Question

what was one problem unique to free african americans in the 1700s?
they were not allowed to travel freely.
they could be kidnapped and sold into slavery.
they could not choose where to work.
they were not allowed to seek an education.

Explanation:

Free African Americans in the 1700s faced the threat of being kidnapped and sold into slavery. This was a unique problem as even though they were free, there was no strict legal protection against such a heinous act. Other groups (like white indentured servants who became free) did not face this specific threat of re - enslavement. Travel restrictions, limited work choices, and lack of educational opportunities were also problems for many marginalized groups (not just free African Americans) in the 1700s.

Answer:

They could be kidnapped and sold into slavery.
