2.Scientists propose placing seismic stations on the
fl oor of the Pacifi c Ocean to warn threatened coastal
communities on the northwestern coast of the United
States of approaching tidal waves caused by
earthquakes. Since forewarned communities could
take steps to evacuate, many of the injuries and
deaths that would otherwise occur could be avoided
if the government would implement this proposal.
The answer to which of the following questions
would be most important in determining whether
implementing the proposal would be likely to achieve
the desired result?
(A) When was the last time that the coastal
communities were threatened by an approaching
tidal wave?
(B) How far below sea level would the stations be
located?
(C) Would there be enough time after receiving
warning of an approaching tidal wave for
communities to evacuate safely?
(D) How soon after a tidal wave hits land is it safe
for evacuees to return to their communities?
(E) Can the stations be equipped to collect and
relay information about phenomena other than
tidal waves caused by earthquakes?

9.In order to reduce the number of items damaged while
in transit to customers, packaging consultants
recommended that the TrueSave mail-order company
increase the amount of packing material so as to fi ll
any empty spaces in its cartons. Accordingly,
TrueSave offi cials instructed the company’s packers
to use more packing material than before, and the
packers zealously acted on these instructions and
used as much as they could. Nevertheless, customer
reports of damaged items rose somewhat.
Which of the following, if true, most helps to explain
why acting on the consultants’ recommendation failed
to achieve its goal?
(A) The change in packing policy led to an increase
in expenditure on packing material and labor.
(B) When packing material is compressed too
densely, it loses some of its capacity to absorb
shock.
(C) The amount of packing material used in a carton
does not signifi cantly infl uence the ease with
which a customer can unpack the package.
(D) Most of the goods that TrueSave ships are
electronic products that are highly vulnerable to
being damaged in transit.
(E) TrueSave has lost some of its regular customers
as a result of the high number of damaged items
they received.

13In Swartkans territory, archaeologists discovered
charred bone fragments dating back one million years.
Analysis of the fragments, which came from a variety
of animals, showed that they had been heated to
temperatures no higher than those produced in
experimental campfires made from branches of white
stinkwood, the most common tree around Swartkans.
Which of the following, if true, would, together with the
information above, provide the best basis for the claim
that the charred bone fragments are evidence of the
use of fire by early hominids?
(A) The white stinkwood tree is used for building
material by the present-day inhabitants of
Swartkans.
(B) Forest fires can heat wood to a range of
temperatures that occur in campfires.
(C) The bone fragments were fitted together by the
archaeologists to form the complete skeletons
of several animals.
(D) Apart from the Swartkans discovery, there is
reliable evidence that early hominids used fire as
many as 500,000 years ago.
(E) The bone fragments were found in several
distinct layers of limestone that contained
primitive cutting tools known to have been used
by early hominids.
48If the county continues to collect residential trash at
current levels, landfills will soon be overflowing and
parkland will need to be used in order to create more
space. Charging each household a fee for each pound
of trash it puts out for collection will induce residents
to reduce the amount of trash they create; this charge
will therefore protect the remaining county parkland.
Which of the following is an assumption made in
drawing the conclusion above?
(A) Residents will reduce the amount of trash they
put out for collection by reducing the number of
products they buy.
(B) The collection fee will not significantly affect the
purchasing power of most residents, even if
their households do not reduce the amount of
trash they put out.
(C) The collection fee will not induce residents to
dump their trash in the parklands illegally.
(D) The beauty of county parkland is an important
issue for most of the county’s residents.
(E) Landfills outside the county’s borders could be
used as dumping sites for the county’s trash.
60Red blood cells in which the malarial-fever parasite
resides are eliminated from a person’s body after
120 days. Because the parasite cannot travel to a new
generation of red blood cells, any fever that develops
in a person more than 120 days after that person has
moved to a malaria-free region is not due to the
malarial parasite.
Which of the following, if true, most seriously weakens
the conclusion above?
(A) The fever caused by the malarial parasite may
resemble the fever caused by flu viruses.
(B) The anopheles mosquito, which is the principal
insect carrier of the malarial parasite, has been
eradicated in many parts of the world.
(C) Many malarial symptoms other than the fever,
which can be suppressed with antimalarial
medication, can reappear within 120 days after
the medication is discontinued.
(D) In some cases, the parasite that causes malarial
fever travels to cells of the spleen, which are
less frequently eliminated from a person’s body
than are red blood cells.
(E) In any region infested with malaria-carrying
mosquitoes, there are individuals who appear to
be immune to malaria.
64A prominent investor who holds a large stake in the
Burton Tool Company has recently claimed that the
company is mismanaged, citing as evidence the
company’s failure to slow production in response to a
recent rise in its inventory of fi nished products. It is
doubtful whether an investor’s sniping at management
can ever be anything other than counterproductive,
but in this case it is clearly not justifi ed. It is true
that an increased inventory of fi nished products often
indicates that production is outstripping demand, but
in Burton’s case it indicates no such thing. Rather, the
increase in inventory is entirely attributable to
products that have already been assigned to orders
received from customers.
In the argument given, the two boldfaced portions play
which of the following roles?
(A) The fi rst states the position that the argument
as a whole opposes; the second provides
evidence to undermine the support for the
position being opposed.
(B) The fi rst states the position that the argument
as a whole opposes; the second is evidence that
has been used to support the position being
opposed.
(C) The fi rst states the position that the argument
as a whole opposes; the second states the
conclusion of the argument as a whole.
(D) The fi rst is evidence that has been used to
support a position that the argument as a whole
opposes; the second provides information to
undermine the force of that evidence.
(E) The fi rst is evidence that has been used to
support a position that the argument as a whole
opposes; the second states the conclusion of
the argument as a whole.
