Example Input: F: I'm really looking forward to going camping this summer, Jason. When I get into the forest, I feel like I can finally relax. It's better than any beach. ,M: Me too, Sarah. I can't wait to sit by a fire and sleep in the forest under the stars. The one thing I find stressful, however, is the packing. ,F: Why is that? ,M: We have to bring sleeping bags, clothes, food, water, games and so much more, but we don't have enough room in our car for extra stuff. It's really frustrating. ,F: That's why I want a car with far more enough space like Marie Antonis. They store all their camping things inside. ,M: Yeah, sounds like we have to save up money for a new car.
(A) F: Marie wants a new car like ours, which can store almost everything. (B) F: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (C) F: Tony, we already have a big car. You don't need to buy a new one. (D) F: You agree, right? I've been looking for an appropriate new car.
Example Output: D

Example Input: F: I think I want to go back to school, Paul. ,M: Well, that's a nice idea, Cindy. But what would you study? ,F: I'm not sure. I've always been interested in psychology. I think I'd do really well.
(A) M: I am sorry. You spoke so rapidly that I did not catch the meaning of what you said. Could you repeat that? (B) M: I also think it would help you writing. Go ahead! I support you my bro! (C) M: Are you sure, my daughter? Can you really get good grades? (D) M: Oh honey! Sure you can get good grades, I trust you so much!
Example Output: D

Example Input: F: Why did you decide to publicize climate change in this way? ,M: Well, I was really upset about some countries failure to sign up pollution control agreements. It felt like the science wasn't getting understood by the politicians, so I decided to look into what I personally could do, that led me to dream up a cartoon character called Mr Carbon. We all know somebody like him, he's climate ignorant and makes no effort to save energy. Of course, factories are the obvious bad character in the real world, but I couldn't do much about them.
(A) F: OK, I see. So you create Mr. Carbon because your dream is to make a movie and Mr Carbon makes many effort to save energy. (B) F: So, you create Mr. Carbon because of your disappointment at some governments' inactivity. (C) F: Excuse me, could you repeat the question? (D) F: Well, we all know nobody like Mr. Carbon. You create him because of your disappointment at some governments' inactivity.
