1. Questions 1–10 are based on the following passage.
2. The following passage is adapted from Leo Tolstoy’s 1873 novel,
Anna Karenina (translated from the original Russian by Constance
Garnett). Prior to this excerpt, one of the major characters, Levin,
has realized that he is in love with his longtime friend Kitty
Shtcherbatsky.
At four o’clock, conscious of his throbbing heart,
Levin stepped out of a hired sledge at the Zoological
Gardens, and turned along the path to the frozen
mounds and the skating ground, knowing that he
would certainly find her there, as he had seen the
Shtcherbatskys’ carriage at the entrance.
It was a bright, frosty day. Rows of carriages,
sledges, drivers, and policemen were standing in the
approach. Crowds of well-dressed people, with hatsbright in the sun, swarmed about the entrance and
along the well-swept little paths between the little
houses adorned with carving in the Russian style.
The old curly birches of the gardens, all their twigs
laden with snow, looked as though freshly decked
in sacred vestments.
He walked along the path towards the skatingground, and kept saying to
himself—“You mustn’t
be excited, you must be calm. What’s the matter
with you? What do you want? Be quiet, stupid,”
he conjured his heart. And the more he tried to
compose himself, the more breathless he found
himself. An acquaintance met him and called him
by his name, but Levin did not even recognize
him. He went towards the mounds, whence came
the clank of the chains of sledges as they slipped
down or were dragged up, the rumble of the sliding
sledges, and the sounds of merry voices. He walked
on a few steps, and the skating-ground lay open
before his eyes, and at once, amidst all the skaters,
he knew her.
He knew she was there by the rapture and the
terror that seized on his heart. She was standing
talking to a lady at the opposite end of the ground.
There was apparently nothing striking either inher dress or her attitude. But for Levin she was as
easy to find in that crowd as a rose among nettles.
Everything was made bright by her. She was the
smile that shed light on all round her. “Is it possible
I can go over there on the ice, go up to her?” he
thought. The place where she stood seemed to
him a holy shrine, unapproachable, and there was
one moment when he was almost retreating, so
overwhelmed was he with terror. He had to make
an effort to master himself, and to remind himself
that people of all sorts were moving about her, and
that he too might come there to skate. He walked
down, for a long while avoiding looking at her as at
the sun, but seeing her, as one does the sun, without
looking.
On that day of the week and at that time of day
people of one set, all acquainted with one another,
used to meet on the ice. There were crack skaters
there, showing off their skill, and learners clinging
to chairs with timid, awkward movements, boys,
and elderly people skating with hygienic motives.
They seemed to Levin an elect band of blissful
beings because they were here, near her. All the
skaters, it seemed, with perfect self-possession,
skated towards her, skated by her, even spoke to her,and were happy, quite apart from her, enjoying the
capital ice and the fine weather.
Nikolay Shtcherbatsky, Kitty’s cousin, in a short
jacket and tight trousers, was sitting on a garden
seat with his skates on. Seeing Levin, he shouted
to him:
“Ah, the first skater in Russia! Been here long?
First-rate ice—do put your skates on.”

1. Questions 11–20 are based on the following passage.
2. This passage is adapted from a speech delivered by PresidentFranklin Roosevelt on January 6, 1941, to the United States
Congress. In the passage, Roosevelt reveals his intention to
preserve and spread American ideals around the world.
The Nation takes great satisfaction and much
strength from the things which have been done to
make its people conscious of their individual stake
in the preservation of democratic life in America.
Those things have toughened the fibre of our
people, have renewed their faith and strengthened
their devotion to the institutions we make ready
to protect.
Certainly this is no time for any of us to stop
thinking about the social and economic problems
which are the root cause of the social revolution
which is today a supreme factor in the world.
For there is nothing mysterious about the
foundations of a healthy and strong democracy. The
basic things expected by our people of their political
and economic systems are simple. They are:
• Equality of opportunity for youth and for others.
• Jobs for those who can work.
• Security for those who need it.
• The ending of special privilege for the few.
• The preservation of civil liberties for all.
• The enjoyment of the fruits of scientific progressin a wider and constantly rising standard of living.
These are the simple, basic things that must never
be lost sight of in the turmoil and unbelievable
complexity of our modern world. The inner and
abiding strength of our economic and political
systems is dependent upon the degree to which they
fulfill these expectations.
Many subjects connected with our social
economy call for immediate improvement.
As examples:
• We should bring more citizens under the coverage
of old-age pensions and unemployment insurance.
