"Nonchalant" means disinterestedly casual and unconcerned, so "unconcerned" is the correct answer.

"Vexed" means annoyed, frustrated, or "cross." Although "cursed" is a synonym of "hexed," which sounds like "vexed," it means bewitched to cause harm. The terms "excited" and "lucky" both elude to positive feelings, whereas "vexed" has a negative connotation. "Fleeting" means brief. The best answer choice is "cross."

"Distracted" means not focused or inattentive. "Unfocused" is the correct answer becuase "unfocused" means not focused, as you may be able to figure out from the word's use of the negative prefix "un-," which means not. None of the other answer choices are close in meaning to "distracted": "reasonable" means sensible; "regular" means ordinary; "calm" means tranquil; and "focused" means paying close attention to something or someone. "Focused" is actually an opposite, or antonym, of "distracted."

“Glum” is an adjective that means “looking or feeling dejected; morose,” so we need to pick out an answer choice that means something like “sad.” That means that “glad” cannot be the correct answer, because “glad” means “pleased; delighted,” making it an antonym, not a synonym, of “glum.” “Blue,” however, is an adjective that can mean “melancholy, sad, or depressed,” when referring to a person or mood and being used informally. So, because “blue” is the answer choice closest in meaning to “glum,” “blue” is the correct answer.

Someone who is "inconsiderate" is rude and not considerate of others' feelings, so "rude" is the correct answer. To help you, "composed" means calm, and "dynamic" means active.

“Miserable” means very sad, so the best answer is “unhappy.” The prefix "un-" often negates the meaning of the word that follows it, so it makes sense that “unhappy” means not happy. To provide further help, “lawful” means legal or not against the rules, so “unlawful” means not legal. Finally, “unrestrained” means not restrained or not held back.

Furious means very angry. To provide further help, “unwell” means sick or ill; “quirky” means weird, silly, and unusual; “adorable” means cute; and “loyal” means reliably dedicated to a person or a cause.

"Jealous" means wanting something that someone else has. "Jealous" is most similar in meaning to "envious," a word that means jealous, covetous, or desirous. None of the other answer choices are close in meaning to "jealous": "adequate" means good enough; "mild" means easy or not extreme; and "severe" means intense or extreme.

"Furious" and "enraged" are synonymous; they refer to someone feeling very angry. "Furry" describes an (adorable) texture. "Furtive" describes something that is sneaky or subversive. While the "fur" prefix is similar, these words are completely unrelated.

"Annoyed" and "bothered" are synonymous. They both refer to a feeling of frustration or aggravation caused by something else (a person or a situation, perhaps). The other words do not share these meanings.
