请问听力PP-T-2-2-10

      classes.

   W: Well, you would think so.

    What does the woman imply?

   A   She is taking only one class this semester.

   BHer sociology course is very time-consuming.

  C She agrees with the man.

   DThe man should take an independent-study course.                     

女的说的Well, you would think so.是同意男的还是不同意男的呀？

不是 B 吗?

请牛人解释, 谢谢~

这句话的语气比较特别.

意思是:是吗?这(只)是你的看法啊,或者说,你可以这样认为啊(言外之意我不这样看),不知道这样理解对吗,请高手指正.