• We should widen the opportunities for adequate
medical care.
• We should plan a better system by which persons
deserving or needing gainful employment may
obtain it.
I have called for personal sacrifice. I am assured
of the willingness of almost all Americans to
respond to that call.
A part of the sacrifice means the payment of
more money in taxes. In my Budget Message I shall
recommend that a greater portion of this great
defense program be paid for from taxation than
we are paying today. No person should try, or beallowed, to get rich out of this program; and the
principle of tax payments in accordance with ability
to pay should be constantly before our eyes to guide
our legislation.
If the Congress maintains these principles, the
voters, putting patriotism ahead of pocketbooks,
will give you their applause.
In the future days, which we seek to make secure,
we look forward to a world founded upon four
essential human freedoms.
The first is freedom of speech and expression—
everywhere in the world.
The second is freedom of every person to worship
God in his own way—everywhere in the world.
The third is freedom from want—which,
translated into world terms, means economic
understandings which will secure to every nation
a healthy peacetime life for its inhabitants—
everywhere in the world.
The fourth is freedom from fear—which,
translated into world terms, means a world-wide
reduction of armaments to such a point and in
such a thorough fashion that no nation will be in
a position to commit an act of physical aggression
against any neighbor—anywhere in the world.That is no vision of a distant millennium. It is a
definite basis for a kind of world attainable in our
own time and generation. That kind of world is the
very antithesis of the so-called new order of tyranny
which the dictators seek to create with the crash of
a bomb.
To that new order we oppose the greater
conception—the moral order. A good society is able
to face schemes of world domination and foreign
revolutions alike without fear.
Since the beginning of our American history,
we have been engaged in change—in a perpetual
peaceful revolution—a revolution which goes
on steadily, quietly adjusting itself to changing
conditions—without the concentration camp or the
quick-lime in the ditch. The world order which we
seek is the cooperation of free countries, working
together in a friendly, civilized society.
This nation has placed its destiny in the hands
and heads and hearts of its millions of free men and
women; and its faith in freedom under the guidance
of God. Freedom means the supremacy of human
rights everywhere. Our support goes to those
who struggle to gain those rights or keep them.
Our strength is our unity of purpose. To that highconcept there can be no end save victory.

1. Questions 21–31 are based on the following passage and
supplementary material.
2. The United States Constitution has been amended 27 times since its
ratification. Rights such as freedom of speech, religion, and press,for example, are granted by the First Amendment. This passage
focuses on the Nineteenth Amendment, which gave women the
right to vote.
The American political landscape is constantly
shifting on a myriad of issues, but the voting
process itself has changed over the years as well.
Electronic ballot casting, for example, provides the
public with instantaneous results, and statisticians
are more accurate than ever at forecasting our next
president. Voting has always been viewed as an
intrinsic American right and was one of the major
reasons for the nation’s secession from Britain’s
monarchical rule. Unfortunately, although all men
were constitutionally deemed “equal,” true equality
of the sexes was not extended to the voting booth
until 1920.
The American women’s suffrage movement
began in 1848, when Elizabeth Cady Stanton
and Lucretia Mott organized the Seneca Falls
Convention. The meeting, initially an attempt
to have an open dialogue about women’s rights,
drew a crowd of nearly three hundred women and
included several dozen men. Topics ranged from
a woman’s role in society to law, but the issue of
voting remained a contentious one. A freed slavenamed Frederick Douglass spoke eloquently about
the importance of women in politics and swayed
the opinion of those in attendance. At the end of the
convention, one hundred people signed the Seneca
Falls Declaration, which demanded “immediate
admission to all the rights and privileges which
belong to [women] as citizens of the United States.”
Stanton and Mott’s first victory came thirty years
later when a constitutional amendment allowing
women to vote was proposed to Congress in 1878.
Unfortunately, election practices were already a
controversial issue, as unfair laws that diminished
the African American vote had been passed during
Reconstruction. Questionable literacy tests and a
“vote tax” levied against the poor kept minority
turnout to a minimum. And while several states
allowed women to vote, federal consensus was
hardly as equitable. The rest of the world, however,
was taking note—and women were ready to act.
In 1893, New Zealand allowed women the right
to vote, although women could not run for office
in New Zealand. Other countries began reviewing
and ratifying their own laws as well. The United
Kingdom took small steps by allowing married
women to vote in local elections in 1894. By 1902,all women in Australia could vote in elections, both
local and parliamentary.
