Ex Input:
M: Doctor Wilson, can I talk to you for a minute? ,F: Sure, Fred. What is it? ,M: I'm worried about my grade in your English Class. I really want an A, but. ,F: I see. Well, it might be hard for you to get an A. So far, you have a B average. You would need a 97 or 98 on your final exam to get an A. Do you think you can get that higher score? ,M: Probably not. The problem is that I have to have a B average in all the subjects to get the prize from our government. Otherwise, I'll have to find a part time job. I'm afraid it is difficult for me to put all my heart in my study if I have to work in my spare time. I'll probably get an A in history and a B in maths, but I'll get a C in chemistry.
(A) F: I am really sorry, I did not catch that. Would you slow down, please? (B) F: Sounds great that you can get A in history and maths. Happy for you! (C) F: You must have put in a lot of effort to get A in maths and chemistry! (D) F: Don' t be sad! At least you can get an A in history. Everything will be alright!

(A) M: I’m sorry, I don’t understand. Could you say it again? (B) M: That would be great. Make it 5:10. (C) M: Since you want 10 past 5, let's meet then. (D) M: Sure, 5:40 is ok.

Ex Input:
M: Hi, Jane. Welcome back. How was the west coast? ,F: Terrific. I had a wonderful time. It was really nice to get away from the city for a while. ,M: What did you think of Los Angeles? ,F: It was alright. I liked it better than I thought I would. It's very clean and spacious and it's got a lot of trees. The problem is transportation. The bus service is terrible and of course, they don't have any subway, so it's a little difficult to get around. We had to rent a car. ,M: And was the weather good? ,F: Oh yes, it was nice and warm in Los Angelus and cool, but comfortable in San Francisco.
(A) M: You mean, with hardly any tree in Los Angeles, it's very noisy there. (B) M: I didn't expect it to be so hot in LA. Luckily, you could take subway. (C) M: I am sorry. You spoke so rapidly that I did not catch the meaning of what you said. Could you repeat that? (D) M: No subway and terrible bus service? No wonder you don't like LA at all.
