input: Please answer the following: Terry: Yes. Frank: It must be an exciting trip. Terry: Well, I've really seen lots of things. I saw the most spectacular view when I was crossing a bridge to Manhattan at dusk, and the skyscrapers were lit up producing a classic nighttime view of Manhattan. Frank: That's really beautiful. Terry: But that's not the whole picture. Some of the streets in New York are very rough. I saw large piles of garbage cans at the roadside, and graffiti all over garage doors and store shutters. Frank: I can't believe it. Terry: The garbage are tidily bagged and boxed, though. Frank: Did you stay in a hotel? Terry: Yes. The hotel we stayed at turned out to be fairly decent, though the room was small, with a tiny bathroom that was only about 3 feet larger than the bed. As I was inexperienced with tourist-area hotels, I was startled, I mean, the room was $129 a night. But at least the room was clean and the bed reasonably comfortable. Frank: What's your general impression of New York? Terry: Well, restaurants pack their tiny tables very tightly; grocery stores and bookstores have aisles that are narrow; the sidewalks are cluttered with newsstands, vendors and their carts, and places that aren't restrictively small, such as the lawns around the Natural History Museum, are full of people, so they're no escape.

output: Frank: Hi, Terry, you're just back from New York.
Please answer this: W: But you should always have something. According to nutrition experts, it's the most important meal of the day. M: That's a load of rubbish, if you ask me. It's all very well for them. They've probably got time for it. I haven't. Anyway, when I get to work, I'm plunged into the usual stressful day, and my hunger just sort of evaporates. W: Yes. I only live around the corner, but I often skip breakfast myself, but I suppose you could always make up for it at the lunch time. M: I should, but more often than not I just grab a cup of coffee and a few biscuits, or a sandwich. W: There's nothing wrong with that. That's all I ever have when I'm busy. M: Fine, but what happens as the day wears on is that the less you eat, the less you want to eat. Abstinence seems to suppress the appetite, somehow. W: Well, I suspect what we ought to be doing is establishing a regular pattern of eating, instead of just grabbing what we can when we can. M: Em, a sensible conventional diet. There's no doubt that's the way to go, so shall we now go and do something for a change? You name the restaurant and I'll treat you to lunch. W: That will be nice.

Answer: M: It's a vicious circle, really. It takes me the best part of an hour to get here in the morning, so I honestly never have time for breakfast.
Problem: W: Are you hungry? M: Well, I am a bit. Aren't you? W: Not very. But I don't mind going somewhere for a light meal. M: Where shall we go? What about McDonald's? W: I'm fed up with French fries and hamburgers. I think we'd better go to the restaurant around the corner. It's a family-type. It serves good food at very reasonable prices. M: OK, let's go. What was said before this conversation?

A: M: Lin Yang. It's twelve already. What about having some thing to eat?
Problem: Given the question: M: Yes, but all I got was a sore foot. What was said before this conversation?
