Hi,
In the quiz, there were 4 choices given. I think I can translate them all, except one is puzzling me.
Paul aurait dû partir plus tôt. MEANS Paul should have left earlier
Paul aurait pu partir plus tôt MEANS Paul could have left earlier
Paul devrait partir plus tôt MEANS Paul should leave earlier.
If those are right, then that leave this one: What's the right translation for "'Paul had had to leave earlier?"
