Physical geography studies the features of the Earth’s surface This branch of geography looks at climate, plant
and animal life, bodies of water, and landforms Maps are the most important tool of geography Topographical maps give details about land They show different elevations above and below sea level Globes and world maps
show oceans, seas, and the seven continents of the planet

Geography
IN THE geography section of the GED, you will be asked to answer
questions relating to both physical geography (the features of the Earth’s surface) and cultural geography (the way humans relate to their physical environment)

Trang 2Reading and Understanding Maps
Intersecting lines that form a grid help locate specific
areas on a world map Lines of latitude run parallel to the
equator, an imaginary line that runs east and west The
equator is at 0° latitude It divides the globe into two
halves, called the northern and southern hemispheres.
Lines of longitude run parallel to the prime meridian, an
imaginary that runs north and south through
Green-wich, England The prime meridian is at 0° longitude It
divides the globe into two halves, called the eastern and
western hemispheres To find a specific location on the
globe, look for the point where its latitude and longitude
intersect For example, you can find the western portion
of Brazil if you are given its coordinates as 45° west
lon-gitude and 10° south latitude
C l i m a t e
Climate describes the atmosphere of a region over a long
period of time It includes rainfall, humidity, wind, and
other elements A region’s climate is most affected by its
latitude Broad areas, called climatic zones, lie along
lati-tudinal lines between the equator and the north and
south pole The tropical zone includes all land and water
that falls between two imaginary lines called the Tropic of
Cancer (23.5 north latitude) and the Tropic of Capricorn
(23.5 south latitude) The tropics—hot, wet, with little
seasonal change—contain the world’s largest rainforests
It also contains savanna and desert climates Much of Africa, Central America, the Caribbean, South America, Southeast Asia, and India are part of the tropical zone
The temperate zones lie between the tropics and the
polar circles They are characterized by four seasons, usu-ally a hot summer, cold winter, and intermediate spring and fall Much of North America, Europe, Russia, China, and the Middle East are found in the northern temperate zone Australia and the southern part of South America fall within the southern temperate zone The
polar or arctic zones are the areas near the north and
south pole This zone is characterized by long, cold
win-ters and short, cool summers The Arctic Circle marks the region near the north pole and the Antarctic Circle marks
the area surrounding the south pole

Cultural geography explores the relationship between humans and their natural environment It looks at how people both adapt to and transform their physical
sur-roundings to suit their needs Many aspects of culture—
a shared way of living among a group of people that develops over time—are influenced by environment Geographers study the belief systems, language, food, architecture, and clothing of particular regions
They also study population—the size, makeup, and
distribution of people in a given area over a period of
time This field, called demography, looks at changes in
population through birth rate, death rate, and migration from one place to another One major factor affecting where people live is a region’s type of economy In areas that depend on agriculture for their economy, people generally live in rural areas In places with an industrial economy, urban areas become major population centers
In 1950, 29% of the world’s population lived in urban areas In 1990, this figure increased to 43%
Today, more than half the world’s population—an estimated 6.2 billion—lives in Asia, with China and India
as major contributors The United States, the third most populous country in the world, makes up less than 5% of the global total

Trang 5ON T H E SO C I A L Studies Exam, you will read short passages, varying in length from 50 to 170
words, and then answer a multiple-choice question or set of questions concerning the passage Reading passages may be taken from a number of sources, often drawn from a workplace or aca-demic context The test uses both primary sources, such as firsthand historical or practical documents, and sec-ondary sources, such as excerpts from editorials, news articles, or news magazines
B e a n A c t i v e R e a d e r
When you read social studies material, you use a similar set of skills as you do when you read other kinds of text Reading is an active exercise in which you interact with the text, paying close to attention to the key thoughts and details of a passage Try skimming a passage first so that you can discern its organization and get clues about its main ideas If you read at a slow pace initially, you may lose the overall idea in too many details Look to see if a reading excerpt is broken into sections, if there are any helpful topic headings, and what key terms are boldfaced
or highlighted After you finish skimming, go back and read more closely This time ask yourself questions as you read to help you better understand and recall the passage: What is the main point of the text? How did the author support his or her point? As you read, consider making quick notes on a separate piece of paper to help you high-light important words or ideas

