Consider the following statements. Which one of the following is correct in respect of the above statements?
- 1.Statement-I: India, despite having uranium deposits, depends on coal for most of its electricity production.
- 2.Statement-II: Uranium, enriched to the extent of at least 60%, is required for the production of electricity.
- (a)Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
- (b)Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I
- (c)Statement-I is correct but Statement-II is incorrect
- (d)Statement-I is incorrect but Statement-II is correct
Answer: (c) Statement-I is correct but Statement-II is incorrect
India’s nuclear capacity is only about 3% of its electricity, despite having uranium reserves — coal supplies most of the country’s power, so Statement-I holds. But civil power reactors run on natural or low-enriched uranium, well under 20% U-235; 60%+ enrichment is weapons-grade territory, not something electricity generation needs.

Consider the following statements. Which one of the following is correct in respect of the above statements?
- 1.Statement-I: Interest income from the deposits in Infrastructure Investment Trusts (InvITs) distributed to their investors is exempted from tax, but the dividend is taxable.
- 2.Statement-II: InvITs are recognized as borrowers under the ‘Securitization and Reconstruction of Financial Assets and Enforcement of Security Interest Act, 2002’.
- (a)Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
- (b)Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I
- (c)Statement-I is correct but Statement-II is incorrect
- (d)Statement-I is incorrect but Statement-II is correct
Answer: (b) Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I
Prior to Budget 2023 changes, interest-income distributions from InvITs were tax-exempt to investors, while dividend distributions were taxable at slab rate. Separately, a 2021 Finance Act amendment recognised InvITs as ‘borrowers’ under the SARFAESI Act, 2002 — correct, but unrelated to the tax treatment.

- (a)Only one
- (b)Only two
- (c)Only three
- (d)All four
Answer: (c) Only three
Brand recognition, intellectual property, and a client mailing list are intangible investments. They have no physical form. Their value comes from reputation, legal rights, or customer relationships, not physical output. Inventory is the odd one out. It is a tangible asset instead — physical stock of raw materials, work-in-progress, or finished goods, held for production or sale.

With reference to the role of biofilters in Recirculating Aquaculture System, consider the following statements. How many of the statements given above are correct?
- 1.Biofilters provide waste treatment by removing uneaten fish feed.
- 2.Biofilters convert ammonia present in fish waste to nitrate.
- 3.Biofilters increase phosphorus as nutrient for fish in water.
- (a)Only one
- (b)Only two
- (c)All three
- (d)None
Answer: (a) Only one
Only statement 2 is correct. Statement 1 is wrong because uneaten fish feed is a solid waste, removed by mechanical filtration — drum filters, microscreens and settling tanks — not by the biofilter. Statement 2 is correct: the biofilter carries out nitrification, oxidising ammonia to nitrite and then to nitrate. Statement 3 is wrong because biofilters add no phosphorus. Phosphorus enters only through the feed, and it accumulates precisely because nitrifying biofilters do not remove it.

Consider the following statements. Which one of the following is correct in respect of the above statements?
- 1.Statement-I: The soil in tropical rain forests is rich in nutrients.
- 2.Statement-II: The high temperature and moisture of tropical rain forests cause dead organic matter in the soil to decompose quickly.
- (a)Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
- (b)Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I
- (c)Statement-I is correct but Statement-II is incorrect
- (d)Statement-I is incorrect but Statement-II is correct
Answer: (d) Statement-I is incorrect but Statement-II is correct
Tropical rainforest soil is actually nutrient-poor, not rich — most nutrients are locked in living plants, not the soil. Statement-II is correct: high temperature and moisture make organic matter decompose quickly, but plants reabsorb those nutrients almost immediately.

Consider the following statements. Which one of the following is correct in respect of the above statements?
- 1.Statement-I: The temperature contrast between continents and oceans is greater during summer than in winter.
- 2.Statement-II: The specific heat of water is more than that of land surface.
- (a)Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
- (b)Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I
- (c)Statement-I is correct but Statement-II is incorrect
- (d)Statement-I is incorrect but Statement-II is correct
Answer: (d) Statement-I is incorrect but Statement-II is correct
Statement-II is correct: water’s specific heat is higher than land’s, so oceans warm and cool more slowly than land. This makes Statement-I incorrect. Land-ocean temperature contrast is actually greater in winter, not summer. In winter, land cools fast while the ocean stays relatively warm, widening the gap. In summer, land heats fast but the ocean lags behind, narrowing the gap compared to winter.

Consider the following statements. Which of the statements given above is/are correct?
- 1.In a seismograph, P waves are recorded earlier than S waves.
- 2.In P waves, the individual particles vibrate to and fro in the direction of wave propagation whereas in S waves, the particles vibrate up and down at right angles to the direction of wave propagation.
- (a)1 only
- (b)2 only
- (c)Both 1 and 2
- (d)Neither 1 nor 2
Answer: (c) Both 1 and 2
Both statements are correct. P (Primary) waves are the fastest seismic waves, so they always reach a seismograph before S (Secondary) waves. P waves are compressional, so particles vibrate back and forth along the wave’s own direction of travel. S waves are shear waves, so their particles vibrate at right angles to that direction instead.
