The official's conclusion is that people who claim that the U.S. is more vulnerable
than other nations because of the country's lack of a national vaccine laboratory
are disloyal and incorrect. His basis for that conclusion is that the U.S. has
generally long life span and low infant mortality relative to all UN countries.
Moreover, he cites the high quality of American hospitals, and he adds that many
people he knows from around the world come to the U.S. for medical care. We
are asked to find the choice that does NOT point out a weakness or potential
weakness in the official's argument.
(A) CORRECT. This choice states that the high quality of hospitals is not a factor
affecting the public's vulnerability to infectious disease. However, the quality of
hospitals very arguably does affect how vulnerable the public is to such disease.
(B) This choice highlights the official's logical jump from "disloyal" to "wrong" in
the phrase "these critics are disloyal and thus wrong about the public's
vulnerability." There is no necessary connection between disloyalty and
wrongness.
(C) If the Europeans that the official cited overwhelmingly consist of wealthy men
over the age of fifty, then the official relied on an unrepresentative sample to
justify his claim. What is true of wealthy older European men is not necessarily
true of Europeans or non-Americans generally.
(D) If the average life span of Americans is determined by causes other than
infectious disease, then the official is not limiting his evidence to cases relating to
vaccines. Other causes of death are not relevant to the critics' argument.
(E) The ranking of the United States relative to all UN countries is misleading,
since it does not compare the U.S. to other "advanced industrialized" or
"developed" nations, as the critics' claim does.
