This GMAT verbal practice question is a sentence correction question testing your understanding of Pronouns - Ambiguity of Reference; Comparison Error.
Question 3: Thieves steal Hondas and Toyotas from the 1990s more than other models because they can chop them up and sell them for parts that are worth more than the car.
Looking for differences in the options, we can see that some of the options use the verb “dismantle” while others use the verb “chop”.
Also, the initial part of the answer options following the construction “more than ... varies across the options. Finally, some options use the construction “sell the parts” and some use “sell them for parts”.
The sentence is comparing the propensity of the thieves to steal Hondas and Toyotas. The correct construction should therefore compare the action of stealing Hondas and Toyotas with the action of stealing other models. The sentence should compare verbs (and use the verbs on both sides of the comparison). The correct construction would be “more than they steal other models” or “more than they do other models”.
In the construction “sell them for parts”, the pronoun “them” is ambiguous. It is not clear whether the pronoun refers to the “Hondas and Toyotas” or to “other models”. When a pronoun can be replaced with more than one of the nouns in the sentence, it leads to a pronoun reference ambiguity. We do not know which noun is the pronoun referring to. Such an ambiguity cannot be allowed.
The verb “chop” would mean to “cut something into pieces using a blunt instrument”. Therefore, the verb “dismantle”, which simply means to “take something apart” would be more appropriate in this context.
Choices (A) and (D) can be eliminated for any and all of the reasons discussed. The comparison is incomplete, the pronoun is ambiguous, and the verb “chop” is inappropriate.
Choice (B) corrects the comparison error. However, the pronoun usage is still ambiguous.
Similarly, choice (E) corrects only the pronoun error. The comparison construction is incorrect as it compares a verb to a noun.
