85.  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 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

为啥不能用过去完成时， 逻辑上过去的过去已经繁荣， 但是这个过去的过去的时间和civilizations in the Nile Delta 是同样的时间？ 而且had又平行。 谢谢，。

谢谢。

过去完成时不对，是因为这里没有需要比较时间先后的时间状语或逻辑意思。而且，B选项中，后面的那个had多余了。

我只能说，没有必要用过去完成时。
现在时表示现在有threaten，那么往前，过去式已经可以了。
