OG 120解释中没提到的一点

120. The Parthenon was a church from 1204 until 1456, when Athens was taken by General Mohammed the Conqueror, the Turkish sultan, who established a mosque in the building and used the Acropolis as a fortress.

(A) who established a mosque in the building and used the Acropolis as

(B) who, establishing a mosque in the building, used the Acropolis like

(C) who, when he had established a mosque in the building, used the Acropolis like

(D) who had established a mosque in the building, using the Acropolis to be（A）

(E) establishing a mosque in the building and using the Acropolis as

Choice A, the best answer, correctly supplies the past tense verbs established and used to describe two actions performed in 1456; also, it idiomatically employs the phrase used the Acropolis as a fortress, in which used as means "employed in the capacity of." Choices B and C incorrectly replace as with like. Furthermore, in C, when he had established a mosque distorts the intended meaning by stating that the first action was completed before the second was begun. Similarly, in D, had established... using states that Mohammed had already performed the actions before capturing Athens; and in E, establishing and using modify Athens, thus producing an absurd statement. In addition, D includes the unidiomatic construction "using x to be y."

ETS的解释中没说B,C中who,的说法是否正确。难道这种把句子分的支离破碎的形式也对吗？

请教各位。谢谢。

Conqueror=the Turkish sultan

the Turkish sultan为插入语，解释Conqueror。

who定于从句修饰Conqueror，分开是因为插入the Turkish sultan。

就是这个道理

不是把句子拆的支离破碎而排除它的，是它改变了原句的逻辑意思。

who, establishing a mosque in the building, used the Acropolis like明明establish和use是并列的从句谓语，但是这样以来就把used作为从句谓语，而establishing就变成从句的状语修饰了。GMAT语法最忌讳改变原句的重心和逻辑愿意，只有在不得已的情况下才可以。
