The correct answer to this open question is the following
Although there are no options attached, we can say the following.
Equiano described the kind of slavery he knew in Africa as slavery that resulted from the wars, which means that slaves were considered prisoners of war and were used as slaves. The other form of slavery was the result of punishment when people committed crimes.
On the Other hand, the plantation slavery of the Americas? was the result of the slave trade in which African people were sold to work in the Americas. Africans were "packed" in ships. The overcrowded spaces made diseases spread quickly and many Africans died in inhuman conditions.
Olaudah Equiano's narrative shows slavery in the interaction among the peoples of Africa and Europe and how this impacted the course of slavery.
This reflects the way slaves were treated during those horrible years of slavery and the Slave Triangle that traded African slaves to the Americas. In 1789, Olaudah Equiano wrote the book "The Interesting Narrative of the Life of Olaudah Equiano, or Gustavus Vassa, the African," which describes his memories of being treated as a slave since he was 11 years old.
