The answer is A.) As the populations of western kingdom grew, overpopulation caused citizens to migrate east and south to build new empires.

I think you're right. Let's see what Ms. Sue thinks. :)

Is it a or c? What does your text say?

To answer the question, we need to analyze the options provided and determine which one accurately describes the impact of the success of West African kingdoms on the development of kingdoms in western and southern Africa.

Option 1 suggests that overpopulation in the western kingdoms led to citizens migrating east and south to build new empires. This option does not accurately depict the impact of the success of the West African kingdoms, as overpopulation alone is not the main contributing factor to the development of new kingdoms in western and southern Africa.

Option 2 states that native citizens moved east and south to escape foreign influence as people from other continents came to find jobs in western empires. While external influences may have played a role in shaping the development of kingdoms, this option does not specify how the success of West African kingdoms directly contributed to the migration and establishment of new kingdoms in the east and south.

Option 3 suggests that trade for goods from distant lands flourished, leading native citizens to move east and south to discover new goods and people with whom to trade. This option seems to offer a more accurate explanation. The success of West African kingdoms could have facilitated economic and trade networks, encouraging migration and the establishment of new kingdoms in the eastern and southern regions to expand commercial activities.

Option 4 implies that the arrival of foreigners brought new diseases, leading citizens to migrate east and south to save their families. While the spread of diseases could have been a factor, it does not directly address the impact of the success of West African kingdoms on the development of kingdoms in eastern and southern Africa.

Based on the explanations, Option 3 - the flourishing trade leading citizens to move east and south to discover new goods and people with whom to trade - seems to be the most plausible answer.
