[Q]: M: Yes, I have lived here since I was born. I have lived here for thirty years. What was said before this conversation?
****
[A]: F: Have you lived here before you went to work?
input: Please answer the following: 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?

output: W: Hi, Professor Smith. I hear you've written a book titled Visions.
Please answer this: W: I hope you didn't leave it in school. You never know where you put your things. When did you last see it? M: Last night before I went to bed, I think. I remember putting it on the desk. W: Really? If you put it there, it should still be there. No one has been to your room. So it must be here somewhere. M: Yes, but where? That's what I want to know. Oh, dear, it's about the time for the school bus. W: Hey, what's that under your blanket at the foot of your bed? What was said before this conversation?

The answer is:
W: Something is wrong with our TV.
Problem: M: Well, I don't think it's so bad. But I do think that going to the dentist is stressful. W: Oh, so do I! It's stressful because you have no control. M: That's right. Look at this one. This poor boy is sitting in an exam. I think exams are the most stressful. Sometimes you just can't think of anything to write. W: Yes, I agree with you there. What about these people here? M: Mmm... I'm not sure. They seem to be in a hurry, don't they? I think being late is stressful. W: That's true. It can be terrible, especially when you're late for something important. M: Like an interview. Look at this picture here: here's someone in an interview. Do you think interviews are stressful? W: No. I think they're quite exciting, a challenge. M: Oh, I hate interviews.
