4. For a long time, scholars incorrectly believed the Swahili city-states in east Africa must have been founded by Arabs,
rather than local Africans. Why did they believe that, according
to John Green?

He claims that sub-Saharan African histories were preserved by oral tradition rather than a written account. This is important because many deviations occur when oral traditions are passed down. In fact, he argues about prejudice occuring in oral tradition. Therefore, scholars incorrectly believed that Swahili city-states must have been founded by Arabs. There was Arabic influence, but that isn't the correlation of the relationship.
