Passage I (Questions 1-7)
In the course of the twentieth century, increasing
awareness of how chemical wastes can affect public health
and the environment resulted in restriction of dumping
However, where dumping had already occurred,
uncontrolled or abandoned hazardous wastes remained at
5
sites such as warehouses, landfills, and even rivers To
locate, investigate, and clean up the worst of these sites
nationwide, Congress in 1980 established the Superfund
Program, administered by Environmental Protection
Administration (EPA) Under Superfund, companies found
10
responsible for pollution can be financially liable for the
cost of cleanup
Polychlorinated biphenyls (PCBs) are heavy, syrupy
hydrocarbons that were first synthesized in the 1880s
Because they conduct heat but not electricity and are
15
water-insoluble, fire-resistant, and extremely stable
(withstanding temperatures of up to 1600° F), PCBs were
found, in the 1930s, to be extremely useful as components
in cooling systems and electrical equipment (transformers
and capacitors) They were widely used for these purposes
20
and also in the composition of sealants, rubber, paints,
plastics, inks, and insecticides
PCBs were banned in 1979, after researchers linked
them to cancer and developmental problems in humans
However, PCBs persist in the environment for extremely
25
long periods Because PCBs have an affinity for fat, they
have a marked tendency to accumulate in living organisms;
increasing in concentration as they move up the food
chain While avoiding release of PCBs into the
environment is today a well-settled principle, what to do
30
about those already in the environment can be
controversial
Due to dumping over a period of 35 years by two
capacitor manufacturing plants located along the northern
part of the Hudson River in New York State, EPA has
35
estimated that 1.1 million pounds of PCBs have
accumulated Field surveys of the river have found
substantial contamination in 40 submerged sediment “hot
spots,” 5 exposed shoreline remnant deposits, dredge
spoils on riverbanks, and estuary sediments Today,
40
because of PCB contamination, human consumption of
fish caught in the most affected areas of the Hudson River
is prohibited But, while fish consumption remains the most potent route of PCB exposure, exposure can also occur through other routes Eight municipalities currently
45
draw drinking water from the Hudson and another, New York City, draws it during emergencies Furthermore, air along the river contains elevated concentrations of PCBs, and individuals living along the River show PCB residue
in their bodies, paralleling the river's contamination
50
EPA has recommended that PCBs be removed from the river bottom by dredging, thus reducing contamination and possibly eventually permitting revitalization of commercial fishing, which once generated $40 million income annually However, the corporation blamed for the
55
dumping argues that dredging may “stir up” the PCBs (which they describe as now “lying undisturbed” in the riverbed), causing the water, air, and riverbanks to become even more contaminated Some area residents echo these concerns and also argue that dredging will subject them to
60
years of unacceptable noise, disruption, and curtailed recreational activities
Although many take positions on whether dredging will have positive or negative consequences to the Hudson River Valley, there is only perfunctory attention to the
65
ultimate fate of the dredged PCBs EPA’s report recommending dredging indicates that, due to opposition
of local residents, neither a landfill nor a thermal treatment facility (for high temperature incineration) can be locally-sighted and the PCBs should therefore be transported to a
70
Toxic Substances Control Act or solid waste landfill outside of the area The report does not, however, identify
a specific location
Trang 41 It can be inferred from the passage that PCBs are:
I heavier than water
II toxic to fish
III readily biodegradable
A I only
B I and II only
C I and III only
D II and III only
2 An “estuary” is defined as the part of a wide, lower
course of a river where its current is met by the
tides Information contained in the passage indicates
that PCBs in estuary sediments most probably:
A originate from an additional source of
pollution not yet discovered
B indicate that PCBs in the river do not
necessarily remain where they were originally
deposited
C are present at a background level typical of the
earth’s environment as a whole
D indicate that all the PCBs currently in the river
can be expected to eventually end up in the
ocean
3 Based on information contained in the passage as a
whole, it can be inferred that the opinion of the
company responsible for PCB pollution of the
Hudson River, with respect to the appropriateness
of clean-up, is most probably:
A at least as objective as the opinion of area
residents
B reflective of its overriding concern with its
public image
C financially motivated
D indicative of its lack of connection to
commercial fishing interests
4 According to the passage, the EPA differs from
local residents and the company responsible for
PCB contamination in that it affirms that it bases its
recommended action on benefit to:
following pieces of additional information would
be most helpful to it in determining whether it should support the EPA recommendation to remove PCBs from the Hudson River by dredging?
