4 According to life-insurance company
statistics, nine out of ten alcoholics
die before the age of seventy-five, as
opposed to seven out of ten
non-alcoholics A recent report issued by
the State Medical Board recounts
these statistics and concludes that
alcohol addiction increases a person’s
susceptibility to life-threatening
diseases, thereby reducing life
expectancy
The conclusion drawn by the State
Medical Board depends on which of
the following assumptions?
(A) People who are predisposed to
life-threatening diseases are
more likely than other people to
become alcoholic
(B) The statistics cited exclude
deaths due to other
alcohol-related events such as
automo-bile accidents
(C) Alcoholism does not also
increase a person’s
susceptibil-ity to diseases that are not
life-threatening
(D) The life expectancy of that
portion of the general
popula-tion not characterized by
alcoholism increases over time
(E) The author of the report is not
biased in his or her personal
opinion about the morality of
alcohol consumption
5 For the purpose of stimulating
innovation at TechCorp, one of the company’s long-standing goals has been to obtain at least 50 percent of its annual revenues from sales of products that are no more than three years old Last year, TechCorp achieved this goal, despite the fact that the company introduced no new products during the year
Which of the following, if true, best explains the results described above?
(A) None of the company’s competi-tors introduced any new
products during the last year
(B) Scientists at the company report that they are close to breakthroughs that should result in several new products during the coming year
(C) Sales of some of the company’s older products were discontin-ued during that last year
(D) The company has introduced
very few new products during the last three years
(E) Company spending on research and development has increased sharply over the past five years
QUESTIONS 6–8 ARE BASED ON THE FOLLOWING PASSAGE:
Line The Pan-American land bridge, or isthmus, connecting North and South America was formed volcanically long after dinosaurs became extinct The isthmus cleaved populations of marine organisms, creating sister species
These twin species, called “geminates,”
then evolved independently Scientists observe, for example, that Pacific pistol shrimp no longer mate with those from the Atlantic Ocean Yet the two oceans had already begun to form their distinctive personalities long before the isthmus was fully formed As the seabed rose, Pacific waters grew cooler, their upswelling currents carrying rich nutrients, while the Atlantic side grew shallower, warmer, and nutrient poor
In fact, it was these new conditions,

Trang 2and not so much the fully formed isthmus, that spawned changes in the shrimp population
For terrestrial life, the impact of the isthmus was more immediate Animals traversed the newly formed bridge in both directions, although North American creatures proved better colonizers—more than half of South America’s mammals trace direct lineage to this so-called Great Ameri-can Biotic Exchange Only three animals—the armadillo, opossum, and hedgehog—survive as transplants in the north today
6 Which of the following statements
finds the LEAST support in the passage?
(A) Population divergences result-ing from the formation of the Pan-American isthmus were more a process than an event
(B) The divergence in ocean temperature during the forma-tion of the Pan-American isthmus resulted in a diver-gence in the ocean’s nutrient value
(C) Genetic differences among pistol shrimp have grown to the point that there are now at least two distinct species of these shrimp
(D) The part of ocean that is now
the Pacific grew deeper due to the geologic forces that created the Pan-American isthmus
(E) Not until the Pan-American isthmus was fully formed did geminate marine organisms begin to develop in that area of the ocean
7 The author mentions the mating
habits of pistol shrimp in order to show that
(A) some species of marine organ-isms inhabiting the Pacific Ocean are now entirely distinct from those in the Atlantic Ocean
(B) twin species of marine organ-isms can each survive even though one species can no longer mate with the other
(C) since the formation of the Pan-American isthmus, some marine geminates no longer mate with their sister species
(D) geminate species that do not
mate with one another are considered separate species
(E) the evolutionary impact of the Pan-American isthmus was greater for marine organisms than for land animals
8 Which of the following statements is
most readily inferable from the information in the passage?
(A) Species of marine organisms in the Atlantic Ocean number fewer today than before the formation of the Pan-American isthmus
(B) The number of terrestrial animal species in South America today exceeds the number prior to the formation
of the Pan-American isthmus
(C) Of the indigenous North American species that migrated south across the Pan-American isthmus, more than three survive to this day
(D) Since the formation of the
Pan-American isthmus, fewer terrestrial animals have traveled north across the isthmus than south
(E) As the Pan-American isthmus began to form, most pistol shrimp migrated west to what
is now the Pacific Ocean

