A、A poetry book. B、A history book. C、A mystery book. D、Some children stories. C男士说，你的诗歌书可能让你富有，但我想这本75美分的侦探小说更值得买。C正确。

W: You enjoy going through secondhand bookstores, don’t you? It’s interesting to see what people used to enjoy reading. Did you see this old book of children’s stories?
M: Some of these books aren’t so old, though. See? This mystery was published only six years ago. It cost seventy-five cents.
W: Hey! Look at this!
M: What? Are you getting interested in nineteenth-century poetry all of a sudden?
W: Well, look at the inscription. Someone gave this book as a present, and wrote a note on the inside of the front cover. It’s dated 1893. Maybe it’s worth something.
M: Everything on that shelf is worth fifty cents.
W:[23]But if this is the signature of someone who is well known, it might bring a lot more. I hear William Shakespeare’s signature is worth about a million dollars.
M: Oh? I can hardly read what that one says. Who wrote it?
W: The name looks like "Harold Dobson". Maybe "Dobbins"? Wasn’t he a politician or something? I’m going to buy this book and see if I can find a name like that in the library.
M: Good luck. Your poetry book may make you rich, but I’ll bet my seventy-five-cent mystery is a better buy.
W: Anyway, I will take it. Let’s see other books. Is there anything you think is very suitable for my brother to read?
M: Which kind of book does your brother like?
W: Oh, it’s really a question for me. Maybe I should make a call to ask him about that.
M: You’d better check than guess.
