Problem: M: Why not? It's Saturday afternoon, isn't it? W: Yes, but there's so much to do around the house. M: It can wait. W: We ought to finish washing down the kitchen walls and cupboards. M: We can do that tomorrow. We don't have to do it today. W: All right. That's a good idea. M: Talking about washing down the kitchen-where's Bob? W: He's having lunch with Georgia. M: What! Again? W: He should be back soon. M: He shouldn't spend so much time with that girl. W: You must be patient, David. Nineteen's a very difficult age, you know? M: Yes, I know. But he ought to be studying more. What was said before this conversation?

A: W: David, we shouldn't sit here doing nothing.
Problem: Given the question: M: Oh, thank you. It's a photograph that I took on my vacation last year. W: You took it yourself? I didn't know you were a photographer. M: Oh, yes, I've been taking pictures for years. W: It sounds interesting. Do you have any more of your pictures here? And may I see them? M: Yes, certainly. Some of them are faces, just faces of people who I see when I'm walking around. W: Do you let them know that you're taking pictures of them? M: I try not to. I don't like pictures of people who purpose for the camera. I like people who are going about their business without knowing the camera is there. W: I suppose you need a lot of equipment. How many cameras do you have? M: Well, I have a dozen of them, but I use two of them more than the others. What was said before this conversation?
