问题     This is not to say that precise harmonies are not present within communities. Most flowering plants could not exist were it not for their pollinators—and vice versa. Predators, disease organisms, and competitors all influence the abundance and distribution of everything from oak trees to field mice. But if we see a precise balance of nature, it is largely an artifact of our perception, due to the illusion that nature, especially a complex system like a forest, seems so unchanging from one day to the next.
Which of the sentences below best expresses the essential information in the highlighted sentence in paragraph 6? Incorrect choices change the meaning in important ways or leave out essential information.
选项 A、We see nature as precisely balanced because nature is unchanging.
B、A precise balance of nature is not possible because of the complexity of natural systems.
C、Our sense that nature is precisely balanced results from the illusion that it is unchanging.
D、Because nature is precisely balanced, complex systems do not seem to change.
