Problem: M: Yes, I'm very sorry. W: Why did you get here so late? M: I watched TV till very late last night. W: What was on? M: It was an exc iting football match. France against Germany. When the France were about to win... So, I got up late and didn't have breakfast and left home in a hurry. W: Did you catch the train? M: No, I called for a taxi. There were a lot of cars and buses on the highway. Unfortunately an accident happened. Then, there was a traffic jam. I was very anxious... W: What happened after that? M: The police came and solved the problem. I waited for a long time. When I got to the office, it was already 10 o'clock. W: I hope that you won't be late again. Otherwise I will fire you.

Problem: Given the question: M: I was just taking a break. What's up? W: We'll have a math test next Monday, so I thought you'd be studying for it and maybe I can study with you. M: But I can't believe you are coming to me. I mean you do know what I got on the last test, don't you? W: Yeah, I know. You told me, but I thought two heads might be better than one. M: Well, that's a nice idea. But I wish I knew the person in our class who got a hundred on the last test. She even didn't miss any question, you know! Umm, was it Elizabeth? W: Oh yeah, Elizabeth! She is a good friend of mine. I think she'd be a big help to us right now. Why don't we give her a call? M: What? At this hour? It's already ten thirty. It's too late. W: But you know she owes me a big favor. Let's at least give her a call and see what she says. Maybe going over some of the problems with us would also help her review the material. M: You're right. Anyway, it's worth a try. What was said before this conversation?
