"Delusion" is a noun that means "a belief that is firmly maintained despite being contradicted by accepted as reality, typically a symptom of mental disorder," or "the action of deluding someone or the state of being deluded." So, we need to pick out a noun that means something like "misinterpretation." "Actuality," then, cannot be the correct answer, because "actuality" means "actual existence, typically as contrasted with what was intended, expected, or believed," making it an antonym, not a synonym, of "delusion." "Fallacy," however, is a noun that can mean "a mistaken belief, especially one based on unsound argument," and because "fallacy" is the answer choice closest in meaning to "delusion," "fallacy" is the correct answer.

“Zeal” is a noun that means “great energy or enthusiasm in pursuit of a cause or an objective,” so we need to pick out an answer choice that means something like “great energy or enthusiasm.” That means that “ennui” cannot be the correct answer, because “ennui” is a noun that means “a feeling of listlessness and dissatisfaction arising from a lack of occupation or excitement,” making it an antonym, not a synonym, of “zeal.” “Fervor,” however, is a noun that means “intense and passionate feeling,” and because “fervor” is the answer choice closest in meaning to “zeal,” “fervor” is the correct answer.

“Reprieve” is a word that can be used as a verb or a noun, but because all of the answer choices are nouns, we need to consider “reprieve” as a noun. When used as a noun, “reprieve” can mean “an official order that delays the punishment of a prisoner who is sentenced to death,” “a delay that keeps something bad from happening,” or “a period of relief from pain or trouble.” So, we need to pick out an answer choice that means something like “an official order that delays a prisoner’s execution,” “a delay that keeps something bad from happening,” or “a period of relief.” That means that “agony” cannot be the correct answer, because “agony” means “extreme physical or mental suffering” or “the final stages of a difficult or painful death,” making it an antonym, not a synonym, of “reprieve.” “Respite,” however, is a noun that means “a short period of rest or relief from something difficult or unpleasant,” and because “respite” is the answer choice closest in meaning to “reprieve,” “respite” is the correct answer.

“Nuisance” is a noun that means “a person, thing, or circumstance causing inconvenience or annoyance,” so we need to pick out an answer choice that means something like “something or someone causing inconvenience.” That means that “comfort” cannot be the correct answer, because “comfort,” when used as a noun, can mean “a person or thing that gives consolation,” making it an antonym, not a synonym, of “nuisance.” “Annoyance,” however, is a noun that can mean “a thing that annoys someone; a nuisance,” and because “annoyance” is the answer choice closest in meaning to “nuisance,” “annoyance” is the correct answer.

“Sabotage” is a word that can be used as a verb or a noun, but because all of the potential answer choices are verbs, we will need to consider it as a noun. When “sabotage” is used as a verb, it means “deliberately destroy, damage, or obstruct (something), especially for political or military advantage,” so we need to pick out an answer choice that means something like “deliberately destroy.” That means that “renovate” cannot be the correct answer, because “renovate” is a verb that means “restore (something old, especially a building) to a good state of repair,” making it an antonym, not a synonym, of “sabotage.” “Wreck,” however, is a word that when used as a verb, can mean “destroy or severely damage (a structure or vehicle),” and because “wreck” is the answer choice closest in meaning to “sabotage,” “wreck” is the correct answer.

“Assembly” is a noun that can mean “a group of people gathered together in one place for a common purpose,” so we need to pick out an answer choice that means something like “a group of people gathered together with a common goal.” That means that “individual” cannot be the correct answer, because “individual,” when used as a noun, means “a single human being as distinct from a group, class, or family,” making it an antonym, not a synonym, of “assembly.” “Meeting,” however, is a noun that means “an assembly of people, especially the members of a society or committee, for discussion or entertainment,” and because “meeting” is the answer choice closest in meaning to “assembly,” “meeting” is the correct answer.
