Sentence Correction 36

    Mother dolphins whistle to their calves frequently after birth so that the calves will learn recognising their distinctive whistle.

    1. learn recognising their distinctive whistle.
    2. learn to recognise their distinctive whistle.
    3. will learn to recognise their distinctive whistle.
    4. learn to recognise their mother's distinctive whistle.

 

  • Correct Answer
    Choice (D)

Detailed Solution

The verb in the main clause is 'whistle', which is in simple present form. It is incorrect to pair this with the future tense verb 'will learn'. The simple present form, 'learn', is the one to be used instead.

The usage 'learn recognising' is incorrect. Only an infinitive can follow the verb 'learn'. The correct usage is 'learn to recognise'.

Finally, there is some ambiguity in the use of the pronoun 'their' in the given sentence. Does this pronoun refer to the mother dolphins or the calves? This is resolved by explicitly stating the noun: their mother's distinctive whistle.

Correct Answer: D
