Explanation:

The rhetorical question is asking if the principles in the Declaration of Independence (political freedom and natural justice) are given to "us" (Black people). Since it's a rhetorical question (not expecting a real answer), it implies the answer is no. This supports the idea that Black people don't have those rights. The other options are incorrect: there's no indication of encouraging discussion (first option), showing knowledge (third option) or giving speech importance (fourth option) as the main contribution to the central idea.

Answer:

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