[A]: M: Excuse me, I have a ticket for the 6 o'clock flight to New York. But I'm afraid I can't make it. Is there a seat available for tomorrow morning?

[Q]: M: I'm usually up by 6:00 and out of the house by 6:15. W: That's pretty early. Don't you start work at 9:00? M: Well, I go to the gym every morning before I arrive at the office. There aren't many other people there at that time, and I usually don't feel like exercising after a long day at work. But the real reason is that it gives me the energy I need to make it through the day. W: So, you take a shower at the gym every morning? M: During the week, yes. I don't go to the gym on the weekend. I get all the exercise I need playing with my two sons at the park! W: I'll bet! My husband is always tired after he takes our daughter hiking in the mountains on the weekends. M: Hey, Sophie, we should all get together and do something fun this weekend. I know Molly would love to see you. W: That sounds great. What was said before this conversation?

[A]: W: What time do you get up to go to work, Jerry?

[Q]: M: Thank you. It's a photo that I took on my vacation last year. W: You took it yourself? M: I've been taking pictures for years. W: Sounds interesting. Can I see some more of your pictures? M: Yes, certainly. Some of them are just faces of people who interest me. W: Do you let them know that you're taking pictures of them? M: I try not to. I like people who are going about their business without knowing the camera is there. W: I suppose you need a lot of equipment. M: Well, I have a dozen cameras, but I use two of them more than the others. What was said before this conversation?
