M: My history professor says I should think about a job in politics, but I don't think I'd make a good politician. ,F: Why not? ,M: You know me. I'm not good at dealing with people and politicians have to work with people all the time. ,F: That's true. So what do you think you want to do? ,M: I think I will be a good artist. I love painting pictures. ,F: That reminds me of a problem I'm having. You know my parents have a restaurant, right? They want me to be the manager. ,M: And you want to? ,F: No way. A restaurant manager has to manage other people. It would be terrible. I'm too disorganized. Honestly, I want to be a teacher because I like working with kids and I'm good at it.
(A) M: That's true, I remember you are really good at working with kids. (B) M: I am sorry. You spoke so rapidly that I did not catch the meaning of what you said. Could you repeat that?

F: Oh, I'm terribly sorry, sir. I didn't see you stop. ,M: Well, that was probably because you were talking on your mobile phone. ,F: Sir, I, ah, don't know what you're talking about. I was just looking out the window. ,M: Young lady, I saw you in my mirror. You had the phone up to your ear the whole time. ,F: No, I was just doing my hair. ,M: Listen, I'm not stupid, OK? When the police get here, they're going to check your phone and see that you made a call at the time of the accident. You're in big trouble. ,F: No, please don't call them. My father will kill me. Look, here's my insurance card. They'll pay for the damage to your car.
(A) M: I'm sorry, I don't understand. Could you say it again? (B) M: You drive this time? I am sure that you will damage my car. (C) M: It's too late. They are on their way. And the insurance company will estimate the damage on my car then. (D) M: Why did you call the police? The security camera has proved that I didn't damage your car.
