documents: #Person1#: Excuse me, Professor. I think there might be an error in my test score.
  #Person2#: Sure. Do you think that the total is wrong or that you got something marked wrong that should have been marked right?
  #Person1#: I think that the percentage is incorrect.
  #Person2#: Let's just go over all of it to double-check.
  #Person1#: Sure, let's do it.
  #Person2#: Here is the answer sheet. Do you see a place where I marked something wrong that should have been right?
  #Person1#: I don't see any mistakes.
  #Person2#: OK, now that we've gotten those straightened out, let's total the score.
  #Person1#: Yes, let's total it.
  #Person2#: Well, if I total that like this and divide by this number, I get this total. Do you agree?
  #Person1#: Yes, you're right.
  #Person2#: Well then, we are all straight. Have a good day and thanks for bringing that to my attention.