To show that you understand the concepts presented in
social studies material, the test will sometimes ask you to
find the main idea of a passage A main idea is a general
statement that contains all the ideas within a passage It
is an author’s main point
To locate a main idea, carefully read the topic sentence
of the passage The first sentence may contain the overall
idea that an author wishes to express However,
some-times an author may build up to his or her point, in
which case you may find the main idea in the last sentence
of the introductory paragraph or even the last sentence of
the entire passage Students often confuse the topic or
sub-ject of a passage—that is, what the passage is about—with
the main idea The main idea is what the author intends
to say about the subject For example, read the following
paragraph:
The fertile black soil of the Nile River Valley in
northeastern Africa gave rise to the
agriculture-based society of ancient Egypt For more than
3,000 years beginning as early as 5,000 B.C., this
civilization flourished Its cultural contributions
include basic concepts of arithmetic and
geome-try, a calendar, jewelry, pottery, statues, the
pyra-mids at Giza, underground burial chambers,
and the mummification process The Egyptian
script, called hieroglyphics, is a form of writing
based on pictures The Rosetta Stone, a granite
slab inscribed in 196 B.C with three identical
texts—two in hieroglyphic languages and one in
ancient Greek—aided scholars in deciphering
hieroglyphics
Note that a statement might be too general to best
describe the main idea of a passage For example, look at
the following choices Which best describes the main
idea of the selection?
a Early civilizations often developed near a
water source
b Before deciphering the Rosetta Stone, scholars
could not read Egyptian hieroglyphics
c Ancient Egypt was a sophisticated civilization
that made many contributions to human
culture
d The most important Egyptian contribution
was a written script called hieroglyphics
e Scholars have found similarities between
heiroglyphics and ancient Greek
Although choice a is a true statement, it is too general
to express the main idea of the paragraph Choice b is
also a true statement but is too specific to describe the
passage’s main idea Choice d is an opinion that is not supported by the details of the passage Choice e is not supported by the passage Choice c best describes the
paragraph’s main idea
To practice finding the main idea, ask yourself some of the following questions when you read:
■ What is this passage about?
■ What is the author’s purpose?
■ If you were asked to choose a headline or title for the passage, what would you choose?
■ Which sentence contains all the ideas expressed
in the passage?
F i n d i n g S u p p o r t i n g I d e a s
After you have highlighted the main idea of a passage, the next step is to find the details or facts that an author has provided to support his or her main position While a
main idea is a general statement, a supporting idea is spe-cific information For example, read the next paragraph
from a U.S Census Bureau report:
The growth of human population has been, is now, and in the future will be almost entirely determined in the world’s less developed coun-tries (LDCs) Ninety-nine percent of global nat-ural increase—the difference between numbers
of births and numbers of deaths—now occurs
in the developing regions of Africa, Asia, and Latin America
The topic of this paragraph is world population The
main idea of the passage is what the writer is saying about
world population In this case, the first sentence
expresses the main idea: The growth of human population has been, is now, and in the future will be almost entirely determined in the world’s less developed countries (LDCs).
The next sentence offers specific information that
Trang 7supports the main idea It offers a specific fact in the
form of a statistic (ninety-nine percent of global natural
increase) and gives details about which areas of the world
the passage is talking about (developing regions of Africa,
Asia, and Latin America).
These words and phrases are often used to introduce
a detail or idea that supports an author’s position:
for example for instance
one reason is in one case
in particular specifically
To practice locating supporting ideas while you read,
skim the text and look for the following:
■ examples that bolster the main idea
■ contrasting arguments that clarify the author’s
point
■ arguments for the author’s position
■ details that answer what, when, where, why,
or how
R e s t a t i n g I n f o r m a t i o n
The GED Social Studies Test will ask you to answer
ques-tions based on details supplied in a passage However, the
answer choices will not present the details in the same
words—they may restate the information in different
terms To strengthen your critical thinking skills, when
you are reading, pause and think about what the
mate-rial is stating Then try putting it in your own words
This will help you better understand reading material
and increase your ability to recognize the same material
even if it is written in new terms For example, read the
following passage:
The North American Free Trade Agreement
(NAFTA) is an agreement between Canada,
Mexico, and the United States to remove tariffs
and trade barriers from goods made and sold in
the continent Before the pact was approved in
1993, lawmakers and special-interest groups
fiercely debated the issue Labor groups believed
that NAFTA would make it easier for U.S
busi-nesses to move their production plants to
Mex-ico to take advantage of cheap labor
Environmental groups opposed NAFTA because they felt that pollution regulations would be more difficult to enforce
Think about how you would rephrase this informa-tion in your own words Now answer the practice question
According to the information in the paragraph, which
of the following is true?
a Supporters of NAFTA were not challenged.
b Opponents of NAFTA wanted to keep duties
and other tariffs on U.S goods shipped to Mexico
c Labor groups were afraid that U.S jobs would
be lost
d Canada and the United States never approved
NAFTA
e Labor groups believe it is cheaper to produce
goods in the United States
Choice c is correct It restates the following sentence
from the passage: “Labor groups believed that NAFTA would make it easier for U.S businesses to move their plants to Mexico to take advantage of cheap labor.”
Choices a and d are incorrect statements Choice b may
be true, but it is not mentioned in the paragraph
M a k i n g I n f e r e n c e s
While restating information tests your ability to know
what a text says, making inferences about a passage demonstrates your ability to know what a text means.
Sometimes, an author may not explicitly state his or her main idea or offer a conclusion You must infer the
author’s meaning Being able to make inferences is an
important critical thinking skill To figure out an
unstated idea or conclusion, look at what the author has
stated Ask yourself these questions:
■ What can I conclude based on the information provided?
■ What is the author suggesting?
■ What will be the outcome?
■ Would the same outcome occur in another setting?

