Teacher: 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".
Teacher: Now, understand the problem? If you are still confused, see the following example:
W: The movie next Tuesday has been cancelled due to lack of interest. M: What do you mean? W: Well, by last night only a few tickets has been sold.
Solution: What can we conclude about the movie? (A) They want to buy the tickets for the movie. (B) The tickets for the movie were sold. (C) The movie will not be shown.
Reason: This is a good example. Based on the conversation, the movie has been canceled, and it will not be shown. We could understand that only option (C) is correct. As mentioned in the conversation, only a few tickets have been sold, so option (B) is incorrect. We don't know if they wanted to buy a ticket or not, so option (A) is incorrect as well.

Now, solve this instance: W: Hello. Harling's Shopping Centre. Can I help you? M: Hello. This is Mr. Anderson speaking. I saw your advertisement on TV that you have got some good things on men's suits this week. W: Yes, sir. M: What I'd like to buy is a dark, business type suit. Something in wool, I think. W: We have some excellent pure wool suits. Wool has the best of everything, comfort, quality, value. What size do you want? M: Usually I'm a 40 Regular, but I've gained a little weight lately. W: Oh. You'd better have a 42. What color? M: I'd like something dark gray, or navy blue, or even black. And I prefer a solid color. W: You'll be satisfied, sir. By the way, we have a fine selection of ties to go with the suits. Maybe you would like to come to have a look. M: Oh. And how much is it? W: It's twenty-nine dollars, very cheap. M: OK. I'll come over and have a look at it. Thank you. Good-bye. W: Thank you for calling. Good-bye.
