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

(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.

但是狒狒上解释是

A是支持作者观点

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！

我觉得A和D没什么差别，除了多了那一段，为什么A就是支持，B就是以偏概全呢，哪位牛牛能帮忙解释下，谢谢

自己up...请牛牛解答

仅解释A中一点： ”news stories about DNA“ 所以与原文无关

可是答案里解释A是支持，好奇怪的说

我的想法：

原文试图knows enough about DNA=medical concepts to make well-informed personal medical choices or to make good public policy decisions about health care.
