OG 10/251 or OG11verbal review 72 greater/more的区别

dingxiang

251. The gyrfalcon, an Arctic bird of prey, has survived a close brush with extinction; its numbers are now five times greater than when the use of DDT was sharply restricted in the early 1970's. .

(A)                  extinction; its numbers are now five times greater than

(B)                  extinction; its numbers are now five times more than

(C)                  extinction, their numbers now fivefold what they were

(D)                  extinction, now with fivefold the numbers
     they had

(E)                  extinction, now with numbers five times
     greater than

A, the best choice, uses a singular pronoun, its, to refer to the singular antecedent The gyrfalcon, and it properly uses the construction its numbers are now ... greater than. In B, the construction its numbers are ... more is not idiomatic: there are more birds, but not more numbers. Choices C and D use a plural pronoun, their or they, to refer to a grammatically singular antecedent, The gyrfalcon. Choices D and E wrongly use a phrase introduced by now with to modify The gyrfalcon. In both choices, the phrase confusingly seems to parallel with extinction; a new clause with a present tense verb is needed to state what the gyrfalcon's numbers are now.

主要想问A/B的区别, 解释里面说B用more, 表示鸟儿有更多种群, 而非更多鸟, 而实际上原句的意思是鸟儿的数量增多,而非种群增多, 我想问more 表示种群增多,而greater表示数量增多呢?

为什么你说more 表示鸟儿有更多种群?解释里面并没有这么说呀?
我认为名词如bird, desk, chair和more, less搭配, number应和greater,smaller (bigger???) 搭配.不知对否?

BTW, A 为什么不是:

extinction; its numbers are now five times greater than there were


我记得GMAT OG 有的题就专门考这个,所以做这题的时候就先把A 排除啦!!! 结果我选了E, 我知道E指代不清不好,可A也不好呀???请NN指教!!!