Trang 8Read the following excerpt from Elizabeth Cady
Stan-ton’s paper, “Government the Best Means of
Self-Development,” which she presented to the U.S Senate
Committee on Woman Suffrage at a March 7, 1884
hear-ing Then answer the practice question
“They who say that women do not desire the
right of suffrage, that they prefer masculine
domination to self-government, falsify every
page of history, every fact in human experience
It has taken the whole power of the civil and
canon law to hold woman in the subordinate
position which it is said she willingly accepts.”
What is the author of this passage suggesting?
a Women do not want the right to vote.
b Women need to have access to education
before they are allowed the right to vote
c Lawmakers and religious leaders have been
coercive in maintaining women’s status as
“second-class” citizens
d Women can still be influential citizens
with-out the right to vote
e Women willingly accept their subordinate
position
Statements a, d, and e are incorrect Elizabeth Cady
Stanton is making a counterargument against the
posi-tion that women do not want the right to vote Statement
b is not supported by the details given in the passage.
Statement c is the best answer Stanton uses strong
lan-guage to make her argument for women’s suffrage She
says that “canon law,” which refers to the laws of the
Christian Church, and “civil law,” which refers to the laws
of the United States, have used their power to keep
women in a “subordinate position.”
Looking for Proof
Just because something is in print does not mean that the
reader must believe it or take it as fact Most written
material has some bias Sometimes, a writer’s beliefs may
unknowingly affect how he or she writes about an event
In other instances, a writer purposefully tries to shape
your reaction and opinion For example, a writer may
present only one perspective of an event or include only
facts that support his or her position One crucial
think-ing skill that the GED will measure is your ability to
make judgments about what you read As you read, you
will need to challenge the author’s assumptions and posi-tions, tell the difference between fact and opinion, and look for complete and accurate information
F ACT VS O PINION
A fact is a statement that can be verified by a reliable
source Because all sources have some bias, you must decide whether you think a source presents accurate, researched information Examples of reliable sources of information may include official government docu-ments, encyclopedias, or well-documented studies Here
is an example of a factual statement:
The U.S population is growing older—in fact, adults over age 65 are the fastest-growing seg-ment of today’s population
This sentence could be supported by the recent national census
An opinion is a statement of the beliefs or feelings of
a person or group It cannot be proven by a reliable source An opinion is a judgment that may or may not
be true It includes predictions of the future because it cannot be proven at the current time The following sen-tence represents an opinion:
Many believe that the population boom among elderly Americans will create a future health-care crisis
Note that this statement is attributed to a source (“many”) that is unknown and therefore cannot be ver-ified It also represents a belief or speculation about the future Others may disagree with this prediction
Be alert to the common words that may introduce a statement of opinion:
likely should/could say
probably believe attest
E MOTIONAL L ANGUAGE
Propaganda refers to techniques that try to influence
your opinion, emotions, and attitudes in order to bene-fit an organization or individual Propaganda uses lan-guage that targets your emotions—your fears, beliefs, values, prejudices—instead of appealing to reason or critical thinking Advertising, media, and political
Trang 9cam-paigns use propaganda techniques to influence you To
detect propaganda, ask yourself the following questions
about written material:
■ Who does it benefit?
■ What are its sources?
■ What is the purpose of the text?
Here are six common propaganda techniques:
Bandwagon—The basic message of bandwagon
propaganda is “everyone else is doing something, so
you should be, too.” It appeals to the desire to join
the crowd or be on the winning team Phrases like
“Americans buy more of our brand than any other
brand” or “the brand that picky parents choose” are
examples of the bandwagon technique To evaluate a
message, ask these questions:
■ Does this program or policy serve my particular
interests?
■ What is the evidence for or against it?
Common Man—This approach tries to convince
you that its message is “just plain old common
sense.” Politicians and advertisers often speak in an
everyday language and use common jokes and
phrases in order to present themselves as one “of the
people,” and thereby appeal to their audience For
example, a presidential candidate campaigning in
New Hampshire may dress in a plaid shirt and chop
wood or visit a mill in order to look like an ordinary
citizen To avoid the common-man technique, ask
yourself these questions:
■ What ideas is the person presenting—separate
from the person’s image or language?
■ What are the facts?
Euphemisms—Instead of emotionally loaded
lan-guage that rouses its audience, these terms “soften”
an unpleasant reality and make it less emotional
Terms that soften the nature of war are an example
A historical instance of euphemism is when in the
1940s, the U.S government renamed the War
Department to the Department of Defense Stay
alert to euphemisms What facts are being softened
or hidden?
Generalities—This approach uses words and
phrases that evoke deep emotions Examples of
gen-eralities are honor, peace, freedom, or home These
words carry strong associations for most people By using these terms, a writer can appeal to your emo-tions so that you will accept his or her message with-out evaluating it Generalities are vague so that you will supply your own interpretations and not ask further questions An example might be, “The United States must further restrict immigration in order to preserve freedom and liberty.”
Try to challenge what you read or hear Ask yourself:
■ What does the generality really mean?
■ Has the author used the generality to sway my emotions?
■ If I take the generality out of the sentence, what are the merits of the idea?
Labeling or name calling—This method links a
negative label, name, or phrase to a person, group, belief, or nation It appeals to hates and fears Name calling can be a direct attack or it can be indirect, using ridicule Labels can evoke deep emotions, such
as Commie, Nazi, or Terrorist Others can be nega-tively charged, depending on the situation: Yuppie, Slacker, Liberal, or Reactionary When a written text
or speech uses labeling, ask yourself these questions:
■ Does the label have any real connection to the idea being presented?
■ If I take away the label, what are the merits of the idea?
Testimonials—In advertising, athletes promote a
range of products, from cereal to wristwatches In politics, celebrities endorse presidential candidates Both are examples of testimonials A testimonial uses a public figure, expert, or other respected per-son to endorse a policy, organization, or product Because you may respect or admire a person, you may be less critical and accept a product, candidate,
or idea more readily Ask yourself these questions:
■ Does the public figure have any expert knowledge about this subject?
■ Without the testimonial, what are the merits of the message?

