Ex Input:
M: Doctor Wilson, can I talk to you for a minute? ,F: Sure, Fred. What is it? ,M: I'm worried about my grade in your English Class. I really want an A, but. ,F: I see. Well, it might be hard for you to get an A. So far, you have a B average. You would need a 97 or 98 on your final exam to get an A. Do you think you can get that higher score? ,M: Probably not. The problem is that I have to have a B average in all the subjects to get the prize from our government. Otherwise, I'll have to find a part time job. I'm afraid it is difficult for me to put all my heart in my study if I have to work in my spare time. I'll probably get an A in history and a B in maths, but I'll get a C in chemistry.
(A) F: I am really sorry, I did not catch that. Would you slow down, please? (B) F: Sounds great that you can get A in history and maths. Happy for you! (C) F: You must have put in a lot of effort to get A in maths and chemistry! (D) F: Don' t be sad! At least you can get an A in history. Everything will be alright!

Ex Output:
D
