Test 1
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.
2. During the 1980’s, Japanese collectors were very active in the market for European art, especially as purchasers of nineteenth-century Impressionist paintings. This striking pattern surely reflects a specific preference on the part of many Japanese collectors for certain aesthetic attributes they found in nineteenth-century Impressionist paintings.
Which one of the following, if true, most strongly supports the explanation above?
(A) Impressionist paintings first became popular among art collectors in Europe at the beginning of the twentieth century.
