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.

While I understand what this question is trying to say, and I answered it correctly, I think this is a poor question. Is it really true that the population would be INCAPABLE of surviving a natural disaster? Even if there is a .000001% chance of the population surviving, it still isn't incapable of surviving. Absolute language on CR questions is usually a major indicator that an answer choice is wrong. I think D would be a lot better stated, and more accurate, if it said "In the short term, the wild cheetah population would probably not survive a natural disaster in the African grasslands."

Yes I agree...the ans choice should sound more subtle than option D.

You are correct that the answer for these "draw a conclusion" questions will often be weak or trivial, but that is not a requirement. The real standard is to stay close to the precise wording of the argument and avoid answer choices that are STRONGER than the premises of the argument.

If you look at the premises here, you will find very strong language throughout: "size...must be...to survive", "too small", "not enough". These are very definitive statements and the answer choice isn't stronger than those premises.

That said, I agree that on the GMAT you would probably see a bit softer language, similar to what you have suggested. A good example of this is #103 - the Patria trade embargo question. The correct answer states: "Any trade embargo against Patria would be likely to fail at some time." Instead of absolute language like "will fail" the GMAT used "would be likely to fail".

hi... challenging question, at least for me (with wordy premises)
Even though i appreciate above experts explanation, i always wonder to what extent this kind of in-depth analysis would be feasible to in real GMAT test?

Here is my quick analysis at first glance

---------------------

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. - discusses only part of premises
(B) The cheetah's natural habitat is decreasing in size at a faster rate than is the size of the wild cheetah population. - rate at which population changes is out of scope
(C) The principal threat to the endangered wild cheetah population is neither pollution nor hunting, but a natural disaster. - pollution & hunting out of scope
(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. - 2 time frames (past decade & next decade) not within scope

WC live in AG.
previous estimates of the size of population - were too small aka few WC were needed to survive.
now - population barely meets the previous estimates. aka more WC are needed for them to survive.
now - not enough AG to support larger populations of WC.

now WC barely survives. if AG reduces even more, WC will not survive.

A. might be true..nothing to clearly state this.
B. rate the AG is decreasing vs. rate WC's population is decreasing is irrelevant.
C. out of scope..compares threads not discussed in the argument
D. yes, if AG decreases even more, the population of WC, which at the moment is barely enough for the WC to survive, will decrease even more..and thus..WC will become extinct.
E. out of scope.

D is the best.

fortunately, I was able to answer it in first attempt.

Many people are arguing that answer choices should be more specific and option D can be improved. But i think it doesn't matter , we are given with 5 options and there is not 'none of the above' choice... so our task is to find the best choice , not the best answer.

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.

What this question is basically saying is that if scientists claim " the cheetah population must be 100 in order for them to survive a natural disaster" when in reality it must be 1000 for them to survive a natural disaster, then if the population is somewhat close to the former estimate "100" like 99 cheetahs or 98 then it wouldn't survive a natural disaster. "barely meets previous estimates" means there would be like 98 or 99 cheetahs.

Is my reasoning faulty? The estimated population size for wild cheetah to survive natural disaster was small. And current population is below the estimate, and African grassland cannot sustain even that.
First. Congrats all the existing wild cheetahs. This is great news for you. Earlier you had your competition. Now you are few and free. Whoa!
However, what is the African Grassland has to do with that? May be to accommodate the Cheetahs. Wait! So do you mean that earlier the African Grassland was able to accommodate the estimated population, and now the current population is even low, and the Grassland is not even able to support that.
Therefore, the grassland must be shrinking, that too at a faster rate.

D says natural disaster in the short term. However, what has the natural disaster to do with the size of grassland? Why was natural disaster mentioned in the first place?

I think you haven't understood the argument properly.

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,

The previous estimates were too small. That means they were not accurate. The actual value of "the actual size that the wild cheetah population must be in order for these animals to survive a natural disaster in the African grasslands region" should be greater.

and the current population barely meets the previous estimates,

The current population is less than the pervious estimates.

At present, however, there is not enough African grassland to support a wild cheetah population larger than the current population.
But the grassland can support only current population, not larger.

So what will happen if there is a natural disaster in the near future?

The cheetah population is much less than that required to survive a natural disaster. So it will probably not survive.

What is the relevance of "short term"? We can't say the same thing about long term (because the cheetah population might grow).
