Question

what characteristic do the settlements located at letters b, d, and e on the map share? they represent bantu migrations. they represent swahili trading cities. they represent city - states of great zimbabwe. they represent city - states governed by persian and arab merchants.

Explanation:

The settlements at B, D, and E are located along the eastern - coast of Africa. These areas were known for the Swahili trading cities which thrived due to their strategic coastal location for trade with the Indian Ocean world. The Bantu migrations were more of a large - scale movement of people across a wider area of Africa, not specifically related to these coastal settlements. Great Zimbabwe was an inland kingdom, not these coastal locations. And while there was Persian and Arab influence in the region, these settlements were not city - states governed by Persian and Arab merchants but rather part of the Swahili trading network.

Answer:

They represent Swahili trading cities.
