answer: #Person2# wants to buy a VCR for his son as a graduation gift since he wants to be a movie producer. #Person1# suggests #Person2# buy a DVD player which is a little more expensive because it has a better quality of the image and can keep tapes forever, while videotape breaks down after fifteen years. #Person1# will show #Person2# some of their DVD players.
documents: #Person1#: May I help you, sir? 
  #Person2#: Yes, I want to buy a VCR. 
  #Person1#: Well, we have many models to choose from here. Do you have a particular brand you want? 
  #Person2#: No. I only want it to be a very good one. The best. It's a graduation gift for my son. 
  #Person1#: I see. And does your son have a VCR now? 
  #Person2#: Well, he uses our VCR at home. But he's going to university in the Fall, so he needs his own VCR. 
  #Person1#: Does he watch a lot of movies? 
  #Person2#: Yes, he sure does. In fact, he wants to become a movie producer himself. He wants to study film at the university. 
  #Person1#: I would like to make a suggestion then, sir. 
  #Person2#: Please do. 
  #Person1#: If your son wants to study film, probably he will start to collect movies himself. 
  #Person2#: Yes, I know that. So I want him to have a good VCR to use. 
  #Person1#: May I suggest you consider buying him a DVD player instead? 
  #Person2#: DVD? Isn't that like a CD? 
  #Person1#: It is very similar. The technology is the same. 
  #Person2#: Why is a DVD better than a VCR? 
  #Person1#: For one thing, sir, the quality of the image is usually better. That's because it's digital. 
  #Person2#: But isn't it more expensive? 
  #Person1#: It is a little more expensive, sir. But there is one important advantage which your son might appreciate. 
  #Person2#: What's that? 
  #Person1#: If your son starts to buy video tapes, he can't keep them very long. 
  #Person2#: And why not? 
  #Person1#: Video tape breaks down after fifteen years. So if he collects a lot of tapes, after fifteen years they will all start to rot. 
  #Person2#: Hmm. Is that true? 
  #Person1#: Yes, it is, sir. 
  #Person2#: Well. And what about DVDs? 
  #Person1#: This is the excellent thing about DVDs. If your son starts to collect DVDs, they will last forever. They will never rot. 
  #Person2#: Hmm. He might really appreciate that. I know he will start to collect movies at school. Especially if he studies film. 
  #Person1#: So let me show you some of our DVD players. In my opinion, DVD is the wave of the future. 
  #Person2#: Alright, please show me what you have.
