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.
Questions 3-7 A florist is
designing flower arrangements
containing two or more varieties
of flowers selected from among
six varieties of flowers:freesias,
irises, lilies, peonies, tulips,and
zinnias.All acceptable arrangements
conform to the following conditions:If
an arrangement contains any
freesias, it cannot contain
any zinnias. If an arrangement
contains any tulips, it cannot
contain any zinnias. If an arrangement
contains any peonies, it must
also contain at least one zinnia,
and there must be exactly as
many zinnias as peonies. If
an arrangement contains any
irises, it must also contain
tulips, and there must be twice
as many tulips as irises. If
an arrangement contains freesias,
the number of freesias must
be greater than the total number
of other flowers used.

8.Scientist:More than 1, 000
large asteroids regularly cross
the Earth‘s path.Even though
the probabil- ity of one colliding
with the Earth is extremely
slight, we should do whatever
we can to reduce that probability
since any such collision would
be catastrophic.The best way
to avoid such a disaster is
to deflect the asteroids.The
only known way of deflecting
asteroids is by hitting them
with nuclear weapons that would
be stored in space stations.
The scientist‘s claims are
structured so as to lead to
which of the following conclusions?
(A)Nuclear technology is the
only technology that can plausibly
be used to prevent natural catastrophes.
(B)Nuclear weapons should
be deployed in space.
(C)No catastrophe has yet
been caused by the collision
of an asteroid with the Earth.
(D)The 1, 000 large asteroids
that cross the Earth‘s path
pose only an extremely slight
risk of colliding with the Earth.
(E)There is currently no acceptable
use to which nuclear weapons
can be put, aside from pro-
tecting the Earth from asteroids.
9.It has long been thought
that high levels of the hor-
mone testosterone contribute
to the onset of heart disease
in men.However, this view cannot
be correct,since men who have
heart disease typically show
significantly lower levels of
testosterone than do men who
have not had heart disease.
The argument above assumes
which of the following?
(A)Many men who have never
had heart disease have unusually
low levels of testosterone.
(B)Having heart disease does
not significantly lower the
level of testosterone in men.
(C)Levels of hormones other
than testosterone significantly
affect the likelihood that a
man will develop heart disease.
(D)Heart disease and lowered
testosterone levels in men are
the effects of a single common
cause.
(E)High levels of testosterone
have never been thought to contribute
to a serious disease other than
heart disease 10.The time-out
technique involves removing
the child from an undesirable
situation in order to let the
child think things over.Over
the last two decades, family
doctors have been advocating
this technique as preferable
to spanking, which is now known
to be potentially injurious
and no more effective.
10.Which of the following
can properly be concluded from
the data presented in the graph?
(A)The 1962 survey was based
on a larger sample than the
1992 survey was.
(B)In the period between the
surveys, denying tele- vision
privileges was never the disciplinary
technique most popular with
parents.
(C)The four disciplinary techniques
featured in the graph were the
only disciplinary techniques
named by parents in either survey.
(D)The 1962 survey allowed
parents to name more than one
disciplinary technique, but
the 1992 survey may not have
allowed this.
(E)In the period between the
surveys, there were no significant
changes in the popularity of
lec- turing children as a disciplinary
method.
11.People who engage in scuba
diving are healthier, on average,
than people who do not engage
in this activity.Therefore,
scuba diving tends to promote
improved health.
The argument is most vulnerable
to criticism on the grounds
that it
(A)presupposes that everyone
who takes up scuba diving does
so solely for health reasons
(B)leads to a further and
falsifiable conclusion that
no one can achieve good health
without engaging in scuba diving
(C)fails to point out that
a small number of people are
seriously injured in scuba diving
accidents each year
(D)treats a precondition for
improving one‘s health as though
it were something that by itself
could ensure good health
(E)overlooks the possibility
that people generally do not
take up scuba diving unless
they are in good health Questions

23.Which of the following
most logically completes the
argument below?
In recent years, the proportion
of car buyers who buy new cars
rather than used cars has declined.Some
consumers have attributed this
change to an increase in new-car
prices.As evidence of the price
increase,they cite figures that
show that, even adjusting for
inflation, the price that the
buyer of a new car pays,on average,
is far higher now than a few
years ago. This evidence is
unpersuasive, however, because
(A)the value of a car that
is bought new declines much
more rapidly than does the value
of a car that is bought used
(B)after someone has bought
a car, it might be several years
before that person next buys
a car
(C)a decline in the proportion
of car buyers who buy new cars
must necessarily mean that the
proportion who buy used cars
has increased
(D)the relative increase in
used-car sales might be explained
by the decisions of only a small
proportion of all car buyers
(E)the change in the average
price paid for a new car could
result solely from more people‘s
rejecting inexpensive new cars
in favor of used cars
24.In Bassaria a group of
that country‘s most senior judges
has criticized the uniform mandatory
sentences recently introduced
for certain specific crimes.The
judges argue that such sentences,
by depriving them of all discretion
in setting sentences, make it
impos- sible for them to consider
either aggravating or exten-
uating circumstances and so
make it impossible to achieve
true justice―the fitting of
the severity of the punishment
to the gravity of the particular
crime. Which of the following,
if true, provides the strongest
evidence for the claim that
in Bassaria the newly introduced
mandatory sentences are not
necessarily a change for the
worse with respect to achieving
true justice as defined in the
argument?
(A)Before mandatory sentencing,
judges in eastern Bassaria imposed
strikingly different sentences
from those in western Bassaria
for equally grave instances
of the same kind of offense.
(B)In Bassaria the frequency
of crimes that have been made
subject to mandatory sentences
is lower now than it was just
prior to the intro- duction
of mandatory sentencing.
(C)The law introducing mandatory
sentences was passed in the
legislature of Bassaria by a
large majority and is unlikely
to be repealed in the foreseeable
future.
(D)There used to be a wide
difference between the minimum
and the maximum sentences allowed
by law in cases of crimes now
subject to man- datory sentences.
(E)In Bassaria judges are
appointed for life and are thus
not easily influenced by political
pressure groups.
25.Each of two particular
inspection systems that are
based on different principles
would detect all product flaws
but would also erroneously reject
three percent of flawless products.Assuming
there is no overlap between
the products erroneously rejected
by the two systems and also
no interference between the
systems if both operate,using
both systems and rejecting only
those products found flawed
by both would be a way of avoiding
all erroneous rejections.
Which of the following most
precisely characterizes the
reasoning in the argument?
(A)The reasoning is conclusive,
that is, the conclusion cannot
be false if the statements offered
in its support are true.
(B)The reasoning is strong
but not conclusive, if the statements
offered in support of the conclusion
are true, they provide good
grounds for that conclu- sion,
though it is possible that additional
infor- mation might weaken the
argument.
(C)The reasoning is weak;
the statements offered in support
of the conclusion, though relevant
to it,by themselves provide
at best inadequate grounds for
the conclusion.
(D)The reasoning is flawed
in that the conclusion is no
more than a paraphrase of one
of the pieces of evidence offered
in its support.
(E)The reasoning is flawed
in that the argument treats
evidence that a factor is necessary
to bring about an event as if
it were evidence that the factor
is sufficient to bring about
that event.……
