2. Wild cheetahs lie in the African grasslands. Previous estimates of the size that the wild cheetah population must be in order for these animals to survive a natural disaster in the African grasslands region were too small, and the current population barely meets the previous estimates. At presents, however, there is not enough African grassland to support a wild cheetah population larger than the current population.
The statements above, if true, most strongly support which one of the following conclusions?
a. previous estimates of the size of the existing wild cheetah population were inaccurate.
b. The cheetah’s natural habitat is decreasing in size at a faster rate than is the size of the wild cheetah population.
c. The principal threat to the endangered wild cheetah population is neither pollution nor hunting, but a natural disaster
d. In the short term, the wild cheetah population will be incapable of surviving a natural disaster in the African grasslands.
e. In regions where land is suitable for cheetah habitation, more natural disasters are expected to occur during the next decade than occurred during the past decade.
