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: Did you take these pictures? They are very good. W: Yes, I think they turned out very well too. I like to bring my camera with me wherever I go. That way if I see something attractive I can snap a picture of it. M: Carrying a big camera around is too much trouble for me. W: My camera is really small enough. Here let me show you. M: That is a compact camera. But you must know a lot about photography to get such professional looking results. W: Not necessarily. This camera is simple to work. M: Does this model come with a flash attachment for indoor shots? W: Better than that. It has a built-in electronic flash and an automatic focus too. I don't even have to worry about focusing. M: That's what I need. When I take pictures, they usually come out blurry because I don't adjust the lenses properly. And I hate photos that are out of focus. Is a camera like yours very expensive? W: Less than you'd expect. Why don't you check the prices that Headfields demonstrates? This model was on sale there last week. M: I think I will. It certainly won't hurt to take a look.
A:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
