5. An advertisement for Paul Kennedy’s book Preparing for the Twenty-First Century (Random House, 1993) asked: “By 2025, Africa’s population will be: 50%, 150% or 300% greater than Europe’s?” The population of 740 million in Europe in mid-2015 was expected to increase 1%—not per year, just 1%—by 2025. The population of 1166 million in Africa in mid-2015 was expected to increase at about 2.6% per year. Which answer would you give to the question?
