Nelson Mandela helped end apartheid, so A is incorrect. B would be right, but the white population is the minority in South Africa, not the majority. It ended in 1991, so C is not right. This leaves us with D, the correct answer. I hope this helps!

One exmaple of Jefferson using military force is when he sent The Navy, Marines to defeat Muslim terrorist. Jefferson had written a couple of reports on the 'Barbary pirates' when he was a diplomat and believed their demands kept escalating because the only thing they understood was power," Brian Kilmeade, co-author with Don Yaeger of "Thomas Jefferson and the Tripoli Pirates," told IBD. "Although the U.S. Navy was tiny when he became president, he wasn't intimidated by the pirate fleets and decided the challenge required a military response. The First Barbary War was America's first confrontation with Islamic terrorism, and it has lessons for today."
Opinion or bias can cause the outcome of an experiment to be incorrect because it’s based off of a personal preference. That being said, any desirable outcome can be produced. One example of this would be human reproduction. Let’s say a person of Cuban race wants a mixed child. They would decide not to marry a Cuban spouse because it’s biased that the offspring will be only one race. Therefore, they would marry a person of a different race to provide a desirable outcome, which in this case, would be a biracial child. Bias leans a result toward one side, preferably the result desired. That’s how opinions and biases can cause the outcome of experiments to be incorrect.
