it gives the rest of the speech importance by referring to a famous historical document.

Explanation:

A rhetorical question is asked not for an answer but to make a point. Here, the question is about whether the principles of the Declaration of Independence (political freedom and natural justice) are extended to "us" (Black people). By asking this, it implies that the answer is no. It's a way to highlight the disparity. The other options don't align as well. The first option about discussing is not the main purpose. The third option about Douglass's knowledge is not the key contribution. The fourth option about giving the speech importance is not the main focus of this particular rhetorical question in terms of the central idea related to the rights of Black people.

Answer:

It reinforces the idea that the rights given to others are not extended to Black people.
