　　托福阅读修辞目的题：Deer Populations

　　【Paragraph 4】Reduction in numbers of game should have boded ill for their survival in later times. A worsening of　the plight of deer was to be expected as settlers encroached on the land, logging, burning, and clearing, eventually　replacing a wilderness landscape with roads, cities, towns, and factories. No doubt the numbers of deer declined still　further. Recall the fate of the Columbian white-tailed deer, now in a protected status. But for the black-tailed deer, human　pressure has had just the opposite effect. Wildlife zoologist Helmut Buechner(1953), in reviewing the nature of biotic　changes in Washington through recorded time, says that "since the early 1940s, the state has had more deer than at any　other time in its history, the winter population fluctuating around approximately 320,000 deer (mule and black-tailed　deer), which will yield about 65,000 of either sex and any age annually for an indefinite period." (Deer Populations of　the Puget Sound)

　　Why does the author ask readers to recall “the fate of the Columbian white-tailed deer” in the discussion of　changes in the wilderness landscape?

　　○To provide support for the idea that habitat destruction would lead to population decline

　　○To compare how two species of deer caused biotic changes in the wilderness environment

　　○To provide an example of a species of deer that has successfully adapted to human settlement

　　○To argue that some deer species must be given a protected status
