Meaning is crucial to solving this problem:Understanding the intended meaning is key to solving this question; the intended meaning of this sentence is that many of the earliest known images of Hindu deities in India date from the time of the Kushan empire, and the images were fashioned either from the spotted sandstone of Mathura or from Gandharan grey schist.
Concepts tested here: Meaning + Modifiers + Parallelism• In a “noun + comma + phrase” construction, the phrase must correctly modify the noun; this is one of the most frequently tested concepts on GMAT sentence correction.
• “neither A nor B” and “either A or B” are idiomatic uses and are only used when referring to two elements; A and B must be parallel.
• Any elements linked by conjunction must be parallel
A: This answer choice incorrectly modifies "the Kushan empire" with "fashioned either...grey schist", illogically implying that the Kushan empire was fashioned either from the spotted sandstone of Mathura or from Gandharan grey schist; the intended meaning is that many of the earliest known images of Hindu deities in India were fashioned either from the spotted sandstone of Mathura or from Gandharan grey schist; please remember, in a “noun + comma + phrase” construction, the phrase must correctly modify the noun. Further, Option A fails to maintain parallelism between A ("from the spotted sandstone of Mathura") and B ("Gandharan grey schist") in the idiomatic construction "either A or B"; please remember, “neither A nor B” and “either A or B” are idiomatic uses and are only used when referring to two elements; A and B must be parallel.
B: This answer choice incorrectly modifies "the Kushan empire" with "fashioned from either...grey schist", illogically implying that the Kushan empire was fashioned either from the spotted sandstone of Mathura or from Gandharan grey schist; the intended meaning is that many of the earliest known images of Hindu deities in India were fashioned either from the spotted sandstone of Mathura or from Gandharan grey schist; please remember, in a “noun + comma + phrase” construction, the phrase must correctly modify the noun. Further, Option B fails to maintain parallelism between A ("the spotted sandstone of Mathura") and B ("from Gandharan grey schist") in the idiomatic construction "either A or B"; please remember, “neither A nor B” and “either A or B” are idiomatic uses and are only used when referring to two elements; A and B must be parallel.
C: This answer choice incorrectly modifies "the Kushan empire" with "either fashioned..grey schist", illogically implying that the Kushan empire was fashioned either from the spotted sandstone of Mathura or from Gandharan grey schist; the intended meaning is that many of the earliest known images of Hindu deities in India were fashioned either from the spotted sandstone of Mathura or from Gandharan grey schist; please remember, in a “noun + comma + phrase” construction, the phrase must correctly modify the noun. Further, Option C fails to maintain parallelism between A ("fashioned from the spotted sandstone of Mathura") and B ("Gandharan grey schist") in the idiomatic construction "either A or B"; please remember, “neither A nor B” and “either A or B” are idiomatic uses and are only used when referring to two elements; A and B must be parallel.
D: This answer choice fails to maintain parallelism between the verb phrase "date from the time of the Kushan empire" and the noun modifier "either fashioned from...grey schist"; please remember, any elements linked by conjunction must be parallel. Further, Option D fails to maintain parallelism between A ("fashioned from the spotted sandstone of Mathura") and B ("from Gandharan grey schist") in the idiomatic construction "either A or B"; please remember, “neither A nor B” and “either A or B” are idiomatic uses and are only used when referring to two elements; A and B must be parallel.
E: Correct. This answer choice avoids the modifier error seen in Options A, B, and C, as it uses the active verb phrase "were fashioned", rather than a modifying phrase; this usage conveys the intended meaning - that many of the earliest known images of Hindu deities in India were fashioned either from the spotted sandstone of Mathura or from Gandharan grey schist. Further, Option E maintains parallelism between the verb phrases "date from the time of the Kushan empire" and "were fashioned". Additionally, Option E correctly maintains parallelism between A ("from the spotted sandstone of Mathura") and B ("from Gandharan grey schist") in the idiomatic construction "either A or B".
