I haven't got a lot of time left ----- to send in my application forms.

A) within which
B) for which
C) in that
D) among them
E) to whom

According to the key A is correct. I agree with the key. Is it also correct if we leave blank, that is, to say "I haven't got a lot of time left to send in my application forms." To me it sounds fine. Thanks.

 

Yes, that would be the most natural way of saying it. A) doesn't sound good to me at all.

 

I agree completely -- leave it blank, much better. "Within which" sounds stilted.

 

Or belongs only in a grammar exercise for English leaners

 

Agreed, but I'd say "in which" would be perfectly fine.

 

I agree with Edinburgher on that -- "in which" is okay.
