In general, the word "levity" is related to humor or amusement. Specifically, it refers to joking or carefree happiness that interrupts a more serious mood. "Lighthearted" basically means happy in a way that lacks seriousness, so "lightheartedness" is the correct synonym here. Let's check the other three answer choices. Although it rhymes, "brevity" has nothing to do with levity; it denotes conciseness of language or (more generally) a short duration. "Solemnity" is synonymous with seriousness, so it is an antonym of our original term, and "natal" is an adjective that means associated with birth or newborn babies.

The "onset" of something is its start or its beginning, so "start" is the correct answer. None of the other answer choices are close in meaning to "onset": a "sample" is a small amount of something having the characteristics of larger amounts or the whole thing; "discovery" is the act of finding out something new; a "riot" is a violent demonstration or protest; and a "setting" can mean the time period and location in which a story takes place.

"Intent" is a word that when used as a noun means "intention or purpose," and when used as a verb means "resolved or determined to do (something)," "attentive occupied with," or, especially of a look, "showing earnest and eager intention." Because all of the answer choices are nouns, we will need to consider "intent" as a noun and pick out an answer choice that means something like "intention" or "purpose." So, while "content" and "intent" may both contain the syllable "tent," "content" when used as a noun means either "a state of satisfaction" or "the substance or material dealt with in a speech or literary work, as distinct from its form or style." So, "content" does not mean the same thing as "intent" and cannot be the correct answer. "Goal," however, is a noun that can mean "the object of a person's ambition or effort; an aim or desired result," and because "goal" is the answer choice closest in meaning to "intent," "goal" is the correct answer.

Discord means disagreement or conflict. To further help you, harmony, accord, and concord are all synonyms and mean agreement.

The word "corroboration" means proof that confirms a given theory or statement is correct; therefore, "confirmation" is the word that most closely matches its definition, as "confirmation" can mean information that confirms something. "Contrition" means guilt, penitence, or regret, so it is is unrelated to the definition of "corroboration." "Idealism," which means the characteristic of chasing unrealistic dreams of perfection, is also unrelated. A "contradiction" occurs when the difference between two things means that both cannot be true. This is almost the opposite of "corroboration."

"Luck" is a noun that means "success or failure apparently brought by chance rather than through one's own actions" or "something regarded as bringing about or portending good or bad things." So, we need to pick out an answer choice that is a noun and means something like "chance." "Predictability" might sound like the correct answer, but if something is predictable, it is not likely to be occurring by chance, so "predictability" cannot be the correct answer. "Fortune," however, is a noun that can mean "chance or luck as an external, arbitrary force affecting human affairs" or "luck, especially good luck," and because it is the answer choice closest in meaning to "luck," "fortune" is the correct answer.

"Plight" means a dangerous situation or a predicament, so "difficulty," which can be used to mean a difficult situation, is the correct answer. To help you, a "beverage" is a drink, and a "banquet" is a feast.

"Mischief" is a noun that means "playful misbehavior or troublemaking, especially in children," or "harm or trouble caused by someone or something." So, while "mistake" may look like a good answer choice because both "mischief" and "mistake" begin with the prefix "mis-", which means "wrongly," "mistake" does not mean the same thing as "mischief," so "mistake" cannot be the correct answer. "Trouble" is the answer choice closest in meaning to "mischief," so "trouble" is the correct answer.

An "aspect" is a feature or a part, so "feature" is the correct answer. A "document" is a piece of paper with information written on it, usually in words. An "option" is a choice or a possible selection. "Leisure" means free time or time off. An "emergency" is a sudden event requiring immediate attention.

A “skirmish” is a small fight or battle. A "wound" is a physical injury, so while you may receive a wound in a skermish, "wound" does not mean the same thing as "skirmish."
