dialogue: W: That looks like the main entrance. Do we have to buy tickets? M: 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. W: Then what's on the ground floor? M: Radios, televisions, video equipment and home computers-all in Hall 1. Office equipment is in Hall 2. W: How about the first floor? M: Here we are. The communications equipment and large computer systems are upstairs. About every major computer company in the world is here, it seems. W: Dr. Jackson, are there any companies here that you've dealt with before? M: 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. W: I've heard some very good reports about another firm called Universal Computers.
question: Why wasn't the man satisfied with Cosmic Computers?
choice: They didn't sell spare parts. They delayed sending computers. Their after-sales service was poor.
answer: Their after-sales service was poor.
