Daily Current Affairs Quiz Prelims Practice 2027
- It was notified by the Ministry of Power under the Energy Conservation (Amendment) Act, 2022.
- Grid Controller of India Limited (GCIL) acts as the administrator of the scheme and issues Carbon Credit Certificates (CCCs).
- Central Electricity Regulatory Commission (CERC) regulates the trading of CCCs on power exchanges.
- The Indian Carbon Market (ICM) operates as an absolute cap-and-trade system, similar to the EU ETS.
Statements 1 and 3 are correct — CCTS was notified by the Ministry of Power under the Energy Conservation (Amendment) Act, 2022, and CERC regulates the trading of CCCs on power exchanges. Statement 2 is the key trap — GCIL is the registry, not the administrator; BEE (Bureau of Energy Efficiency) administers the scheme and issues CCCs. Statement 4 is incorrect — India's ICM is an intensity-based baseline-and-credit system, not an absolute cap-and-trade like the EU ETS.
- India's nuclear warheads (2026) — ~190
- India's global military expenditure rank (2025) — 4th (after US, China, Russia)
- India's share of global arms imports (2021–25) — 8.2%, 2nd largest after Ukraine
- NPT non-signatory nuclear states — India, Pakistan, Israel
Pairs 1, 3, and 4 are correctly matched — India had ~190 nuclear warheads in 2026, its share of global arms imports was 8.2% making it 2nd largest after Ukraine (2021–25), and India, Pakistan, and Israel are the three NPT non-signatory nuclear states. Pair 2 is the trap — India ranks 5th in global military expenditure, not 4th; the correct order is US, China, Russia, then Germany (which surged post-Ukraine), and then India.
- NFHS-6 covers data from approximately 6.8 lakh households across all States and UTs including Manipur.
- Spousal violence against women declined from 29.3% (NFHS-5) to 22.3% in NFHS-6.
- Anaemia prevalence data was dropped from NFHS-6 because NFHS-5 had shown improvement across all States and UTs.
- The Diet and Biomarkers Survey, launched at ICMR-NIN Hyderabad, uses venous blood sampling and is proposed as an alternative source for anaemia tracking.
Statements 2 and 4 are correct — spousal violence declined from 29.3% to 22.3%, and the Diet and Biomarkers Survey at ICMR-NIN Hyderabad uses venous blood sampling as a proposed alternative for anaemia tracking. Statement 1 is incorrect — Manipur is excluded from NFHS-6 coverage. Statement 3 is a deliberate inversion — NFHS-5 actually showed worsening anaemia across 28 States/UTs; the official justification for dropping the indicator was a methodological concern about the capillary finger-prick method, not an improvement in data.
- Orobanche is an obligate root holoparasite that attaches to mustard roots via haustoria and can cause up to 50% yield loss in severely affected fields.
- IMI-resistant mustard hybrids are transgenic (GM) crops developed by inserting a foreign ALS gene from a herbicide-resistant bacterium.
- Orobanche seeds can remain viable in the soil for up to 20 years, making eradication through crop rotation alone very slow.
- Prof. Deepak Pental's primary concern is that continuous use of a single herbicide mode of action will select for IMI-resistant Orobanche populations over time.
Statements 1, 3, and 4 are correct — Orobanche attaches via haustoria causing up to 50% yield loss, its seeds remain viable for up to 20 years making crop-rotation-only eradication very slow, and Prof. Pental's concern is that single-mode herbicide reliance will select for IMI-resistant Orobanche populations. Statement 2 is the central trap — IMI-resistant hybrids are developed through mutation breeding, in which a naturally occurring ALS enzyme mutation is selected; no foreign DNA is inserted, making them non-GMO and non-transgenic.
- The Santha-Vazirani Limit (1986) proved that classical post-processing cannot eliminate bias from a weakly random source.
- In the ETH Zürich experiment, a Bell violation score of 2.271 — above the classical limit of 2.0 — confirmed quantum entanglement governed the randomness.
- The ETH Zürich protocol is currently deployable at commercial scale, producing random bits at rates comparable to existing quantum random number generators.
- Post-quantum cryptography algorithms such as CRYSTALS-Kyber are designed to protect data against quantum computer attacks — a threat that better randomness alone cannot address.
Statements 1, 2, and 4 are correct — the Santha-Vazirani Limit (1986) established that classical post-processing cannot remove bias from a weak random source; the ETH Zürich experiment recorded a Bell violation score of 2.271, above the classical limit of 2.0, confirming quantum entanglement; and CRYSTALS-Kyber-type post-quantum algorithms address quantum computer attacks, which randomness quality improvements alone cannot counter. Statement 3 is the trap — the ETH Zürich protocol produces only ~1,400 bits/second versus ~1 billion bits/second from commercial quantum RNGs, making it a research-grade proof-of-concept, not a deployable system.
