"Magnanimous" is an adjective that means "very generous or forgiving, especially toward a rival or someone less powerful than oneself." So, neither "stingy" nor "unforgiving" can be the correct answer because each of those words is an antonym of "demure." "Beneficent," an adjective that means "of a person: generous or doing good" or "resulting in good," is the answer choice closest in meaning to "magnanimous," so it is the correct answer.

Because "wanton" means immoral or sexually promiscuous, the best answer choice is "dissolute," which means lax in morals or licentious.

"Headstrong" is an adjective that means "self-willed and obstinate," or "not willing to do what other people want : very stubborn." So, neither "yielding" nor "meek" can be the correct answer because "yielding" and "meek" are both antonyms of "headstrong." "Stubborn" is the closest synonym to "headstrong" amongst the listed answers, so it is the correct answer.

While one might think that “haughty” is related to someone being wealthy, what it generally means is that someone has a “high opinion” of himself or herself. Such a person would judge others as being “beneath” him or her. An adequate description of such a “haughty person” would be “conceited,” which means “being very proud, judging one’s abilities to be great.”

A person who is “lethargic” lacks energy and does not care much for undertaking any activities. Among the options provided, “inert” is closest to this. In chemistry, you may have spoken of “inert” compounds or elements—those that do not undergo chemical reactions. “Inert” is derived from the combination of “in-,” here used as meaning “not” (as in “indivisible”), and the word for “skill” or “art” in Latin. To be “inert” is therefore to lack skills, arts, or (at least) activities.

A prude is someone who is easily offended about sexual morality, often being judgmental of others. By extension, the term can generally mean “judgmental.” When someone is “censorious,” he or she is very critical—like one who censors the actions of others.

The word “parochial” is related to statutes in the law of the Catholic Church defining the geographic boundaries in which a parish church exists. The word became extended in meaning to signify the character of someone that someone never leaves that small area. If someone becomes limited in travel, that person will likely also be limited in his or her exposure to new ideas. For that reason, the word “parochial” has taken on the additional meaning of “narrow or limited in outlook.” Illiberal can mean “uncultured” in the sense of being “not free-thinking or broad minded.”

The adjective “vitriolic” describes a kind of speech that is critical not in there merely “evaluative” sense but instead in a nasty and spiteful manner. An example use of the word would be, “She did not merely speak mild words to her adversary but instead, in great anger, shouted vitriolic condemnations against him.”

A thrifty person is very careful not to waste resources. While it might be tempting to assume that such a person is greedy or avaricious, the word only expresses the fact that he or she “pinches pennies,” that is, is very careful with any outlays. Note that someone can be “thrifty” with any resources, though the term is most often used to describe care with regard to money. The word “frugal” is the only option that expresses this notion of thrift.

The word “frugal” is related to base words in Latin for “fruit.” It means “being economical” or careful with resources. When someone is “thrifty,” he or she is careful in spending money. A “thrift store” is generally a second-hand store meant to allow people to save money on products that can be purchased at a lower-than-normal price because they are second hand.
