To be "bountiful" is to have plenty of something or have an "abundance" of it. "Restricted" is the antonym of abundance and indicates having a small amount. "Superb" means excellent in quality; "sufficient" means having enough; and "sparse" means having a small quantity.

The word "typical" generally means matching the general features of a given type (of thing). A "typical coffee mug" is your standard mug, having a roundish body and a handle. It "fits the mold," so to speak. Therefore, the word "typical" can also mean average or normal. A "typical mug" is likewise normal—as coffee mugs go at least. Therefore, the best answer is "average," which alone indicates such normalcy.

“Capacious” means roomy, able to hold a large amount of something. This is most similar in meaning to “commodious,” which means roomy and spacious. To provide further help, “tenacious” means stubborn, resolute; “antithesis” means evidence against the argument; “loquacious” means talkative; “homogenous” means consisting of similar or identical, things. 

"Bizarre" means strange, unusual, or odd.

“Sundry” is an adjective that means “of various kinds; several,” so we need to pick out an answer choice that means something like “of various kinds.” That means that “uniform” cannot be the correct answer, because “uniform” can mean “of a similar form to another,” making it an antonym, not a synonym, of “sundry.” “Diverse,” however, is an adjective that means “showing a lot of variety,” and because “diverse” is the answer choice closest in meaning to “sundry,” “diverse” is the correct answer.

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.
