Something that is "unconventional" is outside the norm and tradition. You can figure this out by considering the component parts of the word: "un-," a negative prefix, and "conventional," which means following typical norms and traditional. Something that is "nontraditional" is different from traditional practices. Again, this word's prefix sheds light on its meaning: "non-," a negative prefix is attached to "traditional," making "nontraditional" mean the opposite of "traditional." Something different from common practice is outside the norm. Therefore, "nontraditional" is the best synonym for "unconventional."

"Copious" means to be excessive or overflowing. "Excessive" means existing in a quantity totaling much more than is needed. Therefore, "excessive" is the best synonym of "copious." A tempting wrong answer choice is "generous" because people who have copious amounts of something may tend to be generous with sharing that thing. However, "generous" is not a synonym of "copious."

"Numerous" means existing in a great quantity, so "copious," which means existing in a large amount, is the correct answer.

"Finite" means limited or fixed in terms of quantity, so "fixed" is the correct answer. "Pertinent" means relevant or appropriate for a specific matter. "Humane" means compassionate, sympathetic, or showing feelings and emotion. "Illicit" means unlawful or illegal. "Livid" means very angry.

The word "myriad" means great in number. The best choice is "countless" because it means too great in number to count or very great in number. Considering the other choices, "shiny" means reflecting a lot of light, "bias" means preference, and "median" means the middle. 

Things that are "redundant" are characterized by unnecessary repetition, so "repetitive" is the answer choice closest in meaning to "redundant" and the correct answer. 

The word "replete" means abundant or full. The best choice is "full" because it is a part of the definition of "replete." 

The word "prolific" means incredibly productive or existing in large quantities. The best choice is "copious" because "copious" also means existing in large quantities. Considering the other choices, "scripted" means planned, "small" means not great in size, and "broken" means reduced to fragments or not able to function as normal.

Something that is “superfluous” is redundant or not needed. To provide further help, “significant” means important; an “impediment” is an obstacle; “loose” means movable, not tight; a “description” is an account or an explanation of something.

“Egregious” means dreadful, terrible, or "appalling." As for the other answer choices, “desirable” means desired or wanted; “lofty” means proud, tall, or high-minded; "considerable" means notable or significant; and "limber" means nimble and flexible.
