Salt deposits and moisture threaten to destroy the Mohenjo-Daro excavation in pakistan, the site of 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 flourished 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

我知道bcde的错误,可觉得a少了did也是错的.哪位大牛帮我解释解释
谢了先

为什么不是that flourished at the same time as did the civilizations
thanks

曾有过同样的困惑，我是这样理解的：the same as 结构中只要对比的部分是正确对应的就行了，而不需要是完整的结构。as ...as才需要完整的结构。

请NN说说。
