(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
The answer is C.
C is the best choice. The phrase to monitor changes is idiomatic as a statement of purpose ([in order] to monitor), and the intended meaning is expressed concisely and accurately. Neither A nor B produces the idiomatic phrase "... as many as, or more than, 250 ..."--a phrase that would be needlessly wordy here. Also, for monitoring of in A is less concise and idiomatic than to monitor, and population changes in B is less precise than changes in population. In D and E, the pronoun that has no singular noun (required by the verb monitors) to which it can logically or grammatically refer. Survey already has its verb in uses, and no other noun can perform the action of monitors
为什么：produces the idiomatic phrase "... as many as, or more than, 250 ..."--
