Question

?When __________ you last use the computer

have


did


does


has

Answer 1

When did you last use the computer?

It's correct because, have wouldn't fit right. If the sentence read, "When have you last used the computer," it would, but it doesn't.

Does, doesn't make since either, nor does has.

Answer 2

Answer: The answer would be did!

Step-by-step explanation:

? when HAVE you last use the computer

? when DID you last use the computer

? when DOES you last use the computer

For have to make sense, it would have to say USED instead of USE.

(which would make sense to mix up!)

as you can see, DID is the only one who make sense!
