66. (28087-!-item-!-188;#058&003498)
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

KEY A

请问B，如果把their改为its，即 that of its estimated population,是否可以呢？
A　是将Africa's black rhino population和the estimated population比较；
B　将 about 20,000和that of its estimated population比较可以成立吗？

谢谢呀！

times 倍数后面可以直接跟名词的,表示该名词的几倍, 所以B里面用that反而错误指代了times.
