In this task, you will be shown a conversation. You need to write a question with three choices for the conversation. Your question should be answerable based on the conversation and only have one correct answer. Note that you don't need to answer your question. "W" and "M" in the conversations stand for "woman" and "man".

[Q]: M: How much are these T-shirts? Are they also on sale? W: Yes, they are usually $30 a piece, but they are on sale and you can get 30 percent off.
[A]: How much does a T-shirt cost now? (A) $21. (B) $27. (C) $30.

[Q]: M: I paid fifteen dollars for three books. I think they are too expensive. W: Expensive? You shouldn't have said so.
[A]: How did the woman feel about the books? (A) She liked them very much. (B) She didn't like them at all. (C) She thought they were cheap.

[Q]: M: Hi, Mary. We haven't seen each other since we graduated. Where have you been? W: I have been to Australia. Do you still live there? M: Oh, no. We have just moved into the new house. W: Really? Congratulations. M: Thank you, and we want to buy a new television. W: What kind of television do you want to buy? M: A color TV, of course, but I'm not sure about the size. Maybe we should buy a bigger one. If we buy a smaller one, we might have to change it in a few years' time for a bigger one. That would be a waste of money. What is your opinion? W: In my opinion, I don't think it's necessary to buy a very big one. M: Any reason? W: Yes. As I know, your sitting room isn't big enough. If you put in a very big television, that will be bad for your eyes, and a smaller size TV can also pick up good programs. M: Mmm, that's quite true. I'll think about it. W: You'd better make a quick decision because the price may go up soon.
[A]:
What kind of color TV did the man plan to buy? (A) A cheaper one. (B) A bigger one. (C) A smaller one.
