t provides a definition of the term quicksand as sand that has been saturated with water to a certain degree. Many of the flaws in the incorrect options have to do with how this degree of saturation is described. A.The matter of degree is introduced with the word so, which is used to indicate that the relevant degree of saturation will be specified with a clause that states a condition—a statement that includes both a subject and a verb—that implies a certain degree ofsaturation. Lacking a subject, this sentence fails to state a clear condition. B.Correct. The clause introduced with that contains a proper statement—with both a subject and verb—which implies a degree of saturation with water. This sentence has none of the flaws explained above in answer choice A. C.The word (adjective) enough, which qualifies the word water is misplaced. In English (with exceptions), qualifiers of nouns are generally placed before the noun. In this case, it should be enough water. D.The words so as make this option a poor choice. Like answer choice D, if we cut out “so as” and write, “quicksand” is the term for sand saturated enough to acquire the character of a liquid, then our statement would be much improved. However, as it stands, answer choice D is at best awkward. E.This version is awkward—so much qualifies saturated, yet it is placed after the word water, well after saturated. This makes the statement unnecessarily difficult to read. A modification of this part of the sentence so as to read saturated so much with water would be an improvement. As explained above in answer choices A and B, this sentence would be better if as to acquire a liquid character were replaced with that it acquires a liquid character (or, as in answer choice B, that it acquires the character of a liquid).
