想请教一下85题

1. 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


仅对动词时态而言，解释中说，由于过去完成时需要发生在一个动作之前，可是flourish这个动作确实发生在主句的threaten之前啊～
请牛牛们解释。


谢谢～～～

I suppose B is the proper answer in this case.
the Mohenjo-Daro excavation in Pakistan and the site 应该是同位语。SITE应该是进一步说明EXCAVATION的。所以这里应该用过去完成时去形容发生过的事。

to 楼上的，OG说原句正确，解释说B不正确的原因是因为had flourished这个时态需要一个前面发生的动作。。。

flourish仅仅发生在过去，用定语从句比较好。
B中的完成时没有必要。
DE中的分词表正在进行或者伴随，是不对的。
the same... as固定搭配，C错
关于正确答案A, 可以理解为：that flourished at the same time as (did) the civilizations.
