UPSC Prelims 2020— Question 55

This question tests desert national park. The key concept is: Desert National Park in Rajasthan extends across Jaisalmer and Barmer districts and is a major habitat of the Great Indian Bustard. Human habitation and pastoral use occur in the landscape, so the statement claiming no human habitation is incorrect. Hence statements 1 and 3 are correct. The verified answer for the uploaded Set-B paper is option C. Option A — 1 and 2 only: This is not the correct option. The option does not match the verified combination or conclusion. The decisive point is the distinction explained above: Desert National Park in Rajasthan extends across Jaisalmer and Barmer districts and is a major habitat of the Great Indian Bustard. Human habitation and pastoral use occur in the landscape, so the statement claiming no human habitation is incorrect. Hence statements 1 and 3 are correct. Therefore this alternative should be eliminated even if part of its wording appears plausible in isolation. Option B — 2 and 3 only: This is not the correct option.

For UPSC-style elimination, first identify the exact proposition being tested, then evaluate each statement independently before comparing the answer codes. Avoid treating a broad or absolute statement as correct merely because its general theme is familiar. The precise qualifiers in the question—such as 'all', 'only', 'cannot', 'largest', 'always' or a specific institutional role—often determine the answer. On that basis, option C is the verified answer.
