Dear Friends,
Here is a detailed explanation to this question-
Bunuel
Technically, "quicksand" is the term for sand
that is so saturated with water as to acquire a liquid's character.
(A) that is so saturated with water as to acquire a liquid's character
(B) that is so saturated with water that it acquires the character of a liquid
(C) that is saturated with water enough to acquire liquid characteristics
(D) saturated enough with water so as to acquire the character of a liquid
(E) saturated with water so much as to acquire a liquid character
Meaning is crucial to solving this problem:Understanding the intended meaning is key to solving this question; the intended core meaning of this sentence is that quicksand is sand that is so saturated with water that it acquires the characteristics typically possessed by a liquid.
Concepts tested here: Meaning + Idioms + Awkwardness/Redundancy• "so as to" is generally an incorrect usage; "so + cause + as to + effect" and “so + cause + that + effect” are the correct, idiomatic usages.
• “enough + to” is a correct, idiomatic usage; besides, “enough” is used to show “adequacy” and generally not used to show a cause-effect relationship; rather, “so + cause + that + effect” or “so + cause + as to + effect” are some of the preferred constructions for conveying a cause-effect relationship.
A: Trap. This answer choice incorrectly uses the unidiomatic construction “so + cause (“saturated with water”) + as to + effect (“acquire a liquid’s character”)”; please remember, "so as to" is generally an incorrect usage; "so + cause + as to + effect" and “so + cause + that + effect” are the correct, idiomatic usages. Further, Option A uses the passive voice construction “a liquid's character”, rendering it awkward and needlessly indirect.
B: Correct. This answer choice uses the phrase “character of a liquid”, conveying the intended meaning – that quicksand is sand that is so saturated with water that it acquires the characteristics typically possessed by a liquid. Further, Option B correctly uses the preferred, idiomatic construction “so + cause (“saturated with water”) + that + effect (“it acquires the character of a liquid”)” to refer to the cause-effect relationship between the sand being saturated with water and the sand acquiring the character of a liquid. Besides, Option B is free of any awkwardness or redundancy.
C: Trap. This answer choice alters the meaning of the sentence through the phrase “liquid characteristics”; the construction of this phrase illogically implies that quicksand is sand that is so saturated with water that it acquires characteristics that are
liquid in nature; the intended meaning is that quicksand is sand that is so saturated with water that it acquires the characteristics
typically possessed by a liquid. Further, Option C uses the phrase “enough to” to refer to the cause-effect relationship between the sand being saturated with water and the sand acquiring the character of a liquid; please remember, “enough” is used to show “adequacy” and generally not used to show a cause-effect relationship; rather, “so + cause + that + effect” or “so + cause + as to + effect” are some of the preferred constructions for conveying a cause-effect relationship.
D: This answer choice incorrectly uses the unidiomatic construction “enough so as to”; please remember, “enough + to” is correct, idiomatic usage. Further, Option D uses “enough” to refer to the cause-effect relationship between the sand being saturated with water and the sand acquiring the character of a liquid; please remember, “enough” is used to show “adequacy” and generally not used to show a cause-effect relationship; rather, “so + cause + that + effect” or “so + cause + as to + effect” are some of the preferred constructions for conveying a cause-effect relationship.
E: This answer choice alters the meaning of the sentence through the phrase “liquid character”; the construction of this phrase illogically implies that quicksand is sand that is so saturated with water that it acquires characteristics that are
liquid in nature; the intended meaning is that quicksand is sand that is so saturated with water that it acquires the characteristics
typically possessed by a liquid.
Hence, B is the best answer choice.To understand the concept of "So As To" on GMAT, you may want to watch the following video (~1 minute):
