SAT Vocab Builder

Answer: Choice (A) is correct.

In the first half of the analogy, paradigm and archetype are synonyms meaning an example that serves as a model. In choice (B), cloture is the process of ending debate by voting, which is unrelated to an enclosure. In choice (C), combustion means ignition or burning, while decorum means properness. These words are unrelated, so eliminate choice (C). In choice (D), a decree is an order given by an authority, while abdication means to give up. These words are not closely related, so eliminate that choice. In choice (A), something that is auxiliary is a support or a back-up. Choice (A) is the only choice with synonyms, so it is the correct choice.
