answer: #Person2# wants to buy a VCR as a graduation gift for his son who wants to become a movie producer. Then #Person1# recommends him to buy a DVD player instead because DVDs will last forever.
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.
