1.        Organized in 1966 by the Fish and Wildlife Service, the Breeding Bird Survey uses annual roadside counts along established routes for monitoring of population changes of as many as, or of more than 250 bird species, including 180 songbirds.

(A) for monitoring of population changes of as many as, or of

(B) to monitor population changes of as many, or

(C) to monitor changes in the populations of

(D) that monitors population changes of（C）

(E) that monitors changes in populations of as many as, or

请问C为什么可以把as amny as去掉，直接就用more than，这难道不是对句子意思的改变吗？

而且B选项少了一个as，应为as many (as)

2楼解释，我也在疑虑中。

我再问一下：

B答案中“population changes of as many, or”中的of 是不是从语法上修饰了changes，从而导致了错误

见 OG 239 ETS的解释。抛开别的错误，单从as many as, or more than 250......来看，它的意思是多余等于250，也许ETS认为此处more than 250 就可以说明问题。
