output answer: W: Welcome to Youth Hotel, can I help you?
W: That's all right. John. My house is not that easy to find. But you know you wouldn't have gotten lost if you had a smart car. M: A smart car? What's that? W: I just read a magazine article about some new technology that can make a car smart. One device is a computerized map display and an artificial voice. You just enter the address for where you want to go and the voice will tell you how to get there,street by street. M: Hey, that's just like my brother. He never gets lost and he's always telling me the best route. So what else will the smart cars be able to do? W: Well, the article says there'll be a device with read-on warning systems that will warn drivers with a long signal if they're getting too close to other cars. And they will even put on brakes if the drivers don't. M: Tell me, Shelly. Will these cars be smart enough to fill themselves up with gas? W: Not by now. Why do you ask? M: I'm not late because I got lost. I'm late because I ran out of gas on the way over there. What was said before this conversation?

Q: M: Oh! Hi, Laura. What are you doing here? W: Uh, I'm usually here on weekends. It's my uncle's shop. So you are looking for a bike? M: Yeah. Now that the weather is warming up, I thought I should get some exercise instead of taking the bus all the time. W: Well, that's a good idea and you come to the right place. Do you know what you like? M: Well, I don't want a racer or a touring bike or anything like that. Mostly I'll just be using it to get me back and forth from work. W: How far is that? M: About four miles. W: Are there a lot of hills on the way? M: Some, I guess. But maybe I should tell you at first that I only got 150 dollars. Can I get anything decent for that? W: Well, you are not going to get anything on the top of the line. But we do have a few trade-ins in the back that are in good condition. M: That sounds good. W: And you are right. For the kind of ride you are going to be doing, the most important thing is comfort. You want to make sure it's the right height for you? Follow me and I'll show you what we've got.
