Question ID:PT74 S1 Q4 Passage:Scientist: Rattlesnakes prey on young California ground squirrels. Protective adult squirrels harass a threatening rattlesnake by puffing up their tails and wagging them. New results show that the squirrel's tail also heats up when harassing a rattlesnake. Since rattlesnakes have an infrared sensing organ that detects body heat, the heating up of the squirrel's tail probably plays a role in repelling rattlesnakes. Stem:Which one of the following, if true, most helps to support the scientist's hypothesis?  Correct Answer Choice:CChoice A:Rattlesnakes do not have the ability to increase the temperature of their tails. Choice B:Squirrels puff up their tails and wag them when they attempt to attract the attention of other squirrels. Choice C:Rattlesnakes react much more defensively when confronted with a squirrel whose tail is heated up than when confronted with one whose tail is not.  Choice D:The rattlesnake is not the only predator of the California ground squirrel that causes it to engage in harassing behavior as a defensive mechanism. Choice E:Mammals such as the California ground squirrel have no organ for sensing infrared energy.