The suffrage movement in America slowly built
momentum throughout the early twentieth century
and exploded during World War I. President
Woodrow Wilson called the fight abroad a war
for democracy, which many suffragettes viewed as
hypocritical. Democracy, after all, was hardly worth
fighting for when half of a nation’s population was
disqualified based on gender. Public acts of civil
disobedience, rallies, and marches galvanized prowomen advocates while
undermining defenders
of the status quo. Posters read “Kaiser Wilson”
and called into question the authenticity of a free
country with unjust laws. The cry for equality
was impossible to ignore and, in 1919, with the
support of President Wilson, Congress passed the
Nineteenth Amendment to the Constitution. It was
ratified one year later by three-quarters of the states,
effectively changing the Constitution. Only one
signatory from the original Seneca Falls Declaration
lived long enough to cast her first ballot in a federal
election.
America’s election laws were far from equal
for all, as tactics to dissuade or prohibit AfricanAmericans from effectively voting were still
routinely employed. However, the suffrage
movement laid the groundwork for future
generations. Laws, like people’s minds, could
change over time. The civil rights movement in the
mid- to late-twentieth century brought an end to
segregation and so-called Jim Crow laws that stifled
African American advancement. The Voting Rights
Act of 1965 signaled the end of discriminatory
voting laws; what emerged was a free nation guided
by elections in which neither skin color nor gender
mattered, but only the will of all citizens.
T3h.e stance the author takes in the passage is best described as thatof
1. an advocate of women’s suffrage proposing a
constitutional amendment.
2. a legislator reviewing the arguments for and against
women’s suffrage.
3. a scholar evaluating the evolution and impact of the
women’s suffrage movement.
4. a historian summarizing the motivations of women’s
suffrage leaders.
L4i.nes 71–72 (“America’s election laws . . . equal for all”) most
clearly support which claim?
1. The founders of the Constitution did not provide for free
and fair elections.
2. The United States still had work to do to secure equal
voting rights for some people.
3. Most women in the United States did not want suffrage
and equal rights.
4. The women’s suffrage movement perpetuated
discriminatory voting laws.
W5.hich choice provides the best evidence for the answer to the
previous question?
1. Lines 14–15 (“The American . . . in 1848”)
2. Lines 42–43 (“In 1893 . . . to vote”)
3. Lines 64–65 (“Congress . . . the Constitution”)
4. Lines 80–81 (“The Voting Rights Act . . . voting laws”)A6s. used in line 58, “galvanized” most nearly means
1. displaced.
2. divided.
3. excited.
4. organized.
T7h.e function of lines 76–77 (“Laws, like . . . could change”) is to

public sentiment.
2. dissuade reformers from focusing on grassroots activity
rather than political campaigns.
3. evaluate the effectiveness of judicial rulings based on
popular response to public polls.
4. reject the need for legal actions and court proceedings to
attain social change.
T8h.e passage most strongly suggests that
1. the American government adapts to the changing needs
and ideas of society.
2. the best-organized reform movements are most likely to
achieve their goals.
3. the nation is more vulnerable to change during the
confusion of wartime.
4. the civil rights movement would not have happened
without women suffragists.
W9.hich choice provides the best evidence for the answer to the
previous question?1. Lines 4–7 (“Electronic ballot casting . . . our next
president”)
2. Lines 7–10 (“Voting has . . . monarchical rule”)
3. Lines 17–20 (“The meeting . . . dozen men”)
4. Lines 77–80 (“The civil rights . . . advancement”)
1T0h.e graphic most clearly illustrates which idea?
1. The Nineteenth Amendment happened as a result of World
War I.
2. The states slowed reform of national voting rights laws.
3. Women’s suffrage resulted from a slow evolution of
events.
4. Acts of civil disobedience won support for suffrage in
Congress.
1I1n.line 61, the word “authenticity” most nearly means
1. reliability.
2. realism.
3. legitimacy.
4. truth.
1T2h.e passage suggests that President Wilson contributed to the
success of the women’s suffrage movement by
1. circulating government propaganda in support of women’s
suffrage.
2. framing the fight in World War I as a fight for democracy
and freedom.
3. engaging in a foreign war to distract the nation frompolitical debate.
4. working with legislators to write the Nineteenth
Amendment.
1T3h.e graphic helps support which statement referred to in the
passage?
1. Early women suffragists did not live to vote in national
elections.
2. The Nineteenth Amendment passed within a few years of
its introduction.
