Document 5: Africa: Africans profess a wide variety of religious beliefs, and statistics on religious affiliation are difficult to come by since they are often a sensitive topic for governments with mixed religious populations. According to the World Book Encyclopedia, Islam is the largest religion in Africa, followed by Christianity. According to Encyclopædia Britannica, 45% of the population are Christians, 40% are Muslims, and 10% follow traditional religions. A small number of Africans are Hindu, Buddhist, Confucianist, Baha'i, or Jewish. There is also a minority of people in Africa who are irreligious.

Document 7: Nigeria: During the oil boom of the 1970s, Nigeria joined OPEC and the huge revenue generated made the economy richer. Despite huge revenues from oil production and sale, the military administration did little to improve the standard of living of the population, help small and medium businesses, or invest in infrastructure. As oil revenues fuelled the rise of federal subventions to states, the federal government became the centre of political struggle and the threshold of power in the country. As oil production and revenue rose, the Nigerian government became increasingly dependent on oil revenues and the international commodity markets for budgetary and economic concerns. It did not develop other sources of the economy for economic stability. That spelled doom to federalism in Nigeria.
Document 8: United States: The United States has a capitalist mixed economy which is fueled by abundant natural resources and high productivity. According to the International Monetary Fund, the U.S. GDP of $16.8 trillion constitutes 24% of the gross world product at market exchange rates and over 19% of the gross world product at purchasing power parity (PPP).The nominal GDP of the U.S. is estimated to be $17.528 trillion as of 2014. From 1983 to 2008, U.S. real compounded annual GDP growth was 3.3%, compared to a 2.3% weighted average for the rest of the G7. The country ranks ninth in the world in nominal GDP per capita according to the United Nations (first in the Americas) and sixth in GDP per capita at PPP. The U.S. dollar is the world's primary reserve currency.The United States is the largest importer of goods and second-largest exporter, though exports per capita are relatively low. In 2010, the total U.S. trade deficit was $635 billion. Canada, China, Mexico, Japan, and Germany are its top trading partners. In 2010, oil was the largest import commodity, while transportation equipment was the country's largest export. Japan is the largest foreign holder of U.S. public debt. The largest holder of the U.S. debt are American entities, including federal government accounts and the Federal Reserve, who hold the majority of the debt.
Document 9: Gabon: Abundant petroleum and foreign private investment have helped make Gabon one of the most prosperous countries in Sub-Saharan Africa, with the 7th highest HDI and the fourth highest GDP per capita (PPP) (after Mauritius, Equatorial Guinea and Seychelles) in the region. GDP grew by more than 6% per year from 2010 to 2012. However, because of inequality in income distribution, a significant proportion of the population remains poor.
