Example Input: F: Here we go. Now, Terry, you were saying that you went from Vancouver to San Diego. How many days did that take? ,M: Um, the total trip took 42 days but that included one day on the bus up and then one day on the bus back.
(A) F: I am afraid I did not quite catch what you were saying. Please repeat it. (B) F: It just took you 42 days from New York to San Diego? That's amazing. (C) F: It is worthy for you to travel in China for 40 days, it a wonderful country. (D) F: The 36 days stay in Japan must be interesting, right? Tell me more about that.

Example Input: M: Can you give me some information about getting to the Town Center? ,F: Well, you can drive, but the parking is difficult. It will be quite expensive if you stay there all day. ,M: Yes, we're thinking of going to look around some of the shops, and look at the wall around the city. So we'll probably be there most of the day. ,F: In that case, you'd better take a taxi or the bus. ,M: How much does taking a taxi cost? ,F: It will be about 12 pounds. Actually I'd say it's around 16 pounds, because fares have increased recently. We can book it for you in our travel agency and it will pick you up outside. It only takes about 10 minutes. ,M: Right, I see. What about taking the bus? How much is that? ,F: It's only 2 pounds per person, it's not far from here. You go out of here, turn right on Oak Tree Avenue, and it's about a 5 minute walk down the road. The bus ride is about 15 minutes.
(A) M: We'll take the bus as the bus ride is only about 5 minutes. (B) M: We'll go there by bus as the bus ride is only about 15 minutes. (C) M: Excuse me, could you repeat the question? (D) M: Although we need to walk at least 10 minutes, we'll go there by bus as the bus ride is only about 15 minutes.
Example Output: B

Example Input: M: So, what should we take? ,F: I'm going to take my guitar. ,M: Great! And I'm going to take my CD player. ,F: You'd better take lots of music. We've got a 4 hour drive with just mom and dad. ,M: Yeah. I don't know why they want to go camping anyway. Boring. ,F: It sure is and we're missing the baseball game on TV tonight. ,M: Don't remind me. Hey, do you think I should take these? ,F: Yeah,why not?
(A) M: I'm sorry, I don't understand. Could you say it again? (B) M: You should prepare well for your baseball game. (C) M: We're missing the football game on TV tonight in order to prepare our camping. (D) M: We will enjoy our camping.
