"Ivory" is a precious material that comes from "elephants," just as valuable "pearls" come from "oysters.

"Orchards" are the place where "apples" are grown; therefore "vineyards" are where "grapes" are grown.

"Steel" is made of raw "ore," just as "rubber" is made from "sap."

In days past, a portrait would be painted by a painter. It was the thing created by the painter; therefore, this analogy is one of “maker to thing made,” as though to say, “As the painter makes a portrait, so a composer makes X.” Among the options provided, only “symphony” describes what a composer would make. He would write the musical score for the symphony, which can just be called “a symphony” indicating the musical score itself.

A scribe is a person who writes a text by hand. The word “scribe” is not only related to the “script” found in “manuscript” but also to “scribble,” “ascribe,” and “inscribe.” It comes from the Latin for to write. The analogy could be read, “As a scribe works on a manuscript, so a cobbler works on X.” The only option here is “shoe,” for the other words are attempting to have you think of a simple synonym for the dessert known as “cobbler” or a description of a cobbler as a repairman. Although we generally say that scribes produce manuscripts and that cobblers merely repair shoes, the analogy does hold when we use the broader sense noted above, namely that of “working on.”

A ruler is a tool that allows you to measure.  So we must look at the second part as "wrench is a tool that allows you to _____". The main purpose of a wrench is to tighten or loosen nuts and bolts.  So either tighten or loosen would be correct answers, and tighten is the only word present here.

The sense of this analogy is that as a knife is used for cutting, so a pencil is used for writing. The other options are wrong for a number of reasons. Graphite is what allows the pencil to write, not the act one does with the pencil. The pencil is an instrument, but that doesn’t describe the action. Not even “writer” is appropriate, for that would describe who would use the pencil, not what one does with it. Finally, paper is that upon which you write, not the actually act itself.

Since it is safe to say that the general purpose of a vehicle is to transport things, we can say that the general purpose of a tractor is to haul. Now, you might think of the general uses and location of tractors on agricultural lands and become confused. First, note that the word “tractor” comes from Latin roots meaning “to pull” or “drag.” To “extract” something is to “pull it out.” None of the other words describe an action performed by a tractor. Certainly tractors are used in fields, to haul crops, in agricultural activity, and often have trailers attached. However, none of these words are verbs or directly descriptive of action.

The purpose of a vault is to protect items, so the analogy implies that we need to pick the best description of the purpose of an icebox. The best option here is “chilling,” for that describes the actual thing “done” in or by iceboxes. While they are used to protect food and prevent spoilage, neither of these options describe the actual purpose of the box. Perhaps if the word “preserve” were an option, it would be difficult to choose between chilling and preserving. This is not an issue here, as no other action is offered as a potential answer.

Although both razors and mowers cut things, the analogy can be read as being even more general than, “As a razor cuts hair so a mower cuts . . .” You could also read it as, “As a hair is the proper object of the razor, so too is . . . the proper object for a mower.” While we can use “mower” in a broad sense, the answer options help us to see exactly what is wanted for this question. None of the other options are related to mower in the same manner as hair is related to a razor. While we might store mowers in garages, use them in the summertime, see them in rural places, or run them weekly, none of these options are “acted on” like hair is “acted on” by a razor. For this reason, the simple answer “grass” is the best option.
