M: I don’t know. It sucks!
W:(13)But I really don’t want to cancel our trip. All of us have already made our plan reservations!
M: I can try to call the travel agency, maybe they can refund our money. But before we do anything, we need to talk with our professors.
W: You think they’ll excuse us from class?
M: Probably not.(14)But I was talking to Jim this morning and he said that one of his professors told him that they could make up the class at a different time.
W: Wow! That’s great! Which professor was it?
M: I don’t know. But we’re going to have to speak to all of them anyway.
W: Why didn’t they add extra days at the end of this semester?
M:(15)Because the graduation date cannot be changed.
W: I was just really looking forward to this vacation. The idea of the sun and the beach!
M: Me too. Oh, look, there’s Prof. Webster!
W: Come on, let’s go talk to her!
