The best way to describe the relationship between “cloak” and “covering” is that a cloak is used for covering oneself; therefore, the answer needs to describe the use of a trunk. While a trunk can be latched or locked, the only option that describes the actual purpose for a trunk is “storage.” (Recall that a trunk is a type of chest for storage, not merely the rear compartment in a car—thought that could be said to be used for storage as well).

Solder is a type of metal that easily melts; therefore, we could write the bridge sentence for this analogy as, “As solder is a type of metal, so is a treaty a type of X.” A treaty is an agreement, generally between two sovereign nations. Not all agreements are treaties. (A contract, for instance, is a type of agreement); therefore, “agreement” is the best option among those provided, for it alone provides a general class of which a “treaty” is a specific type.

When someone fortifies something, he or she strengthens it against potential attack or assault. The word comes from the Latin for “strong.” A fortification is something that has been strengthened against attack—for instance, a bunker or a castle. It can also refer to the walls and other things used to fortify the given area. Thus, a fortification is used for defense. The analogy could be read as stating, “As a fortification is used for defense, so is telephony used for X.” Telephony is merely “a system using telephones.” This would be used for communication.

A barometer is an instrument for measuring air pressure. When you hear of “barometric pressure,” this is referring to the pressure of the air and often indicates certain aspects of the weather. Now, if you did not know this, you might have been able to guess that we are dealing with something that measures in both cases of our words because they both contain the ending “-meter.” A “chronometer” is something that measures time. The “chronology” of events is the order in which they unfold in time, and “chronic” illness is one that lasts for a long period of time. While a watch and a clock might be chronometers, the analogy wants function, not examples.

The general relationship of this analogy is rather simple, but you need to know the meaning of the word “caching.” A “cache” of something is a hidden set of those items, often stored up for the future. The verb “to cache” merely means “to hide or store for the future.” A cupboard can at least be said to be used for this purpose, even if it has other purposes. For this reason, the analogous word for ladder must describe such functioning. The word “climbing” is best. Think of it this way: “Just as a cupboard can be used for caching, so too can a ladder be used for climbing.”

"Film" is the medium by which "photography" is expressd, just as "sculpture" is often expressed with "clay."

A brush is a tool used by a painter, so this analogy calls for the tool used by a musician. Among the options given, the only one that fits that need is “instrument.”

A "general" is the top leader of an "army," while an "admiral" is the leader of a "navy."

A "curator" is responsible for directing a "museum," just as a "director" is responsible for directing a "film."

Students are the group to whom a teacher directs his or her acts of teaching. A demagogue is a person who appeals to popular sentiment, often through oratory, to influence political decisions. The “dem-” in the word is related to the same form found in “democracy,” meaning “the people.” The sense of the word “demagogue” is that such a person uses oratory “on the crowd or throng of people” to whip them into a fury over something. Thus, a crowd stands in relation to a demagogue as a group of students stands to a teacher.
