As for the other answer choices, "frequent" means happening many times or happening often, "courageous" means bold or brave, and "swift" means agile or quick.

"Unruly" means disorderly or rowdy, so "rowdy" is the correct answer. None of the other answer choices are close in meaning to "unruly": "sympathetic" means showing sympathy or compassion; "toxic" means poisonous; "modern" means new and contemporary; and "contagious" means spreading easily from person to person and usually refers to illnesses or diseases.

“Faithful” means devoted or loyal, so "devoted" is the correct answer. To provide further help, “disloyal” means not loyal, “mendacity” is another term for dishonesty or lying, “forcible” means aggressive, and “defamatory” means insulting and slanderous and is used to refer to information that is rude and probably not true.

"Passionate" is defined as showing or caused by strong feelings or strong beliefs. The best answer choice is "emotional," since those who are "emotional" display intense feelings and are often described as being "passionate."

A "shrewd" individual is perceptive; he or she is quick-witted and skilled at using thinking to solve problems. In other words, a shrewd person is "clever." "Foolish" is clearly an incorrect choice; "bland" means tasteless or boring, and "exciting" refers to an event that causes people to become eager or excited.

A "captivating" person grabs the interest of others and keeps it. When describing someone like this, one might use the phrase "can't tear my eyes away," meaning that it is very difficult to ignore that person. Here, the answer choice with the most similar meaning is "fascinating." "Drab" usually describes something that is dull or boring; "pointless" means meaningless, and "quick" is another word for fast.

The adjective "jocular" describes someone who tends to make jokes or act lighthearted. "Humorous," another term for funny, is the proper choice. You likely already know the meanings of "tired" and "smart," and therefore know that neither word refers to a playful or joking manner. Finally, "exasperated" is a good word to know, though not the correct answer. You've probably felt "exasperated" when you've been annoyed by an irritating situation that has gone on for too long.

"Diligent" means putting one's whole effort into carefully doing something. "Attentive," meaning demonstrating careful thought or observation, is the best match.

"Flippant" means lacking proper respect. "Sassy" is the best match because it means cheeky or impertinent.

Think of "unruly" as an adjective meaning not following rules, difficult to control, or rebellious. "Obedient" and "faithful" are antonyms of "unruly" and "rebellious." "Meager" means very small or too small in amount.
