Recent History, Global Connections & Citizenship — 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
Economic Change Since the 1970s: Work, Policy & Distribution
Governments and voters debated taxes, regulation, spending, monetary policy, unions, and trade. This lesson studies historical proposals and evidence; it does not recommend a party or present current policy as settled. Distinguish policy aims, implementation, and outcomes.
Globalization, Technology & Unequal Connection
Connections can expand markets and knowledge while exposing communities to disruption and uneven power. The effects depend on institutions, infrastructure, work, and access. Evaluate a specific supply chain or technology instead of assuming all connection is either beneficial or harmful.
The Early Twenty-First Century: Security, Crises & Public Decisions
This lesson examines documented historical events and decision-making tools rather than supplying a constantly updated news feed. For a present-day question, check current primary records and dates. Distinguish established facts, interpretations, predictions, and policy preferences.
Citizenship, Public Evidence & a History Capstone
A capstone brings together chronology, sourcing, causation, comparison, continuity, and change. It should demonstrate a reasoned historical explanation and acknowledge limits. The goal is informed inquiry, not a required national pride, guilt, or political conclusion.
Problem 1
Answer and explanation
The model suggests purchasing power fell about 4.3% despite a nominal raise. It does not establish every worker’s experience or the cause of inflation; hours, expenses, and the index’s scope must be checked.
Pay rises 10%; the index rises 15%. Relative purchasing power is 1.10/1.15, about 0.957 of its starting level. A household’s actual purchases may differ from the index basket.
Problem 2
Answer and explanation
Yes. If prices rise faster or hours fall, purchasing power or total income can decline despite a higher hourly wage.
Problem 3
Answer and explanation
Cheaper goods and lost jobs can both be documented without contradiction. A broader judgment requires distribution and conditions across the chain, not an assumption that one price establishes everyone’s welfare.
Map distinct stages and participants. Separate consumer prices from employment outcomes. Ask about wages, working conditions, environmental effects, and adjustment support.
Problem 4
Answer and explanation
Materials, components, design, transport, and services may come from many places. The label describes a particular classification, not every contribution.
Problem 5
Answer and explanation
A program can improve lending while unemployment remains high. The claims measure different parts of a crisis. Evaluation requires timing and methods, plus evidence about indirect effects and who benefited.
Distinguish bank stability, lending, and employment as separate outcomes. Request dates, measures, eligibility, and survey methods. Avoid using one outcome to declare universal success or failure.
Problem 6
Answer and explanation
The perpetrators are particular actors. Shared religious identification does not establish support, responsibility, or identical beliefs among millions of people.
Problem 7
Answer and explanation
For voting access, a provisional claim might explain how constitutional guarantees required later organization and enforcement. A timeline could include 1870, a documented registration barrier, and 1965. The plan should compare legal text with implementation evidence and avoid treating every region or decade identically.
Choose a question with a defined period and institution. Select relevant evidence and explain why it supports the claim. Identify counterevidence and a condition that would require revision.
Problem 8
Answer and explanation
The institution’s authority and process determine which actions are possible. A proposal directed to the wrong body may not address the problem.
