A syllable is a component of a word, a single unit of sound. We say that words are comprised of a number of syllables; therefore, we could write a bridge sentence like, “Just as a syllable is part of a word, so is a buckle part of a X.” While a buckle could be said to latch, snap, fasten, or secure, it is a part of none of these words. It is a part of a belt, which is a whole thing that has a buckle on it; therefore, this is the best option among those provided.

The pane of a window is the glass portion that is placed in the window’s frame. It is not the whole window but merely part of it; therefore, you could write a bridge sentence like, “As a pane is part of a window, so a phase is part of a X.” A phase is a portion of some undertaking or procedure. For instance, a project could be said to be in “Phase 1,” “Phase 2,” “Phase 3,” etc, depending on how much of it has been completed thus far. A procedure is like a plan or outline for a project, and it can be broken up into phases.

While not all buildings have domes, all domes are placed upon the tops the buildings that have them. The best way to express this analogy is, “As a dome is on the top of a building, so is a capital on top of X.” While “capital” can mean the main city of nation or state, it likewise can mean the “head” of a column. Think of the columns that you have seen on some buildings. On the ends, there are designed “pedestals” of differing characters. These are the “capitals” on the columns. Just as a dome is on the top of a building, so is a capital on the top of a column. Do not be fooled by the other options that are tempting because of their general relationships to “capital.” None of them work correctly in the analogy.

The peak is the highest point of a mountain, and the consummation is the point of completion of some task or undertaking. While the word “goal” and “zenith” are potential synonyms for the word, the only acceptable option is “undertaking,” for it is an undertaking that reaches its consummation, as a mountain is “completed” by its peak.

A filament is a small fiber, thread, or wire. In the case of a “bulb” it must mean “wire,” particularly if “bulb” is understood as being short for “light bulb” (as it can be). Old-fashioned, incandescent light bulbs use a filament to produce light. Thus, the analogy could be written, “As a filament is used by a bulb to produce light, so is graphite used by X for its regular activity.” Graphite is the substance used in pencils for writing. The only instrument listed among the possible answers is “pencil,” so this is the correct choice.

A "balcony" has a "railing" to keep people safe, much like a "road" has a "guardrail" to keep cars and their drivers safe.

A group of "cattle" is called a "herd;" similarly a group of "seagulls" is called a "flock."

A confederation is a type of union of smaller groups, often indicating political entities. In the United States, the “Articles of Confederation” were the first legal constructs by which the states were gathered together into a single united group (at least for certain tasks and undertakings). A confederation can also take place among separate countries, and that is what is indicated in this analogy. Thus, one can translate this analogy as stating, “As a country is a member (or part) of a confederation, so is an organelle part of X.” As you might know from biology, an organelle is one of the small parts of a cell such as a ribosome or mitochondria. The word literally means “little organ.”

Ore is a type of stone-metal mixture from which metals and minerals can be extracted. The analogy could be written, “As iron can be extracted from its mixed state in ore, so salt can be extracted from its mixed state in X.” Among the options provided, only “brine” describes such a mixture. Brine is water that is saturated with salt. If someone wished, he or she could remove salt from brine as one would remove iron from ore.
