25 Questions
1. Drug companies lose money when manufacturing
drugs that cure those suffering from rare diseases
because selling a drug to only a few people usually
does not recoup manufacturing expenses．Therefore,
a company manufacturing any of the drugs that cure
those suffering from loxemia, an extremely rare
disease, will undoubtedly lose money．
Which of the following, if true, most seriously
weakens the conclusion above？
(A)Several drugs that cure those suffering from
loxemia also cure those suffering from very
common illnesses．
(B)Most of those who contract loxemia also con-
tract another illness concurrently．
(C)Most of the drug companies that manufacture
drugs that cure rare diseases do not manufac-
ture drugs that cure loxemia．
(D)A sizable number of people are afflicted with
one or another rare disease even though each
rare disease afflicts only a small number of
people．
(E)The larger the amount of a drug that is manu-
factured, the lower the manufacturing expense
for each unit of the drug that is produced．
2.The tomb of a warrior killed in 1501 bears a sculpted
portrait depicting him dressed for battle．Some his-
torians attribute the portrait to an artist from that
century, but of the many references to the tomb in
surviving documents, none that predates the 1800’s
mentions the portrait．The portrait is therefore more
likely the work of a much later artist．
Which of the following, if true, would also support
the conclusion of the argument if substituted for the
evidence given concerning the portrait？
(A)The portrait of the warrior was commissioned by
the family of the warrior’s widow．
(B)References in surviving documents mention that
an artist was paid in 1525 for an unspecified
number of works for the church in which the
tomb is located
(C)The warrior is depicted in the portrait as wearing
boots made of a material not used for boots
until the 1700’s．
(D)Some other art treasures from the church in
which the tomb is located have been reliable
dated to the 1400’s．
(E)The portrait of the warrior on the tomb strongly
resembles a portrait of him known to have
been completed during his lifetime．
