"Visible" means able to be "seen." So, to solve this analogy you need to determine which of these actions is described by "legible." Well, "legible" means (of writing) able to be "read."

The correct answer is "singer is to entertainment."

This analogy explores the relationship of what an individual provides through his or her occupation.

A doctor provides relief (from pain). A singer provides entertainment (to the general public).

“Tangible” is an adjective that can mean able to be physically touched, so if something is tangible, one can feel it. That means that we need to pick out an answer choice in which the first word is an adjective describing a quality, and the second word is a verb that conveys how one would experience that quality. “See is to visible” cannot be the correct answer, because “visible” would need to be the first word and “see” the second word to be correct. While “audible is to see” and “odorous is to smell” might each look like a potentially correct answer, one does not see things that are audible, one hears things that are audible, so “audible is to see” cannot be correct. One smells things that are odorous, however, just as one feels things that are tangible, so “odorous is to smell” is the correct answer.

The process by which something turns from a solid into a "liquid" is called "melting." So, to solve this analogy you have to determine which of these words means to turn something into a "gas." The correct answer is "evaporate." Additionally, "truncate" means shorten; "eradicate" means completely destroy; "fabricate" means fake, make up a story; "prognosticate" means make a prediction about the future.

“Illegible” is an adjective that consists of the negative prefix “il-“ and “legible,” so one might infer that it means “not readable.” That inference would be correct, as “illegible” means “not clear enough to be read,” so we need to pick out a verb that describes what you can’t do to something that is “incomprehensible.” “Incomprehensible” is a word that also consists of the negative prefix “in-“ and “comprehensible,” and because “comprehensible” means “able to be understood,” one might infer that “incomprehensible” means “not able to be understood.” That inference would be correct, as “incomprehensible” means “not able to be understood; not intelligible.” So, just as one cannot read something that is illegible, one cannot understand something that is incomprehensible, so “understand” is the correct answer.

When used as a noun, "trickle" means a slowly moving stream of a small amount of liquid, or when used as a verb, "trickle" can also refer to a small quantity of liquid and mean to move slowly. "Trickle" describes the movement of a stream, so to solve this analogy, you have to determine what body of water might be said to "meander." The correct answer is “river,” because "meander" means to move indirectly, following a twisting route, like a river.

“Abdicate” means give up a throne or position of power, so it is something a king could do_._ When an army does gives up power or withdraws from battle, it is said to "surrender," so "surrender" is the correct answer. As for the other answer choices, a “tactic” is an action or method used to achieve a goal, “lose” is to not win some competition or be defeated, a “skill” is an ability gained through training, and “worship” is the act of showing respect or admiration, especially to a deity in a religious context.
