answer: #Person2# is tired after class. #Person2# tells #Person1# one of #Person2#'s friends failed the Adult College Entrance Exam because of a silly mistake. #Person1# thinks they must familiarize themselves with the exam from now on.
documents: #Person1#: Finally the class is over. Be quick. Ben must have been waiting for long.
  #Person2#: Oh, I am so tired. My back is sore and my neck hurts.
  #Person1#: That's normal. You have been sitting for three hours, with your attention highly concentrated.
  #Person2#: You are wrong, Shirley. I was always absent-minded in the class. I meant to concentrate on the class, but I was just so tired. Maybe I am old.
  #Person1#: No. You are just burning yourself out these days. Have a good rest and you will feel energetic again.
  #Person2#: One of my friends took the Adult College Entrance Exam last year. He filled the school column with his name, and his score was relinquished.
  #Person1#: How could he make such a silly mistake?
  #Person2#: He said he hadn't taken any exams for ten years, and couldn't get used to it immediately. He was extremely nervous then.
  #Person1#: He lost a very good chance to go to college, didn't he?
  #Person2#: Yeah. The test was fairly easy and almost every test-taker could pass that exam. Adult College Entrance Exam is much easier than college entrance exam. And there are fewer subjects.
  #Person1#: That's a very good lesson. We must familiarize ourselves with the exam from now on.
