GRE Vocabulary Builder

Answer: Choice (D) is correct.

In the first half of the analogy, peremptory means authoritative or absolute, the opposite of indecisive, so look for the answer choice that contains antonyms. In choice (A), something that is cryptic is mysterious and like an enigma or puzzle (therefore, enigmatic), so eliminate choice (A). In choice (B), daunting and intimidating both mean something that is frighteningly overwhelming, so eliminate that choice. In choice (C), something that is emaciated is gaunt and thin, so eliminate that choice. In choice (D), something that is extant is currently in existence, not extinct. Choice (D) is the only choice with antonyms, so it is the correct choice.
