Recent History, Global Connections & Citizenship — Chapter quiz · U.S. History: Reconstruction to the Early 21st Century, Grade 8

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

Problem 1

What is needed to test a claimed policy benefit?
Answer and explanation

A defined outcome, baseline, time period, implementation evidence, and comparison with other influences. A slogan or intention is insufficient.

Problem 2

A company raises output and cuts jobs after adding machines. What does this show and what does it not establish?
Answer and explanation

It shows those changes coincided; inspect staffing, hours, demand, investment, and decisions before assigning the whole employment change to automation.

Problem 3

Does a widely shared post become reliable because many people repeat it?
Answer and explanation

No. Repetition can follow the same origin. Independent evidence and context establish reliability, not the share count.

Problem 4

Two websites use the same uncited graph. What should a learner do before treating them as corroboration?
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.

Problem 5

Why is “people borrowed too much” an incomplete crisis explanation?
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 6

A post blames all followers of a religion for an attack by one organization. Explain the evidentiary error.
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.

Problem 7

Why include evidence that challenges a claim?
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 8

A student gives a well-supported policy recommendation different from the parent’s preference. What should marking consider?
Answer and explanation

Accuracy, source relevance, reasoning, trade-offs, and counterevidence. Disagreement with the parent’s preference is not itself an error.
