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 exploitative nature of colonial practices in Africa, particularly in the Congo Free State under Belgian rule, and recognizes the economic challenges faced by Cuba as it sought to modernize its sugar production, often leading to indebtedness.
