1. Armtech, a temporary-employment agency, previously
gave its employees 2.5 paid vacation days after each
700 hours worked. Armtech’s new policy is to give
its employees 5.0 paid vacation days after each 1,200
hours worked. Therefore, this new policy is more
generous to Armtech employees in giving them more
vacation days per hour worked than the old policy did.
Which of the following is an assumption on which
the argument depends?
(A) Most current Armtech employees approve of the
company’s new vacation policy.
(B) A few Armtech employees leave the company
before having worked 700 hours.
(C) Most Armtech employees were not aware that
the company planned to change its vacation
policy until after it had already done so.
(D) A significant portion of Armtech employees stay
with the company long enough to work for
1,200 hours.
(E) Armtech’s new vacation policy closely matches
the vacation policies of competing temporary
employment agencies.
2 The global population of frogs has declined in recent
years while the amount of ultraviolet radiation reaching
the Earth has increased. Since the genetic material in
frog eggs is harmed when exposed to ultraviolet radi-
ation, and since the eggs themselves are not protected
by shells or leathery coverings but are gelatinous, the
frog population decline is probably due, at least in
part, to the ultraviolet radiation increase.
Which of the following, if true, provides the strongest
support for the argument?
(A) Even in those regions where there has been no
significant increase in ultraviolet radiation, only
a small proportion of the frog eggs that are laid
ever hatch.
(B) In areas where there has been the least decline
in frog populations, populations of species of
insects that frogs eat have decreased.
(C) The eggs of frog species whose populations are
declining tend to have higher concentrations of
damaging pesticides than do the eggs of frog
species whose populations have not declined.
(D) In many places where turtles, which lay eggs
with tough, leathery coverings, share habitats
with frogs, turtle populations are also in decline.
(E) Populations of frog species that hide their eggs
beneath rocks or under sand have declined
considerably less than have populations of frog
species that do not cover their eggs.
Questions 3-8

Questions 9-10 are based on the following graph.
In January of 1990 a certain country enacted a strict new law to deter people from drunken driving. The law imposes
mandatory jail sentences for anyone convicted of drunken driving.
9.Which of the following, if true about the years 1990
through 1992, most helps to explain the data illus-
trated in the graph?
(A) Most of the people arrested for and convicted of
drunken driving were repeat offenders.
(B) Many of the people arrested for and convicted of
drunken driving participated in alcohol-education
programs in order to reduce their jail sentences.
(C) Juries in drunken driving cases became increas-
ingly reluctant to convict people on whom
mandatory jail sentences would be imposed.
(D) Since the law was enacted, the number of deaths
attributed to drunken driving has declined
significantly.
(E) The majority of the residents of the country
supported the strict law to deter people from
drunken driving.
10.Which of the following, if true, strengthens the claim
that the changes in the ratio of arrests to convictions
since the beginning of 1990 are due to an increase in
the number of people arrested for drunken driving
who were not drunk?
(A) Before 1990 only people driving erratically were
stopped by the police on suspicion of drunken
driving, but since the beginning of 1990 police
have been allowed to stop drivers randomly
and to arrest any driver whom they suspect of
having drunk any alcohol.
(B) Since the beginning of 1990 new technology has
enabled police who stop a driver to establish
immediately whether the driver is drunk,
whereas before 1990 police had to rely on
observations of a driver’s behavior to make a
judgment about that driver’s drunkenness.
(C) After 1990 the number of police officers assigned
to patrol for drunken drivers increased only
very slightly compared to the number of police
officers assigned to patrol for drunken drivers
in the years 1985 through 1989.
(D) In 1990 a greater number of drivers were igno-
rant of the laws concerning drunken driving
than were ignorant of the drunken driving laws
in 1989.

