What commodities were central to the trans-Saharan trade that helped West African empires stabilize their economies?

• A. Gold and salt
• B. Silk and spices
• C. Timber and furs
• D. Tea and porcelain

Answer: (A)

The main idea is that West African empires grew stable, tax-based economies by controlling the gold-salt trade across the Sahara. Salt was scarce in West Africa and essential for food preservation and health, while gold from West African forests was highly desired in North Africa and beyond. Caravans carrying these two goods brought in steady revenue, which rulers levied through taxes, funded armies and administration, and supported urban centers like Timbuktu. This combination of lucrative, high-volume trade and centralized control explains the economic stabilization of these empires. Other options describe goods associated with different trade networks and regions, not the trans-Saharan corridor that shaped West African commerce.
