Question ID:PT16 S3 Q1 Passage:The painted spider spins webs that are much stickier than the webs spun by the other species of spiders that share the same habitat. Stickier webs are more efficient at trapping insects that fly into them. Spiders prey on insects by trapping them in their webs; therefore, it can be concluded that the painted spider is a more successful predator than its competitors. Stem:Which one of the following, if true, most seriously weakens the argument? Correct Answer Choice:DChoice A:Not all of the species of insects living in the painted spider’s habitat are flying insects. Choice B:Butterflies and moths, which can shed scales, are especially unlikely to be trapped by spider webs that are not very sticky. Choice C:Although the painted spider’s venom does not kill insects quickly, it paralyzes them almost instantaneously. Choice D:Stickier webs reflect more light, and so are more visible to insects, than are less-sticky webs. Choice E:The webs spun by the painted spider are no larger than the webs spun by the other species of spiders in the same habitat.
