Answer: Parallelism and pathos.
Explanation: When writing, an author can use several rhetorical devices in order to persuade, inform or impact the audience in the desired way. Parallelism is a rhetorical device that consists in the repetition of the grammatical structure of different words or phrases in a sentence or paragraph, in order to emphasize an idea or to create an impact in the audience. Pathos is an appeal to the audience's emotions. The given sentence uses parallelism in the phrase "give me liberty, or give me death" and it helps to appeal to the reader's emotions.
