Example Input: M: My program is a course in automotive repair. We teach people from the age of 16 through to adults. We're located on a high school campus. It's vocational, which means that we train people in specific skills that they could use in a job. ,F: I like classes, because it's more like the real world than when you're sitting there reading a textbook, not knowing what you're going to be using it for. ,M: Today's a work day. So when I go back into the shop, I have all my students working on a project. First, Jack is going to get the air tools out and jack up a car. He's going to take a tyre off that car with the air impact. Every student is an individual that comes into my program. All of them think that they're going to be able to fix their own cars. They all have it as a goal that they're going to get out of the program. And then, as part of my introduction to the class, I'll let them know some of the other things that they'll all get, which include consumer understanding of how the car works.
(A) F: I’m sorry, I didn’t catch that. Would you mind speaking more slowly? (B) F: Uh, I think people always want to keep themselves fit, that's why they will join the fitness class. (C) F: Well, I understand why people want to teach the course, because people usually want more interaction in this literature course. (D) F: Alright, so that's why people always want to build a garage in their house, they just want to fix their own cars.
Example Output: A

Example Input: F: We're having a small lunch party next Friday. Would you like to come? ,M: I'd love to, but I'm afraid I'll be away at a meeting in Brussels. And please email me a copy of the report we just talked about.
(A) F: Okay, since you decide to go to the party, we'll wait for you. (B) F: All right, and I hope your business trip in Paris goes well. (C) F: Excuse me, could you repeat the question? (D) F: Well, and don't forget to send me a report by E-mail after coming to the next Friday's party.