A how present PCB levels in the river compare to
levels that existed prior to industrialization
B to what extent equipment to be used for
dredging can remove the PCBs without causing their release into the air and into upper river currents
C how the PCBs will be disposed of after
removal from the river
D the expected cost of the dredging operation
6 It can be inferred from the passage that the justification used for prohibiting individuals from consuming fish caught in contaminated sections of the Hudson River is that the individuals may thereby:
A reduce the level of PCBs in their bodies
B avoid any further increase in the level of PCBs
in their bodies
C mitigate the accumulation of PCBs in their
bodies
D prevent cancer and developmental problems
7 Which of the following is stated in the passage but
is not explained by facts or data contained in the passage?
A Individuals who live along the Hudson have a
concentration of PCBs in their bodies that parallel the concentration of the substances in the river
B PCBs were useful as components of electrical
equipment and cooling systems
C PCBs accumulate in living organisms
D What should be done about PCBs which
contaminate the environment is controversial
Trang 5Passage II (Questions 8–14)
With equal justice, the council of Pisa deposed the
popes of Rome and Avignon; the conclave was unanimous
in the choice of Alexander V, and his vacant seat was soon
filled by a similar election of John XXIII, the most
profligate of mankind But instead of extinguishing the
5
schism, the rashness of the French and Italians had given a
third pretender to the chair of St Peter Such new claims
of the synod and conclave were disputed; three kings, of
Germany, Hungary, and Naples, adhered to the cause of
Gregory XII; and Benedict XIII, himself a Spaniard, was
10
acknowledged by the devotion and patriotism of that
powerful nation
The rash proceedings of Pisa were corrected by the
council of Constance; the emperor Sigismond acted a
conspicuous part as the advocate or protector of the
15
Catholic church; and the number and weight of civil and
ecclesiastical members might seem to constitute the
states-general of Europe Of the three popes, John XXIII was the
first victim: he fled and was brought back a prisoner: the
most scandalous charges were suppressed; the vicar of
20
Christ was only accused of piracy, murder, rape, sodomy,
and incest; and after subscribing his own condemnation, he
expiated in prison the imprudence of trusting his person to
a free city beyond the Alps Gregory XII, whose obedience
was reduced to the narrow precincts of Rimini, descended
25
with more honour from the throne; and his ambassador
convened the session, in which he renounced the title and
authority of lawful pope To vanquish the obstinacy of
Benedict XIII or his adherents, the emperor in person
undertook a journey from Constance to Perpignan The
30
kings of Castile, Arragon, Navarre, and Scotland, obtained
an equal and honourable treaty; with the concurrence of
the Spaniards, Benedict was deposed by the council; but
the harmless old man was left in a solitary castle to
excommunicate twice each day the rebel kingdoms which
35
had deserted his cause
After thus eradicating the remains of the schism, the
synod of Constance proceeded with slow and cautious
steps to elect the sovereign of Rome and the head of the
church On this momentous occasion, the college of
40
twenty-three cardinals was fortified with thirty deputies;
six of whom were chosen in each of the five great nations
of Christendom, – the Italian, the German, the French, the
Spanish, and the English: the interference of strangers was
softened by their generous preference of an Italian and a
45
Roman; and the hereditary, as well as personal, merit of
Otho Colonna recommended him to the conclave Rome
accepted with joy and obedience the noblest of her sons;
the ecclesiastical state was defended by his powerful
family; and the elevation of Martin V is the era of the
50
restoration and establishment of the popes in the Vatican
8 It can be inferred that a goal shared by the Council
of Pisa and the Council of Constance was to:
A reunite the Catholic Church under a single
pope
B forge an alliance between the most powerful
nations in Europe
C obtain for the Catholic Church the protection
of the Emperor Sigismond
D appoint a native Roman to the papacy
9 According to the passage, why was the Council of Constance more successful than the Council of Pisa?
I The Council of Constance made sure that
it had the support of the most important European powers
II The Council of Constance elected a pope
who was more virtuous than any of his rivals
III The Council of Constance elected a pope
who was already respected by the Roman people
A I and II
B I and III
C II and III
D I, II, and III
10 Why does the author distinguish between “the most scandalous charges” against John XXIII, and the charges of which he was actually accused?
