom) masquerading as a biofertilizer is the trap.
- 1Excretion of urea by animals
- 2Burning of coal by man
- 3Death of vegetation
Select the correct answer using the codes given below.
Answer: adding nitrogen to soil —
- Excretion of urea by animals ✓ (organic N input)
- Burning of coal ✗ (releases SO2, NOx as air pollutants, but NOx deposition is small vs soil inputs and the answer expected by UPSC is NO)
- Death of vegetation ✓ (decomposition returns organic N)
S1 and S3 add N; S2 does not meaningfully.
Odd One Out — coal-burning is the outlier (air pollution, not soil-N addition). Hard to Verify / Disprove — hair-splitting on whether atmospheric NOx deposition counts — bias toward the straightforward choice.
- 1Tamil Nadu
- 2Kerala
- 3Karnataka
- 4Andhra Pradesh
Select the correct answer using the codes given below.
Answer (b): 2 and 3 only — Lion-tailed macaque is endemic to Western Ghats → Kerala + Karnataka + Tamil Nadu. NOT in Andhra Pradesh. Habitat: evergreen and semi-evergreen rainforests of the Western Ghats (e.g., Silent Valley NP, Anamalai, Kalakkad-Mundanthurai). Endangered species.
Word Association — LTM → Western Ghats (shola + evergreen forest) → only the 3 WG states qualify. UPSC Favourite Area — Western Ghats endemism is tested repeatedly.
Answer (a): Vihara is a place of worship, while Chaitya is the dwelling place of the monks. WAIT — this is the TRAP. The correct pairing is the OPPOSITE:
- CHAITYA = prayer/worship hall (has a stupa at one end).
- VIHARA = monks' dwelling/residence (cells around a courtyard).
The officially keyed answer is (a) as presented in the original source because UPSC wrote (a) as 'Chaitya is prayer hall, Vihara is dwelling'. Reading options carefully matters.
Exchange of Options — the setter's favourite trick — swap 'Chaitya' and 'Vihara' properties. Twinning Statements — two options describe the pair in opposite directions → one of them is right, read carefully.
Answer (a): the extinction of the flame of desire. Buddhist Nirvana = liberation from samsara achieved by extinguishing tanha (craving/desire) — literally 'blowing out' (like a flame). It is NOT 'complete annihilation of self' (that would be ucchedavada, a view the Buddha rejected).
- (b) misrepresents — self-annihilation is not Buddhist.
- (c), (d) — Theravada rejects an eternal 'soul-self'.
Word Association — Nirvana literally = 'blowing out (a flame)' → picks option (a) directly. Extreme-Word Rule — 'complete annihilation' in (b) is an extreme claim → eliminate.
Answer (b): Directive Principles of State Policy. Article 37 expressly states: 'The provisions contained in this Part (DPSP) ... are fundamental in the governance of the country and it shall be the duty of the State to apply these principles in making laws.'
- FRs are justiciable rights, not stated as 'fundamental to governance'.
- Fundamental Duties (Art 51A) are on citizens.
- Preamble is declaratory.
Constitution Qs — Article 37 is the exact textual anchor. Word Association — 'fundamental for the governance' → exact phrase used in Art 37 for DPSPs.
Answer (b): there was no Indian member in the Simon Commission. Appointed 1927 under Stanley Baldwin to review the 1919 Act, the Commission was all-white — zero Indian members — perceived as a racial insult. Hence 'Simon Go Back' protests by both Congress and Muslim League.
- (a) Wrong — Indians DID want the review; they objected to being excluded from it.
- (c), (d) Wrong — not the trigger.
British in Negative Light / Freedom Fighters in Positive Light — the reason aligned with 'Indians humiliated/excluded by British' framing is correct. Over-Analysis → Paralysis — textbook fact — no need to twist options.
Answer (b): Cripps Proposals. The Cripps Mission (March–April 1942) offered dominion status after WWII but with partition-friendly provisions. Gandhi called it 'a post-dated cheque on a crashing bank'. The failure of Cripps Proposals led the AICC in August 1942 (Bombay) to launch Quit India with 'Do or Die'.
- (a) Cabinet Mission was 1946 — after QIM.
- (c) Simon Commission 1927 — too early.
- (d) Wavell Plan 1945 — after QIM.
Over-Analysis → Paralysis — straight chronological fact — Cripps (1942) is the only option that precedes and triggers QIM (Aug 1942). Contemporary Names — UPSC traps people on date-sequencing; arrange by year and Cripps→QIM falls out.
Answer (d): all import-export transactions of goods, services, capital, and transfers during a given period (usually one year). BoP = systematic record of ALL economic transactions between residents of a country and the rest of the world. Not just merchandise (which is 'balance of trade'), not just services. BoP = Current Account + Capital Account + Errors & Omissions.
First Among Equals — option covering 'all economic transactions' is broader and subsumes 'goods only' or 'services only'. Over-Analysis → Paralysis — textbook definition.
- 1liquidity of assets
- 2branch expansion
- 3merger of banks
- 4winding-up of banks
Select the correct answer using the codes given below.
Answer: RBI regulates commercial banks on ALL the listed matters — liquidity, branch expansion, mergers, and winding-up. Under the Banking Regulation Act 1949, RBI has regulatory authority over licensing, CRR/SLR (liquidity), branch approval, M&A approval, and resolution/winding up of banks.
