Q. Which of the following groups often engaged in work slowdowns during the Civil War.
A. Enslaved African Americans
Francisco Vasquez de Coronado
Berbers.
The Berbers' history as a people in North Africa goes back thousands of years. In the ancient era (which is the time frame for the question you asked), the Berbers were influential as traders, establishing trade routes between North and West Africa and the sub-Saharan region.
Today, there are approximately 14 million Berbers living in Morocco, 9 million in Algeria, and additional populations of Berber descent in other parts of Africa.
It does make sense to me at least. The quote is basically telling you that you have an open mind or at least picking at that, I agree with this quote because it is true to what it is saying.
