Example Input: M: Thank you for calling the Hillside Gallery. How can I help you? ,F: Hello. Is there a photography exhibition this weekend? ,M: Yes, there is. ,F: How much is the ticket? ,M: Tickets for the gallery are 10 pounds and half price for children, but this includes the painting exhibitions, too. If you only want to see the photography exhibition, it's 7 pounds per person, with half price for children, too. ,F: The gallery's on Flower Street, isn't it? ,M: No, we moved to a different building last year. Our present address is 25 Gardenia Road. It's opposite to the Town Square. ,F: Oh, I see. Does the number 25 bus go by it? ,M: Yes, but I suggest you not take a bus or drive here. You will be stuck in a traffic jam at weekends on this street. The underground is easy and fast.
(A) F: Sure, I will take the bus there as you suggested since it's faster and cheaper. (B) F: I hate traffic jam. In that case, I shall take the underground to go to your gallery. (C) F: I’m sorry, I didn’t catch that. Would you mind speaking more slowly? (D) F: So you think it's better driving there since neither bus nor subway goes there.
Example Output: B

Example Input: F: Hello, Mr.Smith. This is Janet Bush. ,M: Hello, Miss Bush. ,F: I'm afraid I'm going to be late for our appointment. My friend was supposed to pick me up from the airport, but she just called me and said she is stuck in traffic downtown so she won't be here right now. It's 11 now, so there is no way I'm going to the restaurant at 11:30 as we planned. I wonder if we could reschedule our appointment to sometime this afternoon
(A) M: Yes, we had planned to meet at 11:30 a.m. Since you can't make it, let's reschedule our appointment at 1:00 pm. (B) M: Have you forgot it? We had planned to meet at about 11 a.m. Since you can't make it, let's reschedule our appointment at 1:00 pm. (C) M: I am sorry. You spoke so rapidly that I did not catch the meaning of what you said. Could you repeat that? (D) M: OK, let's postpone our meeting for half an hour. Can we meet at 2 p.m?
Example Output: A

Example Input: F: I'm so sorry I'm late, Mister Stone. ,M: I think I did ask Miss Jones to inform everyone that the meeting started at 11:00 sharp, now 10 minutes have passed already.
(A) F: I’m sorry, I didn’t understand. Could you repeat a little louder, please? (B) F: It's 11:15 now, so we still have 15 minutes before the meeting. (C) F: We've been told to start the meeting at 11:10 and it's exactly 11:10. (D) F: I know it's 11:10 and I'm late for the meeting, but I want to explain.
