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

如果D的those 改成its 对么？为什么OG上说did  awkward？为什么不要？不是civilizations flourished 么？

首先弱弱地说一句~楼上很漂亮啊~
我觉得这题选A，对吗？？CDE我觉得都不对，应该是it才对

recoupsin

a是对的。d就算是改了也不对。
