Please answer this: W: What's your problem? M: I just can not find the right place here. I've never been here before. W: You must be a freshman. What do you want anyway? M: I want to find a book that I need for my term paper, but I cannot find it anywhere. W: The library has five reading rooms. You may try the General Reading Room. You can find almost all the books there. But you can not take the book out of the reading room. M: It doesn't matter. I just want to refer to it for some figures. Where is it? W: Go out of this building, cross the sports field, and you will see a white house. The General Reading Room is inside it. M: No wonder! It's not here! Thank you very much. W: My pleasure!

A: M: I heard you took a trip to Mexico last month. How did you like it?
Problem: Given the question: M: Some of these books aren't so old, though. See? This novel 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 plays all of a sudden? W: No. Look at the signature. Someone gave this book as a present, and wrote a note on the inside of the front cover. It's dated 1856. Maybe it's worth something. M: Everything on that shelf is worth fifty cents. W: 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 the one says. Who wrote it? W: The name looks like "Harold Dickinson". 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 book of plays may make you rich, but I'll bet my seventy-five cents novel is a better buy. What was said before this conversation?
