Question

Which excerpt is a counterclaim in "What to the Slave is the Fourth of July?”
What is this but the acknowledgment that the slave is a moral, intellectual, and responsible being? The manhood of the slave is conceded.
There are seventy-two crimes in the State of Virginia which, if committed by a black man (no matter how ignorant he be), subject him to the punishment of death; while only two of the same crimes will subject a white man to the like punishment.
It is admitted in the fact that Southern statute books are covered with enactments forbidding, under severe fines and penalties, the teaching of the slave to read or to write.
What, then, remains to be argued? Is it that slavery is not divine; that God did not establish it; that our doctors of divinity are mistaken?

Answer 1

The fourth excerpt: "What, then, remains to be argued? Is it that slavery is not divine; that God did not establish it; that our doctors of divinity are mistaken?"

Why: This passage restates the opposing argument (that slavery is divinely ordained) so Douglass can confront and refute it—making it a counterclaim. The other excerpts are evidence supporting his main argument about the injustice and humanity of enslaved people.
