UPSC Prelims 2021— Question 86

R2 stands for Responsible Recycling and is associated with responsible practices in the electronics recycling/reuse industry. The R2 Standard addresses environmental, health, safety, security and data-related aspects of electronics recycling. It is not a Ramsar wetland-management instrument, agricultural cultivation standard or a generic environmental-impact-assessment tool. The final answer-key position for Set C identifies option A as the correct option. Option A — environmentally responsible practices in electronics recycling industry — is correct because it is the alternative that matches the constitutional, historical, geographical, scientific or economic principle established above. Option B — ecological management of Wetlands of International Importance under the Ramsar Convention — is not correct because it does not satisfy the specific condition tested in the question; it represents an alternative that is contradicted, incomplete, or less precise than the accepted answer. Option C — sustainable practices in the cultivation of agricultural crops in degraded lands — is not correct because it does not satisfy the specific condition tested in the question; it represents an alternative that is contradicted, incomplete, or less precise than the accepted answer. Option D — Environmental Impact Assessment in the exploitation of natural resources — is not correct because it does not satisfy the specific condition tested in the question; it represents an alternative that is contradicted, incomplete, or less precise than the accepted answer. For PYQ interpretation, the distinction between the correct alternative and merely related facts is important. UPSC often places plausible distractors beside the precise statement that matches the underlying rule, chronology, definition or empirical relationship. The answer should therefore be read against the exact wording of the question rather than against a broadly related fact.
