Example Input: M: Lily, I can't catch up with the English teacher very well. ,F: What's the problem? ,M: You are quite good at English.

What's that? ,F: This kind of school is good at helping people to improve their English. ,M: Is that different from our school's English course? ,F: Yes. Before you start your training, they will test you on your English first. ,M: Then? ,F: Then they will recommend you the class that suits you. ,M: Really? How good can my English get there? ,F: You see how well I am doing. I studied there, too. ,M: Alright. I'll tell my father about it.
(A) F: I am really sorry, I did not catch that. Would you slow down, please? (B) F: Yes. I think you should go to the English schools. It's really helpful. (C) F: Why are you going to the English school? Although it's helpful to me, it doesn't suit you. (D) F: I don't know you but I find the additional course in English schools is easy but not helpful.

Do you think you can help me out? ,M: Sure, what's this project about? ,F: Well, I should interview someone that I admire about their jobs. ,M: Well, I am an expert when it comes to my job. Accounting is a respectable job and one that I am always happy to talk about. ,F: Dad, I know how much you love your job. It isn't that I don't admire you. But what I was hoping actually was that you could speak to Mr. Chung, your diving friend, and see if he would agree to an interview. Diving for a living sounds cool. ,M: I see. That's a great idea. You know how I really dislike talking about myself again and again for too long. Let me give David Chung a call right now and find out. ,F: Thanks, dad. I know this will be a wonderful project.
