A "mendicant" is a vagabond or a beggar. An "iconoclast" is someone who goes against established traditions or beliefs. A "harbinger" is an omen or portent. A "contaminant" is an impurity or pollutant. A "proclivity" is a tendency or a habit.

"Stevedore" and "dockworker" are both synonyms. "Drivel" means foolish talk or babble. "Virtuoso" means a person who is an expert. "Dotard" means a fogy or dull person. "Instigator" means troublemaker or agitator. 

"Ward" is a noun that can mean "a separate room in a hospital, typically one allocated to a particular type of patient," "an administrative division of a city or borough that typically elects and is represented by a councilor or councilors," or "a person, usually a minor, under the care and control of a guardian appointed by their parents or a court." So, we need to pick out an answer choice that means something like "a separate room in a hospital," "an administrative division of a city," or "a person under the care of a guardian." "Protector," then, cannot be the correct answer, because "protector" means the opposite of the third definition of "ward." "Dependent," however, when used as a noun, means "a person who relies on another, especially a family member, for financial support," and because "dependent" is the answer choice closest in meaning to "ward," "dependent" is the correct answer.

"Coterie" means clique or small group of friends, so "clique" is the correct answer. None of the other answer choices is close in meaning to "coterie": "extraction" means the act of removing something or the act of taking something out of something else; an "omnivore" is an organism that consumes meat and vegetables; "insurgency" is an organized rebellion, usually against an established government; and "malfunction" means not function properly or break down.

Do not confuse the word “rabble” with “ramble.” The latter means either “to wander” or “to speak in a confused, unending manner.” A “rabble” is a disorganized mob, sometimes implying that such people are the “low class rabble.” The best option among those provided would be “mob.”

"Savant" and "intellectual" both mean an academic or highly intelligent person. "Amateur" means beginner or learner. "Misogynist" means someone who hates women. "Iconoclast" is someone who breaks from established norms or traditions. "Enigma" is a puzzle or riddle.

The word “adversary” literally comes from the roots “to turn toward.” The word “reverse” has a similar root in it, here meaning to turn back. (The “re-” prefix indicates the “back” portion of the meaning.) Someone’s adversary is not necessarily a fighter in the literal sense, though that person is “turned toward” another person or, in another way, turned against that person. While two people in a duel are adversaries, it is likewise the case that two disputing scholars could be called the same.

"Sycophant" means lackey, croney, or minion. "Analogue" means parallel or matching. "Implication" means association or suggestion. "Enigma" means riddle or puzzle. "Misanthrope" means someone who hates others.

The noun “mechanic” merely means one who specializes in maintaining and fixing things that are mechanical, that is, machinery and technology. Options like “technical” and “fabricated” do not work, as they are adjectives. “Laborer” is not as close as “technician,” which best captures the sense of working on technological (hence mechanical) things.

You might know the word “mendacious,” which means “lying.” The word “mendicant” does not mean this but instead means “beggar.” The word is often used to describe certain religious order in the Roman Catholic church, which arose in the Middle Ages, like the Franciscans and Dominicans who originally made their living begging while they preached. The word can be used more broadly, but it also is important to know this historical usage, as it comprises a significant factor in late pre-modern history.
