Final answer:
Option A from 'The American Crisis' uses parallelism by employing a consistent grammatical structure across multiple sentences, enhancing the author's message of personal resolve and understanding of the situation.
Step-by-step explanation:
The excerpt from The American Crisis by Thomas Paine that uses parallelism is option A: "I thank God, that I fear not. I see no real cause for fear. I know our situation well, and can see the way out of it." This section employs a parallel structure by starting each sentence with a first-person statement and maintaining a similar grammatical form throughout, which emphasizes Paine's resolve and clarity of thought.
Parallelism is a rhetorical device where parts of the sentence are grammatically the same, or are similar in construction. It can be a word, a phrase, or an entire sentence repeated.
