answer: #Person2# wants to buy a walkman. #Person1# recommends one with auto-reverse but #Person2# doesn't want it because #Person2# has broken two walkmans with auto-reverse. #Person1# tells #Person2# that might be caused by dust but #Person2# still doesn't trust auto-reverse and buys one without it.
documents: #Person1#: Can I help you?
  #Person2#: Yes, I would like to buy a Walkman. Can you tell me about the models you have?
  #Person1#: Well, we have a lot of models here. Did you want to listen to CD's or cassettes or the radio?
  #Person2#: Mostly cassette tapes.
  #Person1#: Alright. There are several models you may want to look at. This Kreng portable cassette player is very good.
  #Person2#: Kreng? I've never heard of that company.
  #Person1#: It's a German company. This unit has auto-reverse, recording capability, and an AM / FM radio band. It also has a built-in microphone.
  #Person2#: I suppose I don't want that one then. I don't like auto-reverse. It breaks too easily.
  #Person1#: Really? Have you had an auto-reverse break before?
  #Person2#: Yes, twice now. I think it's too high-tech, and so it's the first part that breaks.
  #Person1#: Hmm. You know, the problem might be dust. Did you clean the unit often?
  #Person2#: Well. No, I didn't clean it. But still, I only had the last one two months, and it broke. I don't trust auto-reverse.
  #Person1#: Alright. Well. We have many units without auto-reverse. Here is a good unit. Very reliable. It has an AM / FM band, built-in microphone, recording capability, and no auto-reverse.
  #Person2#: How much is it?
  #Person1#: This one sells for $ 39. 99.
  #Person2#: Can I test it out?
  #Person1#: Of course.
  #Person2#: It sounds great. I'll take it.
  #Person1#: Fine. I think you'll be happy with it. It's a very good unit. Very reliable. I'll go get you a new one in a box. I will be back in just a moment.
  #Person2#: Thanks.
