请教一道PPreview的听力

题目听懂了，但是选错了，看了答案还是不理解。请教一下，万分感谢。

M: I just want to wish work in Dr. Cole’s literature class.

   W: Really!  I was begining to think that I was the only one.

   What does the woman mean?

   She thinks the course is easy.

   She has a lot of work to do.

   She is thinking about taking literature.

   She is taking only one class.                                                            B

这道题用排除法作比较好！个人觉得这是一种习惯，只有把它硬记下来了！

为什么C不对呢，那个女生说:"我以前觉得我是唯一想上literature课的人"。I was begining to think that I was the only one who wanted to take the literature class.

请再指点！呵呵