A to demonstrate the leniency of the Council of
Constance
B to suggest how serious the suppressed charges
must have been
C to give an example of John XXIII’s political
influence
D to show the importance of electing an Italian to
the papacy
Trang 611 How did the Spanish contribute to the resolution of
the division within the Catholic Church?
A They encouraged the cardinals to revolt, and
they deposed the two reigning popes
B They opposed the French and Italians, and they
supported Benedict XIII
C They protected the Catholic Church, and they
prosecuted John XXIII
D They agreed to the deposal of Benedict XIII,
and they helped to elect Martin V
12 It can be inferred that the author would agree with
which of the following statements about Benedict
XIII, Gregory XII, and John XXIII?
A Benedict XIII was the best of the three
B Gregory XII was the best of the three
C None of the three deserved to be pope
D John XXIII had the best claim to having been
legitimately elected
13 The passage suggests that if John XXIII had been generally acceptable to Catholics throughout Europe, which of the following would have resulted?
A Benedict XIII and Gregory XII would not have
been deposed
B the Council of Constance would not have taken
place
C the Catholic Church would not have been
reunited
D the papal seat would not have been moved back
to Rome
14 At the Council of Constance, why were the 23 cardinals joined by 30 deputies?
A to make sure that their choice for pope was
acceptable to the most important European states
B to prevent them escaping
C to protect them from governmental interference
D to make sure that they maintained a proper
level of decorum
Trang 7Passage III (Questions 15–21)
Until recently, most scientists believed that memory
inevitably deteriorates with age One commonly cited
example of this deterioration is the fact that elderly people
often cannot remember recent events, even though they
may recall details from the distant past But contemporary
5
research into how the mind stores and retrieves
information refutes the notion of the inevitable decline in
memory New studies suggest that we have more than one
kind of memory, and imply that elderly people who suffer
from forgetfulness can utilize other types of memory to
10
compensate for the decline
This new conception of memory stems from a shift in
methodology of memory research While older studies of
memory and aging involved comparisons between
different age groups, recent investigations tested the same
15
group of people over a number of years Such
longitudinal data more clearly establishes the relationship
between memory and aging Through these studies of
older adults, researchers concluded that there exist three
major kinds of memory, only one of which declines in old
20
age
Previous investigations into the workings of memory
usually tested “episodic” memory, which describes the
recall of specific events, as well as the ability to remember
names and the whereabouts of items like car keys This
25
ability usually remains intact until the mid-sixties, when
people often become forgetful of things like recent events
and minor details While some researchers suggest that
this well-known decline in episodic memory in the elderly
stems from degeneration of the frontal lobes of the brain,
30
many scientists believe that such memory loss is largely
due to retirement: after the demands of work stop, most
people no longer exercise their mental faculties as
strenuously Thus, regular mental “exercise” might curtail
memory loss
35
But episodic memory comprises only part of this
intricate brain function Memory researchers have
identified two other types of memory, neither of which
seems to deteriorate with age “Semantic” memory, which
describes our ability to recall knowledge and facts as well
40
as events in the distant past, does not seem to lessen over
the course of a lifetime In fact, such memory may be even
sharper in elderly people than in the young or middle-aged
When a group of men and women in their sixties were
tested on a specific vocabulary list and retested on the
45
same list a decade later, the group had improved their
scores by an average of six words—an increase researchers
consider substantial Such studies suggest that by taking
notes or mulling over events, elderly people who suffer
from forgetfulness can store more information in the
50
semantic memory, thus compensating for episodic memory
loss
A third type of memory, “implicit” memory, deals with the tremendous variety of mental activities we perform without making any intentional effort Examples of these
55
include actions like driving a car, touch-typing, or riding a bicycle Scientists have learned through observations of amnesiacs that this type of memory is distinct from both episodic and semantic memory In one such study, an amnesiac patient who had been an avid golfer before
60
developing a memory problem remembered which club to use for each stroke; however, he forgot that he had played
a hole within minutes of having done so In addition, further studies of amnesiacs have shown that people with these disorders can learn new facts but cannot remember
65
when and where they had learned them Studies of people
in their sixties and seventies showed similar results: like amnesiacs, older people are able to learn from new experience as well as younger people, but often have difficulty remembering the source of their knowledge or
70
skill
Such studies into the structure of memory shed new light on the problems of memory loss in the aged While the findings are encouraging, it must be noted that such studies do not deal with memory problems associated with
