　　托福阅读修辞目的题：Succession

　　【Paragraph 5】Even less fortunate was the extension of this type of thinking to include animals as well as plants.　This resulted in the "biome," a combination of coexisting flora and fauna. Though it is true that many animals are strictly　　associated with certain plants, it is misleading to speak of a "spruce-moose biome," for example, because there is no　　internal cohesion to their association as in an organism. The spruce community is not substantially affected by either the　　presence or absence of moose. Indeed, there are vast areas of spruce forest without moose. The opposition to the　　Clementsian concept of plant ecology was initiated by Herbert Gleason, soon joined by various other ecologists. Their　major point was that the distribution of a given species was controlled by the habitat requirements of that species and　that therefore the vegetation types were a simple consequence of the ecologies of individual plant species.(Succession,　Climax, and Ecosystems)

　　Why does the author make the statement, “Indeed, there are vast areas of spruce forest without moose” ?

　　○ To highlight a fact whose significance the ecologist Herbert Gleason had missed

　　○ To propose the idea that a spruce forest is by itself a superorganism

　　○ To emphasize that moose are not limited to a single kind of environment

　　○ To criticize the idea of a spruce-moose biome
