85. Salt deposits and moisture threaten to destroy the Mohenjo-Daro excavation in Pakistan, the site of an ancient civilization "that ?ourished at thesame time as the civilizations" in the Nile Delta and the river valleys of the Tigris and Euphrates.
(A) that ?urished at the sametime as the civilizations (B) that had ?ourished at the sametime as had the civilizations (C) that ?ourished at the sametime those had (D) ?ourishing at thesame time as those did (E) ?ourishing at thesame time as those were
对CDE的解释都提到 Plural pronoun "those" cannot refer to the singular "civilization" and thus lacks a referent. 那么倘若我们比较的是A 和B两个civilization, 而非现在的A和B, C, D......., 然后把those 改称that就可以吗?用that refer to 前一个civilization?
