问题 Some attine ants carry vegetation into their nests and add fungal material, thereby creating “gardens” in which fungal food for the ants grow. Because the ants play the behaviorally active role, it seems compelling to say that they cultivate and control the passive fungi. But even if that is true, the symbiotic association has existed for so long that cultivar traits may have evolved in the fungi that benefit the fungi but not necessarily the ants. Furthermore, many microorganisms have developed sophisticated mechanisms to manipulate the physiology and behavior of their symbiotic animals. It is not implausible, therefore, that the ants’ fungi have evolved chemical and physiological schemes that alter ant behavior to serve the fungus’ reproductive interests, possibly even compromising the reproductive interests of the ant hosts.
The passage points out which of the following in order to explain the appeal of the notion that some attine ants cultivate and control fungus?
选项 A、The ants play the behaviorally active role in the symbiotic relationship.
B、The ants purposefully carry vegetation into their nests for their own consumption.
C、Fungus is physiologically a passive substance.
D、Other organisms are able to manipulate their symbiotic partners.
E、The chemical and physiological properties of the fungus are subject to ant influence.
答案A
解析 本题题干可以简单地理解成是什么因素导致人们认为是蚂蚁控制了真菌，所以首先定位点在前两句。appeal同义改写compelling，因此本题答案同义改写第二句，A正确。
