Example Input: M: Diana, can you give me a hand? I'm supposed to place all these new products in the display case, but they'll never fit. ,F: Yeah, I see what you mean. But did Miss Harper mean to put them all on display, or just one of each as a sample for the customers to see? ,M: Oh, I get it! So maybe I should just select a single example of each model instead of one of each color for each model. ,F: Check with Miss Harper first. But in my opinion, that's the only way you'll be able to do it.
(A) M: I manage to put them all in the case, but I can't find Ms.Harper to check. (B) M: It's all because of the limited space. Daisy, throw away these products. (C) M: Well, it's all because there isn't enough room for all the new products. (D) M: I’m sorry, I didn’t catch that. Would you mind speaking more slowly?
Example Output: C

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: M: You look sleepy this morning, Beverly. Did you go to bed late last night? ,F: No. I slept through my alarm this morning, so I didn't get a chance to shower.
(A) M: I’m sorry, I don’t understand. Could you say it again? (B) M: You woke up late because you went to bed late last night. (C) M: Why did you work late last night? (D) M: So you woke up late, right?