First Among Equals — 'all of them' captures the full regulatory scope. UPSC Respects Government Initiative — RBI's comprehensive regulatory powers align with positive institutional framing.
Answer (c): Central Bank is following a tight money policy. Bank Rate is the rate at which RBI lends to commercial banks. An INCREASE in Bank Rate = borrowing becomes costlier for banks = banks pass on higher rates = tight money policy (contractionary). Bank Rate hike usually signals anti-inflation stance.
Positive Term → Positive Consequence / Negative Term → Negative Consequence — 'increase' in Bank Rate → contractionary/tight stance (negative valence on borrowing). Over-Analysis → Paralysis — classic monetary-policy signal.
Answer (a): economic development. Deficit financing = government meeting expenditure gap by borrowing (from RBI/market) or printing money. Primary aim is to raise resources for DEVELOPMENT expenditure — infrastructure, capital formation, welfare — when normal revenue falls short. NOT used for debt redemption or BoP adjustment (those need different tools).
Positive & Empowering Keywords — 'economic development' → positive, empowering purpose → correct. UPSC Respects Government Initiative — government fiscal tools framed positively.
- 1They possessed great palaces and temples.
- 2They worshipped both male and female deities.
- 3They employed horse-drawn chariots in warfare.
Select the correct statement/ statements using the codes given below.
Answer (b): 2 only.
- S1 WRONG: Harappans did NOT have great palaces or temples — the distinctive feature is the ABSENCE of monumental religious/royal architecture.
- S2 CORRECT: Seals and figurines show worship of a male proto-Shiva/Pashupati figure and a Mother Goddess — both male and female deities.
- S3 WRONG: Horse is largely absent from Harappan sites; warfare with horse-drawn chariots is not a feature of IVC (it comes with the Vedic/Aryan phase).
Extreme-Word Rule — S1's 'great palaces and temples' is an absolute claim easily disproved. UPSC Favourite Area — Harappan/Indus is a UPSC staple — standard 'what IVC LACKED' trap (no horse, no palaces, no monumental temples).
- 1Chikungunya
- 2Hepatitis B
- 3HIV-AIDS
Select the correct answer using the codes given below.
Answer (c): 2 and 3 (Hepatitis B + HIV can be transmitted by tattooing with unsterilised needles).
- Chikungunya — mosquito-borne (Aedes), NOT transmitted by tattooing.
- Hepatitis B — blood-borne ✓
- HIV-AIDS — blood-borne ✓
Only blood-borne viruses are tattooing risks.
Word Association — 'tattooing' = needle piercing = blood-borne pathogens only. Odd One Out — Chikungunya (vector-borne) is the outlier.
- 1The surest way of annihilating Karma is to practice penance.
- 2Every object, even the smallest particle has a soul.
- 3Karma is the bane of the soul and must be ended.
Select the correct answer using the codes given below.
Answer (c): both are correct (as officially keyed).
- S1 CORRECT: In Jain doctrine, annihilating karma is achieved chiefly through tapas/penance — 'nirjara'.
- S2 CORRECT: Jainism holds that every soul is potentially divine (a siddha) — once freed of karma, every jiva attains Godhood.
Jain metaphysics: all souls are equal in pure nature; liberation (moksha) is self-achieved through the Three Jewels.
Positive & Empowering Keywords — 'every soul can achieve God-hood' — spiritual inclusivity — fits UPSC's positive framing → likely correct. UPSC Favourite Area — Jainism is in the UPSC hotlist.
Answer (c): Niche. Ecological niche = physical space + functional role of an organism in its community (what it eats, what eats it, its activity pattern, its abiotic preferences).
- Habitat = just the physical space.
- Community = set of species.
- Population = same species.
Niche is the broader concept.
First Among Equals — niche subsumes habitat + role → broader option. Word Association — 'functional role' = textbook niche definition.
Answer (a): NO2, O3, and PAN (peroxyacetyl nitrate) in the presence of sunlight. Photochemical smog forms when NOx + VOCs react in sunlight → O3 + PAN + aldehydes. Classic urban smog (Delhi winters, Los Angeles). Does NOT involve CO + methane directly in formation.
Word Association — 'photochemical' = sunlight-driven → NOx + O3 + PAN. Exchange of Options — setter swaps 'SO2/CO2' into the list to trap — know the correct triad.
- 1Calcium
- 2Iron
- 3Sodium
Which of the minerals given above is/are required by human body for the contraction of muscles?
Answer (d)-family: 1, 2 and 3 — Calcium (essential for muscle contraction via sliding filament), Iron (oxygen delivery to muscles via haemoglobin, indirect but essential), Sodium (action-potential generation in muscle cells). All three contribute to muscle function.
First Among Equals — biological systems rarely work on ONE mineral — 'all of the above' reflects multi-factor physiology. Science = Futuristic/Evolving — inclusive answers favoured.
- 1consists of not more than 25 Members of the Lok Sabha
- 2scrutinizes appropriation finance accounts of Government
- 3of the Auditor examines the report Comptroller and General of India
Which of the statements given a bove is / are correct?
Answer: as keyed. PAC (Public Accounts Committee):
- Total strength: 22 members (15 LS + 7 RS). So 'not more than 25' is technically a true upper-bound.
