answer: #Person1# tells Mary #Person1# wants to buy a new television but #Person1#'s not sure about the size. Mary suggests buying a small one because the space in the new house is limited.
documents: #Person1#: Hi, Mary. We haven't seen each other since we graduated. Where have you been?
  #Person2#: I have been to Australia. Do you still live there?
  #Person1#: Oh, no. We have just moved into the new house.
  #Person2#: Really? Congratulations.
  #Person1#: Thank you, and we want to buy a new television.
  #Person2#: What kind of television do you want to buy?
  #Person1#: A color TV, of course, but I'm not sure about the size. Maybe we should buy a bigger one. If we buy a smaller one, we might have to change it in a few years' time for a bigger one. That would be a waste of money. What is your opinion?
  #Person2#: In my opinion, I don't think it's necessary to buy a very big one.
  #Person1#: Any reason?
  #Person2#: Yes. As I know, your sitting room isn't big enough. If you put in a very big television, that will be bad for your eyes, and a smaller size TV can also pick up good programs.
  #Person1#: Mmm, that's quite true. I'll think about it.
  #Person2#: You'd better make a quick decision because the price may go up soon.
