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: 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.
Example Output: B

Example Input: M: International Film Club. ,F: Hello, I'd like some information about the club, please? ,M: Certainly, first of all, you must be over 15. Is that OK? ,F: Yes, that's fine. I'm 16, are you open on Sunday. ,M: I'm sorry, we aren't. When we started we opened from Tuesday to Friday, but now we open from Monday to Saturday. We get more people now.
(A) F: So we can not go there on Sunday because it is closed. (B) F: You mean the club open on Sunday now. (C) F: I'm sorry, I didn't understand. Could you repeat a little louder, please? (D) F: It is a pity that the club is closed on Monday.

(A) M: Do you need a ride home in case the oranges and apples are too heavy? (B) M: I suggest you list sweets and apples on the list so that you won't forget it. (C) M: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (D) M: Would it help if I come with you to fetch the vegetables and apples?