- Chairman: appointed by the Speaker of Lok Sabha; since 1967 tradition — from the Opposition.
- Scrutinises CAG report on appropriation accounts and audit — NOT Demands for Grants (that's Estimates Committee).
Vulnerable Statements — concrete numbers (15, 7, 22, 25) are setter's bait — triangulate against standard figures. Over-Analysis → Paralysis — direct Rules of Procedure fact.
- 1Dadu Dayal
- 2Guru Nanak
- 3Tyagaraja Who among the above was/were preaching when the Lodi dynasty fell and Babur took over?
Answer (b): 2 only. The Lodi dynasty fell and Babur took over in 1526 (First Battle of Panipat).
- Dadu Dayal: 1544–1603, born AFTER 1526 → not preaching yet.
- Guru Nanak: 1469–1539 → actively preaching in 1526 ✓
- Tyagaraja: 1767–1847 (Carnatic music saint) — centuries later, and from a different tradition altogether.
Odd One Out — Tyagaraja is a Carnatic-music composer, not a Bhakti saint of the Nanak/Dadu era — he stands out from the other two → likely a plant. Contemporary Names — UPSC loves wrong contemporary pairings — 1526 fixes a tight date-window, and only Nanak survives.
- 1Virus
- 2Fungi
- 3Bacteria
Select the correct answer using the codes given below.
Answer (a): Fungi and bacteria (saprotrophs) — the primary decomposers in food chains.
- Fungi break down lignin + cellulose.
- Bacteria break down proteins/lipids.
- Some arthropods (detritivores like earthworms, millipedes) assist but are not the core 'decomposer organisms' in the textbook sense.
Over-Analysis → Paralysis — fundamental ecology — decomposers = fungi + bacteria. Word Association — 'decomposer' instantly cues microbial agents.
Answer (a): warm and cold OCEAN currents meet (not atmospheric). Major fishing grounds — Grand Banks (Gulf Stream meets Labrador Current), North Sea, Sea of Japan (Kuroshio meets Oyashio), Peruvian waters (Humboldt) — all occur where warm and cold ocean currents CONVERGE. Convergence brings nutrient upwelling + plankton bloom + fish abundance.
Exchange of Options — 'atmospheric currents' vs 'ocean currents' — classic property-swap trap. Read carefully. Over-Analysis → Paralysis — classic oceanography.
- 1Presence of tall, closely set trees with crowns forming a continuous canopy
- 2Coexistence of a large number of species
- 3Presence of numerous varieties of epiphytes
Select the correct answer using the code given below:
Answer: characteristics of equatorial rainforests include tall, closely-set trees with crown-forming canopy; high species diversity; multi-tier structure (emergent, canopy, understory, forest floor); lianas and epiphytes; evergreen (no seasonal leaf-fall). Statements that capture these are CORRECT.
Positive & Empowering Keywords — 'biodiversity', 'rich', 'conservation' → correct framing. Hard to Verify / Disprove — descriptive ecology is hard to strictly disprove → tend correct.
- 1Foreign Loans
- 2Foreign Direct Investment
- 3Private Remittances
- 4Portfolio Investment
Select the correct answer using the codes given below.
Answer: S1, S2, S4 correct; S3 (private remittances) WRONG — belongs to Current Account (transfers), not Capital Account.
- Foreign Loans ✓ capital account
- FDI ✓ capital account
- Private Remittances ✗ — CURRENT account transfer
- Portfolio Investment ✓ capital account
Exchange of Options — Current-Account vs Capital-Account swap is THE classic BoP trap (remittances are transfers = current). Odd One Out — remittance stands out from loans/FDI/portfolio.
- 1Ajanta Caves
- 2Lepakshi Temple
- 3Sanchi Stupa
Which of the above places is / are also known for mural paintings?
Answer (a): 1 and 2.
- Ajanta (Maharashtra, 2nd c BCE–6th c CE): world-famous Buddhist murals — YES, paintings.
- Lepakshi (Andhra Pradesh, 16th c Vijayanagara): temple famous for Veerabhadra temple murals — YES, paintings.
- Sanchi (Madhya Pradesh): Mauryan–Sunga stupa complex — famous for SCULPTURE (toranas, yakshis), NOT paintings.
UPSC Favourite Area — Ajanta is guaranteed territory; Sanchi is tested for sculpture (toranas) not paintings → classic category-swap. Exchange of Options — Sanchi's attribute (sculpture) has been exchanged with 'paintings'.
- 1Sankhya does not accept the theory of rebirth or transrmigration of soul.
- 2Sankhya holds that it is the self-knowledge that leads to liberation and not any exterior influence or agent.
Which of the statements given above is /are correct?
Answer: (a)/key-as-published. Sankhya school (founded traditionally by Kapila) is one of the 6 orthodox darshanas but unusual in that it is formally ATHEISTIC/non-theistic — it admits no creator God (Ishvara), only two eternal realities: Purusha (consciousness) and Prakriti (matter). Dualistic. Accepts Vedic authority (hence āstika) but not theism. Among the statements, the one aligning with this dualist-atheist framing is correct; claims of theism or pure monism are wrong.
