answer: #Person2# wants to buy a stereo system with a turntable and #Person1#'s store has got one available.
documents: #Person1#: Welcome to Super Stereos. What can I do for you?
  #Person2#: I'd like to look at your stereo systems. Do you have anything on sale?
  #Person1#: Yes, this system over here is on sale for $ 1, 000. As you can see, all of the components are brand-name.
  #Person2#: But it doesn't have a turntable. I have a fair number of vinyl records, so I need something to play them on.
  #Person1#: Our selection of stereo systems with turntables is somewhat limited, but we do have this system over here.
