A、Because of the possibility of bad weather. B、Because of the faculty’s contracts. C、Because of the summer schedule of classes.

M: Vicky! Have you heard the news?
W: No, Sam. What do you mean?
M: You know all the classes we’ve missed because of the snow?
W: Uh oh ....
M: Yup-we’re going to have to make them up and the dean says it will have to be during spring break.
W: Sam! We have our-vacation all set! What are we going to do? Do the others know?
M: I don’t know but I certainly can’t afford to miss five days of classes this semester, with that week I was sick ....
W: But I really don’t want to cancel our trip. All of us have already made our plane reservations!
M: I can try to call the travel agency; maybe they can refund our money. But before we do anything we need to speak with our professors.
W: You think they’ll excuse us from class?
M: Probably not. But I was talking to Mark 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 the semester before summer classes?
M: Because of the graduation date, which can’t be changed.
W: Are other colleges around here doing the same thing?
M: I would imagine set---it’s been such a bad winter and we’ve missed too many classes. We do really need to make them up.
W: I know, I know. I was just really looking forward to this vacation. The idea of the sun and the beach!
M: Oh look, there’s Professor Miller right now!
W: Come on, let’s go talk to her!
