UPSC Prelims 2023 GS Paper I · Q12 of 98 Environment & Ecology medium

Consider the following statements : Statement-I : Marsupials are not naturally found in India. Statement-II : Marsupials can thrive only in montane grasslands with no predators. Which one of the following is correct in respect of the above statements?

  1. (a) Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
  2. (b) Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I
  3. (c) Statement-I is correct but Statement-II is incorrect ✓ UPSC's answer
  4. (d) Statement-I is incorrect but Statement-II is correct

Why the answer is (c)

• Marsupials — pouched mammals such as kangaroos, koalas, wombats and opossums — occur naturally only in Australasia and the Americas; none is native to India, so Statement-I is correct.

• Statement-II is incorrect: marsupials occupy a huge range of habitats, from Australian deserts and tropical rainforests to American woodlands, and coexist with predators such as dingoes, eagles and pythons; they are not confined to predator-free montane grasslands.

• Their absence from India is a matter of biogeography — they evolved in Gondwanan lands that separated before India joined Asia — not of habitat.

• Hence Statement-I is correct but Statement-II is incorrect, option (c).

Why the other options are wrong

(a) Both Statement-I and Statement-II are correct and Statement-II is the correct explanation…
Statement-II is wrong: marsupials live in many habitats with predators.
(b) Both Statement-I and Statement-II are correct and Statement-II is not the correct…
Statement-II is wrong, so both cannot be correct.
(d) Statement-I is incorrect but Statement-II is correct
Statement-I is correct: no marsupial is native to India.
