When preparing for an endurance race such as a triathlon, athletes must run and swim long distances, train themselves to master boredom and mental fatigue, and consume highly nutritious food to provide enough energy to sustain their bodies during the intense physical stress of the training period.
A. highly nutritious food to provide
B. highly nutritious foods for providing
C. food that is highly nutritious, and which provide
D. highly nutritious food that provide
E. foods which is highly nutritious in order to provide
Whenever I read these SC sentences, I like to comb through the original sentence itself to spot any glaring errors before I jump into the responses. Here, the barebones main clause says that
athletes must run and swim, train themselves, and consume food. The
why comes right after the underlined portion, and notice how
to sustain matches the earlier infinitive explanation in
to master boredom. The GMAT™ question-writers love parallelism in its many forms. In other words, I see nothing wrong with the original sentence. However, it can be a good idea to
disprove other answers sometimes in order to feel stronger about selecting (A), not to mention that there just might be another response that somehow expresses the same idea in a more concise manner. So, where do the other answers fall short? My take on each:
(B)
for providingAnalysis: Why use the preposition
for and an -ing form of the verb when there is no earlier example? In fact, as I pointed out above, that earlier example of an action followed by an explanation uses
to instead:
train themselves to master boredom. Look to the non-underlined portion for clues--they are usually there.
(C)
and which provideAnalysis: The
which clause is unnecessary and wordy, and
provide is supposed to modify
food, not
foods. A singular verb agreement is needed.
(D)
that provideAnalysis: This follows the same subject-verb agreement trap from choice (C). If it was incorrect there, then it must be incorrect here.
(E)
foods which isAnalysis: The answer is long-winded for starters, and since the extra words add nothing in the way of clarity, a shorter answer is stronger. This one opts for the opposite subject-verb agreement problem, pairing the plural
foods with the singular
is. But even before that, the
which clause in Standard American English indicates non-essential information, and for this reason, it should use a comma before it. Observe the following model sentences and how the meaning changes based on essential versus non-essential clause triggers (i.e.
that versus
which):
Sentence 1:
The book that was on the table was red.Meaning: The person reading or hearing this information needs to know that the red book was on the table, or that the book that was on the table was red instead of some other color.
Sentence 2:
The book, which was on the table, was red.Meaning: The person reading or hearing this information needs to know that the book was red, but the information about its location is just tossed in to satisfy any curiosity about where that red book was spotted.
I want to emphasize again that this
that versus
which issue is not something most Americans adhere to consistently, but that in
Standard American English, the type that is tested on the GMAT™, such a distinction is, indeed, necessary.
Good luck with your studies.
