Problem: M: Some of these books aren't so old, though... See? This mystery was published only six years ago. It cost seventy-five cents. You can't beat that. W: Hey! Look at this! M: What? Are you getting interested in nineteenth century poetry all of a sudden? W: No. Look at the inscription! Someone gave this book as a present, and wrote a note on the inside of the front cover. It's dated 1893. Maybe it's worth something. M: Everything on that shelf is worth fifty cents. W: But if this is a signature of someone who is well known, it might bring a lot more. I hear William Shakespeare's signature is worth about a million dollars. What was said before this conversation?

A: W: I enjoy going through a secondhand bookstore, don't you? It's interesting to see what people used to enjoy reading. Did you see this old book of children's stories?

Follow me, please...What do you think of this pair? M: They look nice. How much are they? W: They are 40 dollars, but I can give you a 10 percent discount. M: Good.

The answer is:
W: Good morning, sir. May I help you?
input question: W: Thank you, Brian. It's great to be here. M: OK, so tell us about this new toy. W: Well, it's similar to a relaxation ball in its function, but it's useful for anyone who has problems focusing. M: So, how does it work? W: It's about the size of a cookie, and it has three small round parts that can move in any direction. Basically, you just hold it in between your thumb and middle finger and spin it. That's it. M: That's it? W: Yeah. It's very popular not only with children, but with adults as well. M: A professor at MIT by the name of Jill Meanley has publicly stated there is no scientific or medical evidence for your claims about its benefits. Many schools also have banned the toy, saying it leads to a lack of focus in the classroom. W: Well, that professor is allowed to have her opinion. M: Fair enough. And who invented it? W: Catherine Hettinger, a chemical engineer, was first believed to be its creator, but then we found that an IT professional named Scott McCoskery was the actual inventor. M: It's time for a commercial break. More with Margaret Seabrook in a moment. What was said before this conversation????

W: Yes. I've heard of it actually. I suppose you must like it. M: Yes, I mean it's marvelous. W: Oh, Jeff. I really can't agree. I don't like it at all. My shop is much better. M: You must be mad. I think it's really...you know...so easy to buy everything in one place. W: Yes, it's easy. But don't you think the food isn't...I mean small shops usually have much fresher food. M: Maybe, but you pay for it. Small shops are more expensive, aren't they? W: Yes, I agree with you, but supermarket staff are badly paid and they are really...but you get better service in small shops. They are much more friendly. M: No, everyone in my supermarket is very nice. What was said before this conversation?
