which sentence or sentences have correct parallel structure?\nin order to be elected to the u.s. senate, candidates must meet citizenship, residency, and age requirements.\nin order to be elected to the u.s. senate, candidates must meet a citizenship requirement, a residency requirement, and be at least thirty-three years old.
Answer
Brief Explanations:
Parallel structure requires matching grammatical forms in a list. The first sentence uses three consistent noun modifiers (citizenship, residency, age) paired with "requirements," creating parallelism. The second sentence mixes noun phrases ("a citizenship requirement," "a residency requirement") with a verb phrase ("be at least thirty-three years old"), breaking parallel structure.
Answer:
In order to be elected to the U.S. Senate, candidates must meet citizenship, residency, and age requirements.
