Example Input: F: So David, you don't like sports. ,M: Well, I like sports, but I'm just not keen on sports programs. You know, I would usually rather watch a movie or some kind of history program. ,F: Oh, ok, so you're into history? ,M: Oh yes, I like studying the history of the countries that I have visited. It makes it more interesting when I go sightseeing. ,F: Ok, which countries have you visited? ,M: I been over a good bit of Europe. Ah, Mexico, Peru. I spent almost a year in Egypt and I went to Israel, Jordan and now I'm here in Japan. I've been in Japan for a year and a half, and while I have been here, I visited Korea for about a week.
(A) F: Yes, a week or so in Egypt is too short. But it amazes me that you've never been to Europe. (B) F: You mean you stayed in Korea for one year and went to Egypt for one and a half year? Cool. (C) F: So you spend one year in Egypt and another one in Japan? It seems you really like travel. (D) F: I’m sorry, I didn’t understand. Could you repeat a little louder, please?
Example Output: D

Example Input: F: In the end, we chose David. He wasn't ideal but there was nobody else who we interviewed that we liked. ,M: But we really regret it now. He's really antisocial. He stays in his room all day reading. ,F: True, it's like he feels superior to us. ,M: He doesn't leave his dirty clothes around. That's one good thing I suppose. ,F: And the food he makes is disgusting. I'd like to share meals, but with him, it's impossible. He only eats frozen rubbish and then sometimes he takes my food without asking which is annoying.
(A) M: You didn't like David when we interviewed because he enjoys smoking. (B) M: Although he is good at making food, he is always cruel to animals. (C) M: You'd like to share meals with him, but you hate that he sometimes eats without permission. (D) M: I am afraid I did not quite catch what you were saying. Please repeat it.
