The correct answer is 4. "Government of the people, by the people, and for the people"
Step-by-step explanation:
The purpose of parallelism is to sentences that are memorable and easy to read by using the same grammatical pattern or structure. A clear example of this is quotation 4 because the sections "of the people", "by the people", "for the people" follow the same grammatical pattern that includes a preposition (for, by, of), the article "the" and the noun "people". Moreover, the use of parallelism in this sentence shows all the ideas are equally important.
