KAPLAN Official ExplanationRead the Original Sentence Carefully, Looking for Errors:
In the original sentence, "there" must refer to Liberia, but notice that Liberia itself is not directly mentioned in the sentence, only the Liberian Civil War. The correct answer will remove this unclear reference. Eliminate (A).
Scan and Group the Answer Choices:
There's no clear way to group the remaining choices, so evaluate them one by one.
Eliminate Choices Until Only One Remains:
(B) is wrong because "where" clauses, unless they are used as adverbs, must refer directly to an actual place. In (B), there is no place for the "where" clause to modify. Additionally, the passive construction "can have these measures specifically applied to it" is wordy and cumbersome.
(C) replaces the concise "strict policies" with the unnecessarily wordier "policies that are strict." Furthermore, the pronoun "their" has no clear antecedent.
(D) avoids the vagueness of the other choices by using the possessive of 'Liberia' to state clearly where the volatile situation is occurring. It's likely correct, but check (E) to be sure.
(E) also uses the wordy "policies that are strict," and repeats the unclear use of "there".
(D) is correct.
TAKEAWAY: "There" needs to refer to a specific place mentioned in the sentence.
