The prefix "extro-" means outside, so it makes sense that “extroverted” means outgoing and gregarious. As for the other answer choices, "reserved" means shy and inhibited or unavailable because something is being kept for someone specific; “calculating” means cunning, ruthless, crafty, and shrewd; “radical” means holding or supporting extreme reform; and "precocious" means developing and learning at an advanced rate.

The prefix "de-" can mean away or remove, and the rest of the word, "-funct," is related to the Latin term meaning work (think of the English word "function"). It thus makes sense that "defunct" means no longer working or "inoperative." As for the other answer choices, "suppressed” means held down, repressed, or crushed; “disorderly” means out of control; “hampered” means impeded, obstructed, or slowed down; and "considerate" means thinking of other people's feelings when making decisions or deciding how to act.

The word “constitute” is comprised of two parts that you likely know. The prefix “con-” means “with” and is found in “concur” as well as in the related “cum-” form in “cumulative” and the “com-” form in “commune.” The “-stitute” comes from the Latin for “to stand” or “to set up.” The United States “Constitution” is so named because it “sets up” the whole nation out of the parts from which it is “constituted.” The word can also mean “to be a part out of a whole,” as in, “The small group constituted a minority in the larger society.”

The word “convivial” literally means “living with.” It is derived from the prefix “con-”, meaning “with” and the base “-vivial,” which is related to a cluster of words signifying life or living such as “vivacious,” “survive,” and “revive.” When someone is “convivial,” he or she is friendly or sociable. It is this latter sense that is found among the possible answers.

The word “progressive” is related to words like “regress” and “digression.” It is comprised of two roots, both of which are likely familiar. The prefix “pro-” here means “forward.” The “-gress” comes from the Latin word for “to step.” The words “grade” and “gradual” both come from this same base, as do the aforementioned words. The word “progress” means “a step forward” in the sense of advancing some activity or cause. The word “progressive” has many uses, though they all are related to this sense of “advancing.” A “progressive” idea is often one that looks to advance or make better the world. It often comes with the additional sense of being “enlightened” (sometimes implying, unfairly, that those who hesitate to make such changes are not as high-minded). Among the options provided, “developing” most closely fits the sense of “advancing.”

The word “atheist” means “one who does not believe in the existence of any god. The “a-” prefix here is privative, making the word to mean the opposite of the base “theist.”

The base itself means “one believing in God.” It is found in other words like “theology” (the study of God or gods) and “pantheism” (the belief that the world and God are identical). Likewise, the “th” becomes “d” in some contexts like “deity” and “deism.” Among the options given, the best is “nonbeliever.” Do not be tricked by the other options that are at most accidentally related to the word “atheist.”

"Antecedent" is a noun that means "a thing or event that existed before or logically precedes another," so we need to pick out another answer choice that means something like "forerunner." "Predicate" may look like a potentially correct answer because both it and "antecedent" have meanings specific to grammar. ("Antecedent" can also mean "a word, phrase, clause, or sentence to which another word (especially following a relative pronoun) refers.") However, "predicate" does not mean the same thing as "antecedent," so it cannot be the correct answer. "Precursor," a noun which means "a person or thing that comes before another of the same kind; a forerunner," is the answer choice that is closest in meaning to "antecedent," so "precursor" is the correct answer.

Often, one speaks of a “eulogy” being delivered at a funeral, but such speeches are not necessarily limited to those occasions. The word is comprise of the prefix “eu-” and “-logy.” The former means “good.” It is found in the word “euphony,” meaning “good sounding.” The “-logy” portion of “eulogy” means “words” as found in the English word “logic.” For these reasons, “eulogy” generally means a speech given in praise of someone. A panegyric is likewise such a positive speech.

The “-mission” portion of “intermission” is related to Latin root words for “to send.” The word “transmit” literally means “to send across (from one area to another).” The prefix “inter-” means “between.” “Interscholastic” sports are sports between two schools. An intermission is a period of time that is placed “between” two things, for instance, between two acts in a play. The word “interval,” though somewhat more vague than this sense, is the best option among those given.

The word “refuge” is derived from the prefix “re-”, here implying the sense of “back” and the base “-fuge.” The “-fuge” base is related to English words like “fugitive” and “refugee.” It is derived from the Latin for “to flee.” “Refuge” thus means “to flee back(ward).” A place that is a refuge is one to which someone flees for protection. For example, one could say, “The child fled to its mother’s arms as a refuge from its fear.” Of course, the word could be used to refer to a building, location, or anything else of that sort.
