input question: F: Thanks, Dad! What was said before this conversation????
output answer: M: Here is a concert ticket for you. I hope you will like it.
M: Isn't that far away? W: Not really. If you take the No. 3 bus, you can get there in ten minutes. And if volleyball doesn't interest you, they've got a huge indoor swimming pool, a weight room, and indoor tracks. It's a great place to meet people. M: Now that you mentioned it, it would be nice to get away from the computer center for a change, and I really should get some more exercise. Working up a sweat in a ball game or the weight room would be nice. I've got so fat. W: Look at me -You're not the only one. In high school I had a lot more time to do sports activities. Now what little spare time you have must be used in doing exercise. At least the club is open until 12 pm. M: I guess it's worth a visit. Did you say you're going tomorrow night? W: Yeah. M: OK, I'll come, too. How about meeting me in front of the cinema at eight, and we'll catch the bus there. W: Sure, see you then. What was said before this conversation?

Answer: W: Are you busy tomorrow night? I'm going over to the Workers Club for volleyball if you'd like to come along.
Q: W: You have a point. Air pollution is a problem. But not letting people drive on certain days is a bad idea. People have to go to work by car. M: I'm afraid I don't agree with you there. Reducing air pollution is really important. People are so used to driving that they don't think about ways to do things. If we stop them from driving on certain days, maybe they could think of new ways to get around. W: I see your point. But I still think it wouldn't be possible to stop people from driving.

Problem: Given the question: M: I'm sorry, Mary. But I came home quite late yesterday about half past nine in the evening. Jim and Betty invited me to go for a picnic. W: Oh, how lovely, Tom! And did you like the picnic? M: Yes, I liked it very much. W: When did you leave, Tom? M: Jim and Betty came in their car about ten o'clock in the morning, and we left soon afterwards. W: And where did you go for the picnic? M: We went to National Park. W: Oh, it's lovely in National Park at this time of the year. M: Yes, and the sun shone all day. W: There's a river in National Park; did you have your lunch near the river? M: Yes, we had lunch near the river. Then, after lunch, we went for a walk along the river. Then we climbed up to the top of a hill, and looked at the beautiful view. W: What did you do then, Tom? M: Well, we went back to the car, and we drove to another part of National Park, and we had afternoon tea there. Then we started to drive home. W: Oh, you left early! M: Yes, Mary. But it took a long time to reach home because there was a lot of traffic on the road. W: Well, that was a lovely day's outing. M: Yes, I had a very good time. What was said before this conversation?
