Answer: C. It caused some Americans to think about the fairness of slavery.
Step-by-step explanation:
While the American Revolution did not immediately abolish slavery, it did inspire some Americans to consider the contradiction between fighting for their own liberty and owning slaves. As a result, a growing number of people began to speak out against the institution of slavery, and several states took steps to gradually abolish it. The Northwest Ordinance of 1787 also prohibited slavery in the Northwest Territory, which included what is now the Midwest region of the United States. However, it would take many years and a bloody Civil War before slavery was officially abolished throughout the United States.
