OG 117(黄色)

117. New theories propose that catastrophic impacts of asteroids and comets may have caused reversals in the Earth's ma^gnetic field, the onset of ice ages, splitting apart continents 80 million years ago, and great volcanic eruptions.

(A)         splitting apart continents

(B)         the splitting apart of continents

(C)        split apart continents

(D)        continents split apart

(E)         continents that were split apart

这题选B,其实我觉得B 是对的,但是BY上面说过,如果这个动词本身有动作性名词,要优先用动作性名词,而不是the +Ving形式.我吧这套题里面的SPLIT当作动作性名词了,所以误选C , 有哪位牛人能告诉为什么这里不能用C,谢谢啊 

简单点，

因为一个有of 一个没of。
