Example Input: F: Adam, I heard you want to get in shape. Why not join the club I am in? ,M: Is it far from our neighborhood? ,F: No, it's just 10 minutes away from here by bike. ,M: What do you do there? ,F: Well, I often start out running for about half an hour and then I get in the swimming pool for an hour. ,M: I really like swimming. It's a good way to lose weight, isn't it? ,F: Oh, it certainly is. I was 135 pounds when I joined the club. Now I weigh just 120 pounds, and I'm sure I'll manage to lose another 10 pounds by the end of July. ,M: That's amazing. Perhaps I'll go and have a look at your club tonight.
(A) F: Are you going to lose weight by cycling? The club is only 10 minutes' walk from here. (B) F: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (C) F: Although the club is 30 minutes away from here by bike, why are you going to lose weight by running? (D) F: Great, then you're probably going to lose weight by swimming.
Example Output: D

Example Input: M: Good morning, Susan. Did you sleep well last night? ,F: I fell asleep right away, didn't wake up once and didn't have any bad dreams. ,M: Great! You look much more relaxed today. ,F: Much better. But I'm still worried about something. ,M: What's that? ,F: Well, I have to drive to school for a meeting this morning and I'm afraid I may get stuck in the rush hour traffic, and I will be pretty upset. ,M: Don't worry! Just breathe deeply when that happens. ,F: OK, I'll try that.
(A) M: Really? You'll not try that? Oh, as you worry about your difficulty in breathing, I think you should try it. (B) M: Yeah, it is very useful to try to breathe deeply as you worry about the rush-hour traffic this morning. (C) M: I didn't hear you. Please could you tell me again? (D) M: Well, as you have to drive to company for a meeting this morning, I am not surprised that you worry about the rush-hour traffic.
Example Output: B

Example Input: M: Do you think people's moods are affected by the climate they live in? ,F: Well, I think there's certainly something in it. Because when the weather is hot, I easily lose my temper, but when it's cooler I feel much calmer. And if it's raining, I always feel sad.
(A) M: Why do you feel angry when it's hot? (B) M: Excuse me, could you repeat the question? (C) M: Why do you feel sad when it's hot? (D) M: Why don't you feel angry but sad when it's hot?
