Problem: Given the question: W: Don't ask me. M: What do you mean? Did something go wrong? W: Susan thought I had said I would meet her at the Department Store at 2:30 when I really said 2 o'clock. Then she thought I had said the main entrance in the front when I really said the east entrance. M: Well, did you ever get together? W: Yes, but it's a wonder that we did. I had given up waiting and had gone inside to the women's clothing department. She had done the same thing. We met by accident. By that time it was 3 o'clock. M: Did you get what you wanted? I remember you said you wanted to get a sweater. W: No, a blouse. But by that time, the ones on sales were all gone. So I settled for a skirt. What was said before this conversation?

The answer is:
M: Well, Betty, how was your shopping trip with Susan this afternoon?
input question: W: Well, like so many easy questions, the answer isn't very simple. Basically, human memory is a compartment in people's brains where they store images rather like the hard disc drive in a computer. And like a hard disc drive, our memories can become infected or even wiped out by accidents. But the comparison breaks down when we consider that we can train our memories to expand and work better which computers can't manage yet. M: When you talk about memory being infected, do you mean by a disease? W: Yes. For instance, people suffering from a physiological disease like Alzheimer: forget things that happened in the past. And they also forget how to perform simple tasks like tying their shoelaces. The good news is that brain exercises can help keep the brain young. Research has shown that people who have better educations and more mentally active jobs have a lower risk of developing the disease. M: And how can someone exercise his brain? By thinking a lot? W: In a way, yes. But you can also practice using your memory which not only exercises your brain but also improves you ability to remember things. Unfortunately, a lot of devices in modern life are designed to make sure we don't forget things which can make our brains more idle and weaken our memories. M: Can you give us some examples of how to exercise our memories? W: Sure, there is a very simple technique, although it works better for some people than for others. When you want to remember something, think of a physical thing it reminds you of. If I want to remember a date from history, let's say, 1066, the date of the Battle of Hastings. I might think that battle reminds me of bottle, so I think of a bottle with the number 1066 written on the label. And I just picture that bottle to myself. What was said before this conversation????
output answer: M: Today on mind matters, I'm talking to Dr Ann Winters, an expert on human memory.. Ann, welcome to the program. Now, I suppose the first question everyone would ask is: what exactly is human memory?
W: It was built in 1944. M: Is it the same as the computers that we use now? W: No, it was as large as a room and worked very slow. M: But computers have become smaller, and worked faster now. W: Yes. Most computers are as small as a TV set. Some can be made smaller than a book. M: Why is a computer so useful? W: It can keep much information and work very fast. M: Then they can do a lot of work for us. W: You are right. They have greatly changed our lives. What was said before this conversation?
