69. 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 C is correct. "to monitor" to introduce a clear statement of purpose;"changes in the populations of" is precise;wordiness has been eliminated. 但是原句里的As many as和more than是不同的程度啊，为什么as many as可以省略呢？不是说要忠实于原文的意思嘛～ 求教！！谢谢～
