Answer:
B) People realized that educated slaves were dangerous.
Sectional differences between the North and the South on the
issue of slavery grew stronger.
Explanation:
The North did not support slavery and as a result, tried to free Burns. In the attempt of liberating Burns, a guard was killed and none were convicted; however, the attempt was unsuccessful. Burns was ordered to return to Norfolk, Virgnia by Judge Edward Greely Loring. It was only then that the South believed that the North could not fulfill their obligation to protect and defend the Constitution of the United States.
