Example Input: M: Do you like this house? ,F: Yes, it's beautiful. ,M: It's perfect for us and the kids. ,F: 3 bedrooms, 3 bathrooms and a big backyard. ,M: And we can afford it!
(A) F: I’m sorry, I didn’t understand. Could you repeat a little louder, please? (B) F: This room is cheap, but it's too small. Let's have a look at others. (C) F: This office is big and beautiful, but we can't afford it. (D) F: I love it. This house is big and beautiful. We can go through the buying process.

Example Input: M: We've just moved into a new house. ,F: Really? Congratulations. ,M: Thank you. I think we want to buy a new television set. ,F: What kind of television do you want to buy? ,M: A color TV set, of course. But I'm not sure about the size. Maybe we should buy a big one. If we buy a small one, we might have to exchange it in a few years for a bigger one. That would be a waste of money. What's your opinion? ,F: In my opinion, I don't think it's necessary to buy a very big one.
(A) M: Why do you think we should get a small TV set but now a big one? (B) M: Yeah. We should buy a small TV set and change it in the future. (C) M: I agree with you. We should buy a big TV set instead of a small one. (D) M: Excuse me, could you repeat the question?
Example Output: A

Example Input: F: To start with, tell me about your education please. ,M: Alright. I shall graduate from Columbia University of foreign studies next year. I major in international trade. ,F: Are you single or married? ,M: I'm still single. I'd rather secure mycareer before settling down in a family. ,F: That's the kind of man we're looking for. Our promotion work needs much travel so do you mind many business trips? There will be 6 to 10 times traveling abroad a month. ,M: 6 to 10? Oh, that is indeed. ,F: OK. So I would say this work is indeed demanding. ,M: Err, I think it will be a challenge for me, but I am glad to take it. ,F: It has been pleasant talking with you. We'll notify you of our final decision within one week.
(A) M: Thanks. I am sure it is a relaxing and interesting job. (B) M: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (C) M: Thanks. The job is very relaxing and not demanding at all. (D) M: Thank you. I think it's a very challenging job for me.