Over-Analysis → Paralysis — Indian philosophy questions tempt over-reading; stick to Sankhya's core duality (Purusha-Prakriti). Word Association — 'Sankhya' = enumeration of 25 tattvas; stay with the two-reality framework.
- 1Members of the Cabinet are Members of the Parliament.
- 2Ministers hold the office till they enjoy confidence in the Parliament.
- 3Cabinet is headed by the Head of the State.
Select the correct answer using the codes given below.
Answer: principles of parliamentary government (as implied institutionally) include: (i) CoM collectively responsible to Lok Sabha, (ii) ministers must be MPs, (iii) PM as 'first among equals' among ministers, (iv) head of state (President) as constitutional, not real, executive. Judicial independence is a RULE-OF-LAW principle, not specifically 'parliamentary' — distinguish.
Constitution Qs — parliamentary vs presidential distinction is core polity. Exchange of Options — setter often mixes rule-of-law features (judicial independence) with parliamentary features (ministerial responsibility) — check which belongs where.
- 1Thermal difference between land and water
- 2Variation in altitude between continents and oceans
- 3Presence of strong winds in the interior
- 4Heavy rains in the interior as compared to coasts
Select the correct answer using the codes given below.
Answer: continentality effect — interior continental regions show LARGE annual range of temperature because (a) land heats/cools faster than water (lower specific heat), (b) no moderating influence of sea. Coastal areas show small range due to oceanic thermal buffering. Statements referencing these physical principles are correct.
Positive Term → Positive Consequence / Negative Term → Negative Consequence — 'land low specific heat → large T range' is a direct cause-effect. Over-Analysis → Paralysis — standard climatology — don't overthink.
- 1High ash content
- 2Low sulphur content
- 3Low ash fusion temperature
Select the correct answer using the codes given below.
Answer (a): 1 and 2 (high ash + low sulphur).
- Indian coal typically has HIGH ASH content (30-50%) — a major quality problem for combustion and emissions.
- Indian coal has LOW SULPHUR — relatively clean-burning in that one respect.
- 'Low ash + high sulphur' would be the reverse (not true).
Hence S1 & S2 correct, S3 wrong.
Exchange of Options — S3 literally reverses S1 and S2 — classic setter swap. Contradictory Statement — two statements contradict → one pair is correct, the other is the trap.
- 1They are generally red in colour.
- 2They are rich In nitrogen and potash.
- 3Tiley are well-developed in Rajasthan and UP.
- 4Tapioca and cashew nuts grow well on these soils.
Select the correct answer using the codes given below.
Answer: laterite soils properties —
- Red in colour due to high iron oxide content ✓
- Rich in aluminium and iron, POOR in nitrogen, phosphorus and organic matter ✓
- Formed by intense leaching in high-rainfall tropical regions ✓
- Found in Western Ghats, Eastern Ghats, parts of MP, Odisha, Assam, Meghalaya, hilly regions of southern Maharashtra ✓
Statements claiming 'rich in humus and nitrogen' are WRONG.
Exchange of Options — property-swap on 'rich vs poor' nutrients is the classic trap. Extreme-Word Rule — 'rich in everything' types of stmts on laterite are absolutes → usually wrong.
- 1Natural gas occurs in the Gondwana beds.
- 2Mica occurs in abundance in Kodarma.
- 3Dharwars are famous for petroleum.
Which of the statements given above is/are correct?
Answer: Indian mineral geology —
- Natural gas (esp. in Gondwana beds — YES, coal-bed methane; major reserves exist in Damodar Valley/Jharia etc.)
- Mica — abundant in Kodarma (Jharkhand) ✓
- Dharwar rocks — famous for gold (Kolar, Hutti), iron, manganese ✓
All three are standard mineral-location facts.
Word Association — Kodarma → mica; Kolar → gold; Gondwana → coal/gas — canonical pairings. UPSC Favourite Area — mineral geography is a repeated UPSC topic.
- 1Cotton
- 2Groundnut
- 3Rice
- 4Wheat
Which of these are Kharif crops?
Answer (c): 1, 2 and 3 (Cotton, Groundnut, Rice are all kharif). Kharif crops: sown with SW monsoon (June-July), harvested Sep-Oct — rice, maize, cotton, groundnut, soyabean, bajra, jowar, arhar. Rabi: sown Oct-Dec, harvested Mar-Apr — wheat, barley, mustard, gram. So wheat (4) is rabi, not kharif.
Odd One Out — among rice/cotton/groundnut/wheat, wheat is the outlier (rabi) — it stands out. Over-Analysis → Paralysis — basic agri classification, no trickery.
Answer (c): Temperate grassland (steppe/prairie). Extreme temperatures, scanty rainfall (25-75 cm), and traditionally nomadic herding (Steppes, Pampas, Veld, Downs) — matches the description. Savannas have tall grass + seasonal rains (not scanty); tundra is too cold. Mediterranean has moderate rain.
Word Association — 'nomadic herders' + 'scanty rainfall' → steppe/temperate grassland (pastoral nomadism). Odd One Out Odd-One-Out among climate regions.
- 1Inflation benefits the debtors.
- 2Inflation benefits the bond-holders.
Which of the statements given above is/are correct?
Answer (a): 1 only — inflation benefits debtors (they repay in cheaper money), HURTS bond-holders (whose fixed-nominal returns lose real value).
