对于那道题，我一直在矛盾中，倾向于修饰sources，主要是从单复数考虑，但是又觉得
fainter似乎修饰light更好，而且detect的宾语是light更好些。
看来是一道无奈的题，希望考试的时候不要同时给that that和those that两个选项。

我现在确定是修饰sources了，原因是OG对80题的解释：
80. 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
In choices C, D, and E, the plural pronoun “those“ has no plural noun to which it can refer. 也就是说如果前面是单数civilization,后面不能用those代替，必须用civilizations. 同理，
those不能指代light, 即使those表示的是lights，也是ETS不prefer的结构，按ETS的逻辑，应该补出lights.
终于明白了！

谢谢楼上的朋友们，这么详细的分析，我还要好好琢磨一下，彻底搞透，不懂就再唐僧的问各位朋友，呵呵！
