og sc 99請問各位前輩一個笨問題...

99. New theories propose that catastrophic impacts of asteroids and comets may have caused reversals in the Earth’s magnetic 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 continent

(D) continents split apart
(E) continents that were split apart

答案是D。没有疑问。
但是og里面说：in E, continuents illogically replaces the splitting in th series:although the impacts in question may have caused continents to spliot, they did not cause those continents that were spilit apart 80 million years ago to materialize.
这里是什么意思？
THX.
