请教一道GMATPrep语法

flyawayaloe

我觉得按照OG的宗旨，E是应该强烈排除的啊。As would be the case一定会被OG认为wordy and awkward。谁能解释一下啊。

flyawayaloe

忘传图片了。

flyawayaloe

晕 图片还是没传上来。

Like any star of similar mass would do, once the Sun has exhausted the hydrogen in its core, it expands in to a red giant, eventually ejecting its outer envelope of gases to become a white dwarf.

其他答案没争议。关键是D和E. 正确答案是E. 虽然我觉得两个答案都有毛病，但E那个As would be the case我一看到就排除了，明显不符合OG的宗旨啊。

D. As any star of similar mass would, once the hydrogen in the sun's core is exhausted it will expand into a red giant and will eventually eject
E. As would be the case with any star of similar mass, once the sun exhausts the hydrogen in its core, it will expand into a red giant and eventually eject.

As is the case is commonly used in English.

D的主语是 hydrogen,后面的it指代不明.
