World War I, the 1920s & Depression — Problem set, Grade 8

Study four focused units, then compare evidence in the chapter workshop, complete the review, and take the quiz.

Review the key ideas

World War I: Causes, U.S. Entry & Peace

The United States initially remained formally neutral, though trade and public opinion were uneven. In 1917 unrestricted submarine warfare and the Zimmermann Telegram contributed to entry. Mobilization, restrictions on dissent, and peace negotiations then raised questions about democracy, security, and international cooperation.

The 1920s: Consumer Culture, Conflict & Uneven Prosperity

The period also included the Harlem Renaissance, immigration restrictions, Prohibition, religious and cultural disputes, and racial violence. Change and exclusion existed together. Study particular institutions and choices rather than dividing society into two uniform camps.

The Great Depression: Causes & Everyday Consequences

Unemployment and lost savings affected housing, food, families, and migration. Experiences varied across communities and regions. Government responses developed over time; Hoover’s administration did take measures, while Roosevelt’s New Deal expanded and changed federal action after 1933.

The New Deal: Programs, Debate & Unequal Access

Supporters and critics disagreed about constitutional authority, cost, dependency, business conditions, and the scale of relief. Some wanted less intervention; others demanded more or broader inclusion. Evaluate programs individually, using their goals, implementation, and effects.

Problem 1

Teaching summaries: U.S. leaders cite shipping attacks in early 1917; the Zimmermann Telegram proposes an alliance; trade links and security concerns already exist. Explain two contributing mechanisms and why the telegram alone is an incomplete explanation of U.S. entry.
Answer and explanation

Shipping attacks threatened lives and commerce; the telegram intensified fears about security. These pressures interacted with earlier relationships and political choices. Additional records are needed to weigh their relative importance.

Identify threats to shipping and perceived security. Connect the telegram to existing pressures rather than replacing them. Distinguish a public justification from a complete account of motives.

Problem 2

Why is a list of causes weaker than a causal explanation?
Answer and explanation

A list names factors but does not show how they interacted or affected decisions. Explain the mechanism and sequence supported by evidence.

Problem 3

Illustrative classroom budget: monthly income is $100, necessary expenses $85, and an installment payment $10. Income later falls to $90 while the obligations remain. Calculate the balance before and after the income fall. Explain how a consumer purchase and financial vulnerability can coexist.
Answer and explanation

The payment initially fits the stated budget but leaves little reserve. The later income fall creates a shortfall. This illustrates a credit mechanism, not a claim that all 1920s households had this budget or that this alone caused the Depression.

Initially $100−$85−$10 leaves $5. Afterward $90−$85−$10 leaves a $5 shortfall. Explain that fixed obligations can become difficult after an income change.

Problem 4

Why does an advertisement not establish widespread affordability?
Answer and explanation

It aims to persuade. Income, prices, loan terms, and purchase records are needed to show who could buy and what debts followed.

Problem 5

Teaching scenario: a bank closes, families lose access to savings, local purchases fall, and shops reduce staff. Other banks and public relief are not described. Explain the mechanism connecting the bank closure to employment and identify evidence needed to establish its size or wider reach.
Answer and explanation

The sequence supplies a plausible reinforcing contraction. It does not establish that every closure produced the same outcome or that one bank caused a national depression. Local sales and employment records could test the proposed chain.

Lost access to funds can reduce household spending. Lower sales can lead shops to reduce work and wages. Compare timing, alternative credit, relief, and records from other places.

Problem 6

Why does the crash alone not explain the whole Depression?
Answer and explanation

It does not describe banking failures, credit contraction, spending, international pressures, or policy responses. Explain how these affected production and employment.

Problem 7

Illustrative policy comparison: plan A provides temporary cash to eligible households; plan B hires some unemployed adults to build public facilities. Both have limited budgets, and eligibility rules are unspecified. Explain a benefit and a limitation of each, then identify information required to compare access fairly.
Answer and explanation

Neither label establishes universal superiority. The designs address different needs and constraints. A justified comparison needs access rules, costs, timing, and evidence of household outcomes; accept different priorities when the reasoning is explicit.

Cash can meet varied immediate needs but depends on eligibility and benefit size. Jobs provide earnings and infrastructure but may exclude people unable to take the work. Compare budgets, coverage, administration, and local need.

Problem 8

Why might one project fit more than one category?
Answer and explanation

A project can pay unemployed workers now, stimulate demand, and build infrastructure. Identify each mechanism instead of forcing it into only one label.
