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.
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.

(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.

Premise -1) 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
2) Current estimate of size is smaller than previous estimates.
3) If the current size grows, the african natural habitat would not be able to support it.

Now, we need to find the conclusion to these premises based on the info provided. Lets go over the options

A. Previous estimates of the size of the existing wild cheetah population were inaccurate. - This stmt does not serve as the conclusion to the above premises as we are talking about the current size of the wild cheetah population and their survival.
B. The cheetah’s natural habitat is decreasing in size at a faster rate than is the size of the wild cheetah population. Even though the passage suggests that the natural habitat may not be able to support an increase in the current population, it does not mean that the habitat is decreasing, that too at a faster rate than the wild cheetah population size.
C. The principal threat to the endangered wild cheetah population is neither pollution nor hunting, but a natural disaster. The passage does mention natural disaster but nothing about pollution or hunting
D. In the short term, the wild cheetah population will be incapable of surviving a natural disaster in the African grasslands. If the previous size estimates were small enough to not escape a natural disaster, the current size would surely not survive - Correct answer
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. Out of scope.

I did not pick the correct OA but I agree with D.

Lets say for example....

The estimates were that there should be a population of 20 wild cheetahs to survive a natural disaster.

The current population barely meets the estimates. Means the current population is no where close to 20 cheetahs....may be currently there are only 6 wild cheetahs as part of cheetah population.

That means in the short run the wild cheetah population will not be capable of surviving a natural disaster in the African grasslands.

Argument:

They estimate that wild cheetah is abuot XX size to survive the natural disater.
Currently the size of WC is YY < XX.
Now, there is not enough grass to support the current YY Wild Cheetah.

A - No indication that the estimate is inaccurate

B - The rate of decreasing was not discussed

C - Hungting and pollution were not discussed - Out of scope

D - not enough food for YY => YY will still < XX => Wild cheetah will not survive natural disater -> CORRECT

E - Next decade and past decade were not discussed - Out of scope

not enough African grassland to support a wild cheetah population larger than the current population. even more accurately reinforces this situatation

not so straight but still D . took 2:18 min and had to use POE to eliminate options . only D could stand hence D .
'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' ,

can some body explain what was too small here and why such stupid language was used ?

Close call between B and D.

The population required to survive the natural disaster is small here.As the grasslands are not enough to support a lager population the Cheetah's are bound to be extinct if a natural disaster happens in short term.

+1 for D.

Premise 1: "size of population ...too small.." => means that the requirements were already less than appropriate.
Premise 2: Current population = previous estimates
Premise 3: Population can't increase further as habitat is limited

Conclusion : If a disaster happens in near future, wild cheetahs will be extinct.
