Answer: One grammatical feature in the paragraph is parallelism—the use of similar grammatical structures to create balance and clarity.Example:"Supporters argue for personal autonomy in euthanasia, justice in capital punishment, and self-defense in war."The three phrases ("personal autonomy in euthanasia," "justice in capital punishment," and "self-defense in war") follow the same structure (noun + prepositional phrase), making the sentence clearer and more effective.
