M: Good morning. Say, do you know what the assignment is for our! term paper in history?
W: Sure. Weren't you in class on Monday? That's when it was given out.
M: No, I missed that class. Was there a handout?
W: No, the instructor just wrote the assignment on the board.
M: Could I copy the assignment from your notes?
W: You could, ff I had copied it all down; but I just wrote down the part that I wanted.
M: Oh, no.
W: You see, there were four choices of topics ior the term paper; but, when I saw them, I knew which one I wanted so I didn't copy the others down.
M: Can you remember any o'f the others?
W: Let's see. There was one about World War I, something about it, but I don't remember what, and there was one called "the idea of progress in the nineteenth century."
M: And what was the last one?
W: I can't remember. My mind is a complete blank. Maybe you can ask someone else.
M: Yes, I will. Anyway, those are certainly broad topics.
W: Yes, but you van focus on a special area within them. Which one would you take?
M: Of course, I don't know what the last one is, but of these three, I think I'd take "the idea of progress."
W: That's very abstract.
M: Yes, but it's one of my interests and I've read a lot on the subject. I've never written a term paper on it though.
W: Me neither. I haven't even read about it. Are you going to class on Wednesday?
M: Yes.
W: Maybe he'll write it on the board again.
M: I hope so. Good luck with your paper.
W: Same to you.
