output: M: Hello, Mrs. Tailor, is Peter there?
Please answer this: W: Don't feel discouraged. Be patient. As you are so distinguished, you will definitely find the person who is right for you. M: To tell you the truth, I am tired of being alone. I hope to find my Mrs. Right. What should I do? W: Do you believe in Internet matchmaking service? M: That's really a new walk of life. What is it exactly? W: It helps match up singles the world over, and helps find the man and woman of their dreams. M: Oh, it must be to the taste of a certain group of people. W: The advertisement said Dream Dates has matched up thousands of singles the world over! M: Unbelievable! They must be exaggerating the figure! W: Look at the way they manage their business: they collect applicants' photos, and give the applicants questionnaires to fill out as to what type of character they are. M: I don't believe several questions can decide the type of person you're. People's characters are complicated and keep changing all the time. W: Anyway, it seems that things work well this way. The information and specifications will be entered in a large computer database. M: A computer to decide your best date? That's really ridiculous! W: Look, it promises: Dream Dates provides expert dating service and a place for singles to meet. We'll introduce you to the person uniquely qualified to be your partner. M: Sheer slogans! Not reliable! W: It says you can enroll in a free trial membership! M: I won't do it even they pay me for that! W: Well, we don't have to believe this. Maybe I can tell John, and see whether he'd like to try it. What was said before this conversation?

Answer: M: I don't enjoy dating anymore. I can't seem to find anyone I have anything in common with.
Problem: 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?
