Industrial Growth, Corporations & the Gilded Age — Practice · Grade 8 Social Studies

Chapter: Industry, Migration & Urban Life

What this practice covers

By the end of Industrial Growth, Corporations & the Gilded Age you should be able to:

6 questions, written answer, each with a worked explanation.

Vocabulary used: context, corroboration, interpretation, vertical integration, horizontal integration.

Problem 1

Why is industrial growth not explained by one inventor?
Answer and explanation

It required resources, workers, investment, markets, transport, and institutions as well as inventions. A useful explanation connects these factors through mechanisms.

Problem 2

If a steel company buys an ore mine, which integration strategy is illustrated?
Answer and explanation

Vertical integration: the company joins a supply stage to production. Buying another steel producer would instead illustrate horizontal integration.

Problem 3

Can lower prices and dangerous working conditions both be true?
Answer and explanation

Yes. They concern different outcomes and groups. Assess production, consumption, labor conditions, and distribution separately before making an overall judgment.

Problem 4

What evidence could test a claim that a merger benefited consumers?
Answer and explanation

Compare prices, quality, access, and alternatives before and after, accounting for other changes. The company’s assertion alone does not establish a consumer benefit.

Problem 5

Illustrative classroom figures: a firm’s daily output grows from 100 to 160 units, while the workday falls from 12 to 10 hours. A worker account reports a new machine-related injury risk. Calculate output per scheduled hour and explain why the figures cannot alone establish improved worker welfare.
Answer and explanation

Scheduled output per hour rises in this example. A shorter day is one changed condition, but injury risk and pay require separate evidence. We cannot attribute the whole increase to a machine without knowing staffing and other changes.

Before: 100/12 is about 8.3 units per hour; after: 160/10 is 16.

Higher output per hour suggests changed production, not automatically higher pay or safety.

Seek wage, injury, staffing, and product-quality records.

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

An oil refiner purchases competing refineries and its own delivery fleet. Identify the two strategies and one question about competition.
Answer and explanation

Purchasing competitors is horizontal integration; owning delivery is vertical integration. Ask whether entry, prices, or alternative suppliers changed.

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.
