Industry, Migration & Urban Life — 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

Industrial Growth, Corporations & the Gilded Age

A corporation pools investment and organizes a business under a legal structure. Large firms could produce more cheaply through scale and coordination, while concentrated economic power could weaken competition and bargaining. Evaluate both mechanisms with evidence instead of assuming every large firm had identical effects.

Immigration, Exclusion & Urban Communities

People sought work, family reunion, safety, land, education, and freedom of worship, often for several reasons together. Entry procedures and citizenship laws treated groups unequally. Immigrants built institutions and participated in work and politics while also encountering exploitation and discrimination.

Labor, Collective Bargaining & Workplace Safety

A union represents workers collectively, and collective bargaining concerns negotiated employment terms. A strike withholds labor, while a lockout withholds access to work. Explain their mechanisms, legal setting, and consequences before evaluating a particular conflict.

Cities, Public Health & Everyday Life

Urban history connects institutions to ordinary life. A family’s access to clean water or a school depended on infrastructure, location, costs, and rules. People addressed problems through mutual aid, businesses, settlement houses, public agencies, and political organizing.

Problem 1

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.

Problem 2

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 3

Teaching scenario, not testimony: one family travels through New York in 1905 with relatives offering housing; another faces Chinese exclusion documentation rules on the Pacific coast in 1915. Both seek employment. Explain two reasons their experiences might differ and one similarity without making a claim about the character of either group.
Answer and explanation

Different legal categories and entry systems could create different procedures. Relatives could reduce housing uncertainty for one family. Both seek work, but we need additional records to describe their actual processing times or other motives.

Identify different dates, routes, and applicable laws. Explain how documentation and family networks affect practical choices. Recognize a shared employment aim without assuming identical motives or treatment.

Problem 4

Why can a move have both a push and a pull factor?
Answer and explanation

A family might face persecution at home while relatives offer work contacts elsewhere. Pressures, opportunities, networks, and practical constraints interact.

Problem 5

Teaching scenario: a factory cuts weekly pay by 10% while keeping hours unchanged. Workers ask for negotiations; managers cite falling sales. Families have little savings, and a court restricts a proposed strike tactic. Explain the workers’ concern, the managers’ stated constraint, and how the court decision could alter bargaining. Identify evidence for testing each claim.
Answer and explanation

Workers face reduced income for the same scheduled time. Managers claim a financial constraint that requires evidence. Restricting a tactic can reduce workers’ leverage, but the effect depends on what options remain. The scenario does not establish that every action by either side was justified.

Separate a documented pay change from asserted business need. Explain wages, household reserves, and alternatives as sources of leverage. Seek payroll, sales, orders, and the actual court ruling.

Problem 6

Why might a worker oppose conditions but hesitate to strike?
Answer and explanation

A strike risks lost earnings or dismissal, and families may lack savings. Constraints can explain choices without showing that the worker approved the conditions.

Problem 7

Illustrative classroom data: neighborhood A records 40 cases among 2,000 people; B records 30 among 1,000 in the same year. A has a recently inspected water system; other conditions are unspecified. Calculate each rate per 1,000 residents and explain whether the comparison proves the water system caused the difference.
Answer and explanation

A has the lower recorded rate, but the two-neighborhood comparison does not isolate water quality. Inspection evidence supports a plausible mechanism; additional comparisons and context are needed to estimate its contribution.

A: 20 per 1,000; B: 30 per 1,000. The smaller raw total in B conceals its higher rate. Compare reporting, household conditions, and timing before making a causal claim.

Problem 8

Why is “crowded cities cause disease” too simple?
Answer and explanation

It omits sanitation, water quality, building conditions, and health knowledge. Similar densities can have different outcomes when services differ.
