Cool. I like this Pop Quiz. For once I can try and answer without people telling me "if you don't know it just shut up" LOL
Well, let's see...
1_ E; F; H; I
2_ I
E=I did the right ting to go; F=H= I went; I=hadn't I gone it would have been better.
I think A=didn't go; B=If I had gone I would have done the right thing; C=I didn't go!(isn't this past negative of imperative? my head doesn't really clicks on this one); D=I should have gone (as in I missed the chance to it); G=I wanted to go, but...; J=I should have gone, but (as in I had planned to go but); K=can't recognize that form.
??? Well, let's see the score
P.S. Oops just thought about it. If someone else wants to answer go ahead. Don't think my answers are correct, coz great chances are out there that they are not LOL.
