"Inferior" means of lesser quality or substandard. "Superior" means of greater quality, so it is an antonym, not a synonym, of "inferior." The other answers are not close in meaning to "inferior": "loyal" means obedient or consistently supporting something or someone; "promising" means potentially yielding good results; and "competent" means having the necessary skills to accomplish something.

Akin means similar or comparable. For clarification, unique means distinct and original; vie means to compete or struggle.

"Conventional" means well-established, normal, socially accepted, or traditional. For clarification, "unique" means distinct; "cerebral" means intelligent; "tolerant" means patient, and "intolerant" is an antonym of patient.

"Akin" means similar or related; the word was originally formed from a contraction of the phrase "of kin," in which "kin" means family. So, "related" is the correct answer. None of the other answer choices are close in meaning to "akin": "unclear" is a combination of the negative prefix "un-," which means not, and clear, so you might be able to infer that it means not clear, or in other words, shrouded or hard to see or understand; "authentic" means genuine or real; "frank" means honest and straight to the point; and "irritated" means annoyed or upset.

"Estranged" means alienated. The best answer is "distant" because when you feel estranged, you feel distant from others.

Words you may not know:

• "Exacerbate" means to make worse or to irritate.

"Awry" can act as an adjective or an adverb and means "away from the appropriate, planned, or expected course," so we need to pick out a word that means something like "away from the expected course." While "wiry" sounds similar to "awry," "wiry" means "resembling wire in form and texture." Since "wiry" does not mean the same thing as "awry," it cannot be the correct answer. "Amiss," however, means "not quite right; inappropriate or out of place" as an adjective and "wrongly or inappropriately" as an adverb. Because "amiss" is the answer choice closest in meaning to "awry," it is the correct answer.

Something that is "diminutive" is small, miniature.

"Abominable" means universally hated. If you "detest" something, you hate it. The key here is the strength of the word, an "abominable" thing is awful, not merely bad, or "questionable."

"Mundane" is an adjective that means "dull," without excitement, or refers to the earthly world instead of a spiritual world.

"Metaphysical" means related to the philosophy that deals with abstract concepts (being, origin of the universe) but is not grounded in scientific research.

"Feeble" is an adjective that means "weak," or without strength of character.

"Infantile" could also be related, as infants typically lack physical strength, but "infantile" simply means childish. "Gleeful" means very joyful. "Cumbersome" means inconvenient, or difficult to carry or use because of size.
