answer: Dr. Jackson gives #Person1# tickets and tells #Person1# the radios and televisions are on the ground floor, and the communication equipment is on the first floor. Jackson's dealt with Cosmic computers but he wasn't satisfied.
documents: #Person1#: That looks like the main entrance. Do we have to buy tickets?
  #Person2#: No, I had several tickets sent to me. Here, take one each. Let's have a look at the equipment. The exhibition is on the two floors, with two main halls on each floor.
  #Person1#: Then what's on the ground floor?
  #Person2#: Radios, televisions, video equipment and home computers-all in Hall 1. Office equipment is in Hall 2.
  #Person1#: How about the first floor?
  #Person2#: Here we are. The communications equipment and large computer systems are upstairs. About every major computer company in the world is here, it seems.
  #Person1#: Dr. Jackson, are there any companies here that you've dealt with before?
  #Person2#: Oh, yes, several. We've had dealings with Cosmic Computers for some years, but we're not satisfied with their after-sales service-they take a long time to deliver spare parts and charge more.
  #Person1#: I've heard some very good reports about another firm called Universal Computers.