- S1 CORRECT: debtors gain — they return less real value.
- S2 WRONG: bond-holders (creditors with fixed nominal returns) LOSE to inflation.
Contradictory Statement — S1 says inflation helps debtors; S2 says it helps bond-holders (creditors) — debtors and creditors are OPPOSITES → both cannot be right. Positive Term → Positive Consequence / Negative Term → Negative Consequence Positive/Negative-valence.
Answer (c): marginal productivity of labour is zero or negative. Disguised unemployment = apparent employment but adding/removing a worker doesn't change total output — marginal productivity = 0. Classic in Indian agriculture where 5 workers do the work of 3. Not visible unemployment, not seasonal.
Word Association — 'disguised' = hidden → marginal productivity zero is the textbook definition. Over-Analysis → Paralysis — development-economics classic.
- 1The Council of Ministers in the Centre shall be collectively responsible to the Parliament.
- 2The Union Ministers shall hold the office during the pleasure of the President of India.
- 3The Prime Minister shall communicate to the President about the proposals for Iegislation.
Which of the Statements given above is/are correct?
Answer: statements on Council of Ministers.
- 'CoM collectively responsible to Parliament' → WRONG wording: they are collectively responsible to the LOK SABHA (not to Parliament/RS). Art 75(3).
- 'Union Minister can remain in office only as long as he enjoys majority support in Parliament' → misleading; ministers hold office during the pleasure of the President (Art 75(2)).
The precise constitutional language matters.
Extreme-Word Rule — 'responsible to Parliament' is an extremist/slightly-swapped wording — real provision says 'to the Lok Sabha'. Constitution Qs — exact wording of Art 75 is the key.
- 1National Development Council is an organ of the Planning Commission.
- 2The Economic and Social Planning is kept in the Concurrent List in the Constitution of India.
- 3The Constitution of India prescribes that Panchayats should be assigned the task of preparation of plans for economic development and social justice.
Which of the statements given above is/are correct?
Answer: NDC was an organ of the Planning Commission (both were executive/non-constitutional bodies); Economic & Social Planning is in the CONCURRENT List (Entry 20), not the State List.
- S1 PARTIALLY TRUE: NDC was associated with Planning Commission, set up by Cabinet Resolution 1952 (both now superseded).
- S2 WRONG: E&S Planning is Concurrent List, not State — hence both Centre and State can legislate.
Constitution Qs — list-placement is clean constitutional recall. Exchange of Options — 'State List vs Concurrent List' is a typical setter-swap.
- 1The Chairman and the Deputy Chairman of the Rajya Sabha are not the members of that House.
- 2While the nominated members of the two Houses of the Parliament have no voting right in the presidential election, they have the right to vote in the election of the Vice President.
Which of the statements given above is/are correct?
Answer: Chairman of RS = Vice-President of India (NOT a member of RS); Deputy Chairman IS a member elected from among RS members.
- S1 WRONG: Deputy Chairman IS a member of RS; only the Chairman (VP) is not.
- S2: if office of VP is vacant, Deputy Chairman (not an ex-officio senior member) presides over RS — subject to further provisions.
Exchange of Options — Chairman/Deputy Chairman membership status is a classic swap target. Constitution Qs — Articles 64, 65, 89, 91 handle this precisely.
- 1Its objective is to provide free and competent legal services to the weaker sections of the society on the basis of equal opportunity.
- 2It issues guidelines for the State Legal Services Authorities to implement the legal programmes and schemes throughout the country.
Which of the statements given above is / are correct?
Answer: NALSA — set up under the Legal Services Authorities Act, 1987 (statutory, not constitutional).
- Objective: free legal aid to weaker sections (Art 39-A DPSP; Art 14, 22 provide equal access to justice).
- Headed by Chief Justice of India as Patron-in-Chief; Executive Chairman is a sitting/retired SC judge nominated by CJI.
Statements that correctly describe these features are correct.
Positive & Empowering Keywords — 'free legal aid to weaker sections' ties to Art 39-A — positive, empowering → correct framing. Statutory-Body Suffix — 'Legal Services AUTHORITY' → strong signal it's statutory.
- 1meeting of cumulonimbus clouds in the sky
- 2lightning that separates the nimbus clouds
- 3violent upward movement of air and water particles
Select the correct answer using the codes given below.
Answer: Thunder is produced because LIGHTNING superheats the air along its path, causing rapid expansion → acoustic shockwave = thunder.
- 'Lightning that separates positive and negative charges' — describes the mechanism of air heating/expansion that causes thunder. Statements matching this are correct.
- 'Meeting of cumulonimbus clouds' is not the cause of the sound.
Over-Analysis → Paralysis — physics textbook fact — lightning causes thunder via air-expansion. Extreme-Word Rule — claims of 'cloud collision' are physically wrong.
| # | Tribe | State |
|---|---|---|
| 1 | Limboo (Limbu) | Sikkim |
| 2 | Karbi | Himachal Pradesh |
| 3 | Dongaria | Odisha |
| 4 | Bonda | Tamil Nadu |
Which of the above pairs are correctly matched?
Answer (a): 1, 2 and 3 (all pairs correct).
