Question: W: I've started running to work instead of taking the bus. It's good for the environment. M: I drive to work. I keep fit at the gym. W: Well, running gives me a wonderful feeling of freedom-it's just what I need before sitting down in the office every day. M: Are you going to join in the big race next month? W: I'd like to. Are you going to take part in it? M: Oh, yes. But I'm not going to train by running to work. I'll run around the park a few times when I get home in the evenings. W: OK. Anyway I must go now or I'll be late. Bye. What was said before this conversation?
Answer: M: Hi, Natasha. I see you're going out for a run. You don't have to go to work 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?

Please answer this: Customer: Yes. I'd like a large pepperoni pizza with mushrooms and green peppers. Employee: Would you like anything else? Customer: Well, wait. Uh, can I make that a half-and-half pizza? Employee: Sure. What would you like on each half? Customer: Uh, what toppings do you have? Employee: Well, we have Italian sausage, ham, mushrooms, onions, pineapple, black olives, green peppers, bacon, tomatoes, shrimp, clams, and squid. Customer: Shrimp, clams, and squid!? What kind of pizza is that? Employee: Uh, the manager spent some time overseas [Oh.], and thinks his new seafood pizza will be a hit with customers, but to be honest, the "Swimmer's Special," as he calls it, is an acquired taste. Customer: Uh, I'll pass on the "Sink or Swim" special, but I'll have pepperoni and mushrooms on one half and green peppers and Italian sausage on the other. Oh, and could I get extra cheese on that pizza? Employee: Alright. Would you care for any bread sticks or beverage with your order? [Well ...
