Question ID:PT15 S3 Q8 Passage:Delta green ground beetles sometimes remain motionless for hours at a stretch, although they are more active in wet years than in dry years. In 1989 an observer spotted ten delta green ground beetles in nine hours; in 1985 the same observer at the same location had counted 38 in about two hours. This difference probably does not reflect a drop in the population of these rare beetles over this period, however, because 1985 was a wet year and 1989 was relatively dry. Stem:Which one of the following, if true, most strongly supports the conclusion drawn above? Correct Answer Choice:AChoice A:Because of their excellent camouflage, delta green ground beetles are almost impossible to see if they are not moving. Choice B:The only habitat of delta green ground beetles is around pools formed by the collection of winter rains in low-lying areas. Choice C:Delta green ground beetles move about very little to get food; most of their moving from one place to another is related to their reproductive behavior. Choice D:Delta green ground beetles are so rare that, although the first specimen was found in 1878, a second was not found until 1974. Choice E:No predator relies on the delta green ground beetle for a major portion of its food supply.
