The principles outlined in the Declaration of Independence emphasize that all men are created equal and are endowed with unalienable rights, including life, liberty, and the pursuit of happiness. Given this context, the following facts about slavery in the United States directly conflict with those principles:
A. Slaves could not vote on the government.
D. Slaves were not paid for their labor.
E. Slaves were not free to pursue their interests.
These options highlight the denial of rights and liberties to enslaved individuals, which contradicts the assertion of equality and unalienable rights made in the Declaration of Independence.
