Final answer:
The speech "What to the Slave is the Fourth of July?" uses inductive reasoning by starting with observations about a specific holiday to construct broader conclusions about the state of slavery.
Step-by-step explanation:
The statement that best explains why "What to the Slave is the Fourth of July?" is an example of inductive reasoning is that it uses a specific holiday as a basis for the broader conclusion that is constructed throughout the rest of the speech. This type of reasoning is based on the method of starting with specific observations or instances and then constructing broad generalizations or conclusions from them, which matches the pattern of Frederick Douglass's speech. Throughout the speech, Douglass elaborates on the irony and the contrast between the freedom celebrated on the Fourth of July and the lack of freedom experienced by slaves, drawing from specific examples of the holiday celebrations to make a general statement about the condition of slaves in America.
