Final answer:
The Narrative of the Life of Frederick Douglass demonstrates the use of situational, verbal, and dramatic irony.
Step-by-step explanation:
The Narrative of the Life of Frederick Douglass demonstrates all three types of irony: situational irony, verbal irony, and dramatic irony. Situational irony can be seen in the contrast between the expectation and the reality of Douglass's enslaved existence. Verbal irony is employed when Douglass uses language in a way that emphasizes the stark contrast between his situation and the expectations of white society. Dramatic irony arises from the reader's awareness of the larger historical context of slavery, while Douglass remains unaware of how his story will impact the future.
