[求助]og-80

80。Salt deposits and moisture threaten to destroy the Monhenjo-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.

The answer is A, but I am confused, why not "that flourished at the same time as did the
civilizations"

the same A as B, 比较的是A and B?

这句话比较的是什么，是 the site of an ancient civilization 和civilizations in the Nile delta and the river valleys of the Tigris and Euphrates吗？不大象啊。

That's right, because two sentences have the same verb, flourished.

哪位NN可以分析一下这句话马？意思大致懂了，但是对于句子结构还是不明白
