想请问各位大大， 小弟我在做CR题目的时候， 最头痛的就是碰到段落中套句粗体字的题目， 然後问这两句扮演的角色是什麽。 因为这类的题目几乎每答必错， 请问有什麽方法可循吗? 可以的话请以以下这段话解释一下，感恩! 32. Paleontologist: About 2.8 million years ago, many species that lived near the ocean floor suffered substantial population declines. These declines coincided with the onset of an ice age. The notion that cold killed those bottom-dwelling creatures outright is misguided, however; temperatures near the ocean floor would have changed very little. Nevertheless, the cold probably did cause the population declines, though indirectly. Many bottom-dwellers depended for food on plankton, small organisms that lived close to the surface and sank to the bottom when they died. Most probably, the plankton suffered a severe population decline as a result of sharply lower temperatures at the surface, depriving many bottom-dwellers of food. In the paleontologist's reasoning, the two portions in boldface play which of the following roles? (A) The first introduces the hypothesis proposed by the paleontologist; the second is a judgment offered in spelling out that hypothesis. (B) The first introduces the hypothesis proposed by the paleontologist; the second is a position that the paleontologist opposes. (C) The first is an explanation challenged by the paleontologist; the second is an explanation proposed by the paleontologist. (D) The first is a judgment advanced in support of a conclusion reached by the paleontologist; the second is that conclusion. (E) The first is a generalization put forward by the paleontologist; the second presents certain exceptional cases in which that generalization does not hold. --
