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
This version is not perfect, in that "20,000, ten times the estimated population of 2000" is a little awkward and does not make complete sense, but basically it logically compares 20,000 with 2000.

(b) that of their estimated population
This choice has two issues. First there is no logical antecedent for "that". Ten times what of the estimated population? Second, though there are multiple black rhinos in the population of black rhinos, in the sentence itself, there is no logical antecedent for "their".

(c) more than the population's estimated amount
"ten times more" is not logical. The point is that 20,000 is ten times 2,000. "ten times more", if it means anything, means eleven times, and eleven times 2000 is 22,000, not 20,000. "amount" does not correctly refer to a countable number. Also, "the population's estimated amount of 2,000" is awkward and does not clearly convey that the number of rhinos in the population was 2,000.

(d) more black rhinos than their population estimate
This version repeats the "ten times more than" error seen in C, and "their" has no logical antecedent. Also, this version illogically compares "black rhinos" to "their population estimate of 2000".

(e) more than that of their population's estimated amount
This version repeats the "ten times more than" flaw and the "amount" error seen in C. "that" is unnecessary and has no logical antecedent. "their" has no logical antecedent. The entire choice is unnecessarily wordy and does not directly compare 20,000 with 2,000, but rather compares 20,000 with "that of ... 2,000", a comparison that conveys nothing that makes sense.

The best answer is A.

(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.

Hi egmat

Bit confused while applying comparison here.
Initial no: In 1997, 2000
Mid 1970: 20,000 (10 times of 2000)

More than phrase in C,D and E suggests value more than 20,000 in mid 1970s which is incorrect.

For (B) does that jump over noun ten times and
noun phrase in the mid-1970's numbered about 20,000, to suggest illogical
comparison between rhino population and esteemed population.

WR,
Arpit.

(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

[Reveal] Spoiler:
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?
