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: F: How often do you exercise? Do you play any sports? ,M: I do sports at school, that's about 3 hours every week. But that's all. I don't do any sports outside of school. ,F: Not even any cycling or walking? ,M: Very rarely. Because my mom takes me to school in the car.
(A) F: Yeah. It's good for your health to go to school by bike, but you enjoy playing sports outside of school, don't you? (B) F: Since you walk to school, you can do five hours of exercise a week. (C) F: I’m sorry, I don’t understand. Could you say it again? (D) F: Then you are so happy that your mother can drive you to school.

Example Input: F: Welcome, how may I help you today? ,M: I'd like a pizza, please. ,F: Then you'll be happy to hear that today. All our pizzas are on sale 2 for one. ,M: You're right, that is great! ,F: What size would you like? ,M: A medium one would be perfect. Thank you. ,F: Which kind you want? ,M: I like seafood on my pizza. ,F: We have 2 seafood pizzas, fish and crab. ,M: Crab sounds good, today.