Trang 10O NLY H ALF THE S TORY
Another way a writer may slant information is to omit
evidence A writer may try to convince you to accept his
or her interpretation of an event or issue by giving you
only one side of the story and by leaving out contrasting
facts or perspectives When this is done deliberately, it is
a propaganda technique called card stacking When you
read, evaluate whether the author has presented different
points of view and offered balanced evidence For
instance, a campaign ad might highlight a candidate’s
positive qualities and leave out unfavorable
characteris-tics Campaign ads might also target an opponent,
pre-senting negative qualities and omitting positive ones,
thereby creating a distorted perspective
C a u s e a n d E f f e c t R e l a t i o n s h i p s
The GED Social Studies Test will ask you to identify the
relationships between events Often, historical events are
connected to situations that came before them When
you are considering the causes of an event, be aware that
multiple causes can create one effect, just as one cause
can have many effects Sometimes, what is considered a
cause can be controversial In the following passage,
leg-islators and criminologists argue over the causes that
might have contributed to a drop in the youth crime rate
Juvenile crime has reached its lowest national
level since 1988 The number of arrests for
juve-nile murder has also dropped It is now at the
lowest level since 1966 Backers of “adult time”
legislation—“get-tough” laws that send violent
teenagers to adult prison—believe that fear of
imprisonment is stopping juveniles from
com-mitting crimes However, the decrease in crime
often started before these laws took effect Some
criminologists believe a drop in crack cocaine use and gun carrying is the more likely cause These experts argue that as the crack market dropped off in the mid-1990s, fewer teens were dealing drugs and fewer were carrying guns to protect themselves Police also increased their efforts to enforce gun laws With fewer young people carry-ing weapons, the teen murder rate dropped
According to the criminologists mentioned in the pas-sage, which of the following is NOT a cause of the drop
in juvenile crime?
a fewer gun-carrying juveniles
b enforced gun laws
c fear of jail time
d fewer drug dealers on the street
e police presence
The correct choice is c In the passage, criminologists
argue that “adult time” laws have not had an effect on the
decrease in youth crime They believe that choices a, b, d, and e are multiple causes of the drop in crime.

As with any type of study, the social sciences use specific terms and vocabulary While you are studying for the test, use a dictionary to look up unfamiliar terms How-ever, even if you do not recognize a word, you might
be able to figure out its meaning The parts of a word—
prefix, root, and suffix—can offer clues to its meaning A number of terms used in social studies derive from Latin
or Greek Knowing some useful word parts can help you make an educated guess about the meaning of a word Review these common Latin and Greek word parts:
