Q:

Improve the given sentence if necessary.

We can go out whenever we choose to, isn’t it?

A) can’t we B) are we not
C) don’t we D) No improvement
 
Answer & Explanation Answer: A) can’t we

Explanation:

The question tag ‘isn’t it’ needs to be replaced with ‘can’t we’. This is because the sentence and the question tag must be in the same tense and the same pronoun is to be used in the question tag. Thus, the correct formation would be, ‘we can go out whenever we choose to, can’t we?’
