UPSC Prelims 2014— Question 30

Correct answer: Option A. Biosphere reserves are designed to reconcile biodiversity conservation with sustainable use and the continuation of traditional human communities and livelihoods. National parks generally have stricter restrictions on human use, while botanical gardens are ex-situ conservation facilities. Wildlife sanctuaries also permit regulated use but are not specifically the UNESCO-style integrated model implied by the question. Option A: Correct. This option is consistent with the governing fact or the valid combination identified in the question. The option reads: “biosphere reserves” 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: “botanical gardens” 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: “national parks” 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: “wildlife sanctuaries” 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.
