answer: #Person1# and #Person2# feel too hot to study in their dorms. #Person2#'s thinking about moving out to an apartment. But #Person1# says electricity is very expensive in an apartment, so #Person2# will see about the other dorm.
documents: #Person1#: I can't stand this heat. I can't get my attention to studying for the midterm exam. I guess I'll have to go to the library this afternoon.
  #Person2#: I don't blame you. This dormitory doesn't have air conditioning. I can't study, either. My roommate and I are thinking about moving out to the other dorm, or an apartment that has air conditioning.
  #Person1#: Oh, I thought about moving too. But if I want to live in an apartment, I have to pay a lot of money for electricity. Do you know an air conditioner is cheaper today than it was 10 years ago? On the other hand, electricity is a lot more expensive today.
  #Person2#: I didn't know that. How much do we have to pay for the electricity?
  #Person1#: 5 years ago, it was possible to run an air conditioner 24 hours a day for mere $20 a month. Today, the same air conditioner in the same house cost more than $40 a month.
  #Person2#: Oh no, that's really expensive. Well, I guess I'll tell my roommate will see about the other dorm. If it doesn't workout, we will sweat all summer.
