output: W: Something is wrong with our TV.
Please answer this: M: I've just taken my chemistry exam and I'm pretty sure I failed it. I don't know where the professor got some of those questions. I don't see how in the world I could pass. W: Come on now. You've been doing very well all year long. It's not very likely you'd suddenly forget everything. Oh, by the way, have the physics grades been posted yet? M: I didn't go and look. I was so busy worrying about chemistry. Do you think there's any possibility of me passing for the year if I fail the final? W: Sure there is. It's the average that is important. Come on. Just relax. How about having a cup of coffee? What was said before this conversation?

Answer: W: What's the matter, Paul? You look terrible.
Problem: M: Thanks, same to you. Doing anything exciting? W: No, not really. We were thinking of going to the beach, but I don't think Martin is well enough to go. So he will probably stay in and watch TV. And I'll plant the rose bushes I bought yesterday. What was said before this conversation?

A: W: Bye, Mark, have a nice weekend.
Problem: Given the question: W: Pubs in England are friendly and warm places where you can have a drink and usually a simple meal. M: What kind of drinks do people get? W: You can get wine and beer in most pubs. Many also serve coffee. You go to the counter to order and pay for your drinks. M: When do people go to the pubs? W: Pubs are not open all day. They can decide when to open. Most are open for 3 or 4 hours at lunchtime and again from about 6:00 p.m. to 11:00 p.m. In busy areas, pubs may stay open from 11:00 a.m. to 11:00 p.m. Are there pubs in China? M: Yes. Most of the customers are young people. They like to hang out with their friends after work and have fun. W: It is against the law in England to go into a pub if you are under the age of l4. So many pubs provide a special room for children. What was said before this conversation?

input question: W: Yes. I paid a visit to London and attended a summer course in English. M: Wow. It sounds so good. How long did you stay there? W: Well, I went there on July 5th and came back on August 15th. M: What about the course? W: I think the course was well organized. The teachers were nice. They taught us to listen, speak, read and write in English, but it mostly focused on speaking. One interesting thing I found was that the English classes were different from ours because they were very free. You can sit anywhere you like in the classroom. You can ask the teacher questions at any time during the class, and you are welcome to share your ideas with the classmates and teachers. I really enjoy this kind of class. M: How interesting! Maybe our teachers should try that. What was said before this conversation????
