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?
