问题     In the 1920s, Gerstmann described a set of problems found in people who have suffered damage to the brain’s left parietal lobe, problems that include being unable to understand arithmetic and having difficulty identifying one’s fingers. There is still no agreement on whether the symptoms Gerstmann noticed constitute a syndrome, but the parts of the brain used for storing facts about numbers and for representing the fingers are close to each other. Mental representations of numbers and of fingers may therefore be functionally connected. A 2005 experiment had people perform some tasks requiring dexterity and others involving matching pairs of numbers, while an area of their parietal lobes—the left angular gyrus—was stimulated by a magnetic field. Facility at both sets of tasks was impaired.
The author of the passage describes the “2005 experiment” and its results primarily in order to
选项 A、establish the proximity between the part of the brain used for storing numerical information and the part used for representing the fingers
B、illustrate the implications that Gerstmann’s work may have for experimental research
C、cast doubt on the idea that damage to the left parietal lobe causes the set of problems that Gerstmann described
D、support a hypothesis about a significant association between parts of the brain related to fingers and to numbers
E、suggest that the problems Gerstmann noted in relation to numbers and fingers have a different cause than the other problems associated with parietal lobe damage
答案D
解析 本题容易混淆选项A和选项D。两个部位靠得很近在这篇文章里其实是不需要被支持的，因为根据第二句，前半句说这些症状是否是综合征“还没达成共识”，因此后半句两个部位靠得近应该是达成了共识的。既然作者认为达成了共识，便不需要支持。需要支持的是后一句作者的结论：两个功能是相关的，因此选项D正确。
