A、A lecture. B、His office. C、A party. D、A meeting. CWhere has the man probably just escaped from?

M: Whew. The disco wasn’t bad but I’m glad to escape from the noise. Aren’t you?
W: Ummmmm.
M: Mary, I’d forgotten. You’ve got a letter. Now where did I put it? There it is. Under the gas bill.
W: Oh, from my brother.
M: Good. How many brothers have you got?
W: Only one.
M: Name?
W: Mark.
M: Older or younger?
W: Much older.
M: How much?
W: Five years.
M: Get on all right?
W: Yes, all right.
M: Tell me about Mark. You must have a lot in common. Such as problems.
W: Well, when I have a real problem I usually discuss it with Mark.
M: And what is a real problem?
W: Money is one. But Mark never minds helping me out.
M: You say money is one problem. I suppose you mean there are others.
W. Well, yes. Of course there are. Friends and possessions. He knows who my friends are and I know who his friends are. But when we meet we hardly ever speak. His friends aren’t interested in talking to my friends. And my friends think his friends are boring and patronising.
M: Go on, Mary. You mentioned possessions. What about possessions?
W: I can never find my favorite cassettes. Mark and his friends keep borrowing them. I suppose Mark has a point when he says be can’t find his calculator. I use it whenever I can find it.
M: So...if you were in real trouble, who would you con- tact first?
W: Mark, of course.