a greater proportion of those arrested for drunken
driving than in the years 1985 through 1989.
11 To improve productivity, manufacturing companies
have recently begun restructuring work to produce
more goods with fewer assembly-line workers, and
the companies have laid off many workers as a
consequence. The workers laid off have been those
with the least seniority(time on the job), generally
the younger workers.
The statements above, if true, most strongly support
which of the following as a conclusion?
(A) The products manufactured by the companies are
not undergoing design changes while the
manufacturing jobs are being restructured.
(B) When assembly-line workers have made sug-
gestions for improvements in manufacturing
processes, some suggestions have been
implemented, but many have not.
(C) Assembly-line workers now need increased
reading and mathematical skills to do their
jobs.
(D) Some of the innovations in assembly-line
processes and procedures that were made to
increase productivity have instead proved to be
counterproductive.
(E) The manufacturing companies are increasing the
average age of their assembly-line workforce
while still seeking to increase production.
12.During the nineteenth century, Britain’s urban popu-
lation increased as its rural population diminished. A
historian theorizes that, rather than industrialization’s
being the cause, this change resulted from a series
of migrations to urban areas, each occasioned by a
depression in the agrarian economy. To test this hypoth-
esis, the historian will compare economic data with
population census data.
The historian’s hypothesis would be most strongly
supported if which of the following were found to be
true?
(A) The periods of greatest growth in the industrial
economy were associated with a relatively
rapid decline in the rural population.
(B) The periods of greatest weakness in the agrarian
economy were associated with relatively slow
growth in the population as a whole.
(C) Periods when the agrarian economy was compar-
atively strong and the industrial economy com-
paratively weak were associated with a particu-
larly rapid decline in the rural population.
(D) Periods when the agrarian and industrial econo-
mies were both strong were associated with
particularly rapid growth in the urban popula-
tion.
(E) The periods of greatest strength in the agrarian
economy were associated with relatively slow
growth in the urban population.

23 Politician：Each year, small businesses create more
jobs than do large established businesses.
Therefore, in order to reduce unemploy-
ment in the long term, we should provide
incentives for starting small businesses
rather than for expanding established large
businesses.
Which of the following, if true, casts the most doubt
on the politician’s argument?
(A) In general, people employed by small businesses
report higher job satisfaction than do people
employed by large businesses.
(B) Among the currently unemployed are many
people with sufficient job skills to perform the
jobs that small businesses would create.
(C) Providing an effective incentive for starting a
business generally costs significantly less than
providing an effective incentive for expanding
a large business.
(D) A high proportion of small businesses fail within
three years of starting because of their owners’
inexperience.
(E) The average large business contributes more
money to politicians’ campaign funds than the
average small business does.
24 In the workplace, influenza is typically spread by
infected individuals to others with whom they work
in close quarters. A new medication that suppresses
the symptoms of influenza therefore will actually
increase the number of influenza cases, because this
medication will allow people who would otherwise be
home in bed to return to work while infected.
Which of the following, if true, most seriously chal-
lenges the prediction?
(A) Coughing, a symptom of influenza that the new
medication suppresses, is a primary mechanism
in the spread of this illness.
(B) Some medications that are used to suppress
symptoms of influenza are also used by many
people to treat symptoms that are caused not
by influenza but by other illnesses.
(C) Many workers who now remain at home when
infected with influenza do so because the
symptoms of influenza prevent them from per-
forming their jobs effectively.
(D) Most adults who are immunized against influ-
enza in order to avoid being infected are over
65 years old and retired and thus do not work
outside the home.
(E) Symptoms of an illness are often the body’s
means of curing itself of the illness, and there-
fore suppression of symptoms can prolong the
illness that causes them.
25 Editorial：
Critics of nuclear power complain about the allegedly
serious harm that might result from continued operation
of existing nuclear power plants. But such concerns do
not justify closing these plants;after all, their operation
has caused no more harm than that caused by pollution
generated by coal-and oil-burning power plants, the
most important other sources of energy.
Which of the following is an assumption on which the
argument depends?
(A) Existing nuclear power plants should be closed only
if it can be conclusively demonstrated that their
continued operation is likely to cause harm more
serious than the harm their operation has already
caused.
(B) Closing existing nuclear power plants would require
greatly increased reliance on coal-and oil-burning
power plants.
(C) The harm that has resulted from operation of
existing coal-and oil-burning power plants has
been significant.
(D) The harm that a nuclear power plant is likely to
cause as it continues to operate can be reliably
predicted from the past history of nuclear power
plants.
(E) The only harm that has resulted from operation of
existing coal-and oil-burning power plants has
resulted from the pollution generated by these
plants.
