Question

which brought an end to the great west african empires?
an increase in countries producing their own goods and not needing to trade
emperors being unable to further the development of technology and learning
the arrival of christianity and the decline of islam
enemy nations using sophisticated warfare to overpower the outdated tactics of the empire

Explanation:

To determine what ended the great West African empires, we analyze each option:

• The first option: West African empires (like Mali, Songhai) relied on trade (e.g., gold - salt). If other countries started producing their own goods and stopped trading, the empires' economic base (trade) would collapse, leading to their decline.
• The second option: Emperors not advancing technology/learning was a factor but not the primary cause of their end.
• The third option: Islam was influential in West Africa, and Christianity’s arrival didn’t cause the empires’ end; Islam didn’t decline in a way that ended the empires.
• The fourth option: While warfare was a factor, the main decline was more economic (trade - based) than just warfare tactics. The trade - related collapse (first option) is more accurate as these empires thrived on trans - Saharan trade. So the correct option is "an increase in countries producing their own goods and not needing to trade".

Answer:

an increase in countries producing their own goods and not needing to trade
