Final answer:
The sentence using parallel structure in the passage is about the changing practices of clothing ownership due to fashion trends, not just wear and tear. It showcases parallel construction with two reasons presented in a coherent manner.
Step-by-step explanation:
The passage that uses parallel structure is "People below the level of the rich came not only to own many different items of clothing, but they voluntarily replaced clothing due to shifts in fashion, not just because it was worn out." In this sentence, the parallel structure is created by using the phrases "came not only to own" and "but they voluntarily replaced," both followed by reasons for the changes in clothing ownership. This mirrors the construction and maintains a balance in the sentence.
The use of parallel structure is important as it adds clarity, balance, and emphasis to writing, making it more effective and engaging for the reader. Reading sentences aloud is a good technique to test the rhythm and clarity of your writing and to identify areas where parallel structure could enhance the flow.
