733. The distribution of mass within the core of the Earth, like the mantle that surrounds the core, has been deduced from the orbital behavior of the Earth and the motions of satellites controlled by the gravity of the Earth.
(A) the mantle that surrounds the core
(B) that within the mantle surrounding the core
(C) that of the mantle surrounding the core
(D) the mantle the core surrounds
(E) the distribution of mass within the mantle that surrounds the core

答案b，E错在哪里？

请教the mantle surrounding 引导的是限制型定语从句还是非限制型定语从句？

According to the "concision" principle of gmat, "that" in B is more succinct than "the distribution of mass" in E.

"surrounding " is the participle representing the estate of "mantle".

The subordinate clause is not appropriate to be used under this the situation ,which means "once happened."

B. that = distribution of mass

mantle surrounding the core > mantle that surrounds the core

存粹是为了简洁。楼上所述定语从句表示 "once happened" 不知可有详述？谢了.

版版客气。偶的石林上课笔记里有一句：定语从句中的TO DO动词表示一次性发生的动作，表示反复发生的动作或存在的状态要使用分词结构。

这不是定语从句，是分词结构。
