• The question and optionsQuote:
The legal considerations that have forced some universities to revise their affirmative action admissions programs are similar to
the revisions that certain large businesses have recently made to their affirmative action hiring practices.A)
the revisions that certain large businesses have recently made to their affirmative action hiring practices
→ Legal considerations and revisions are not similar.
Considerations are things you should think about when making a decision; legal considerations require you to think about what the law requires or forbids and to act accordingly.
Legal considerations may instigate or spur changes, but they are not themselves changes or policies (or changes to policies).
Revisions are actual changes to a policy.
The two things under comparison are not similar.B)
the affirmative action hiring practices that certain large business recently have revised
C) those that have recently forced certain large businesses to revise their affirmative action hiring practices
D)
those recent revisions that have been made by certain large businesses to their affirmative action hiring practices
E)
what certain large businesses have done to their affirmative action hiring practices [READ: REVISIONS] in the recent past
From here and in this section, I am quoting Kaplan's answer writer, mostly verbatim.
→ Step 1: Read the Original Sentence Carefully, Looking for Errors
Are similar to in the original sentence indicates a comparison.
You must make sure that similar elements are being compared.
Whenever you recognize a comparison, cut through the filler until you’ve assessed whether the elements being compared are logically and grammatically similar.
This sentence begins with "legal considerations … are similar to … ," so what follows should also be "legal considerations" (or something very similar).
→ Step 2: Scan and Group the Answer Choices
(A) begins with
revisions. (B) begins with
… hiring practices. (C) and (D) begin with
those, a word that
could [my emphasis] refer to
legal considerations. (E) begins with
what certain large businesses have done.→ Step 3: Eliminate Choices Until Only One Remains
→
Revisions and
practices aren’t comparable to
legal considerations, so eliminate (A) and (B).
→ Choice (D) begins with “those,” but if you read further, you’ll notice that (D) uses
those recent revisions, which are not comparable to
legal considerations,. Eliminate (D).
→ Finally, option (E) is unclear and doesn’t provide a specific noun to compare to
legal considerations.[End Kaplan]
Furthermore, the noun clause (substantive clause, nominal clause) "what businesses have done" describes actions (such as revisions) rather than things to ponder (such as considerations).
Only (C) makes logical sense and corrects the comparison error.
The best answer is C.
NOTES The words
that, those, and
one are examples of "different copy" pronouns in these sentences:
Some people say that the taste of cilantro is like that of soap.→ "that" = the taste of, but the taste of
soap rather than of cilantro
CR questions on the GRE are similar to those on the GMAT, though there are fewer such questions on the GRE.→ "those" = CR questions, which are mentioned a second time and "belong" to the GMAT
I see that you are enjoying a chocolate truffle; may I have one?→ one = a chocolate truffle, but not the one that you are eating)
When GMAC writers test comparisons, they often use these "copy" pronouns in the correct answer.
When you start to sift through OGs (okay, so you do have a life and whom am I kidding?), you will see quite a few examples of this pattern.
