Final answer:
Increasing restrictions on importing automobiles and electronics is likely least effective in spurring growth in Africa, while increased public education, peace, and foreign investment can promote economic development. The World Bank has controversially supported the privatization of public utilities. Therefore, the correct option is B.
Step-by-step explanation:
Among the given government policies, the one least likely to increase economic growth in Africa is b. increase restrictions on the importing of Japanese automobiles and electronics. This is because such protectionist measures can lead to inefficiencies and higher costs for consumers and businesses, which can hamper economic development. On the other hand, policies like increasing expenditures on public education, eliminating civil war, and reducing restrictions on foreign capital investment are generally considered to promote growth by enhancing human capital, improving the investment climate, and providing a more stable environment for development.
Regarding the policy supported by the World Bank, option b. increased privatization of public utilities is a policy that has been controversially supported by the World Bank around the world. While privatization can lead to more efficient management and improved services in some cases, it can also lead to a decrease in access to essential services for poorer segments of the population if not properly managed.
