Salt deposits and moisture threaten to destroy the mohenjo-Karo excavation in Pakistan,the site of an an ancient civilizationthat flourished at the same time as the civilizations in the Nile delta and the river valleys of the Tigris and Euphrates.

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

（C）those不對，had不對
those不能只帶civilizations，因為前面civilization是單數；had要改成did，要不就認為是perfect tense了
（D）flourishing可以，但是後面的those和did錯了。
those錯同C，did的話前面沒有對應的詞，如果想did對應flourish的話，只能使用flourished
（E）錯同D

those~~~指代不清！
至于现在分词那个问题：我想说的是不可以随意更改A 句中的逻辑含义和修饰层次，A从句修饰不该随意更改，除非有明显语法错误。
如果换成ing修饰，违背了A句所要表达的逻辑层次，所以D E杀
