A、John cheated in the test. B、George passed the economics test. C、The woman failed in the economics test. D、Professor Smith knew

W: Oh, George, I feel terrible. I told Professor Smith that John cheated in the economics test.
M: You did what?
W: I had to, George. I had no choice. Yesterday Professor Smith asked me to go to his office. He said that I failed in this mid-term test quite badly. Even John, who seemed to do no work at all in class, managed to do so much better than I.
M: And then?
W: He asked me if there was anything that I wanted to talk about. And he pointed out that me and John just didn’t seem as close as we I used to be. There must be something wrong.
M: So you told him about John?
W: Yes. But at first I didn’t say it was John who cheated. I said that I had this friend, and she had a problem. She thought a friend of her was doing something wrong and now she didn’t know what to do. If she reported him, he’d know it was he and probably wouldn’t ever speak to her again. But, if she didn’t report him, he’d just get away with it.
M: Then what did Professor Smith say?
W: Well, she said me what I thought my friend should do. I said I didn’t get a clue. He then said I could tell my friend that he was extremely suspicious about someone’s unusually high test score recently, and he also overheard some very worrying comments about photocopying being very easy.
M: It seemed that he already knew who cheated in the test.
W: Yes, so I told him it was John.
M: I think you are right.
W: Really? Do you really think so?
M: Yes, if I were you, I would do the same.
