Recent History, Global Connections & Citizenship — Chapter Practice, Grade 8
Study four focused units, then compare evidence in the chapter workshop, complete the review, and take the quiz.
Problem 1
Answer and explanation
Yes. If prices rise faster or hours fall, purchasing power or total income can decline despite a higher hourly wage.
Problem 2
Answer and explanation
Higher productivity or automation may allow fewer workers to produce more. Employment and output measure different outcomes.
Problem 3
Answer and explanation
A defined outcome, baseline, time period, implementation evidence, and comparison with other influences. A slogan or intention is insufficient.
Problem 4
Answer and explanation
They help distinguish changes in purchasing power from changes in dollar amounts. State the adjustment and remaining differences in households or prices.
Problem 5
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.
Response criteria
- Describe the historical context and institutions accurately.
- Use relevant evidence and explain how it supports the claim.
- Represent perspectives without stereotypes or invented testimony.
- Identify a limitation, counterevidence, or information still needed.
Problem 6
Answer and explanation
It shows those changes coincided; inspect staffing, hours, demand, investment, and decisions before assigning the whole employment change to automation.
Response criteria
- Describe the historical context and institutions accurately.
- Use relevant evidence and explain how it supports the claim.
- Represent perspectives without stereotypes or invented testimony.
- Identify a limitation, counterevidence, or information still needed.
Problem 7
Answer and explanation
Materials, components, design, transport, and services may come from many places. The label describes a particular classification, not every contribution.
Problem 8
Answer and explanation
It omits reliable service, affordability, skills, language, and accessibility. Effective use depends on more than owning hardware.
Problem 9
Answer and explanation
No. Repetition can follow the same origin. Independent evidence and context establish reliability, not the share count.
Problem 10
Answer and explanation
They may prioritize different outcomes or time horizons. Each should accurately describe evidence, explain trade-offs, and acknowledge relevant counterevidence.
Problem 11
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.
Response criteria
- Describe the historical context and institutions accurately.
- Use relevant evidence and explain how it supports the claim.
- Represent perspectives without stereotypes or invented testimony.
- Identify a limitation, counterevidence, or information still needed.
Problem 12
Answer and explanation
Find the original data and definitions, check the date and method, and seek independent evidence. Duplicate graphics may have only one source.
Response criteria
- Describe the historical context and institutions accurately.
- Use relevant evidence and explain how it supports the claim.
- Represent perspectives without stereotypes or invented testimony.
- Identify a limitation, counterevidence, or information still needed.
Problem 13
Answer and explanation
The perpetrators are particular actors. Shared religious identification does not establish support, responsibility, or identical beliefs among millions of people.
Problem 14
Answer and explanation
A decision may rely on claims that later evidence contradicts. Historical analysis records both what was asserted and what subsequent investigation established.
Problem 15
Answer and explanation
It omits lending incentives, financial institutions, risk transfer, regulation, and interconnected markets. Explain the system’s mechanisms as well as household decisions.
Problem 16
Answer and explanation
Use consistent evidence and reasoning criteria. A student need not agree with the instructor’s preference when the response is accurate, supported, and acknowledges trade-offs.
Problem 17
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.
Response criteria
- Describe the historical context and institutions accurately.
- Use relevant evidence and explain how it supports the claim.
- Represent perspectives without stereotypes or invented testimony.
- Identify a limitation, counterevidence, or information still needed.
Problem 18
Answer and explanation
It assigns collective responsibility without evidence of individuals’ actions or support. Identify the documented actors and avoid generalization from membership in a broad community.
Response criteria
- Describe the historical context and institutions accurately.
- Use relevant evidence and explain how it supports the claim.
- Represent perspectives without stereotypes or invented testimony.
- Identify a limitation, counterevidence, or information still needed.
Problem 19
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.
Problem 20
Answer and explanation
Yes. Different priorities, assumptions, or acceptable trade-offs can lead to different recommendations. Explain them rather than treating preference as proof of factual ignorance.
Problem 21
Answer and explanation
It tests the claim’s limits and prevents cherry-picking. A stronger explanation responds to relevant evidence or revises its scope.
Problem 22
Answer and explanation
Historical accuracy, relevant evidence, explanation, fair treatment of alternatives, and limitations—not identity, family background, political agreement, or confidence speaking.
Problem 23
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.
Response criteria
- Describe the historical context and institutions accurately.
- Use relevant evidence and explain how it supports the claim.
- Represent perspectives without stereotypes or invented testimony.
- Identify a limitation, counterevidence, or information still needed.
Problem 24
Answer and explanation
Accuracy, source relevance, reasoning, trade-offs, and counterevidence. Disagreement with the parent’s preference is not itself an error.
Response criteria
- Describe the historical context and institutions accurately.
- Use relevant evidence and explain how it supports the claim.
- Represent perspectives without stereotypes or invented testimony.
- Identify a limitation, counterevidence, or information still needed.
