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 demonstratethat


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.
个人觉得如果题目改成,The argument’s reasoning is questionable because the argument demonstrates that
这样子答案才会是D啊。。。

这道题错误的在于默认了an understanding of DNA is essential to making well-informed personal medical choices or to making good public policy decisions about health care ,把他当成推理的assumption,然而这个条件大家都不能确定是正确的。
问题问的是这个reasoning is questionable是为什么,那么就是没有能告诉大家其实这个条件是正确的。

当时选的答案是A
如果问题改成which of the following undermines the argument的话,倒是有可能
大家觉得呢
我现在的理解对不对啊
