Example Input: F: Hello, XYZ Accounting. ,M: Hello, could I speak to Brian Robinson, please? ,F: Mister Robinson is in a meeting right now. Can I put you through to his voicemail? ,M: No thanks, I'll try back later. I just have a couple of quick questions about my tax return.
(A) F: Oh, you are calling only to pay taxes. Maybe I can help you. (B) F: I’m sorry, I didn’t understand. Could you repeat a little louder, please? (C) F: So you are calling only to get information from me, right? (D) F: Maybe I can give you the information that you need.
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: M: Darling, why are you so worried? ,F: Oh, I just talked to our daughter Susan's teacher. She told me that Susan often doesn't finish her homework. And when she does, well, the quality is often very poor.
(A) M: Take your time. Our students are the best. The quality of Susan's homework is often very good. (B) M: I am sorry. You spoke so rapidly that I did not catch the meaning of what you said. Could you repeat that? (C) M: It's okay. Our daughter will be fine, although the quality if often very poor. (D) M: Not a big deal. Susan's teacher didn't talk to you, right?
