請問pp2 Q41 listening

41.M: I just want to work in Dr. Cole's literature class.
W: Really? I was beginning to think I was the only one.

What does the woman mean?
A. She think the course is easy
B. She has a lot of work to do
C. She is thinking about taking literature
D. She is taking only one class

答案是 B

不過我不是很能理解,有人能解釋給我聽嗎?
總覺得C的答案還比較合理,因為work也可以解釋為他想拿literature那堂課不是嗎?
還是答案錯了 @_@

謝謝

感觉应该是C，不过不是太吃得准work in的意思，这里好像是插班上文学课的意思。W的回答大概是说她原来以为就她一个人（插班上这门课？）

C应该是直接基于W的话可以推出的意思，其他几个意思感觉不准确。

欢迎讨论。
