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 least80 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


Correct answer must be (D) for the highlighted errors in the other options..

D ans E were good for me.
E is something one can think after reading the passage. Nothing wrong as such with E but D is flawed relative to E.
D gives a perfect setup for why 80% would not know enough about medical concepts.

Answer D.
