Synonyms: Adjectives Describing Authenticity, Understanding, and Importance

"Frank" means honest, upfront, or candid, so "candid" is the synonym.

The word "inane" means having no sense. So, "absurd," which means completely senseless, is the best choice. Considering the other choices, "eminent" means distinguished in rank, "smooth" means even on the surface, and "wordy" means talkative.

The word "crucial" refers to something that is necessary to achieve a certain end. For example, if one more loss will eliminate your team from the baseball championship, then winning the next game is crucial. Basically, we are looking for a word that implies great importance. "Vital," which means essential, is the best choice here. "Unimportant" is the opposite of the answer that we want, and "extra" implies that something is present in addition to a certain quantity and unnecessary, not that it is necessary. Finally, "diminutive" means short or unusually small.

Something that is "imperative" is crucial or essential, so "essential" is the correct answer choice. As for the other answer choices, "somber" means _sad and serious; "_abrupt" means sudden ; and "optional" means not necessary.

"Incontrovertible" is an adjective that means "not able to be denied or disputed," so we need to pick out an answer choice that means something like "undeniable." "Unbelievable," while beginning with a negative prefix like both "incontrovertible" ("in-") and "undeniable" ("un-") do, actually means "not able to be believed; unlikely to be true," so it is an antonym of "incontrovertible" and "undeniable."

"Erroneous" is an adjective that means "wrong; incorrect," so we need to pick out an answer choice that means something like "wrong." "Correct," then, cannot be the correct answer, because "correct" is an antonym of "erroneous," not a synonym. "Mistaken," however, is an adjective that means either "wrong in one's opinion or judgment" or especially of a belief, "based on or resulting from a misunderstanding or faulty judgment." Because "mistaken" is the answer choice closest in meaning to "erroneous," "mistaken" is the correct answer.

The word "salient" comes from a Latin word meaning to leap. If someone makes a salient point, it's as if that point is leaping out at you, leading to its meaning of prominent or relevant. Don't be deceived by false cognates, such as "saline" (salty), or "sale" (discounted).
