The original sentence begins with a modifier "Responding to growing demand for high-end vehicles,"
but this modifier has no logical subject within the main clause. The subject of the sentence should be
the people or organizations that respond to this growing demand.
Moreover, the pronoun "they" is ambiguous, as it could grammatically refer either to the interiors or to
the models. We know that the intended antecedent of "they" is the “cars”, so we need to find a choice
that makes this intention clear. Finally, the modifier "that are so luxurious" should be placed
immediately after "interiors," not "models"; otherwise, an alternative phrasing without this modifier
should be found.
(A) This choice is incorrect as it repeats the original sentence.
(B) The choice repeats the original modifier error: the subject of the modifier is not present in the
sentence.
(C) This choice repeats the original pronoun error: "they" is ambiguous and could refer to either
interiors or models. Also, the modifier "that are so luxurious" is placed incorrectly.
(D) This choice repeats both the original modifier error and the original pronoun error. Also, "interior"
should be plural.
(E) CORRECT. This choice correctly introduces "auto makers" as the subject of the sentence and
also corrects the pronoun error by replacing "they" with "these cars." Note that the use of the
synonym "cars" avoids both the awkward repetition of "models" and the ambiguity of the pronoun
"they."
