W: Professor Jones, May I interrupt you for a moment?
M: Of course, Alice. Come in and have a seat. I have about a half hour before my faculty meeting. Let me move this chair closer to my desk.
W: Thanks. I’ve come to talk to you about my grade on my last economics project. I want to know why I was given an "F. "
M: Well, Alice, your approach was so similar to that of another student in the class that I seriously doubted that you’d done the calculations yourself.
W: I did work closely with my roommate Betty, but let me explain why. A week before the project was due, I was too sick to do my research. Betty agreed to help me with the project the night before it was due. We stayed up all night in order to finish it on time. The calculations were really my own.
M: Well, you’d been given a month to work on the project. Wouldn’t it have been better to get a head start rather than to wait until the last minute? Each student was supposed to prepare this project individually. I’m afraid that my decision remains the same. However, next week we will be studying the government’s role in running the economy. If you’re willing to make an oral presentation about the subject, I’ll give you extra credit.
W: Thank you, Professor Jones. I’ll have my oral report ready for class on Friday.
