“Mundane” is an adjective that means “lacking interest or excitement; dull” or “of this earthly world rather than a heavenly or spiritual one,” while “humdrum” is a word that when used as an adjective means “lacking excitement or variety; dull; monotonous.” So, “mundane” and “humdrum” are synonyms, and we need to pick out an answer choice that also consists of a pair of synonyms. While “wizened is to young” and “unfamiliar is to alien” might both look like potentially correct answers, “wizened” is an adjective that means “shriveled or wrinkled with age,” so it is an antonym, not a synonym, of “young,” and “wizened is to young” cannot be the correct answer. “Unfamiliar” is an adjective that means “not known or recognized,” and “alien” is a word that when used as an adjective can mean “unfamiliar and disturbing or distasteful.” So, because “unfamiliar” is a synonym of “alien” just as “mundane” is a synonym of “humdrum,” “unfamiliar is to alien” is the correct answer.

“Vessel” is a noun that can mean “a ship or large boat” or “a hollow container,” or chiefly in or alluding to biblical use, “a person having a particular quality.” So, “vessel” and “ship” are synonyms, and we need to pick out an answer choice that also consists of a pair of synonyms. While “report is to account” and “fascination is to ennui” might each look like a potentially correct answer, “ennui” means “a feeling of dissatisfaction arising from a lack of excitement,” making it an antonym, not a synonym, of “fascination.” So, “fascination is to ennui” cannot be the correct answer. “Report,” however, when used as a noun, can mean “an account given of a particular matter, especially in the form of an official document, after thorough investigation or consideration by an appointed person or body.” So, because “report” and “account” are synonyms, just as “vessel” and “ship” are synonyms, “report is to account” is the correct answer.

A pterodactyl is a kind of dinosaur, so we need to pick out an answer choice that consists of a kind of dessert. While both "water" and "brownie" may look like potentially correct answer choices because each can be consumed by humans, "brownie" is the correct answer, because while "water" is not a kind of a desert, "brownie" is.

A group of wolves is called a pack. Similarly, a group of geese is called a gaggle.

None of the other analogies have this specific relationship.

Groups of children are not called a school, although groups of children do go to school.

Wolf and dog are related, but the analogy does not fit the relationship of single animal to group of that animal.

Groups of pigs do live on farms, but the order of the words is incorrect: a group of farms is not called a pig.

A group of reptiles is not called a herd; a herd typically refers to a group of hoofed animals.

A xylophone is an example of an instrument, so we need to pick out an answer choice that consists of two nouns, where the first is an example of the second. While “pear is to fruit” and “game is to chess” might each look like a potentially correct answer, “game” is not an example of a “chess,” so “game is to chess” cannot be the correct answer. A pear is an example of a fruit, however, just as a xylophone is an example of an instrument, so “pear is to fruit” is the correct answer.

If something is “undulating,” it is wavy. If someone is “fatigued,” they are tired. To clarify, “starved” means very hungry.

A "sleuth" is another name for a "detective." So, an action likely to be undertaken by a "sleuth" is to "investigate." To solve this analogy you need to determine which of these is an action likely to be undertaken by a "wretch." Well, a "wretch" is a miserable, pitiable person who is suffering. So, the correct answer is "bemoan," which means express sorrow or frustration with. Additionally, "allude" means hint at, suggest; "disorient" means make feel lost or confused; "atrophy" means weaken over time due to lack of use.

A carpenter uses a hammerto build wooden objects, so we need to find a similar relationship in the analogies. A "metalworker" uses a "welding torch" to build metal objects. "Metalworker" and "welding torch" have the same relationship as carpenter and hammer.

A captain uses a boat, but the boat is not simply a tool for the captain, it is the captain's home.

Birds hatch from eggs, there is no user or tool in this analogy.

Chefs make food, but food is not the tool of the chef.

The policeman is not the tool of the baton, but vice versa. Analogies must match conceptually, so if you have a user paired with a tool, you need to find an answer that also has a user and a tool.

"Commute" is a verb that means to go to "work," to journey to or from "work." So, which of these places do you go to if you are "matriculating?" The correct answer is that "matriculate" means go to college, enroll at college.

The correct answer is "paintbrush is to artist."

This analogy explores the relationship of a tool and the user of the tool. Clippers are used by a barber to perform the task of cutting hair; likewise, a paintbrush is used by an artist to paint.
