Although 90 percent of the population believes itself to be well informed about health care, only 20 percent knows enough about DNA to understand a news story 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: one's being able to make well-informed personal medical choices ensures that one makes good public policy decisions about health care
B: 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
C: 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
D: an understanding of DNA is essential to making well-informed personal medical choices or to making good public policy decisions about health care
