Market & Industrial Change: Production, Labor & Technology — Practice · Grade 7 Social Studies

Chapter: Early Republic, Markets & Migration

What this practice covers

By the end of Market & Industrial Change: Production, Labor & Technology you should be able to:

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

Vocabulary used: context, primary source, interpretation, industrialization, productivity.

Problem 1

Does higher output per hour prove every worker earns more?
Answer and explanation

No. Pay, ownership, hours, conditions, and bargaining power affect distribution. A productivity measure does not establish all these outcomes.

Problem 2

Why did a cotton-cleaning machine not automatically end slavery?
Answer and explanation

It altered one stage and increased profitability under growing demand. Land, cultivation labor, ownership, law, and enforcement shaped expansion of enslaved labor.

Problem 3

How can two harsh work settings still involve different institutions?
Answer and explanation

Legal status, ability to leave, ownership of earnings, heredity, and enforceable rights can differ. Compare those conditions as well as hours and pay.

Problem 4

What would improve comparison of two wage claims?
Answer and explanation

Use dated payroll, work hours, job definitions, deductions, and independent worker accounts instead of compare unqualified totals.

Problem 5

Invented factory model: before a change, 10 workers each work 8 hours to produce 80 items; afterward, 10 each work 8 hours to produce 120. Pay and safety are unknown. Calculate items per worker-hour and explain what the record cannot show.
Answer and explanation

Productivity rises from 80/80=1 item to 120/80=1.5 items per worker-hour, a 50% increase under the model. Work hours remain unchanged in the supplied record. Pay, safety, job security, and the distribution of gains are unknown; these invented totals do not establish universal wellbeing.

Compute 80 worker-hours in each case.

Divide output by worker-hours.

Keep productivity separate from pay and conditions.

Response criteria

  • Describe the historical context and institutions accurately.
  • Connect relevant evidence with an explained claim or calculation.
  • Represent particular perspectives without stereotypes or invented testimony.
  • Identify an assumption, evidentiary limit, or distinction that qualifies the conclusion.

Problem 6

An advertisement says a machine saves labor. What should a historian ask next?
Answer and explanation

Which task and input does it reduce, under what conditions, and how do production volume, other tasks, wages, coercion, and demand change? A slogan does not establish all consequences.

Response criteria

  • Describe the historical context and institutions accurately.
  • Connect relevant evidence with an explained claim or calculation.
  • Represent particular perspectives without stereotypes or invented testimony.
  • Identify an assumption, evidentiary limit, or distinction that qualifies the conclusion.

Problem 7

What task does a cotton gin perform?
Answer and explanation

It separates cotton fibers from seeds; it does not itself plant or harvest the crop.

Problem 8

Why use worker-hours instead of only worker totals?
Answer and explanation

Worker-hours account for time as well as number. A change in hours can alter input even when worker count stays the same.
