answer: #Person1# needs to buy a bed that isn't too big. #Person2# recommends a twin bed, and #Person1#'ll get the smallest one.
documents: #Person1#: Excuse me, sir, can you help me? I need to buy a bed for my new apartment.
  #Person2#: Of course, what size bed do you need?
  #Person1#: It's a small apartment so I don't want anything too big.
  #Person2#: Well, you should get a twin bed. That's the smallest size for an adult. It only fits one person. A bigger size bed is a double bed for 2 people. Then there are queen size and king size beds. Those are very large. There are much too big for you.
  #Person1#: OK. Thanks so much I'll get the smallest one.
