A、Have lunch with her right now. B、Go home with her right now. C、Take the final exam seriously. D、Be optimistic about the exam.

M: How did you do on the exam?
W: I passed, but I didn’t do so well. The essay question was the worst part for me. How about you?
M: I did all right on everything except the essay question too. I wasn’t really prepared to write about the tribe in the rainforest of Brazil. We studied the rainforest for only a few days. I didn’t think it would be on the test.
W: Me either. I thought for sure he would ask us something about the Incas in Peru or maybe the mountain people in Chile. I studied most of the material on those groups and didn’t spend much time on the people of the rainforest. Do you know how much the exam counts towards our final grade?
M: I think it’s 30％ .
W: Thirty percent! Oh no, I’m in deep trouble this time! That means I’ll have to get A’s in everything else to get a decent grade.
M: That may not be too hard. We’ve already gone through most of the readings the class is supposed to cover. After next week it will just be the review. But then there is the final paper, of course.
W: Yes, I was hoping to do well on this test so I could relax when writing my paper, but now it looks like I’ll have to spend more time preparing to write that paper.
M: Well, I will too. Hey, I’m kind of hungry. I think I’ll go and get some lunch. Do you feel like joining me?
W: I’d love to, but I think we’d better go home and study harder right now. We must take the exam seriously.
M: OK, see you later.
