1. Although 90 percent of the population believes itself to be well informed about health care, only 20 percent knows enough about DNA. So apparently at least 80 percent of the population does not know enough about medical concepts to make well-informed personal medical choices or to make good public policy decisions about health care.
The argument’s reasoning is questionable because the argument fails to demonstrate that
A.    those people who can understand news stories about DNA are able to make well-informed personal medical choices
B.    more than 20 percent of the population needs to be well informed about health care for good public policy decisions about health care to be made
C.    one’s being able to make well-informed personal medical choices ensures that one makes good public policy decisions about health care
D.    an understanding of DNA is essential to making well-informed personal medical choices or to making good public policy decisions about health care
E.    since 90 percent of the population believes itself to be well informed about health care, at least 70 percent of the population is mistaken in that belief.
答案：D
思路：本题的推论错误在于以偏概全，用对DNA的了解程度来考核well informed about health care的程度。据个例子，我们可否用掌握核物理知识的程度来考核对物理基本知识的掌握程度呢？显然不行！
A: 支持作者的观点
B: 无关
C: 无关
D: 本题的推论错误在于以偏概全，用对DNA的了解程度来考核well informed about health care的程度。据个例子，我们可否用掌握核物理知识的程度来考核对物理基本知识的掌握程度呢？显然不行！
E: 无关

问题中不是有个 fail to demonstrate 的吗

dota少年，读题要仔细The argument’s reasoning is questionable because the argument fails to demonstrate that
翻译是：这个argument的推理是有问题的，因为argument没有描述XX

说白了就是个assumption题，加上D这个推理就成立了。
