Africa's black rhino population in the mid-1970's numbered about 20,000, ten times the estimated population of 2,000 in 1997.

(b) that of their estimated population
(c) more than the population's estimated amount
(d) more black rhinos than their population estimate
(e) more than that of their population's estimated amount

Subject is the population, option B, D and E are out because they are refering to rhinos as subject.Option C is out because it is wrongly constructed also distorts the meaning.

We are left with option A which is alos the correct choice.

(A) the estimated population
(B) that of their estimated population
(C) more than the population's estimated amount
(D) more black rhinos than their population estimate
(E) more than that of their population's estimated amount

Please provide explanations why each answer should be ruled out.


A small doubt

If correct answer is A

Then how do we know that

TEN TIMES (THE ESTIMATED POPULATION ) of 2000 in 1997


Ten times? What? More or Less?

How can we tell that we need more or not? Becoz if we dont use more then it can be TEN TIMES LESS

isn't it?

(a) the estimated population--- a quantity compared with another quantity: correct comparison and correct choice.
(b) that of their estimated population ---- The problem is the plural pronoun ‘their’; there is no justification for using a plural
(c) more than the population's estimated amount ---- ‘ten times as x means 10x; ten times ‘more than x’ means 11 x
(d) more black rhinos than their population estimate--- same as C ; in addition the problematic ‘their’
(e) more than that of their population's estimated amount --- same as that of D.

Can we eliminate options B and D on the basis of the pronoun that ?
"that" takes a singular noun(population). So the sentence looks like
"Africa's black rhino population in the mid-1970's numbered about 20,000, ten times population of their estimated population of 2,000 in 1997."
Is this a correct approach?

Yup, that's exactly how I would think of it. The only singular noun "that" could possibly refer back to is the population. So for (B), we get "...ten times the population of their estimated population", exactly as you said. For (E), we get "...ten times more than the population of their population's estimated amount." Both are pretty ridiculous. (And "their" is a problem in both of those too, for whatever it's worth.)

The GMAT seems to love using "that" as a pronoun for some reason, so I promise that you'll see this again. :-)

GMATNinja Could you please help with my query for pronoun ambiguity. As of now, in reference to GMAT, I feel that Possessive pronoun can refer possessive noun. So, if my understanding is correct, then please tell me whether "their"in this SC problem can refer "Black Rhinos' ".

Quote:
Africa's black rhino population in the mid-1970's numbered about 20,000, ten times the estimated population of 2,000 in 1997.

(A) the estimated population
(B) that of their estimated population
(C) more than the population's estimated amount
(D) more black rhinos than their population estimate
(E) more than that of their population's estimated amount


In (B) and (E), there's absolute no chance that "their" could refer to "black rhinos". Why? The phrase "black rhinos" doesn't actually appear in either of those answer choices. We have "Africa's black rhino population" in the non-underlined portion, and that's unambiguously singular. The sentence says "Africa's black rhino population", not "the black rhinos' population". So "their" is wrong in both (B) and (E).

In (D), "their" actually HAS to refer to "black rhinos", since it's the only plural noun that appears earlier in the sentence. But that still doesn't make sense: "Africa's black rhino population in the mid-1970's numbered about 20,000, ten times more black rhinos than [the black rhinos'] population estimate." It's pretty messy and illogical to compare the number of black rhinos to "the black rhinos' population estimate." It's also weird to suggest that the rhinos somehow "possess" a population estimate.

I hope this helps!
