I am sure I would have regretted it if I ________ to take the job.

a.would agree
b.would have agreed*
c. did agree
d.had agreed*

I am rather puzzled at this. Please help.

Yes, right.

Oh alright then, I get it now. Thanks!

There are two ‘would have’ verb phrases in the sentence. Which one will you change?

Oh, so then it would be d since there is already a 'would have' in the sentence?

would have agreed

it's NOT d. I think it is "Had Agreed"

Had agreed

1-a

a b b b c c c d
