Question

Fill in the blank using a demonstrative adjective:
What was ________ noise?

• A. this
• B. that
• C. these
• D. those

Answer 1

The correct option is B that

'Noise' is singular.

'Was' explains that the given interrogatory sentence is in the simple past tense.

Option A - 'This' is used with a singular subject that is near to us. As 'noise' is not near or not heard in the present, we can't use 'this' here. Thus option A is incorrect.

Option C - 'These' is used with a plural subject that is near to us. However, 'noise' is singular. Thus option C is incorrect.

Option D - 'Those' is used with a plural subject that is far to us. However, 'noise' is singular. Thus option D is incorrect.

Option B - 'That' is used with a singular subject that is far to us. As 'noise' was heard in the past, we can use 'that'. Thus option B is the correct answer.

'What was that noise?'
