UPSC Prelims 2014— Question 56

Correct answer: Option A. Chechnya is a republic of the Russian Federation. Darfur is a region of Sudan, not Mali, and the Swat Valley is in Pakistan, not Iraq. Hence only the first pair is correctly matched. Option A: Correct. This option is consistent with the governing fact or the valid combination identified in the question. The option reads: “1 only” Option B: Incorrect. This option does not match the verified answer because its proposition, location, institution, sequence, or combination conflicts with the relevant fact tested in the question. The option reads: “2 and 3 only” Option C: Incorrect. This option does not match the verified answer because its proposition, location, institution, sequence, or combination conflicts with the relevant fact tested in the question. The option reads: “1 and 3 only” Option D: Incorrect. This option does not match the verified answer because its proposition, location, institution, sequence, or combination conflicts with the relevant fact tested in the question. The option reads: “1, 2 and 3” The key Prelims lesson is to test each proposition independently before selecting the combination. Where the question uses words such as 'only', 'all', 'none', 'always' or a precise institutional/geographical association, a single inaccurate component is sufficient to eliminate the option. The answer recorded here follows the official answer key for the question-paper series represented by the uploaded source and has been cross-checked against an independent published key.
