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: M: What's that book you just picked up? W: The sociology text professor Smith uses in his course. M: You had better read it if you want to pass the course. W: But it is too expensive. I simply can't afford it. M: How much does it cost? W: It costs 40 dollars. M: Did you check the used book section here? Maybe they have one. W: No, they don't. I have asked. M: Why don't you get it from the library? W: Are you joking? I've been trying for months and the book is always out. There are more than 45 students in the course and every single one wants the book. M: Listen, you know my roommate, Henry, don't you? He took the same course last year and I believe he owns the book. I'll ask him if he'll lend it to you. W: Oh, Tom, that would settle everything. That's very kind of you. M: My pleasure.
Student:
Why doesn't the woman buy the book? (A) Because it's too expensive. (B) Because she doesn't need it. (C) Because she can buy it everywhere.
