Input: Consider Input: F: How dangerous it was and how lucky the girl was. ,M: Yes, but for the passerbys quick action the girl would have been run over by the car.
(A) F: Yes, there was traffic accident. How bad luck the girl has. (B) F: I am really sorry, I did not catch that. Would you slow down, please? (C) F: The girl is badly ill. (D) F: I hate that thief.

Output: B


Input: Consider Input: M: I'm really surprised you got an A on the test. You didn't seem to have done much reading. ,F: Now you know why I never missed the lectures.
(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: Wow! You have reviewed all the notes? No wonder why you got an A on the test. (C) M: So you mean that you have attended every lecture and it helped you get an A on the test? (D) M: So you mean that you have attended every lecture but it didn't help you to improve your grades?

Output: C


Input: Consider Input: M: Do you usually feel nervous, anxious or scared during tests, Jane? ,F: I used to. ,M: How did you get over it then? ,F: Believe it or not, tests don't mean that we should do extra work. Teachers and schools give us tests for very important reasons. Knowing it is very important for you. ,M: I see, but sometimes it can't help. ,F: Giving a test is a way for a teacher to see what the students have learned, and to find out who is having trouble. Then he can decide on the teaching plan.
(A) M: That makes sense, schools really need to know that their students have learnt and help teachers be well prepared for the class. (B) M: Yeah, schools need to check the level of those teachers by giving students tests, I guess that's why you never feel nervous during tests, right? (C) M: I am afraid I did not quite catch what you were saying. Please repeat it. (D) M: Right, schools usually provide their students extra work by giving them tests so as I said, tests mean you should do extra work.


Output: A
