Tidy up the garage and clean up the backyard. ,M: She doesn't say which we should do first. ,F: Hey, we're not robots. We can make our own plan as long as everything gets done. Read the weather report in the newspaper. ,M: Em, sunny today, cloudy tonight, probably heavy rain tomorrow. Well, that makes it easy. We work outside today and inside tomorrow.
(A) F: Cloudy tonight? That's not a good sign for tomorrow. (B) F: I'm sorry, I don't understand. Could you say it again? (C) F: Although it is cloudy tonight, I believe tomorrow will be a sunny day. (D) F: It is a pity that it will rain tonight.
Example Output: A

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 Output: C

Example Input: F: What are you going to do tonight? ,M: Oh, I'm going to stay at home and study. My final exam is coming up next week. ,F: Is it going to be difficult? ,M: It will be harder than the mid-term exam. I'm sure. ,F: Was the mid-term exam difficult? ,M: It was the most difficult exam that I'd ever had. ,F: Then maybe this one will be easier.
(A) M: You might be right. The midterm exam was quite easy and the final one may be the same. (B) M: I'm sorry, I don't understand. Could you say it again? (C) M: I didn't review for my midterm, which was difficult, so I'll study hard for next month's final. (D) M: No really. The midterm was already the most tough exam for me. I worry about the final.
