Concept:Parallelism is the repetition of similar grammatical structures in a line or passage for rhetorical effect.
Explanation:The line lists actions as "to investigate," "to conciliate," "to hold hearings," and "to order."
Each action begins with the infinitive marker "to" followed by a verb, forming an identical syntactic pattern.
This deliberate repetition of the same grammatical construction creates rhythm and balance in the sentence.
It also makes the expression more forceful and easier for the audience to remember.
The device used here is not irony, since there is no contradiction between appearance and reality.
It is not personification, because no human qualities are given to objects or ideas.
It is not hyperbole, because no deliberate exaggeration is present.
Therefore, the repetition of the "to + verb" structure clearly illustrates parallelism.