QUESTIONS 15–17 ARE BASED ON THE FOLLOWING PASSAGE:
Line Historians sometimes forget that no matter how well they might come to know a particular historical figure, they are not free to claim a godlike knowledge of the figure or of the events surrounding the figure’s life Richard III, one of England’s monarchs, is an apt case because we all think we
“know” what he was like In his play
Richard III, Shakespeare provided a
in both body and soul Shakespeare’s great artistry and vivid depiction of Richard has made us accept this creature for the man We are prepared, therefore, to interpret all the events around him in such a way as to justify our opinion of him
We accept that Richard executed his brother Clarence, even though the records of the time show that Richard pleaded for his brother’s life We assume that Richard supervised the death of King Henry VI, overlooking that there is no proof that Henry was actually murdered And we recoil at Richard’s murdering his two nephews, children of his brother’s wife Elizabeth; yet we forget that Elizabeth had spent her time on the throne plotting to replace her husband’s family in power with her own family Once we appreci-ate the historical context, especially the actions of Richard’s opponents, we
no longer see his actions as monstrous Richard becomes, if not lovable, at least understandable What’s more, when we account for the tone of the times during which Richard lived, as illuminated in literary works of that
era such as Machiavelli’s The Prince,
Richard’s actions seem to us all the more reasonable
15 With which of the following
state-ments would the author of the passage most likely agree?
(A) In Richard III, Shakespeare
portrays the king as more noble than he actually was
(B) The deeds of Elizabeth were even more evil than those of Richard III
(C) Richard III may have been innocent of some of the crimes that Shakespeare leads us to believe he committed
(D) Richard III may have had a
justifiable reason for killing Henry VI
(E) Shakespeare was unaware of many of the historical facts about the life of Richard III

Trang 516 The author of the passage refers to
Shakespeare’s “great artistry and
vivid depiction of Richard” (lines
12–14) most probably in order to
(A) make the point that studying
Richard III is the best way to
understand Richard as a
historical figure
(B) explain why Richard III is
widely acclaimed as one of
Shakespeare’s greatest works
(C) contrast Shakespeare’s
depic-tion of Richard with how
Richard might have described
himself
(D) illustrate how historians might
become prejudiced in their view
of historical figures
(E) point out that historians should
never rely on fictional works to
understand and interpret
historical events
17 It can be inferred from the passage
information that Machiavelli’s The
Prince helps show
(A) that, in his play Richard III,
Shakespeare’s depiction of the
king was historically accurate
(B) that Richard’s actions were an
accurate reflection of the times
in which he lived
(C) that different authors often
depict the same historical
figures in very different ways
(D) that Machiavelli was more
astute than Shakespeare as an
observer of human nature
(E) that Richard’s actions as a king
are not surprising in light of his
earlier actions as a prince
18 PharmaCorp, which manufactures
the drug Aidistan, claims that Aidistan is more effective than the drug Betatol in treating Puma Syndrome To support its claim, PharmaCorp cites the fact that one of every two victims of Puma Syndrome
is treated successfully with Aidistan alone, as opposed to one out of every three treated with Betatol alone
However, PharmaCorp’s claim cannot
be taken seriously in light of the fact that the presence of Gregg’s Syn-drome has been known to render Puma Syndrome more resistant to any treatment
Which of the following, if true, would most support the allegation that PharmaCorp’s claim cannot be taken seriously?
(A) Among people who suffer from both Puma Syndrome and Gregg’s Syndrome, fewer are treated with Aidistan than with Betatol
(B) Among people who suffer from both Puma Syndrome and Gregg’s Syndrome, fewer are treated with Betatol than with Aidistan
(C) Gregg’s Syndrome reduces Aidistan’s effectiveness in treating Puma Syndrome more than Betatol’s effectiveness in treating the same syndrome
(D) Betatol is less effective than
Aidistan in treating Gregg’s Syndrome
(E) Neither Aidistan nor Betatol is effective in treating Gregg’s Syndrome

20 Which of the following provides the
most logical completion of the passage below?
More and more consumers are being attracted to sport utility vehicles because they are safer to drive than regular cars and because of the feeling of power a person experiences when driving a sport utility vehicle
In its current advertising campaign, Jupiter Auto Company emphasizes the low price of its new sport utility vehicle compared to the price of other such vehicles However, this market-ing strategy is unwise because
(A) Jupiter’s sport utility vehicle is not as safe as those produced by competing automobile manufac-turers

21 Since City X reduced the frequency
with which its service vehicles pick up
recyclable materials from residences
for transport to its recycling center,

seems most appropriate for City X in
the interest of reducing the volume of
material that the city’s service
vehicles transport to landfills?

