SAT Vocab Builder

Answer: Choice (D) is correct.

A curmudgeon is a person who is cantankerous, or bad-tempered. Therefore, look for an answer choice in which the second term describes the first term. In choice (A), a churl is rude, not agreeable. In choice (B), a demagogue is a person who passionately appeals to the emotions of others, not dispassionate. A pundit is an authority on a subject, and therefore not uninformed, so eliminate choice (C). In choice (D), a boor is someone who is rude and offensive.