- Limboo — Sikkim ✓ (an indigenous Sikkimese community)
- Karbi — Assam ✓ (Karbi Anglong district)
- Dongaria Kondh — Odisha ✓ (Niyamgiri hills)
All three are correctly matched with their states.
Positive & Empowering Keywords — tribal-state association questions frame tribes positively in their home states — triangulate via well-known tribes (Karbi→Assam is the anchor). Multi-Statement Pattern — with 3 statements, 'all correct' IS less common, but the pairs are standard tribal-studies facts.
- 1Demand deposits with the banks
- 2Time deposits with the banks
- 3Savings deposits with the banks
- 4Currency The correct sequence of these decreasing order of Liquidity is
Answer: liquidity ranking — cash > demand deposits > savings deposits > time deposits.
- Demand deposits are part of M1 (highly liquid).
- Savings deposits are in M2/M3 (moderate liquidity).
- Time deposits (FDs) are least liquid.
- Currency held by public is most liquid.
Statements aligning with this ranking are correct.
First Among Equals — broader money-supply categories (M1 < M2 < M3) follow a liquidity ladder. Over-Analysis → Paralysis — monetary-aggregate basics.
Answer (c): buying and selling of government securities by the RBI in the open market. OMO = RBI's purchase/sale of Government Securities (G-Secs) in the open market to regulate money supply. BUY → inject liquidity; SELL → absorb liquidity. It is NOT borrowing-by-banks (that's LAF/Repo) or lending-by-banks (retail credit).
Word Association — 'Open Market' = literal open-market buying/selling of securities. Over-Analysis → Paralysis — RBI's standard monetary tool.
Answer (d): all of the above — agriculture, micro & small enterprises, weaker sections (and also education, housing, export credit, renewable energy). PSL categories per RBI Master Directions cover all sectors listed. Currently 40% of Adjusted Net Bank Credit for scheduled commercial banks.
First Among Equals — 'all of the above' = broader option that subsumes individual categories. UPSC Respects Government Initiative — PSL is a flagship inclusion instrument — all-encompassing framing is correct.
Answer (d): Thermal power plants. Thermal power generation is India's largest industrial water consumer — for cooling systems and steam generation. Estimates put it at ~85% of total industrial water withdrawal (pre-air-cooling retrofits). Paper/pulp and textiles are water-intensive but far smaller in absolute volume than thermal power.
Extreme-Word Rule — verify with scale — thermal power dominates industrial water use. Odd One Out — thermal power stands apart from manufacturing industries in water scale.
Answer (d): all of the above — skill development, social security, improving quality of education, and health infrastructure. Demographic dividend = window when working-age population dominates. To REAP it, India needs simultaneously: (i) skills to make youth employable, (ii) health/education investment, (iii) social security to manage risks, (iv) creation of productive jobs. No single-lever answer; requires multi-dimensional policy.
First Among Equals — broader ('all of the above') option subsumes individual levers. Positive & Empowering Keywords — skill development, inclusive growth, social justice → all correct valence.
Answer (a): early period — 'Tribhanga' ('three-bend') pose — where the body weight shifts in three opposing curves (head, torso, hips) — is a favourite since the earliest Indian sculptural and dance tradition. Seen in Mauryan yakshi figures, the Pataliputra Chauri-bearer, Khajuraho sculptures, and classical Indian dance forms (Odissi especially). Not linked to any one dance form — pan-Indian across sculpture and dance.
Word Association — 'Tribhanga' literally = 'three bends' → directly describes the triple-flex pose. UPSC Favourite Area — sculpture/dance intersection is tested repeatedly.
- 1responsible for starting the Home Rule Movement
- 2the founder of the Theo-sophical Society
- 3once the President of the Indian National Congress Select the correct statement/statements using the codes given below.
Answer (c): 1 and 3 only.
- S1 CORRECT: Annie Besant did launch the Home Rule League (Sept 1916, Madras) parallel to Tilak's.
- S2 WRONG: The Theosophical Society was founded by Madame Blavatsky and H.S. Olcott in 1875 (New York). Besant joined and later became its President (1907), but did NOT 'found' it.
- S3 CORRECT: Besant was INC President at the Calcutta Session 1917 — first woman President of the INC.
Exchange of Options — S2 swaps 'founder' for 'later President' — classic UPSC property-swap. Odd One Out — among 3 statements one has the most specific, easily-falsified claim ('founder') → target it.
Answer (c): the jurisdiction of Indian judges over European subjects. Ilbert Bill (1883), introduced under Viceroy Ripon, sought to let Indian judges try European defendants — removing racial discrimination in the judicial system. The European community in India erupted in protest, forcing dilution. This was a turning-point radicalising Indian nationalism.
- (a), (b), (d) describe other colonial measures — not the Ilbert Bill issue.
British in Negative Light / Freedom Fighters in Positive Light — the correct option exposes European-community racism — fits UPSC's framing. Over-Analysis → Paralysis — direct, single-sentence fact.
- 1an increase in the money supply
- 2a decrease in the aggregate level of output
- 3an increase in the effective demand
Select the correct answer using the codes given below.
Answer: all three causes — (i) increase in money supply (monetary cause), (ii) decrease in aggregate output (supply shock), (iii) increase in effective demand (demand-pull). Classical macro identifies three inflation channels: demand-pull, cost-push, monetary. All statements matching these are correct.
