E. heavily, which accounted for two-thirds of the increase in consumer spending on housing and health care, with the remainder of it comingThis question has to do with verb tenses and concise wording. We need to make sure the verb used make logical sense, and we need to make sure the verbs aren’t being turned into other parts of speech, such as modifiers, appositives, or other problematic issues. The GMAT also always wants test takers to eliminate overly wordy answers. Let’s see how each option breaks down:
A. greatly accounts for two-thirds of the increase in consumer spending on housing and healthcare, the rest of which came This is
incorrect. “accounts” is the wrong verb tense. Increases refers to the subject, PCE, which is plural and accounts is singular. Also, the phrase “the rest of which came” is also vague - it’s not 100% clear if that’s referring back to the increase, housing, or healthcare.
B. greatly were what accounted for two-thirds of the increase in consumer spending on housing and health care; the rest of the increase comingThis is
incorrect. This sentence is overly wordy. “Where what accounted for” is not needed when “accounted for” has the same meaning. The phrase after the semicolon is also not a complete sentence because it lacks a proper verb (it should be “came” instead of “coming). It does, however, fix the vague phrasing from option A to make sure we know the phrase is referring back to the increase - so let’s look for more options that do this.
C. greatly accounted for two-thirds of the increase in consumer spending on housing and health care; the rest of the increase cameThis is
correct. This is the most concise answer and uses the correct past tense “accounted for.” It also makes the ending of this option clear to readers that it’s referring back to the increase.
D. greatly, accounting for two-thirds of the increase in consumer spending on housing and health care, while the rest of the increase cameThis is
incorrect. Changing “accounted for” to “accounting for” turns the verb into a modifier, thus creating a fragment because there is no verb for the subject “increases.”
E. heavily, which accounted for two-thirds of the increase in consumer spending on housing and health care, with the remainder of it comingThis is
incorrect. Changing “accounted for” to “which accounting for” turns the verb into a modifier, thus creating a fragment because there is no verb for the subject “increases.” The phrase “with the remainder of it coming” is also vague - it’s not 100% clear what the pronoun “it” is referring back to (the increase, consumer spending, housing, health care??).
There you have it - option C is the correct choice!Don't study for the GMAT. Train for it.