3. A majority of state representatives opposed women’s
suffrage in 1918.
4. Many state governments approved suffrage before the
federal government did.
4.
1. Questions 32–42 are based on the following passages and
supplementary material.
2. Passage 1 is about how scientists use radioisotopes to date artifacts
and remains.
Passage 2 discusses the varying problems with radioactive
contaminants.
Passage 1
Archaeologists often rely on measuring the
amounts of different atoms present in an item from
a site to determine its age. The identity of an atom
depends on how many protons it has in its nucleus; forexample, all carbon atoms have 6 protons. Each atom
of an element, however, can have a different number of
neutrons, so there can be several versions, or isotopes,
of each element. Scientists name the isotopes by the
total number of protons plus neutrons. For example,
a carbon atom with 6 neutrons is carbon-12 while a
carbon atom with 7 neutrons is carbon-13.
Some combinations of protons and neutrons are
not stable and will change over time. For example,
carbon-14, which has 6 protons and 8 neutrons, will
slowly change into nitrogen-14, with 7 protons and 7
neutrons. Scientists can directly measure the amount
of carbon-12 and carbon-14 in a sample or they
can use radiation measurements to calculate these
amounts. Each atom of carbon-14 that changes to
nitrogen-14 emits radiation. Scientists can measure
the rate of emission and use that to calculate the total
amount of carbon-14 present in a sample.
Carbon-14 atoms are formed in the atmosphere
at the same rate at which they decay. Therefore,
the ratio of carbon-12 to carbon-14 atoms in the
atmosphere is constant. Living plants and animals
have the same ratio of carbon-12 to carbon-14 in
their tissues because they are constantly taking in
carbon in the form of food or carbon dioxide. Afterthe plant or animal dies, however, it stops taking in
carbon and so the amount of carbon-14 atoms in its
tissues starts to decrease at a predictable rate.
By measuring the ratio of carbon-12 to carbon-14
in a bone, for example, a scientist can determine
how long the animal the bone came from has
been dead. To determine an object’s age this way
is called “carbon-14 dating.” Carbon-14 dating can
be performed on any material made by a living
organism, such as wood or paper from trees or
bones and skin from animals. Materials with ages up
to about 50,000 years old can be dated. By finding
the age of several objects found at different depths
at an archeological dig, the archeologists can then
make a timeline for the layers of the site. Objects
in the same layer will be about the same age. By
using carbon dating for a few objects in a layer,
archeologists know the age of other objects in that
layer, even if the layer itself cannot be carbon dated.
Passage 2
Radioactive materials contain unstable atoms that
decay, releasing energy in the form of radiation. The
radiation can be harmful to living tissue because
it can penetrate into cells and damage their DNA.
If an explosion or a leak at a nuclear power plantreleases large amounts of radioactive materials,
the surrounding area could be hazardous until the
amount of radioactive material drops back to normal
levels. The amount of danger from the radiation and
the amount of time until the areas are safe again
depends on how fast the materials emit radiation.
Scientists use the “half-life” of a material to indicate
how quickly it decays. The half-life of a material is
the amount of time it takes for half of a sample of
that material to decay. A material with a short halflife decays more quickly
than a material with a long
half-life. For example, iodine-131 and cesium-137
can both be released as a result of an accident at a
nuclear power plant. Iodine-131 decays rapidly, with a
half-life of 8 days. Cesium-137, however, decays more
slowly, with a half-life of 30 years.
If an accident releases iodine-131, therefore, it is a
short-term concern. The amount of radiation emitted
will be high but will drop rapidly. After two months,
less than one percent of the original iodine-131
will remain. An accidental release of cesium-137,
however, is a long-term concern. The amount of
radiation emitted at first will be low but will drop
slowly. It will take about 200 years for the amount of
cesium-137 remaining to drop below one percent.The total amount of radiation emitted in both cases
will be the same, for the same amount of initial
material. The difference lies in whether the radiation
is all released rapidly at high levels in a short time, or
is released slowly at low levels, over a long time span.

could be dated using carbon-14 dating?

1. Questions 43–52 are based on the following passage and
supplementary material.
2. The following passage is adapted from an essay about the field of
biomimicry, which focuses on the design of materials and systems
that are based on biological structures.In 1948, Swiss chemist George de Mestral
was impressed with the clinging power of burrs
snagged in his dog’s fur and on his pant legs after
he returned from a hike. While examining the
burrs under a microscope, he observed many
hundreds of small fibers that grabbed like hooks.
