The most accurate list that explains the primary economic impact of imperialism on Africa and Latin America is:
• The Congo Free State in Africa was impacted by exploitation by Belgium.
• Cuba in Latin America was impacted by debt incurred in an effort to mechanize sugar production.
This response highlights the direct impact of European exploitation in Africa through the brutal policies implemented by Belgium, specifically under King Leopold II, while also addressing the economic challenges faced by Cuba due to the costs associated with mechanizing its sugar production, which were influenced by imperialist pressures.
