Spiders of many species change color to resemble the color of the flowers they sit on. Many animals that prey on such spiders possess color discrimination so acute that they, unlike human beings, can readily see the spiders despite the seeming camouflage. It is unlikely, therefore, that the spiders’ color changes confer significant survival benefit on these spiders.
Which of the following would it be most useful to determine in order to evaluate the argument?
选项
A、Whether the spiders’ own ability to discriminate color-camouflaged species is as acute as that of their predators
B、Whether the spiders have a color that could properly be regarded as their natural color
C、Whether the spiders’ color-changes allow them to remain undetected by prey
D、Whether different species of color-changing spiders tend to favor different species of flower
E、Whether the color-changing spiders prey on any insects that themselves change color
答案
C
解析
Yes:猎物识别不出蜘蛛→变色蜘蛛更容易吃到猎物→提升生存的可能性。削弱。No:猎物能识别变色蜘蛛→变色也不能让蜘蛛吃到更多的猎物+变色蜘蛛依然可以被捕食者发现→生存概率下降,加强。A项蜘蛛自己辨别颜色和蜘蛛的生存没关系。B项无关选项。D项无关选项。E项看不出变色对于蜘蛛的好处。
