My grandpa has something wrong with his ears. He doesn't hear well. ,F: I'm sorry. I misunderstood you. Your grandpa looks kind. ,M: Yes, he is kind to everybody in our small town. So we all respect him. ,F: He looks quite old now. He must be in his seventies, right? ,M: Yes, he is 75 years old this year. ,F: Though he looks so old, he is still in good health. ,M: Yes, of course, he gets up early every morning and does some exercise in our garden. That's why he is still in good health. ,F: How's your granny? Is she still in good health like your grandfather? ,M: She was 5 years younger than my grandfather, but she died of heart disease 3 years ago.
(A) F: Sorry to know your grandmother passed away this year at the age of 75. (B) F: Excuse me, could you repeat the question? (C) F: Oh, I'm sorry to hear that your grandmother died in a quite young age of 67. (D) F: I feel sorry. As she left at the age of 65 last year, you must miss her a lot.

Example Input: M: We've just moved into a new house. ,F: Really? Congratulations. ,M: Thank you. I think we want to buy a new television set. ,F: What kind of television do you want to buy? ,M: A color TV set, of course. But I'm not sure about the size. Maybe we should buy a big one. If we buy a small one, we might have to exchange it in a few years for a bigger one. That would be a waste of money. What's your opinion? ,F: In my opinion, I don't think it's necessary to buy a very big one.
(A) M: Why do you think we should get a small TV set but now a big one? (B) M: Yeah. We should buy a small TV set and change it in the future. (C) M: I agree with you. We should buy a big TV set instead of a small one. (D) M: Excuse me, could you repeat the question?
