Example Input: F: Here are your cold dishes, sir. ,M: Thank you. I wonder why it Chinese dinner always starts with cold dishes instead of hot courses. Could you explain that to me? ,F: Certainly, sir. It's a custom in our country to serve cold dishes first as they have been prepared before hand. ,M: Oh, I see. The chefs in your country are just in the habit of preparing cold dishes first. ,F: I'm afraid that's not exactly right, sir. Chinese people usually regard the dinner party as an occasion for a friendly chat. ,M: Yes, I quite agree. But what does that have to do with serving cold dishes first? ,F: Well, people usually talk more and eat less at the beginning of the dinner. Therefore, if hot courses were served they would get cold very quickly. ,M: I see, but the problem is that I'm already full when it comes to the wonderful hot courses. And I often miss the chances to enjoy many Chinese dishes.
(A) F: Excuse me, could you repeat the question? (B) F: It's just a habit of Chinese chefs. (C) F: Hot dishes would get cold during the chat. (D) F: Hot dishes would get cold during the chat, so people chat less at the beginning of the dinner.

Example Input: M: Welcome back to your student union radio station. I'm with Catherine, who just successfully climbed the Great Mountain, Mont Blanc. Actually, she once did. The same climb in 2007. Catherine, was it easier the second time around? ,F: In many ways. They were totally different experiences. The first time I went as part of an organized group. We took 4 days to reach the top. This year, I decided to go alone with just one overnight stop, actually you're never really alone. It's all been crowded up there. The first climb, was quite difficult is the weather was very changeable, and we found ourselves climbing in very cold windy conditions. The weather this time was wonderful. Plus. I spent a few days before in chamonix and got myself more used to the height. If it's certainly made it easier, you can also achieve the same thing by climbing some of the smaller mountains first.
(A) M: You are used to climbing mountains in a group, and you never climb alone. (B) M: I’m sorry, I didn’t understand. Could you repeat a little louder, please? (C) M: You are so brave that you successfully climbed the Mont Blanc on your own. (D) M: You climb mountains with a guide? No wonder you just took 2 days to reach the top.
Example Output: C

Example Input: M: I was thinking of starting my own business. ,F: What kind? ,M: I know you wanted me to take over your restaurant business, but to be honest, I can't stand working in the food industry. ,F: Don't worry, I knew that along time ago. ,M: I thought maybe you and dad could lend me some money to open a skateboarding shop. ,F: That's possible, do you have a business plan? ,M: Not in writing, but I've thought of all the details. ,F: So what would you sell? ,M: We'd sell skateboards, clothing, shoes and other kinds of things. ,F: What would make your shop different from all the others? ,M: I thought we could make own T shirts. ,F: It sounds OK to me, but you'll have to talk to your father about this too.