25 No nation in the world has
experi-enced as significant a decline in its Yucaipa tree population as our nation
Yet only our nation imposes a law pro-hibiting the use of Yucaipa tree-bark oil in cosmetics The purpose of this law in the first place was to help maintain the Yucaipa tree population,
at least in this nation But the law is clearly unnecessary and therefore should be repealed
Which of the following, if true, would most seriously weaken the conclusion drawn in the passage?
(A) This nation contains more Yucaipa trees than any other nation
(B) Yucaipa tree-bark oil is not used for any consumer goods other than cosmetics
(C) The demand for cosmetics containing Yucaipa tree-bark oil
is expected to decline in the future in other nations while continuing unabated in this nation
(D) In other countries, labor used to
harvest Yucaipa trees for cosmetics is less expensive than comparable labor in this nation

QUESTIONS 28–30 ARE BASED ON THE
FOLLOWING PASSAGE:
Line Diseases associated with aging in
women are difficult to correlate
explicitly with estrogen deficiency
because aging and genetics are
impor-tant influences in the development of
such diseases A number of studies,
however, indicate a profound effect of
estrogen deficiency in syndromes such
as cardiovascular disease (including
atherosclerosis and stroke) and
os-teoporosis—the loss and increasing
fragility of bone in aging individuals
The amount of bone in the elderly
skeleton—a key determinant in its
susceptibility to fractures—is believed
to be a function of two major factors
The first is the peak amount of bone
mass attained, determined to a large
extent by genetic inheritance The
marked effect of gender is obvious—
elderly men experience only one-half as
many hip fractures per capita as
elderly women However, African
American women have a lower
inci-dence of osteoporotic fractures than
Caucasian women Other important
variables include diet, exposure to
sunlight, and physical activity The
second major factor is the rate of bone
loss after peak bone mass has been
attained While many of the variables
that affect peak bone mass also affect
rates of bone loss, additional factors
influencing bone loss include
physi-ological stresses such as pregnancy and
lactation It is hormonal status,
however, reflected primarily by
estro-gen and progesterone levels, that may
exert the greatest effect on rates of
decline in skeletal mass
28 Based upon the passage, which of the
following is LEAST clearly a factor affecting the rate of decline in bone mass?
(A) Gender
(B) Exposure to sunlight
(C) Progesterone levels
(D) Age (E) Estrogen levels
29 In discussing the “marked effect of
gender” (line 20), the author assumes all of the following EXCEPT
(A) the difference in incidence of hip fractures is not due instead
to different rates of bone loss
(B) the incidence of hip fractures among elderly men as compared
to elderly women is representa-tive of the total number of bone fractures among elderly men as compared to elderly women
(C) elderly women are not more accident-prone than elderly men
(D) the population upon which the
cited statistic is based includes both African Americans and Caucasians
(E) men achieve peak bone mass at the same age as women
30 It can be inferred from the passage
that the peak amount of bone mass
in women
(A) is not affected by either preg-nancy or lactation
(B) is determined primarily by diet
(C) depends partly upon hormonal status
(D) may play a role in determining
the rate of decrease in estrogen and progesterone levels
(E) is not dependent upon genetic makeup

Trang 1031 Vining University’s teacher
creden-tial program should be credited for the high grade-point averages of high school students who enroll in classes taught by Vining graduates More new graduates of Vining’s credential program accept entry-level positions
at Franklin High School than at any other high school And during the most recent academic year, just prior
to which many of Franklin’s teachers transferred to Valley View High School, the median grade point average of the students at Franklin has declined while at Valley View it has increased
The argument above depends on which of the following assumptions?
(A) The two high schools employ different methods of computing student grade point averages
(B) Neither high school has a peer tutoring program that would afford the school an advantage over the other in terms of student academic performance
(C) Just prior to last year, more teachers transferred from Franklin to Valley View than from Valley View to Franklin
(D) The teachers who transferred
from Franklin to Valley View were replaced with teachers who are also graduates of Vining University’s teacher credential program
(E) The teachers who transferred from Franklin to Valley View last year were graduates of Vining’s teacher credential program
32 More airplane accidents are caused
by pilot error than any other single factor The military recently stopped requiring its pilots to obtain immuni-zation shots against chemical
warfare agents These shots are known to cause unpredictable dizzy spells, which can result in pilot error Since many military pilots also pilot commercial passenger airliners, the reason for the military’s decision must have been to reduce the number of commercial airline accidents
Which of the following, if true, provides most support for the conclusion drawn above?
(A) Recently, more pilots have been volunteering for the immuniza-tion shots
(B) All commercial airline flights are piloted by two co-pilots, whereas military flights are usually piloted by only one
(C) Chemical warfare is likely to escalate in the future
(D) Military pilots are choosing to
resign rather than obtain the immunization shots
(E) Recently, the number of mili-tary pilots also piloting commer-cial airliners has declined
