French question, help quickly please.?

If we have a comprehension and in the comprehension, there are two people talking to each other (conversation) or one person is asking another person questions and the other person is replying.. is that a reportage or an enquete? One teacher told me that this is reportage and the other told me that this is enquete.. I have a French exam tomorrow and I need to check which one is correct in case something like that came in the comprehension in tomorrow's exam.
