问题补充：

She is a woman of great knowledge, much can be learned.

A. in whom

B. about whom

C. of whom

D. from whom

答案：

A. in whom

B. about whom

C. of whom

(答案→)D. from whom

解析：考查定语从句中的;介词+which/whom引导的定语从句，因为先行词是knowledge，所以用which，又因为定语从句中的动词是learn，应该和from搭配，所以选D，句意是：她是知识渊博的女性，有很多可以学习的东西。选D。
