M: Don't worry. I'll be seeing him in an hour. I can ask him for his email address when I see him. W: That's very kind of you, Mr. Baker. What was said before this conversation?
Ans: W: What a memory I have! I did write down the mobile number on a sheet of paper when I answered the phone this morning, even that Mr. Smith's email address, and now it is nowhere to be found!

M: What do you think of the food today? W: You have to ask. About as terrible as usual, I'd say. M: You know, I think it's about time a group of us speak to some University officials about the quality of the food. W: Do you have a good idea? M: In my view, we had better get rid of the manager. W: Do you think you are the first to think of that? The problem is that the University doesn't want to change another manager. M: You mean you've been through this before? W: Yes, when I was a freshman, I once did that. I once wrote a letter to the Student Services Official and presented a petition signed by 200 students. M: What was his reaction? W: He asked me why all the other students didn't sign it as well. I told him we only had time for a sample, but I was sure almost all the students would have. M: Why was he so cool towards you? Isn't it a serious question? W: That manager has good friends in the University. You know family connections. What was said before this conversation?
Ans: W: I've just had my lunch at the cafeteria of our university.

W: I'll ask you if I ever need your advice. What was said before this conversation?
Ans: M: Do you know what you want to do when you finish your degree?

W: That's all right. John. My house is not that easy to find. But you know you wouldn't have gotten lost if you had a smart car. M: A smart car? What's that? W: I just read a magazine article about some new technology that can make a car smart. One device is a computerized map display and an artificial voice. You just enter the address for where you want to go and the voice will tell you how to get there,street by street. M: Hey, that's just like my brother. He never gets lost and he's always telling me the best route. So what else will the smart cars be able to do? W: Well, the article says there'll be a device with read-on warning systems that will warn drivers with a long signal if they're getting too close to other cars. And they will even put on brakes if the drivers don't. M: Tell me, Shelly. Will these cars be smart enough to fill themselves up with gas? W: Not by now. Why do you ask? M: I'm not late because I got lost. I'm late because I ran out of gas on the way over there. What was said before this conversation?
Ans: M: I'm sorry. I'm late.
