A、A study group. B、A history exam. C、The man’s painting. D、A professional artist. C综合推断题，结合听力材料可知，对话一直围绕男士的画作展开，所以C正确

W: Hi, Mark. I didn’t know you could paint.
M: Well, I’m just learning. It’s for my studio art class.
W: It’s pretty good for a beginner.
M: Oh thanks, Judy. The instructor really liked my schedules, but she hasn’t seen my painting yet.
W: Eh, there seems to be something wrong with it though.
M: Yeah, I know what you mean. It doesn’t look right to me either.
W: I think I know. Look here at the sky, it just seems to fill in with other colors of painting.
M: What do you mean? Everyone knows the sky is blue,
W: Well, that depends. Sometime it is and sometime it isn’t, as sunset can be full of reds and purples. Well, even now, take a look now Mark, what do you sec?
M: It looks blue to me.
W: Look again. Do you see a kind of tannish color?
M: Oh yeah, I see what you mean.
W: By adding some tan to your sky, I think you’ll get a more accurate picture, and the color will look more natural.
M: I think I’ll try that. Gee, how did you get to know so much about painting? Have you taken a lot of courses?
W: No, actually. But my father is an artist.
M: A professional artist?
W: Oh yeah.
M: I wish we could talk some more, Judy. How about going for a cup of coffee? I’m ready for a break.
W: I’d love to. But I have to take a history exam. In fact, I was just on my way to the classroom, and I think I am already late. Maybe tomorrow.
M: Great, I’ll meet you at the students’ center after my class. A little after three, ok?
W: Sounds good. Got to be going now.
M: Bye, Judy.
