You are the principal of a middle school. Two 7th grade girls are brought into your office by their teacher; he accuses the girls of cheating. Each student submitted an identical, typed report and claimed that it was her original work. There appears to be no one who can verify either story. Who, if either of them, is cheating?

• How would you go about determining who cheated and who did not….or if both did not cheat or if both cheated? What unstated premises are you relying on when conducting the investigation?
