Which of the following is an example of parallel structure?

The correct answer is an excellent example of parallel structure because it maintains a consistent grammatical format across the listed items. In this case, all three descriptors—"snowy," "windy," and "icy"—are adjectives that describe the blizzard. This uniformity in the part of speech creates a rhythm and clarity that makes the sentence easier to read and understand.

Parallel structure enhances the flow of the sentence and reinforces the ideas being presented. When each item in a list matches in grammar, it emphasizes the qualities of the subject—in this case, the blizzard—in a cohesive manner. The other options feature variations in structure that disrupt this parallelism: combining different grammatical forms or using inconsistent parts of speech detracts from the clarity and fluency of the description.
