Salt deposits and moisture threaten to destroy the Mohenjo-Daro excavation in Pakistan, the siteof an ancient civilization that flourished at the same time as the civilizations in the Nile Delta and the river valleys of the Tigris and Euphrates.

(A) that flurished at the same time as the civilizations

(B) that had flourished at the same time as had the civilizations

(C) that flourished at the same time those had

(D) flourishing at the same time as those did

(E) flourishing at the same time as those were

我想问一下og上说 D的did， unnecessary 是不是只有主谓比较的时候就可以省略do，did 主谓宾的时候才不能省略？ GMAT中 I eat faster than you do。这样错误吗？谢谢！

D的did不是该不该省略的问题，是在这个结构中根本不该出现。因为前文没有与之对应的动词。

I eat faster than you.
I eat faster than you do.
Both are OK.
