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.

Well, what have you been up to while I've been out shopping? ,M: Oh, nothing much. I've emailed a couple of friends. That's all.
(A) F: I am really sorry, I did not catch that. Would you slow down, please? (B) F: So you were sending e-mails at home just now, but why do you think blue is bad for me?
