For a question such as this one, how do we know whether "that" is acting as a modifier to describe "enslavement" alone or "devastation and enslavement". I marked A because I thought that "that" jumps over the prepositional phrase to modify enslavement alone, and choice E is wrong because "the devastation and enslavement" seems to be a singular entity.
Please help. Thank you
Good question! Because the GMAT cannot ask us to read minds, we have to use context clues and logic to guide us.
Take another look at (E):
Quote:
…
the devastation and enslavement in the name of progress
that have decimated the native peoples of the Western Hemisphere.
While we can't know what the author intended, we can see that the verb "have" is plural, and so the phrase beginning with "that" must modify a plural noun. The only possibility here is the compound noun phrase, "the devastation and enslavement"; otherwise, we’d have a subject-verb agreement problem otherwise, since “… enslavement that
have decimated" doesn’t work at all.
Contrast this with (A):
Quote:
…devastation and enslavement in the name of progress
that has decimated native peoples of the Western Hemisphere.
Now "has" is singular, meaning we need “that” to modify a singular noun. So at the very least, the phrase “that has decimated native peoples” can’t modify “devastation and enslavement”, since that pair of nouns would require a plural verb.
So what are our options for singular nouns? The closest preceding singular noun is "progress." But it doesn't make any sense to write that "progress" decimated peoples.
I suppose you could argue that “that has decimated native peoples” modifies only “enslavement.” But that requires a huge logical contortion: in order for "that" to refer only to "enslavement," we'd have to convince ourselves that "that" somehow jumps over "progress" and then refers to only one of two items in a compound noun construction (“devastation and enslavement”). That’s pretty far-fetched.
If finding an antecedent requires that much logical contortion, it's a good bet that we're over-complicating things -- we want the correct answer to be as clear as possible.
The simplest interpretation of (A) is illogical, and so (E) is clearly better.
I hope that helps!
