'that of' - pronoun - antecedent? population? wolf?
'their' - pronoun - antecedent? do we have any plural pronoun here? 1000?
let's imagine some sinarions:
four times wolf of their estimated population in 2004 -
illogicalfour times population of 'wolves' estimated population in 2004 - more or less makes sense, but we don't have plural 'wolves' in the sentence.
POE
We can eliminate (A), (D), and (E) because of 'their'
In (D) even if we have plural 'wolves' this sentence doesn't make any sense.
(A) four times that of their estimated population
(D) four times more wolves than their population estimate
(E) four times more than that of their population's estimated amountBetween (B) and (C)
'more than' in C is good, but 'amount' cannot go with population, 'population' cannot be counted in terms of 'amount' event if 'amount' is used with uncountable nouns, 'population' itself represents numerical meaning.
(B) four times the estimated population
(C) four times more than the population's estimated amount(B) four times the estimated populationAttachment:
