OG-239

(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

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

答案是C, OG解释有说Neither A nor B produces the idiomatic phrase "... as many as, or more than, 250 ..."--a phrase that would be needlessly wordy here. 我不明白的是为什么是needlessly wordy 呢, 我反而觉得不加as many as倒是改变了原句的意思了!! 有没有人帮忙解释一下, 先谢谢了!!

我认为OG这里说得是more than已经表达了as.....as得意思，就是大于等于，所以不必要在加，就说needlessly wordy

同样在OG266中也有类似出现

266. In a recent poll, 86 percent of the public favored a Clean Air Act as strong or stronger than the present act.

(A) a Clean Air Act as strong or stronger than

(B) a Clean Air Act that is stronger, or at least so strong as,

(C) at least as strong a Clean Air Act as is

(D) a Clean Air Act as strong or stronger than is（E）

(E) a Clean Air Act at least as strong as

Choices A, B, C, and D may be faulted for constructions that are cumbersome, unnecessarily wordy,
