user: 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????

input question: M: What we've learned is the fact that he left the Level One Club, which is a drinking club in Neasden Lane, about 1:30 a.m., and we're trying to account for movements up till 2:15 a. m., because it was about that time he was found by a member of the club, an employee. He was found in the underpass, the pedestrian way, under the North Circular Road. Death was due to multiple head injuries. We understand that there may have been two girls and a man who was drunk in close proximity to the entrance to the subway, who may have seen the man walking in that direction, or any attacker who may have been following him.  W: About what time would you think that they were there?  M: Just after half past one to a quarter past two.  W: Then in that case the gap you have is really quite short. It's only more or less half a hour or forty minutes.  M: In fact, yes, as short as that.  W: And how far away from the Neasden underpass was the drinking club?  M: Fifty meters.  W: And at the moment you know of no other people in the area whom you want to talk to, other than the drunken man and the two women who were seen with him or near him at some time?  M: Yes. The club closed at half past one and there may have been other people who left the club who went that way. We understand that there were also minicab drivers parked in the area who may have seen something as well.  W: As it is, I take it you haven't been able to identify them.  M: No, not at this stage.  W: Well, thank you very much.  What was said before this conversation????

input question: M: Well, I should be. I've lived here all my life. What are you looking for?  W: The Post Office.  M: Well, the nearest one is about a mile away.  W: Oh. Well, I guess I could send a letter.  M: There's a mail box up the street. Have you already got a stamp on that letter?  W: Yes, I have to register it. How do I walk to the post office from here?  M: Go up this street until you get to the main street. Then turn right and walk about four blocks or so.  W: Thank you for your help.  M: The post office entrance is inside a building complex with some other offices.  W: I'm sure I'll find it. If I get lost, I'll ask again.  M: There's an American flag out front, and a sign: The U.S. Post Office.  W: Thanks again. Bye.  What was said before this conversation????
