you mistyped the "as" in key A, right?
(i) "those" has no logical referent in the former part of the sentence - "those" can't refer to "civilization" which is singular.
(ii)if you choose d, what does "did" refer to? the "flourishing" is not a verb.
Remember: "did" can be emited in this case. There are so many such cases in GMAT and lucylu has pointed out many times in posts on this board |
