College Board assigns Unit 7 · Global Conflict 8–10% of AP World History: Modern multiple-choice questions; this is not a percentage of the total exam score.

Alliance decisions, imperial rivalry, nationalism, economic disruption, expansionist ideology, and state mobilization turned regional crises into global wars whose burdens fell on soldiers, civilians, colonized populations, and targeted communities.

  • Lens world wars, interwar crisis, and mass violence after 1900
  • Regions Europe, East Asia, Africa, the Middle East, the Pacific, and colonial theaters
  • Decision Which causal structure avoids reducing World War I to the assassination at Sarajevo?

Unit 7 · Global Conflict evidence decision

Read each question as it appears on the exam paper, choose your answer, then tap it to see the feedback.

Practice 1: Use two clocks for World War I

Q. Which revision distinguishes long-run conditions from decisions that escalated the immediate crisis? Read the exam question below, choose one option, then tap it to check.
SECTION I · MULTIPLE CHOICE · QUESTION 1

A student argues that the assassination at Sarajevo alone caused World War I.

Which revision best creates a defensible causal explanation?

A. Describe the assassination in greater detail and conclude that war followed automatically.

❌ Not quite 😭 More detail about the trigger does not explain why a regional crisis expanded. Treating war as automatic removes the choices made by states and alliances.

B. Connect alliance systems, imperial rivalry, and militarization to the later decisions that widened the Sarajevo crisis, then rank their importance.

✅ Correct! 😊 This combines the slow buildup with the fast sequence of escalation. Ranking the factors produces a causal judgment rather than a list.

C. List wartime propaganda, food controls, and civilian suffering as the causes of the war.

❌ Not quite 😭 These examples concern how total war was conducted after conflict began. They cannot replace evidence explaining the outbreak.

D. Use the eventual peace settlement to prove that prewar conflict was inevitable.

❌ Not quite 😭 A later settlement cannot determine earlier causation. This hindsight obscures alternatives and decisions available during the crisis.

Full explanation
  • Step 1Separate the assassination as an immediate trigger from conditions already making crisis dangerous.
  • Step 2Identify long-run factors such as alliances, imperial competition, nationalism, and militarization.
  • Step 3Trace state decisions that activated alliances and widened the conflict.
  • Step 4Rank the factors and explain why a rival cause had less reach.
Answer. B. Connect alliance systems, imperial rivalry, and militarization to the later decisions that widened the Sarajevo crisis, then rank their importance.
Model answer. Limit the claim, compare long-run conditions with immediate escalation decisions, and explain the institutional mechanism that turned a regional crisis into global war.
Scoring guideline. The strongest answer establishes a multicausal line of reasoning, distinguishes conditions from escalation decisions, and makes a defensible causal judgment.

Practice 2: Separate causes from total-war conduct

Q. Which plan answers the source while keeping conduct distinct from causation? Read the exam question below, choose one option, then tap it to check.
SECTION II · FREE RESPONSE · QUESTION 13 points

A source describes a wartime government directing factories, rationing food, using propaganda, and recruiting soldiers from colonies.

(a) Identify the broader form of warfare reflected in the source. (b) Explain one way state mobilization expanded the war's social reach. (c) Explain why this evidence does not by itself establish a cause of the war.

A. Identify total war, explain how mobilization drew workers and colonial populations into conflict, and state that wartime measures followed rather than caused the outbreak.

✅ Correct! 😊 This accurately classifies the source, explains its social reach, and respects chronology. It uses the evidence for conduct without misusing it as a cause.

B. Identify nationalism, repeat that citizens supported war, and call propaganda the sole cause.

❌ Not quite 😭 The source depicts broad mobilization, not nationalism alone. Propaganda during war cannot by itself explain why states entered the conflict.

C. Describe battlefield tactics and ignore factories, food, finance, and colonial recruitment.

❌ Not quite 😭 This narrows total war to combat and misses the source's main evidence. The social and economic mobilization is precisely what expanded the conflict's reach.

D. List alliance systems for all three parts without using the source.

❌ Not quite 😭 Alliances may help explain outbreak, but they do not identify the wartime system shown. The response must distinguish the source's subject from a separate causal argument.

Full explanation
  • Step 1Classify the coordinated economic and social measures as total war.
  • Step 2Explain how state mobilization drew labor, food, finance, propaganda, colonies, and civilians into warfare.
  • Step 3Use the colonial soldier or factory worker as evidence of expanded social reach.
  • Step 4Preserve chronology: conduct after war began cannot alone explain the initial outbreak.
Answer. A. Identify total war, explain how mobilization drew workers and colonial populations into conflict, and state that wartime measures followed rather than caused the outbreak.
Model answer. (a) The source reflects total war because the state mobilized economic and civilian resources for conflict. (b) Factory direction, rationing, propaganda, and colonial recruitment expanded the war beyond soldiers by involving workers, households, and colonized populations. (c) These policies show how war was conducted after fighting began, so they cannot by themselves explain the earlier conditions and decisions that caused the outbreak.
Scoring guideline. Each part must identify accurate evidence, explain its relationship to total-war mobilization, and distinguish wartime conduct from causes of conflict.
