Which brought an end to the great west african empires?

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

b. the arrival of christianity and the decline of islam

c. enemy nations using sophisticated warfare to overpower the outdated tactics of the empire

d. emperors being unable to further the development of technology and learning

Songhai was conquered by Morocco, who had guns and warfare that overpowered them, so the answer is 'C.'  I got this right on my quiz.

Often with these questions there are two correct answers used depending on the school asking, so both these answers are correct; mine may be correct for one school and the other answer correct for a different school. Use your best judgement and reflect on what was reviewed in the lesson. One answer may refer to things brought up in your lesson and the other does not, so avoid that one. I hope this helps,  but if not, I'm sorry, I'm just trying to help :)

It is very important to our life
