Hello Everyone!
Let's tackle this question, one thing at a time, and narrow down our options quickly so we know how to answer questions like this when they pop up on the GMAT! To begin, let's take a quick look at the question and highlight any major differences between the options in
orange:
With near to all tortilla chips made from corn kernels that have been heated in a solution of calcium hydroxide (lime), this removes the skin of the kernel so water can penetrate.
A)
With near to all tortilla chips
made from corn kernels
that have been heated in a solution of calcium hydroxide (lime)
, thisB)
Having nearly all tortilla chips
made from corn kernels
that are heated in a solution of calcium hydroxide (lime)
, thisC)
Nearly all tortilla chips
being made from corn kernels
that are heated in a solution of calcium hydroxide (lime)
D)
Nearly all tortilla chips
are made from corn kernels
that have been heated in a solution of calcium hydroxide (lime)
, a process thatE)
Nearly all tortilla chips
are made from corn kernels
having been heated in a solution of calcium hydroxide (lime
), a process thatAfter a quick glance over the options, we have several areas we can focus on to narrow down our options:
1. With near to all / Nearly all (Idioms & Clarity)
2. made / being made / are made (Construction & Active/Passive Voice)
3. that have been heated / that are heated / having been heated (Verb Form)
4. …,this / …, a process that / nothing (Modifiers & Construction)While it may be tempting to start with #1 and move down this list, we’re going to start with #4: modifiers & construction. Why? Because it’s essentially an either/or split, and it will eliminate 2-3 options rather quickly. We need to make sure that any modifiers have clear antecedents, the wording is clear, and that the lack of modifier in option C isn’t a problem:
A) With near to all tortilla chips made from corn kernels that have been heated in a solution of calcium hydroxide (lime), thisThis is
INCORRECT because “this” should refer back to ONLY the closest noun (calcium hydroxide) and not the entire previous clause (that have been heated in a solution of calcium hydroxide). Since “this” doesn’t cover as much as we need it to, this option is out.
B) Having nearly all tortilla chips made from corn kernels that are heated in a solution of calcium hydroxide (lime), thisThis is
INCORRECT for the same reason as option A!
C) Nearly all tortilla chips being made from corn kernels that are heated in a solution of calcium hydroxide (lime) removesThis is
INCORRECT because removing the modifier altogether creates an entirely different problem: subject-verb agreement! We’ve now made the singular verb “removes” our main verb, and our subject is the plural “tortilla chips.” So - let’s rule this one out too.
D) Nearly all tortilla chips are made from corn kernels that have been heated in a solution of calcium hydroxide (lime), a process thatThis is
OKAY for now. Starting the modifier with “a process that,” it’s 100% clear that it refers back to the previous clause, rather than just the previous noun.
E) Nearly all tortilla chips are made from corn kernels having been heated in a solution of calcium hydroxide (lime), a process that This is also
OKAY for now because “a process that” clearly refers back to the entire previous clause.
We can eliminate options A, B, & C because their endings created problems with construction and subject-verb agreement. Now that we have it narrowed down to only 2 options, the only list item we have left to tackle is #3: verb form.
D) Nearly all tortilla chips are made from corn kernels that have been heated in a solution of calcium hydroxide (lime), a process thatThis is our
CORRECT option! The sentence is structured clearly, and the verb “have been heated” shows the correct cause/effect relationship (corn kernels are heated in a lime solution → removes kernel skins).
E) Nearly all tortilla chips are made from corn kernels having been heated in a solution of calcium hydroxide (lime), a process that This is
INCORRECT. The verb “having been heated” is supposed to indicate both the cause & result of an event, whereas we only need a verb that indicates the cause of the event.
There you have it - option D is our winner! By focusing on an either/or split first, we were able to eliminate 3 options quickly, giving us more time to focus on more complex grammatical issues!
