Problem: M: I'll call you when it's ready. But it shouldn't take longer than a week. What was said before this conversation?

A: W: How long will it take you to fix my watch?
Problem: Given the question: M: Not much. I started exercising. W: Trying to get in shape? M: Yeah, and I need to start improving my health. W: Me, too. What are you doing besides exercising? M: That's about all. W: I think if you eat better, it will also help a lot. M: Sleep is important, too. I heard people who sleep an average of eight hours a day have less health problems. W: Looks like there are a lot of things to do to stay healthy. M: True. But I think it is worth it. When you get older, you want to be healthy and active. W: Absolutely.

The answer is:
W: Hi, Mike. What have you been up to?
input question: W: Yes, I just got here yesterday. And you? M: I'm a native. W: Oh, really? Everyone else I've met so far has been a tourist like us. I was beginning to think that there were no natives. M: Well. San Francisco has a lot of different ethnic groups so you might think you're seeing a lot of foreigners. But actually, the city has a population of about 700 000. W: What are the different ethnic groups? M: Web, after whites, the largest one is blacks. W: I thought it was Chinese. M: It's true that San Francisco has the largest Chinese community outside of Asia. But there are many more blacks here than Chinese. W: That's interesting. Don't most of the Chinese people live in China-town? M: Well, no, they live all over the city, but China-town is definitely the center of Chinese culture here. That's where you'll find the best Chinese restaurants, bookstores, art, theaters, things like that. W: What about the Japanese? Doesn't San Francisco have a large Japanese population too? M: No, actually there are only about 12 000 Japanese people here, but we do have an area called "Japan-town" that has Japanese restaurants and bookstores. W: You seem to know a lot about this city. M: Well, most San Franciscans think their city is pretty special. We like to talk about it. Besides, I teach ethnic history at the university here. W: No wonder you know so much!

Answer: W: I heard you received the top grade on all five exams this semester.
Q: W: Move? What do you mean? M: Move to a new city. I'm thinking of getting another job. W: But why? What's the matter with the one you have? M: I don't have a good future in the job I have. Besides, I think it would be nice to move to a warmer climate. I'm tired of shoveling snow all winter. W: Where is this new job? M: In California. There won't be any snow to shovel there, and we can go to the beach all the year round. W: That sounds pretty good, but what kind of job is it? M: I would be the Director of Research for a big drug company near Los Angeles. I'd get a big raise in salary. W: That sounds terribly exciting. But how about the children? Will they like moving? M: Why not? California has many beautiful new schools, and Fred can go skiing up in the mountains. W: What about Paula? I'm sure she won't want to leave all her friends. M: Oh, she can make new ones out there. People are very friendly out west. W: I hope so. But, I'll certainly hate to leave this house. We've lived here so long. M: Well, maybe I won't get the job. I have to fly out there for an interview next week. W: You know, I must have known you were thinking about getting a new job. Last night I dreamed we were moving. What was said before this conversation?
A: M: How would you like to move?
[Q]: M: Yes. I have to do a research paper for history. There's a major book that I need, but I can't find it. W: Did you try the card list? M: Yes, but it's not there. W: Well, if it's a recent book, it won't be in the card list. All information about books since 1995 is in the computer. I advise you to try that. M: No wonder! This book is published in 1998. W: All you have to do is to type in the title or the writer's name. M: Do you mean it will tell me whether the book is out or not? W: Yes, it will. It will also give you the due date if it is out. If the book is in the library, it will tell you where you can find the book. What was said before this conversation?
