Ex Input:
F: Dad, look at this friendship quiz. ,M: Why don't you try it? The first question, how often do you get in touch with your friends? ,F: Hmm... My friends aren't in the same secondary school as me, and I dislike ringing people up. I don't call my friends, even once a week. ,M: That means seldom. Secondly, how many friends can you talk with when you are upset? ,F: Oh, I can't think of any. I usually talk with you or mom when I feel sad. ,M: Poor Susan, you can't rely on us all the time. The last question, your friend wants to talk with you. Where would you have the talk? ,F: Well, we can't talk in the classroom. Maybe I would talk to her in a shopping center. We can talk and shop at the same time.
(A) M: I’m sorry, I didn’t catch that. Would you mind speaking more slowly? (B) M: All right. So you talk with your teacher in a shopping center. (C) M: All right. So you only talk with your friend in a classroom. (D) M: All right. So you only talk with your friend in a cafe.

Ex Output:

Ex Input:
M: Would you consider buying a self-driving car? ,F: I don't know. I guess I'd have to research a bit more about them before making that decision. ,M: It will probably be a while before we are able to buy them anyway. We might be seeing self-driving trucks on the road pretty soon, though. Google wants to change the commercial trucking industry. Right now, there are over 3 million truck drivers in the US, so adding self-driving trucks would likely take away a lot of jobs. But many drivers might still be able to accompany their trucks and get a full night's sleep in the process. ,F: Truck drivers cause a lot of accidents on the freeway, so I think I'd like to see self-driving trucks. It would make me feel safer on the road. ,M: Really? I think it might make me feel less safe. A human driver is much more likely to react quickly to something unexpected.
(A) F: I am not agree with you, I don't think they are safer. (B) F: I am really sorry, I did not catch that. Would you slow down, please? (C) F: I am not excited by their speed because I think they are not safe at all. (D) F: Are you serious? I don't understand why you feel scared by them.
