Wild cheetahs live 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 present, however, there is not enough African grassland to support a wild cheetah population larger than the current population.

Summary
Cheetahs live in African grasslands. Previous estimates of the size of the cheetah population must be in order to survive a natural disaster were too low. The current population of cheetahs barely meets the previous estimates. Currently, there is not enough African grassland to support a cheetah population larger than the current one.

Strongly Supported Conclusions
Currently, the cheetah population will be unable to survive a natural disaster.

A
Previous estimates of the size of the existing wild cheetah population were inaccurate.
This answer is unsupported. It’s not that the estimate of the size of the cheetah population was inaccurate. Rather, it was the estimate of the population needed to survive a natural disaster that was inaccurate.
B
The cheetah’s natural habitat is decreasing in size at a faster rate than is the size of the wild cheetah population.
This answer is unsupported. We don’t know from the stimulus whether the cheetah’s natural habitat is decreasing in size. We only know that the current habitat is incapable of supporting a larger cheetah population than the current one.
C
The principal threat to the endangered wild cheetah population is neither pollution nor hunting, but a natural disaster.
This answer is unsupported. We don’t know from the stimulus what the principle threat against the cheetah population is. We know that a natural disaster is a threat, but we don’t know if a natural disaster is the principle threat.
D
In the short term, the wild cheetah population will be incapable of surviving a natural disaster in the African grasslands.
This answer is strongly supported. If the current habitat cannot support a cheetah population larger than the current one, and the cheetah population is too low to survive a natural disaster, then the current cheetah population cannot survive a natural disaster.
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.
This answer is unsupported. We don’t know from the stimulus where natural disasters are expected to occur, if any disasters are expected to occur at all.
