Task: Dialogue Generation
Input (English): F: Excuse me, I'm doing research on bus service, but I get you to answer a few questions. It won't take long. ,M: OK. I'd like to help. ,F: Thanks. How often do you take a bus, every day, less than once a week or somewhere in between? ,M: I go to school by bus so it's usually twice daily, line 4. ,F: I see. Could you rate it service if 1 is poor, 2 is fair and 3 is good? Which number would you choose? ,M: I would say 2. The drivers are nice, the buses are clean and the seats are comfortable. But it's sometimes unreliable. There should be a bus every 10 minutes, but yesterday morning, I waited almost 20 minutes before the bus came and was almost late for school.
(A) F: So, you mean although the drivers are not nice, you feel the bus service is good? (B) F: So, as the buses are dirty and the seats are not comfortable, you feel the bus service is poor? (C) F: Really? You mean you would say 4? And you feel the bus service is fair? (D) F: I’m sorry, I don’t understand. Could you say it again?
Output (English): D
