W: Dr. Anderson, could you please clarify the requirements for this course? Some of us are a little bit confused about the final examination.
M: Oh? Well, you have two options in this course. You can either take a final examination or you can write a research paper instead.
W: Excuse me, Dr. Anderson. That’s the point I need you to clarify. What kind of research paper do you have in mind? A study? A report? A book review, perhaps?
M: A report. A summary really based upon current research in the field.
W: How long should the report be?
M: Length is really not important. I should think that it would take at least ten pages in order to develop the topic, however.
W: And should we check the topic with you before we begin writing?
M: You may, if you wish. But the only requirement is that it relates to current trends in the United States’ foreign policy. Are you considering writing a paper, Jane?
W: I’m not sure. I think that I’d like to know a little bit more about the examination.
M: All right. One hundred multiple-choice questions covering both the lectures and the outside readings.
W: Didn’t you say you would give us one hour for the examination?
M: Yes, I did.