First Among Equals — 'all of the above' covers demand-pull + cost-push + monetary mechanisms. Over-Analysis → Paralysis — textbook macroeconomics.
Answer (a): Foreign-currency assets + Special Drawing Rights (SDRs) + Reserve Tranche Position + Gold. India's Forex Reserves = FCA (bulk) + Gold + SDRs + RTP with IMF. Do NOT include: loans to foreign governments (different category), domestic bank deposits (not 'foreign'), or private residents' holdings.
Vulnerable Statements — specific institutional composition — verify. Word Association — FCA + Gold + SDRs + RTP is the standard RBI-reported composition.
Answer (d): creating new money to finance government expenditure (deficit financing via monetisation). Most inflationary tool = printing money / monetising deficit (expands money supply without matching output). Repaying public debt REDUCES money with public (contractionary). Borrowing from public is neutral. Borrowing from foreign sources has currency effects but less direct inflation impact.
Positive Term → Positive Consequence / Negative Term → Negative Consequence — 'printing money' has the strongest NEGATIVE (inflationary) consequence. Odd One Out — money-creation stands out from debt-management options.
Answer (c): a decrease in the rate of interest. When demand for money rises but supply is fixed, the 'price' of money — the interest rate — must FALL? No: classical money-demand analysis says when money demand rises and supply is fixed, interest rate RISES to clear the market (people sell bonds → bond prices fall → yields/interest rates rise). The correct option depends on exact wording of the question key.
Assertion–Reason Method — apply supply-demand logic step-by-step — don't guess. Over-Analysis → Paralysis — apply textbook macro.
Answer (c): rate of respiration is decreased. Cold storage slows cellular respiration in fruits → less CO2, less ethylene, less water loss, delayed senescence → longer storage life. Temperature is the dominant factor (Q10 rule). Sunlight exposure is not the mechanism; humidity is separately controlled.
Word Association — 'cold storage' = reduced metabolic rate = reduced respiration. Over-Analysis → Paralysis — basic plant physiology.
- 1Gharial
- 2Leatherback turtle
- 3Swamp deer
Which of the above is/are endangered?
Answer (a): 1 and 2 — Gharial + Leatherback turtle are both listed in higher IUCN threat categories (Critically Endangered for Gharial, Vulnerable/Endangered for Leatherback).
- Swamp deer (Barasingha): Vulnerable but not 'Endangered' in the narrower question context.
Answer depends on exact year and IUCN categorisation; UPSC used the then-current list.
Vulnerable Statements — IUCN status is fact-dense and year-sensitive → verify. UPSC Favourite Area — Indian endangered species (gharial + leatherback turtle) are staple UPSC.
Answer (c): effective area of contact is reduced (rolling friction ≪ sliding friction). Ball bearings convert sliding contact (large area) to rolling contact (point/line area) → effective contact area is drastically reduced → friction drops → efficiency rises. NOT an increase in actual/effective area.
Word Association — 'ball bearing' → rolling contact → reduced friction/area. Exchange of Options — 'increased vs reduced area' is a classic setter-swap.
- 1Size of the sun at dusk
- 2Colour of the sun at dawn
- 3Moon being visible at dawn
- 4Twinkle of stars in the sky
- 5Polestar beingvisible in the sky
Which of the above are optical illusions?
Answer: atmospheric refraction causes —
- Larger-appearing sun at dusk ✓ (refraction near horizon magnifies)
- Reddish sun at dawn/dusk ✓ (Rayleigh scattering + refraction)
- Twinkling of stars ✓ (refraction by turbulent air layers)
- Moon visible at dawn depends on lunar phase, not refraction per se.
Atmospheric refraction is the common mechanism for most optical phenomena listed.
Word Association — 'atmospheric refraction' links all the listed phenomena. First Among Equals — the option covering ALL refraction-caused phenomena is broader and correct.
- 1Dispersion
- 2Refraction
- 3Internal reflection
Select the correct answer using the codes given below.
Answer (d): 1, 2 and 3 — all three phenomena are involved. Rainbow formation: sunlight enters a raindrop, REFRACTS on entering, undergoes TOTAL INTERNAL REFLECTION off the back of the droplet, then DISPERSES into component colours as it exits (refraction splits wavelengths). All three — dispersion, refraction, internal reflection — work together.
Science = Futuristic/Evolving — pick the BROADER option covering all three principles. First Among Equals — option (d) subsumes the others.
Answer (c): most root hairs are lost during transplantation. Root hairs (fine, single-cell projections of root epidermis) are the primary site of water/mineral absorption. They are extremely fragile and tear off when seedlings are uprooted → transplantation shock. Shoots don't absorb water; without root hairs, water uptake collapses → wilting/death.
Word Association — 'transplant' → physical disturbance → 'root hairs' (fragile structures). Over-Analysis → Paralysis — standard plant biology.
Answer: economic growth NECESSARILY occurs only if there is CAPITAL ACCUMULATION (or productivity rise) in country X itself — world-level progress, population growth, or external investment do not GUARANTEE growth in X. The option that identifies the NECESSARY internal driver is correct.
Extreme-Word Rule — strict logical necessity narrows the valid options. Over-Analysis → Paralysis — don't confuse 'sufficient' with 'necessary'.
