In this task you are given a small conversation between two persons and 4 options on how the conversation should continue. Your job is to choose the most reasonable option. The conversation and the options are separated by a newline character. Each dialogue in the conversation are separated by a comma. F and M indicate female and male, respectively.

Example Input: M: How do you usually get to work in the morning? ,F: I try to ride my bike most of the time. Of course, when I'm running late, I take the subway. ,M: I always seem to be 5 or 10 minutes late for everything. I drive to work everyday. So if the traffic is bad, I have to think of a new way to apologize to my boss for being late. ,F: Does your boss yell at you if you're late? ,M: No, not really. He knows that I live far away. I stay late whenever I don't make it on time in the morning and it probably helps that I earned a fair amount of money for the company year after year. ,F: Have you ever considered moving into the city to be closer to your job?
(A) M: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (B) M: I always work overtime. (C) M: Are you always work overtime. I never work over time. (D) M: I will be fined if I late all the time.
Example Output: B

Example Input: F: Oh, there is nothing better than an ice cold glass of ice water on a hot day. ,M: You know, cold water always gives me stomachaches. ,F: Really? I've never had that problem. I've been drinking ice water since I was little. ,M: When I was a small boy, my grandmother never let my mom give me anything other than warm water. ,F: Even in the summer? ,M: Yes, every once in a while my dad would take me to get some ice cream, but my grandmother was never happy about that. I think it was the sugar that she didn't like.
(A) F: Your grandmother tell you to drink only cold water on hot days? (B) F: I'm sorry, I didn't catch that. Would you mind speaking more slowly? (C) F: Drinking warm water in summer sounds healthy, but I can't do it. (D) F: You only have something other than water in summer, like ice cream.
Example Output: C

Example Input: F: Excuse me, I'm doing research on bus service, but I get you to answer a few questions. It won't take long. ,M: OK. I'd like to help. ,F: Thanks. How often do you take a bus, every day, less than once a week or somewhere in between? ,M: I go to school by bus so it's usually twice daily, line 4. ,F: I see. Could you rate it service if 1 is poor, 2 is fair and 3 is good? Which number would you choose? ,M: I would say 2. The drivers are nice, the buses are clean and the seats are comfortable. But it's sometimes unreliable. There should be a bus every 10 minutes, but yesterday morning, I waited almost 20 minutes before the bus came and was almost late for school. ,F: Oh, that's too bad. Do you have some suggestions for the bus company? ,M: Try to have the buses arrive on time of course, and um, there can be a map on the bus. You know, some passengers cannot use the guidebook very well.
(A) F: So, you mean as the drivers are not nice, the drivers should be more polite? (B) F: So, you mean the buses should be more punctual and there can be a radio on the bus? (C) F: I didn't hear you. Please could you tell me again? (D) F: So, you mean the bus is never unreliable but the seats should be more comfortable?
