Example Input: F: The children have been playing in the mountains for a long time. Why haven't they come back? I am really worried about them. ,M: Look at the sky. Black clouds are gathering and strong winds are blowing. It seems a heavy rain will fall soon. ,F: They haven't brought anything to protect themselves. They will be caught in the rain I think. ,M: Don't be worried too much about them. Anyhow, they're old enough now. They ought to be able to take care of themselves. ,F: I'm afraid they will catch a cold if they are caught in the rain. You see it's a little cold now.
(A) M: I’m sorry, I don’t understand. Could you say it again? (B) M: Don't worry, they will not be caught in the heavy rain. It is sunny outside. (C) M: You can ask them if they pass the exams directly, they are in their bedrooms. (D) M: Don't worry about the children, they won't be caught in the heavy rain.
Example Output: D

Example Input: M: Would you consider buying a self-driving car? ,F: I don't know. I guess I'd have to research a bit more about them before making that decision. ,M: It will probably be a while before we are able to buy them anyway. We might be seeing self-driving trucks on the road pretty soon, though. Google wants to change the commercial trucking industry. Right now, there are over 3 million truck drivers in the US, so adding self-driving trucks would likely take away a lot of jobs. But many drivers might still be able to accompany their trucks and get a full night's sleep in the process. ,F: Truck drivers cause a lot of accidents on the freeway, so I think I'd like to see self-driving trucks. It would make me feel safer on the road. ,M: Really? I think it might make me feel less safe. A human driver is much more likely to react quickly to something unexpected.
(A) F: I am not agree with you, I don't think they are safer. (B) F: I am really sorry, I did not catch that. Would you slow down, please? (C) F: I am not excited by their speed because I think they are not safe at all. (D) F: Are you serious? I don't understand why you feel scared by them.
Example Output: D

Example Input: F: Mr. Sharp, thank you for giving me this interview. So, my first question is, are you happy with your life? ,M: Am I happy? You may know you are the first person to have asked me this question directly. The others dared not because they were afraid I might say yes. They wanted me to say no so that they could make up stories about me. ,F: What kind of stories? ,M: Brian Sharpe, author of over 100 historical novels, lives in a lonely house 30 miles away from Sydney. But is he happy? (?). ,F: Is that why you have refused many interviews? ,M: I'm tired of being told that I must be unhappy because I'm rich and successful. I'm not unhappy.
(A) F: I’m sorry, I didn’t catch that. Would you mind speaking more slowly? (B) F: Why do these people make up successful stories for you even though you are not? (C) F: IYou care too much about your privacy, you should show your real life instead of making up stories. (D) F: Why are hiding my questions? Are they too direct to you to answer?
Example Output:
