Question

The given sentence is part of a passage. Fill in the blank with the correct form of the verb to complete the passage:

It _____(learn) to live under very hot and dry conditions.

• A. has learnt
• B. have learnt
• C. had learnt
• D. have been learning

Answer 1

Answer: (A), (C)

The correct options are
A has learnt
C had learnt

Option A and C are the correct answers because according to the statement, the organism now knows to live in extreme conditions because it had learnt in the past, and still has been learning, so it is correct to say that he had learnt or has learnt, both are correct.

Option B is incorrect because ‘have learnt’ is used for many organisms, as have is used along with a plural.

Option D is incorrect for the same reasons as option B.
