Question

which of these events occurred during the ghana empire?
moroccan invaders conquered the empire.
islam was introduced into the west african region.
timbuktu was developed into a center of learning
a large amount of technology was developed

Explanation:

To determine the event during the Ghana Empire:

• Moroccan invaders conquered the Songhai Empire, not Ghana.
• During the Ghana Empire, trade (including with Muslim traders) led to Islam's introduction to West Africa.
• Timbuktu’s rise as a learning center was in the Mali Empire.
• Major technology development in West Africa came later (e.g., post - trans - Saharan trade expansions in other empires). So the event matching the Ghana Empire is Islam’s introduction to West Africa.

Answer:

Islam was introduced into the West African region.
