input question: M: OK, here's my story, I was about 18 months old I think and I had just started to say my first word. Every time a truck went by, I would shout a word that sounded like a track, but to everyone else, it sounded nothing like it. My parents tried to correct me, but failed. Then, about three months later, we traveled to New York, as we were waiting for our plane at the air?port. I looked out of a huge window, at that very moment I saw the largest truck in the world, I had to tell someone about this. I turned to my father who was standing next to about a thousand people waiting for the very flight and screamed "Track! Track!" My father tried hard to shut me up, but I was so excited, I kept screaming my special word. My poor mother decided she didn't know this baby and then ran into the ladies-room where she hid until I finally stopped. Well, I learned how to say truck correctly, and soon I was talking like a normal child. However, my parents will never forget the very first word I produced in my life.

Q: W: I'm waiting for a bus. The buses are so full at this time of the day. M: Sure. Where are you going? I don't think this is your way home. W: You are right. I'm going for a walk in the park. M: Going for a walk even after along day's work? W: Yes. I always enjoy walking alone in the park after work. M: I see. Then why not go there on foot? It's not so far from here. W: Oh, no. I hate walking through the streets. What was said before this conversation?
A: M: Hello, Mary. Why are you standing here?
Question: W: Hi, Mark! I've just got back from the Art Gallery. They had a wonderful art exhibition today. You shouldn't have stayed home and worked on that paper. I think you would have been inspired by some of the paintings. M: Oh, Idon't know. I don't really care for modern art. W: I think you should think ofmodern art like food. You need to taste things to see if you like them. You know, some of the pieces at the exhibition were even for sale. The last one was on sale for $9,000. M: $9,000? Well, I may go and visit the exhibition tomorrow, but I'm not going tobuy anything. W: OK, let me know how it goes, won't you? And you might give Tom a call. He wanted to go with me today but his aunt was intown so he couldn't. He really wants to go. M: OK, I will. What was said before this conversation?
Answer: M: Hi, Jenny. What did you do today?
[Q]: M: Yes. It explains how science will revolutionize the 21st century. W: Could I ask you some questions concerning the book? M: Sure. W: Are you optimistic about the future? M: Generally, yeah. If we go back to the year of 1900, most Americans didn't live beyond the age of 50. Since then, we've had improvements in health care and technology. There is no reason why these won't continue far into the 21st century. W: Are we ready for the changes that will come? M: Changes are already happening. The future is here now. We have DNA, microchips, the internet. Some people's reaction is to say, we are too old; we don't understand new technology. My reaction is to say, we must educate people to use new technology now. W: Is world population going to be a big problem? M: Yes, and no. I think that world population will stop increasing as we all get richer. If you are a part of the middle class, you don't want or need 12 children. W: Will there be a world government? M: Very probably. We will have to manage the world and its resources on a global level because countries alone are too small. W: Will we have control of everything? M: I think we'll learn to control the weather, volcanoes and earthquakes. Illness won't exist. We'll grow new livers, kidneys, hearts, and lungs like spare parts for a car. People will live to about 130 or 150. For 2000 years, we have tried to understand our environment. Now we'll begin to control it. What was said before this conversation?
