"Commotion" is a noun that means a state that is characterized by confusion and rowdy disturbance. 

"Labyrinth" is a noun that means "a complicated irregular network of passages or paths in which it is difficult to find one's way," so we need to pick out an answer choice that means something like "a complicated network of passages." While "puzzle" may look like a potentially correct answer, "puzzle" as a noun means "a game, toy, or problem designed to test ingenuity or knowledge," not necessarily a "complicated network of passages," so "puzzle" cannot be the correct answer. A "maze," however, is defined either as "a network of paths and hedges designed as a puzzle through which one has to find a way," " a complex network of paths or passages," or "a confusing mass of information," and because the second definition of "maze" is very close to the definition of "labyrinth," "maze" is the correct answer.

“Particle” is a noun that means “a minute portion of matter,” so we need to pick out an answer choice that means something like “a minute portion of matter.” That means that “pile” cannot be the correct answer, because “pile” means “a heap of things laid or lying one on top of another,” and “particle” is specifically only one thing. “Speck,” however, is a noun that can mean “a tiny spot” or “a small particle of a substance,” and because “speck” is the answer choice closest in meaning to “particle,” “speck” is the correct answer.

A "labyrinth" is a difficult maze.
