13.3 U.S. History Cause, Effect, and Change

History Questions Ask What Changed and Why

U.S. history is about 20 percent of the Social Studies test, but the exam is not built around memorizing dates. It uses history to measure reasoning: sequence events, identify causes, compare interpretations, and decide what evidence supports a conclusion. The official content topics span the Revolutionary and Early Republic periods, westward expansion and U.S. Indian policy, the Civil War and Reconstruction, the civil rights era, immigration and settlement, the world wars, the Cold War, and American foreign policy since 9/11.

A strong history reader asks two questions on every stimulus: What happened first, and why did it matter?

Cause, Effect, Continuity, Change

The American Revolution combined ideas about rights and consent, economic disputes such as the Stamp Act and Tea Act, colonial self-government, and conflict with Parliament. The Civil War combined slavery, sectionalism, political conflict, economic differences, and disputes over federal versus state power. The civil rights movement combined constitutional arguments, organized protest, court decisions like Brown v. Board of Education (1954), federal action such as the Civil Rights Act of 1964, and local resistance.

High-Yield Historical Patterns and Evidence Rules

Certain eras generate predictable GED items. Learn the through-lines:

• Reconstruction (1865-1877): connects the Civil War's aftermath to the 13th, 14th, and 15th Amendments, federal enforcement, and the rise of Jim Crow laws after federal troops withdrew.
• Industrialization and the Gilded Age: links new technology (railroads, steel, electricity), immigration, urban growth, labor unions, and concentrated business power.
• World Wars: connect alliances, nationalism, economic pressure, totalitarian governments, civil-liberties limits (such as wartime censorship and Japanese American internment), and postwar institutions like the United Nations.
• Cold War (1947-1991): contrasts capitalism and communism through containment, the Marshall Plan, NATO, the arms race, and proxy conflicts in Korea and Vietnam.

The GED usually supplies the needed facts in the stimulus; your job is to use them accurately.

Source-Analysis Routine

1. Identify the time period and topic before reading the answer choices.
2. Mark sequence words: before, after, as a result, because, led to, during, however.
3. Separate background conditions from direct causes.
4. Look for more than one cause when the source names several forces.
5. Choose the effect that follows from the evidence and fits the time period.

If a source says factories expanded as railroads linked regions and immigrants supplied labor, the best answer names more than one factor. If a court ruling changed school segregation, do not pick an answer about World War I unless the stimulus connects them.

Evaluating Historical Claims

GED history items often include a historian's claim, a primary-source excerpt, or a data display. Ask whether the evidence is strong enough:

• A single diary entry shows one person's experience but cannot prove what everyone believed.
• A government report offers official data but may reflect the issuing agency's priorities.
• A political speech reveals goals and arguments but may omit inconvenient facts.

The safest answers use moderate language: suggests, contributed to, helped cause, is evidence of. Be wary of proved, only, always, and never. History involves many people, ideas, and conditions, so the best GED answer usually recognizes complexity while staying anchored to the source.

Comparing Interpretations

Some history items show two historians or two sources that explain the same event differently — for instance, one arguing the Civil War was mainly about slavery and another emphasizing states' rights and economics. The GED rarely asks you to pick the "true" interpretation; it asks what each writer claims, what evidence each uses, or where they agree and disagree. Treat the two views as overlapping rather than mutually exclusive: most major events have several real causes, so an answer that lets both factors coexist usually beats one that forces a single explanation.

Turning Points to Know

A handful of turning points recur because they redirected American history, and recognizing them speeds up cause-and-effect items: the Declaration of Independence and the Revolution; the ratification of the Constitution; the Louisiana Purchase and westward expansion; the Civil War and the abolition of slavery; the New Deal's expansion of federal economic power during the Great Depression; the United States entering World War II after Pearl Harbor; Brown v. Board of Education and the civil rights movement; and the end of the Cold War.

You do not need exact dates for most items, but you should be able to place these events in order and explain, in one sentence each, what changed because of them.
