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: F: I have been having a lot of trouble managing my time. I always forget my test and homework, due dates and I can never find the right notes I need. I heard that you're really organized. Do you think you could help me? ,M: Sure, I'd be happy to help. First of all, you need to get a planner, like this one. It's a small notebook in calendar where you can write down all the important dates you need to remember. Then you should create some sort of filing system to organize your notes. I use different colored files to keep the papers for my different classes.
(A) F: I’m sorry, I didn’t catch that. Would you mind speaking more slowly? (B) F: Really? You mean you'd not be happy to help me? Oh, we are classmates. (C) F: So, you mean first I don't need to get a planner? Okay, I will take your advice, teacher. (D) F: Oh, you are the considerate classmate. I will take your advice. Thank you.
Example Output: D

Example Input: M: Wow, this dance is surely cool. There are so many people here. Ah, what's your name? ,F: Susan, Susan Dors. You really don't know who I am? You sit behind me in geography class. ,M: Oh yeah, you're right. I guess I'm just used to looking at the back of your head, not your face. ,F: Are you OK? You're so nervous. ,M: I'm sorry for my strange behavior. I don't know why I pretended I didn't know who you were. I just didn't know how to start the conversation. ,F: That's OK. It's refreshing to talk to somebody who's actually honest for once, so do you like this music? ,M: Not really. I prefer rock and roll mostly. But I like to listen to blues when I'm alone. Anything but this pop stuff. ,F: Oh my gosh. I totally agree. I thought I was the only one.
(A) M: Excuse me, could you repeat the question? (B) M: You are not alone. By the way, the pop playing at the dance sounds awful. (C) M: No, you are not the only. Anyway, I like the blues playing at the dance. (D) M: But I really don't like the rock and roll playing at the dance.