- 1Viruses lack enzymes necessary for the generation of energy.
- 2Viruses can be cultured in any synthetic medium.
- 3Viruses are transmitted from one organism to another by biological vectors only.
Select the correct answer using the codes given below.
Answer: viruses — (i) lack enzymes necessary for ATP/energy generation (obligate intracellular parasites), (ii) can be cultured only in LIVING cells (not on artificial media like bacteria), (iii) some can be crystallised (e.g., TMV — first crystallised by W.M. Stanley 1935). Statements matching these virology facts are correct.
Science = Futuristic/Evolving — broad, correct claims about viral biology. Over-Analysis → Paralysis — standard textbook virology.
- 1Hard and waxy leaves
- 2Tiny leaves or no leaves
- 3Thorns instead of leaves
Select the correct answer using the codes given below.
Answer: desert leaf modifications — hard and waxy cuticle (reduces transpiration), tiny leaves or spines (reduce surface area), thick cuticle, sunken stomata — all CORRECT.
- Cactus: leaves reduced to spines; photosynthesis shifted to stem.
- Acacia, Euphorbia: tiny waxy leaves.
Statements describing these xerophytic adaptations are right.
Positive & Empowering Keywords — 'adaptation', 'conservation of water' — positive valence → correct. Hard to Verify / Disprove — general biology descriptions are hard to disprove.
Answer (a): Gravity is the strongest of the four — this is WRONG (the question asks for the NOT-correct statement). Gravity is the WEAKEST of the four fundamental forces — ~10^-39 of the strong nuclear force. But it acts over infinite range and dominates at astronomical scales. Correct picture: Strong > Electromagnetic > Weak > Gravity (by strength).
Extreme-Word Rule — exclusive claim → scrutinise. Positive Term → Positive Consequence / Negative Term → Negative Consequence — 'gravity = strongest' contradicts standard physics framing.
- 1It will enable us to understand as to why elementary particles have mass. technology to transferring matter from one point to another without traversing the physical space between them.
- 3It will enable us to create better fuels for nuclear fission.
Select the correct answer using the codes given below:
Answer (a): 1 only — Higgs boson discovery helps us understand why elementary particles have mass (via interaction with the Higgs field).
- Statement 2 (transporting matter without traversing space / 'teleportation') is SCIENCE FICTION, not physics.
- Statement 3 (better nuclear fission fuels) is unrelated to Higgs physics.
Only the mass-generation insight is the genuine significance.
Extreme-Word Rule — stmts with sci-fi leaps ('teleportation', 'unlimited potential') signal incorrectness when paired with real physics. Odd One Out — S1 (grounded physics) stands apart from S2–S3 (fantasy).
- 1resist drought and increase absorptive area
- 2tolerate extremes of PH
- 3Resist disease infestation
Select the correct answer using the codes given below:
Answer (d): 1, 2 and 3 — mycorrhizal symbiosis enables plants to (i) resist drought (fungal hyphae absorb water from wider soil volume), (ii) improve phosphorus and micronutrient uptake, (iii) tolerate heavy metals in polluted/degraded soils. All three mechanisms are well-documented in bioremediation literature.
Science = Futuristic/Evolving — biotech applications → broad, inclusive answers favoured. First Among Equals — 'all three' captures the full spectrum of mycorrhizal benefits. Positive & Empowering Keywords — 'rehabilitation', 'conservation', 'sustainability' → correct valence.
- 1The Prime Minister
- 2The Chairman, Finance Commission
- 3Ministers of the Union Cabinet
- 4Chief Ministers of the States
Select the correct answer using the codes given below:
Answer: NDC members = PM (Chairman) + all Union Cabinet Ministers + all CMs of States + Administrators of UTs + Members of the Planning Commission. Finance Commission Chairman is NOT a member of NDC.
- S1 CORRECT: PM is the Chairman.
- S2 WRONG: FC Chairman not in NDC.
- S3 CORRECT: Cabinet Ministers are members.
Exchange of Options — Finance Commission vs Planning Commission conflation is the classic trap — NDC is wired to Planning Commission, not FC. Contemporary Names — similar-sounding bodies used to confuse.
Answer (a): the total value of goods and services produced by the nationals of the country — this is GNP/National Income concept (by nationals, regardless of location). Distinguish: GDP (domestic territory, all producers) vs GNP (nationals, wherever). National Income = NNP at factor cost (by residents).
Exchange of Options — GDP-vs-GNP property swap is the classic trap — check 'domestic territory' vs 'nationals'. Word Association — 'National' income → 'nationals' (people), not 'domestic' (territory).
- 1Regional Rural Banks
- 2National Bank for Agriculture and Rural Development
- 3Land Development Banks
Select the correct anser using the codes given below:
Answer: Direct credit to rural households is provided by —
- RRBs ✓ directly retail agriculture and rural credit
- NABARD ✗ — apex refinance institution; does NOT lend directly to households, lends to RRBs/co-ops/banks
- Land Development Banks ✓ directly lend for long-term agri development
Statements identifying NABARD as a direct-lender are wrong.
Exchange of Options — NABARD's role (refinance, NOT direct retail) is a classic setter swap. Odd One Out — NABARD stands apart as an apex/refinance institution, not a retail lender.
