Read the passage below and answer the questions that follow: "The Okavango Delta in northern Botswana is one of the world's premier inland water systems.

However, environmentalists warn that upstream dam construction and climate change threaten the delicate ecological equilibrium of this UNESCO World Heritage Site." According to the passage, what primary source feeds the annual flooding of the Okavango Delta?
