Example Input: M: Hi Judy. Did you see this notice in the dining hall? ,F: Yeah, Sam. I don't like it. I usually sit here and talk with my friends after lunch until my first class at 2:00 in the afternoon. Now we have to find someplace else to go. ,M: But we have lots of other places to go. We can go to the school park. ,F: That means carrying all my books. ,M: But they explain this will help keep the cost of food down and we can save some extra money.
(A) F: OK, since it can help me to save money, I'd like to take a try. I hope the dining hall would open as soon as possible. (B) F: Well, but I don't think we can go to more places. Our class in the afternoon will begin at 1:00, we don't have time. (C) F: So let's go to the school park. That can help us save money, and I don't need to carry all my books. That's cool. (D) F: I’m sorry, I don’t understand. Could you say it again?
