Final answer:
The parallel structure in the poem is found in the line 'It's not the wind or the noise or the water,' using a repetitive pattern to emphasize the point.
Step-by-step explanation:
The parallel structure in the given excerpt from Problems with Hurricanes by Victor Hernandez Cruz can be found in (a) "It’s not the wind or the noise or the water." This sentence displays parallelism through a repetitive structure, listing things that aren't the cause of concern during a hurricane, using the same pattern: 'not the [noun].' This pattern establishes a rhythm and emphasizes the point that, within the context of the poem, the wind, noise, and water are not as feared as an unexpected object, such as a mango, becoming a deadly projectile. The lines following this excerpt break from the parallel structure to deliver a contrasting idea, making the initial parallel structure stand out.
