Question

Fill in the blank with a suitable auxiliary verb:
His eye sight is weak. He ______ to wear glasses.

• A. Had
• B. Does
• C. Has
• D. Was

Answer 1

Answer: (C)

Has

The given sentence is a sentence which expresses an obligation in the present tense. In such a sentence, the appropriate form of the auxiliary 'have' is used. As the subject 'he' is in the third person singular form, the appropriate form of the auxiliary is 'has'. Hence, option C is the correct answer.

Option A: The auxiliary 'had' is used to express an obligation in the past tense. Example: 'He had to wear glasses'. However, the use of the word, 'is' in the first sentence suggests that the sentence is in the present tense. So, the second sentence cannot be in past tense. Hence, this option is incorrect.

Option B: The auxiliary, 'does' is used either (a) to form negative and interrogative sentences or (b) emphasise the affirmative nature of a sentence. Neither of these cases is applicable to the given sentence. Hence, option B is incorrect.

Option D: The use of the word, 'is' in the first sentence suggests that this sentence is in the present tense. So, the second sentence cannot be in past tense. However, the auxiliary 'was' is used in past tense. Hence, this option is incorrect.
