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.

Example Input: M: Oh, hello, I like the holiday that mentioned Whales, was it whale watching? ,F: Oh yes, it's very popular. ,M: How long does it last? ,F: 2 days. We take up to 15 people on this tour, though we usually run it with just 12 or 13. ,M: And when is the next tour going? ,F: Umm, there is one in 3 weeks time on April the eighteenth and then we don't have another one until June the second. ,M: Is there anything else included in the tour? ,F: Oh, there are a lot of things. If you don't want to do the whale watching cruise, your guide will take anyone who is interested. In a Bush walk through the National Park near the hotel. There is no extra charge for that or on a fishing trip, which is an extra $12 I think. There is also a reptile park in town, which costs more or less the same. ,M: Well, I think I prefer Wales to Snakes. ,F: Oh, the hotel has badminton courts, and table tennis tables. But I think you'll be interested in going bowling there. ,M: Bowling? That sounds good. That's my favorite, thanks for the information.
(A) F: You are welcome. I know that you like to play table tennis the most. (B) F: You are welcome. You are free to go bowling whenever you want. (C) F: Excuse me, could you repeat the question? (D) F: Sure. I know that you love playing badminton the best.
