W: Elizabeth Martin speaking.
M: Dr. Martin, my name is Mark Johnson. My roommate, Benjamin Jones, is in your art history class.
W: Um, Art History 502?
M: Yes. 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 humanities course to graduate. I’ve noticed that you are teaching a course on landscape painters next semester. Could you 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 at 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 about an individual painter at the end of the course.
M: Hmm, it sounds good. Will you be in your office later today? I’d like to talk to you some more.
W: Well, my meeting’s scheduled to last all afternoon. Why don’t you stop by tomorrow any time in the afternoon? My office is in the Fine Arts Building right next to the library.
