A、That the library opens at 8:00. B、 That no one else has read the articles. C、That none of the material he needs is available.

W: Can I help you?
M: Yes, I’d like to read some articles that are on reserve about British culture.
W: Professor Grand’s class?
M: That’s right. How could you know?
W: Let’s just say you are not the first person coming in asking for those articles.
M: Oh, well, seeing as how I haven’t read any of them yet, it doesn’t really matter which one you give me first.
W: I’m afraid I can’t give you any of them at the moment. They’ve all been checked out.
M: You’re joking, all of them?
W: Every month. I’ve asked professor Grand twice already to bring in additional copies of the articles, but no sooner do I place them on the shelves than they are gone. See that girl in the black sweater? She’s been waiting for half an hour for those same articles to be returned.
M: And here’s me. I went out of my way to free out the whole afternoon to read.
W: I’m sorry, but there is not a whole lot I can do about it. All I can suggest is that you come in first thing to morrow morning and try again. We open at eight.