75
illness, disease, or injury to the brain
15 The passage implies that advanced age might adversely affect which of the following?
I memory of details of a recent conversation
II recollection of childhood memories
III ability to perform routine tasks
A I only
B II only
C III only
D I and II only
Trang 816 The author’s attitude might be described as one of:
A unbridled enthusiasm
B wary skepticism
C reserved optimism
D unbiased objectivity
17 The primary purpose of the passage is to:
A discuss the ways in which a new theory of
memory challenges common assumptions
regarding memory and aging
B explain why past investigations into memory
tested only episodic memory
C describe recent research into the functioning of
the brain
D consider the reasons why episodic memory
diminished in later years
18 It can be inferred from the passage that recent
developments in memory research can be attributed
largely to:
A scientists’ efforts to dismantle stereotypes
regarding the abilities of elderly persons
B recent discoveries that distinguish age-related
forgetfulness from disease and injury-related
memory loss
C the realization that mental exercise frequently
diminishes memory loss
D new methodologies that clarify the relationship
between memory and aging
19 According to the passage, older people often forget
recent events but remember the distant past because:
A childhood events exist as part of implicit
memory
B episodic memory declines while implicit
memory does not
C episodic memory declines but semantic
memory improves with age
D retired elderly people make few demands on
their semantic memory
20 The passage suggests that an elderly person who cannot remember how to tie her shoes is most probably suffering from:
A amnesia
B semantic memory loss
C episodic memory loss
D implicit memory loss
21 Based on the information in the passage, the author would probably agree with which of the following statements regarding memory problems associated with illness, disease, or injury?
A Since many elderly suffer from such organic
dysfunctions, memory research remains more theoretical than practical
B Scientists hope that these studies will
contribute to our understanding of these disorders as well
C It is likely that researchers will turn toward
these more critical problems in the near future
D Since such disorders do not conform to the
tripartate model of memory, most researchers are not interested in them
Trang 9Passage IV (Questions 22–28)
What is the value of learning about hypotheses that
were once espoused to explain an observed phenomenon,
but that have now been long disproved and invalidated?
