It is more desirable to have some form of socialized medicine than a system of medical care relying on the private sector. Socialized medicine is more broadly accessible than is private-sector system. In addition, since countries with socialized medicine have a lower infant morality rate than do countries with a system relying entirely on the private sector, socialized medicine seems to be technologically superior.
Which one of the following best indicates a flaw in the argument about the technological superiority of socialized medicine?
(A) The lower infant mortality rate might be due to the systems allowing greater access to medical care.
(B) There is no necessary connection between the economic system of socialism and technological achievement.
(C) Infant mortality is a reliable indicator of the quality of medical care for children.
(D) No list is presented of the countries whose infant mortality statistics are summarized under the two categories, “socialized” and “private-sector.”
(E) The argument presupposes the desirability of socialized medicine, which is what the argument seeks to establish.
