UPSC Prelims 2024— Question 94

The correct answer is option (A). In January, in the Northern Hemisphere, land cools faster than oceans, so isotherms generally bend southward over continents and northward over oceans. The first statement therefore correctly describes the broad pattern. The Gulf Stream and North Atlantic Drift are warm currents, not cold currents, although they do help push isotherms northward. Because Statement 2 incorrectly calls them cold currents, only Statement 1 is correct. The key to this question is to distinguish the exact constitutional provision, factual association, scientific principle, or current-affairs detail being tested from statements that are partly true but incomplete or incorrectly framed. UPSC often makes the distractors plausible by changing one institutional role, date, classification, geographic association, or causal relationship. Option A — “1 only” is correct. It matches the established fact described above and gives the complete combination or identification required by the question. Option B — “2 only” is incorrect. It does not match the established fact or contains the incorrect combination, institution, relationship, classification, or proposition identified in the explanation above. Choosing it would therefore introduce a factual error or omit a necessary element. Option C — “Both 1 and 2” is incorrect. It does not match the established fact or contains the incorrect combination, institution, relationship, classification, or proposition identified in the explanation above. Choosing it would therefore introduce a factual error or omit a necessary element. Option D — “Neither 1 nor 2” is incorrect. It does not match the established fact or contains the incorrect combination, institution, relationship, classification, or proposition identified in the explanation above. Choosing it would therefore introduce a factual error or omit a necessary element. For examination purposes, the safest approach is to verify each statement independently before looking at the answer-code combination. This is particularly important in statement-based questions, because one false clause makes an entire combination wrong. In factual questions, compare the defining characteristic asked in the stem with each alternative rather than relying on superficial familiarity.
