The prefix "brev-" comes from "brief" and means short or quick. “Brevity” means shortness, briefness. To provide further help, “pompous” means proud and arrogant; “preeminent” means highly regarded, in charge, most distinguished; “sanctimonious” and “pious” are synonyms of one another and both mean self-righteous. 

"Tirade" is a noun that means "a long, angry speech of criticism or accusation," so we need to pick out an answer choice that means something like " a long, angry speech." While "conversation" has to do with speech just like "tirade" does, "conversation" means "an informal talk involving two people or a small group of people : the act of talking in an informal way," so it cannot be the correct answer because "conversation" does not include any angry connotations like "diatribe" does, and it's a conversation in which two people participate instead of a one-sided speech like "tirade" describes. "Rant," however, when used as a noun, means "a spell of ranting; a tirade," and when used as a verb, it means "speak or shout at length in a wild, impassioned way." Because "rant" is the answer choice closest in meaning to "tirade," "rant" is the correct answer.

"Amity" means peace or friendship. The answer choice closest in meaning to "amity" is "fellowship" since it indicates camraderie or companionship. As for the other choices, "allure" is attraction; "crudeness" is roughness; equality refers to the concept of giving everyone equal treatment; and obedience is the quality of complying with requests and demands.

Since "income" is a noun that means money received on a regular basis for work, we're looking for another noun that also means earnings. "Debt" may sound like a potential answer because it is a noun that has to do with finances and often discussed along with "income," but "debt" refers to money that is owed to someone else, so it is actually an antonym of income and not the correct answer. "Salary," on the other hand, means a fixed regular payment made by an employer to an employee, so it is the closest in meaning to "income" and the correct answer.

"Condolence" is a noun that is usually used in its plural form and means "an expression of sympathy, especially on the occasion of a death." So, we need to pick out an answer that means something like "an expression or sympathy." "Indifference," then, cannot be the correct answer because "indifference" is a noun that can mean "lack of interest, concern, or sympathy," making it an antonym, not a synonym, of "condolence." "Compassion," however, is a noun that can mean "sympathetic pity and concern for the sufferings or misfortunes of others," and because "compassion" is the answer choice closest in meaning to "condolence," "compassion" is the correct answer.

"Intuition" is defined as the power of knowing something immediately without conscious reasoning. The best match for this is "instict," which means innate knowledge.

An "adjunct" is something that is added on to something that already exists. The best choice is "addition" because something that is an "adjunct" is an "addition" to something else. Considering the other choices, a "division" is a separation, "junk" is something of little value or things of little value, and a "juncture" is a point at which two things are joined.

A "proposal" is also known as a suggestion, so "suggestion" is the correct answer.

"Incentive" is motivation or the reason behind doing something, so "motivation" is the correct answer. To help you, "garrulous" means talkative, "barrage" means overwhelm with a repeated attack, and "insipid" means dull or banal.

A "conundrum" is something that is very difficult to understand. The best choice is "enigma," which means a person or thing that is very difficult to understand. Considering the other choices, "instrument" means an object or tool used to perform a task, often specifically to perform music, "cusp" means edge, and "enlightenment" means the state of having gained knowledge.
