Student or Learner
I can't find any reason why D is answering?
why we can't use C?
Did the teacher give details about how ................. for this test.
a. do we prepare
b. can we prepare
d. to prepare
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
B would work if it said we can prepare. All of the options are close, but only D is correct.