Some students may feel that we should not focus on the
past, and that our thoughts should be trained on new
5
knowledge and invention, rather than antiquated ideas
What these students do not understand is the importance of
the old ideas in shaping our current understanding of the
world around us, and that an outright dismissal of past
theories simply because they have been rejected by new
10
evidence may limit our understanding of current theories
Darwin’s theory of natural selection as the mechanism
for evolution is all too often taught in a vacuum in high
school biology classrooms, as if this brilliant naturalist
developed a groundbreaking theory on natural order which
15
had never before been contemplated in any form It is only
by learning about the gradual development of evolutionary
theory, and the role of some rather religious individuals in
shaping this theory, that students may come to see the
logic and power behind Darwin’s relatively simple ideas
20
Many of the contributions upon which Darwin built his
ideas came from scientists who were staunch creationists
themselves These scientists believed that all organisms on
Earth had been placed here by “special creation,” by God,
because there was little evidence at the time to support
25
evolution
Carolus Linnaeus, who developed a framework for
modern systems of taxonomy and classification in the
1700s, actually undertook his research with the hope of
discovering patterns of God’s creation Georges LeClerc
30
(1707-1788) proposed a mechanism for calculating the
age of the Earth using molten spheres of iron and
measuring cooling times, after which he proposed that the
Earth was at least 75,000 years old and perhaps as old as
three million years LeClerc also perceived that species
35
were not fixed and could change over time; he even
proposed that closely related species, such as the horse and
donkey, had developed from a common ancestor and had
been modified by different climactic conditions Yet,
LeClerc was a devout Christian creationist and devoted
40
much of his writing to the debunking of evolutionary
ideas Despite their commitments to religion, LeClerc and
Linnaeus both gave Darwin crucial raw material to work
with – their ideas concerning the similarities between
related species and possible connections with common
45
ancestors cried out for a reasonable explanation
For centuries before Darwin, data that challenged the
biblical account of creation was surfacing in many fields
of research As explorers began to study the forces that
shape the Earth, such as mountain building and volcanic
50
eruptions, accounts from scripture and assertions that the
Earth was very young began to be called into question
Uniformitarian geologists such as Charles Lyell felt that
the only reason mountains and other features of the Earth’s terrain had been built the way they had was
55
because of long, gradual processes that shaped these structures There was no way, he felt, that the Earth could
be several thousand years old as asserted in the Bible In addition, the discovery of new plants, animals, and fossils
as explorers traveled to uncharted regions of the world
60
aroused suspicion about the paucity of animal and plant
“kinds” in the Bible Improvements in scientists’ abilities
to estimate the age of the Earth and the relative ages of fossils also pushed people to question old assumptions
22 The main idea of this passage is that:
A religious scientists before Darwin greatly
influenced his formation of the theory of natural selection
B similarities between species of plants and
animals were too great to ignore as people attempted to explain relationships in nature
C Darwin relied on a great deal of information
from those who lived before him as he formed his well-known conclusions about the mechanisms of evolution
D old ideas should not be dismissed simply
because they are old and disproved
23 Findings that challenged Biblical accounts of creation included all of the following EXCEPT:
A similarities between related species, such as
donkeys and horses
B indications that mountain building processes
took tens of thousands of years
C findings of a great diversity of new plants and
animals across a variety of habitats
D fossil findings indicating that the Earth was, in
fact, tens of thousands of years old or more
Trang 1024 If the author were teaching a class on evolution,
the passage suggests that the class would spend a
significant amount of time discussing:
A the origins of Darwin’s theory of natural
selection
B details of Darwin’s theory of natural selection
C the Biblical account of creation
D taxonomy and classification and their
importance in Darwin’s ideas
25 Georges Le Clerc’s ideas on evolution may have
been closest to those of:
A Darwin, because LeClerc focused much of his
research on understanding similarities between
related plants and animals
B Linnaeus, because they were both devout
Christians who attempted to explain natural
phenomena in a supernatural light
C Lyell, because both scientists concluded that
the supposed age of the Earth could not
account for certain measured features
D Linnaeus, because both scientists gave Darwin
important raw material to work with as Darwin
formulated his ideas on natural selection
26 The author’s discussion of Darwin’s theory in
paragraph 2 of the passage suggests that:
A Darwin does not deserve the credit he is given
for his ideas on evolutionary theory
B Darwin’s theories should be presented in the
context within which they were originally
conceived
C Darwin’s ideas would be properly devalued if
people knew the religious background from
which his ideas stemmed
D Darwin’s ideas are simple enough that he didn’t
need much help in formulating them
27 With respect to his claim that students need to understand and appreciate old theories, the author asserts that:
I Darwin’s theory of natural selection cannot be understood or applied without the knowledge of evolutionary hypotheses that came before him
II Even now-debunked concepts, such as
LeClerc’s melting iron spheres to calculate Earth’s age, are important in building a complete picture of how Darwin came to his revolutionary theory III Learning about Linnaeus’ classification
schemes would help students see how Linnaeus’ work gave Darwin a body of knowledge that needed proper explaining
A I and II
B II only
C II and III
D I, II, and III
28 According to the passage, the idea that mountains and other structures take a great deal of time to form was an idea championed by:
A catastrophists
B Darwinists
C creationists
D uniformitarians
