Example Output: B

Example Input: F: I have been having a lot of trouble managing my time. I always forget my test and homework, due dates and I can never find the right notes I need. I heard that you're really organized. Do you think you could help me? ,M: Sure, I'd be happy to help. First of all, you need to get a planner, like this one. It's a small notebook in calendar where you can write down all the important dates you need to remember. Then you should create some sort of filing system to organize your notes. I use different colored files to keep the papers for my different classes.
(A) F: I'm sorry, I didn't catch that. Would you mind speaking more slowly? (B) F: Really? You mean you'd not be happy to help me? Oh, we are classmates. (C) F: So, you mean first I don't need to get a planner? Okay, I will take your advice, teacher. (D) F: Oh, you are the considerate classmate. I will take your advice. Thank you.
Example Output: D

Example Input: M: We still have one more day to go before we return home. What do you want to see tomorrow? ,F: No idea. We've enjoyed both the natural scenery and the city sights? What else is there to see? ,M: How about a factory tour? ,F: You mean visit a factory? ,M: Yes, I heard there's a large car company nearby that is open to the public every weekend. We can go there to see how a car is made and learn more about the car industry. ,F: Good idea. I've always been interested in that. How much is the entrance fee? ,M: I'm not sure, but as far as I know, most factory tours are free. They are sponsored by the car company providing the tour.
(A) F: Wow, we can't miss the opportunity since it is sponsored by the car company. (B) F: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (C) F: Now that it is sponsored by the car company, let's visit it next Monday. (D) F: I don't want to visit it because it is only good for the company and we can learn nothing about the car industry.