He experimented with replicas of the burrs and
eventually invented Velcro®, a synthetic clinging
fabric that was first marketed as “the zipperless
zipper.” In the 1960s, NASA used de Mestral’s
invention on space suits, and now, of course, we see
it everywhere.
You might say that de Mestral was the father
of biomimicry, an increasingly essential field that
studies nature, looking for efficiencies in materials
and systems, and asks the question “How can our
homes, our electronics, and our cities work better?”
As one biomimetics company puts it: “Nature is the
largest laboratory that ever existed and ever will.”
Architecture is one field that is constantly
exploring new ways to incorporate biomimicry.
Architects have studied everything from beehives
to beaver dams to learn how to best use materials,
geometry, and physics in buildings. Termite
mounds, for example, very efficiently regulatetemperature, humidity, and airflow, so architects
in Zimbabwe are working to apply what they’ve
learned from termite mounds to human-made
structures.
Says Michael Pawlyn, author of Biomimicry in
Architecture, “If you look beyond the nice shapes
in nature and understand the principles behind
them, you can find some adaptations that can lead
to new, innovative solutions that are radically more
resource-efficient. It’s the direction we need to take
in the coming decades.”
Designers in various professional fields are
drawing on biomimicry; for example, in optics,
scientists have examined the surface of insect eyes
in hopes of reducing glare on handheld device
screens. Engineers in the field of robotics worked
to replicate the property found in a gecko’s feet that
allows adhesion to smooth surfaces.
Sometimes what scientists learn from nature
isn’t more advanced, but simpler. The abalone
shrimp, for example, makes its shell out of calcium
carbonate, the same material as soft chalk. It’s
not a rare or complex substance, but the unique
arrangement of the material in the abalone’s shell
makes it extremely tough. The walls of the shellcontain microscopic pieces of calcium carbonate
stacked like bricks, which are bound together using
proteins just as concrete mortar is used. The result
is a shell three thousand times harder than chalk
and as tough as Kevlar® (the material used in bulletproof vests).
Often it is necessary to look at the nanoscale
structures of a living material’s exceptional
properties in order to re-create it synthetically.
Andrew Parker, an evolutionary biologist, looked at
the skin of the thorny devil (a type of lizard) under
a scanning electron microscope, in search of the
features that let the animal channel water from its
back to its mouth.
Examples like this from the animal world
abound. Scientists have learned that colorful birds
don’t always have pigment in their wings but are
sometimes completely brown; it’s the layers of
keratin in their wings that produce color. Different
colors, which have varying wavelengths, reflect
differently through keratin. The discovery of this
phenomenon can be put to use in creating paints
and cosmetics that won’t fade or chip. At the same
time, paint for outdoor surfaces can be made
tougher by copying the structures found in antler
bone. Hearing aids are being designed to capturesound as well as the ears of the Ormia fly do. And
why can’t we have a self-healing material like our
own skin? Researchers at the Beckman Institute at
the University of Illinois are creating just that; they
call it an “autonomic materials system.” A raptor’s
feathers, a whale’s fluke, a mosquito’s proboscis—all
have functional features we can learn from.
The driving force behind these innovations, aside
from improved performance, is often improved
energy efficiency. In a world where nonrenewable
energy resources are dwindling and carbon
emissions threaten the planet’s health, efficiency
has never been more important. Pawlyn agrees:
“For me, biomimicry is one of the best sources of
innovation to get to a world of zero waste because
those are the rules under which biological life has
had to exist.”
Biomimicry is a radical field and one whose
practitioners need to be radically optimistic, as
Pawlyn is when he says, “We could use natural
products such as cellulose, or even harvest carbon
from the atmosphere to create bio-rock.”

center are arranged in an interlocking spiral, which inspired
engineers in the design of this solar power plant. Mirrors positionedat the same angle as the florets bounce light toward the power

B6a.sed on the information in paragraph 6, how does the shell of an
abalone shrimp compare with soft chalk?
1. The essential building blocks are arranged in a similar
manner, but the material that makes up the shell of an
abalone shrimp is harder.
2. Both are made from the same essential building blocks,
but the shell of the abalone shrimp is much harder because
of the manner in which the materials are arranged.
3. The essential building blocks of both are the same, but the
abalone shrimp shell is harder because the soft chalk lacks
a protein binding the materials together.
4. They are made from different essential building blocks,
but they have a similar hardness because the materials are
arranged in a similar manner.
