I heard that Jason is likely to be at the top of his class after his exams this year. ,M: Yes, so his teachers say he's been buried in his books every evening for months on end recently. He is hoping to go to Harvard University. ,F: Great. Maybe he'll become a university professor himself in the future. ,M: Maybe, but sometimes I wish he'd go out and enjoy himself for a change. ,F: How about the younger one? ,M: Well, Mark's teachers say he has ability, but he rarely does his best. He does his homework in 10 minutes every day and then rushes out to play football. ,F: But he can make his fortune at football. People can make a lot of money from sports now. ,M: My wife always worries about their future. She wants Mark to study law. I don't believe in forcing them. But I wonder how Mark will progress over the next few years. ,F: Perhaps you, you can have a talk with him now to find out what he's thinking about his studies and future plans.
(A) M: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (B) M: That is right. I should talk with Mark with his future plan. I feel worried about him. (C) M: Good idea. I should talk to my wife about my two daughters. They are too naughty. (D) M: Thanks for your advice. I will have a talk with Mark about his plan for Harvard University.

Example Input: F: Did you get the injury playing football, Jim? ,M: Yes, one of the boys kicked my foot instead of the ball. ,F: The best thing for you to do is to rest your leg for 48 hours. ,M: When can I go back to school? ,F: You can go back in 4 days. But you'll need to avoid sports for a month.
(A) M: OK, I didn't expect I can go back to school in four days. (B) M: I am really sorry, I did not catch that. Would you slow down, please?

Why does it take a month to go back to school?
