The passage is primarily concerned with______
It can be inferred from the passage that the author describes coral reef communities as paradoxical most likely for which of the following reasons?
选项
A、They are thriving even though human activities have depleted the nutrients in their environment.
B、They are able to survive in spite of an overabundance of algae inhabiting their waters.
C、They are able to survive in an environment with limited food resources.
D、Their metabolic wastes contribute to the degradation of the waters that they inhabit.
E、They are declining even when the water sur-rounding them remains clear.
答案
C
解析
To answer this question, you must use information contained in the passage to draw an inference about why the author labels coral reef communities as paradoxical. The bet answer is C. In line 3, the author calls coral reefs “one of the fascinating paradoxes of the biosphere.” The author goes on to explain the nature of this paradox: the “prolific and productive” coral reef communities survive in nutrient-poor waters. Choice A contradicts information presented in the passage. The second paragraph indicates that human activities have increased, not decreased, the nutrients in coral reef communities’ waters, and that this increase has threatened the survival of such communities. Choice B does not present a reason why the author describes coral reef communities as paradoxical. In addition, lines 18-20 of the passage indicate that an abundance of algae is a symptom of reef decline, not reef survival. Choice D does not describe a paradox, and it misrepresents information presented in the passage. Lines 7-10 indicate that the metabolic wastes of coral reefs are used by zooxanthellae to carry out photosynthesis, thereby sustaining themselves and the coral reefs. Choice E contradicts information presented in the passage. Lines 2-5 indicate that coral reef communities thrive in “clear, and thus nutrient-poor, waters.” However, they have begun to decline because of an addition of nutrients in their waters, thus suggesting that the water surrounding them is no longer as clear.
