Hello! The slavery in the United States was one of the most violent and inhuman of all times, but is wrong to affirm that white people were sold into slavery for debts, or that US was the first country to use this compulsory system (the arabs and Portugal, for example, bought slaves at least two centuries before). The right answer is: "C) Slavery contradicted the ideals of freedom on which the nation was founded.". Hugs!
