To feel "exasperated" means to feel very frustrated. For clarification, "magnificent" means glorious and wonderful; "munificent" means generous; "gregarious" means outgoing and sociable.

Someone who is "exuberant" is very cheerful, so "cheerful" is the correct answer. For clarification, "feral" means wild, "parsimonious" means not generous, "languid" means lazy and lethargic or slow when referring to movement(s), and "kinetic" means having to do with movement. 

"Livid" means furious, irate or very angry, so "very angry" is the correct answer.

"Elated" means very happy, so "jubilant," an adjective that means triumphant or gleeful, is the correct answer. "Depressed" is an antonym of "elated" and "jubilant"; it means sad and gloomy. None of the other answer choices have meanings related to that of "elated": "tasty" means delicious or flavorful; "frigid" means very cold; and "friendly" means amiable.

"Sheepish" means embarrassed or uncomfortable, so "embarassed" is the correct answer. None of the other answer choices are close in meaning to "sheepish": "swift" means rapid or quick; "energetic" means lively or having or showing a lot of energy; "sympathetic" means compassionate or understanding; and "flexible" means bendable.

"Miserable" means sad or unhappy, so "unhappy" is the correct answer. "Joyful" is an antonym of "miserable"; it means very happy or cheerful. "Lethal" means dangerous and possibly causing death. "Sturdy" means strong or robust. "Grimy" means filthy or dirty.

"Envious" most nearly means jealous, as in "Admiring the movie star's gorgeous looks, Lori felt slightly envious of her beauty."

"Sanguine" most nearly means cheery when faced with difficulty, as in "Despite the fact that his opponent had beaten him before, Gary remained sanguine about his chances of winning the race."

"Aghast" is an adjective that means stunned or horrified, so we need to find another adjective that means something that has to do with feeling shock or fear. While "ghastly" sounds like "aghast," it is an adjective that means terrible or shocking. Since "ghastly" does not mean the same thing as "aghast" ("shocking" doesn't mean the same thing as "shocked"), it can't be the right answer. "Alarmed," on the other hand, means frightened, and since it is the answer choice closest in meaning to "aghast," it is the correct answer.

"Contrite" is an adjective that means "feeling or expressing remorse or penitence; affected by guilt," so we need to pick out another adjective that means something like "feeling guilty." While "pennant" and "penitent" sound quite similar to one another, "pennant" is a noun meaning "a long, thin, pointed flag," while "penitent" is an adjective meaning "feeling or showing sorrow and regret for having done wrong; repentant." Because "penitent" is the answer choice closest in meaning to "contrite," "penitent" is the correct answer.
