A "paddock" is an enclosure for certain animals, like a "horse." So, to solve this analogy you need to determine which of these is kept in a "penitentiary." Well, a "penitentiary" is a jail for people who have committed serious crimes. So, the correct answer is "felon," which means convicted criminal. Additionally, a "bachelor" is an unmarried man; a "widow" is a woman whose husband has died; an "infant" is a baby.

One would expect to find a knight in a castle, so we need to pick out an answer choice that describes where one would expect to find a surgeon. Because one would expect to find a surgeon in a hospital, "hospital" is the correct answer.

“Timber” is a noun that can mean “wood prepared for use in building and carpentry,” but when used as an exclamation, it can also mean “used to warn that a tree is about to fall after being cut.” So, we need to pick out an answer choice that either indicates something that is made from golf balls, or a word that is used to warn someone about a golf ball. All of the answer choices are words that someone might exclaim in different contexts, but “fore” is specifically a word that when used as an exclamation means “a warning to people in the path of a golf ball.” So, because one would logically shout “fore” to warn people in the path of a golf ball just as someone would logically shout “timber” to warn people near a falling tree, “fore” is the correct answer.

A "submarine" goes under the water, so to solve this analogy you have to determine which answer choice a subway goes under. The answer, of course, is that a subway goes underground.

"Sail" is an action undertaken on the ocean, so to solve this analogy, you have to determine where it is that someone is likely to drive. So, the answer is “highway.”

A bullfrog would likely live in a pond, so we need to pick out an answer choice in which the second word is an animal and the first word that animal’s likely habitat. While “ocean is to whale” and “glacier is to toucan” might each look like a potentially correct answer, “toucan” is defined as a colorful tropical bird notable for its large bill, and because it is “tropical,” it lives in rain forests and would not likely live on a glacier. Whales, however, live in the ocean, just as bullfrogs can live in ponds, so “ocean is to whale” is the correct answer.

Since an exhibit is part of a museum, we need to find another pair of words in which the first word represents something that is a constituent part of the second. While "book is to cover" may look like a good answer, the words appear in the wrong order, so it can't be the right answer. (A book is not part of a cover, a cover is part of a book). "Page is to book," on the other hand, does have its words in the correct order, and since a page is a constituent part of a book, "page is to book" is the correct answer.

Since one wears glasses on one's face, we need to pick out a noun that describes where on one's body one wears a shirt. While most shirts cover one's shoulders and waist, they cover more than just those parts of the body. "Torso" is the best answer, because it most accurately represents the entire area that a shirt covers.

“Ill” is an adjective that can mean “not in full health; sick,” so if one is feeling ill, one might logically go to a hospital. So, we need to pick out an answer choice that consists of an adjective and a noun that describes a place one might logically go if one were feeling how the adjective conveys. While “exercise is to gym” and “hungry is to restaurant” might each look like a potentially correct answer, “exercise” is not an adjective, but a verb, so “exercise is to gym” cannot be the correct answer. If one is feeling hungry, however, one might logically go to a restaurant, just as if one were feeling ill, one might logically go to a hospital, so “hungry is to restaurant” is the correct answer.

Since nurses work at hospitals, we need to pick out a noun that describes where artists work. While "gallery" and "studio" may both look like potentially correct answers, a "gallery" is "a room or building for the display or sale of works of art," whereas a "studio" is "a room where an artist, photographer, or sculptor works." So, "studio" is the correct answer, because just as nurses work in hospitals, artists work in studios.
