The answer is:
M: Excuse me, could you please tell me the way to the city library?
input question: W: Good morning. I wonder if you can help. I've lost my coat. M: Where did you lose it, madam? W: Er... I left it on a bus yesterday morning. M: Can you describe it? Is it a raincoat? W: No. It's a long white overcoat. It's got a belt, and one of those thick furry collars that keep your ears warm. It's a very nice coat, actually. M: Hmm. I'm afraid we haven't got anything like that, madam. Sorry. But, may I have your name and your telephone number? We'll contact you as soon as we've got it. What was said before this conversation????

Q: M: In an hour. W: Can you come much earlier? What was said before this conversation?
A: W: When will you be back?
[Q]: M: Sure. But I don't have any information about the recent films. What about you? W: Well, my workmate tells me that Harry Potter and the Sorcerer's Stone will be on. M: What's that? W: I don't know. It is said that kids like it a lot. M: Perhaps you can take our son there. It's boring for me to sit there for two hours. W: Oh, you're that kind of man. Um, a violent film called The Most Wanted will also be on at the same time. Maybe you can come with us. M: That's a clever idea. I like American films very much. We can go to the same cinema and come home together, but watch different films. What was said before this conversation?
