OG12 85 关于the same as的疑问

hoteldeville

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

首先，我感觉，这道题不是the same as的比较idiom吗，因为有at和tim，at the same time看着像一个状语?
其次，句子结构划线部分是that引导的限制性定语从句吗？
最后，as后面到底有没有省略did？或者省略了flourished？

IESE

我感觉，这题考的是the same 搭配 as 的用法~
as 作 pron.代词 与 the same 连用， 引导定语从句。
例：I live in the same place as Tom (does) 我和汤姆住在同一处。
引自《英汉大词典》陆谷孙
at the same time 应该是状语吧！
其次，我觉得that 应该是 限制性定语从句
最后，我觉得 as 后面省略了 did 也就是 flourished 的意思~

lz 有木有觉得 the site of 到后面都是同位语呀~ 不知道我理解对不对 lz确认一下~
