UPSC Prelims 2014— Question 91

Correct answer: Option B. The first BRIC summit was held in Yekaterinburg, Russia, in 2009, not Rio de Janeiro. South Africa joined the grouping in 2010, becoming the fifth member and the last entrant before the later expansion. Hence only statement 2 is correct. Option A: 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 only” Option B: Correct. This option is consistent with the governing fact or the valid combination identified in the question. The option reads: “2 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: “Both 1 and 2” 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: “Neither 1 nor 2” 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.
