costsOFFICIAL EXPLANATION
Whenever you see certain relative pronouns (who, which, where, whose) in a sentence correction problem, you should hone it on those as an initial decision point.
Here you see the obvious choice between “which” and “as” to start each answer.
The broad rule for non-restrictive relative pronouns (those used with a comma and giving extra information about what they are beside) is that they must be beside (or very close to) a noun that they can logically modify.
For (A), (B), and (C), it is not the AP exams that allow students to skip courses and save tuition – rather it is a good performance on those exams! =Given this you can eliminate (A), (B), and (C).
(D) and (E) properly use the conjunction “
as” to link together a separate clause that explains what high scores will do for students.
(E) contains two errors seen in some of the other answers: there is a reference error with the pronoun “
them” and the “
costs” after tuition is unnecessary and redundant.
The correct answer is (D).
