which factor led to the growth of labor unions in the united states during the early 1900s? \na low wages paid to immigrant farm workers\nb unsafe working conditions in large factories\nc consumer anger over tariffs on imported goods\nd increased rates of unemployment in major u.s. cities
Answer
Brief Explanations:
To determine the factor leading to labor union growth in early 1900s US:
- Option A: Farm workers (agriculture) weren’t the primary focus of early labor unions, which centered on industrial workers.
- Option B: Large factories in the Industrial Revolution had dangerous conditions (e.g., long hours, unsafe machinery). Workers formed unions to demand safer work, fair wages, and better treatment—this directly drove union growth.
- Option C: Tariffs on imported goods relate to trade policy, not labor conditions or unionization.
- Option D: High unemployment would make workers less likely to organize (fear of job loss), so it’s not a growth driver.
Answer:
B. unsafe working conditions in large factories
