W: Elizabeth Martin speaking.
M: Dr. Martin, my name is Mark Johnson. My roommate, Benjamin Jones, is in your art history class.
W: Yes.
M: Well, he is sick and won’t be in your class today. He asked me to bring his term paper to your office.
W: OK. The paper is due by 3 o’clock.
M: I have a class from 1 to 2. I’ll bring it to your office after my class.
W: Well, I have a meeting this afternoon. So you can drop it off with the secretary of the art history department. She’ll see that I get it.
M: Ok. Oh I ’almost forgot. I’m a biology major. But my advisor told me that I need one more course to graduate. I’ve noticed that you are teaching a course on color painters next semester. Could tell me a little bit about it?
W: Sure. Well, it’s a course for non-art majors. We’ll be looking at several different painters and examining their works. We’ll also look the history and politics of the era in which they lived.
M: That sounds interesting. What else is required?
W: There is no final exam. And there is only one required book. But each student has to give a major presentation a- bout the individual painter at the end of the course.
M: Thanks.
