OG.NO.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 continents

D)                     continents split apart

E)                     continents that were split apart

My question: The right answer is B but why the E choice is wrong? Thanks a lot.

Additional question: how to understand the sentences below? In E, continents illogically replace the splitting in the series: although the impacts in question may have caused continents to split, they did not cause those continents that were split apart 80 million years ago to materialize.

E并列的成分不对。

虽然碰撞可造成大陆的分离，但不会达成大陆实际形成。所以E是illogically

parallelism:



reversals in magnetic fields


the onset of ice ages


the spliting apart continents


great volcanic eruptions


Although choice E does provide a noun, but with a subordinate clause, it is awkward.

再次引用我不明白的内容。虽然楼上两位朋友的解释我明白，也知道从句特别是被动语态的运用比较笨拙不符合GMAT的主动优先原则，但是还是想彻底弄明白上面我再次引用的OG的英文解释，大家都说OG是GMAT的SC的圣经，所以自由想把OG的每个相关解释彻底弄明白，再次感谢大家的宝贵帮助

irenelj78

the splitting apart of continents 80 million years ago这个选项cause 的宾语是splitting apart
continents that were split apart 80 million years ago这个表达cause的宾语是continents

而impacts of asteroids and comets 不可能会cause continents的，也就是说它们的影响不能引起80million年以前分离的continent的形成(they did not cause those continents that were split apart 80 million years ago to materialize。)
，而只能会cause "split" 这个动作，也就是只能引起这些大陆的分离。所以说continents  replace the splitting in the series,是不合逻辑的！！！

我这莫说不知道说的是不是明白？简单说就是：impact只能引起物质（continent）的分离，而不能引起物质（continent）的形成。
