Final answer:
The United States became a diverse society through immigration and industrialization, with immigrants filling labor demands in urban areas and contributing to the nation's cultural and economic diversity.
Step-by-step explanation:
Two ways the United States became a diverse society were through immigration and industrialization. These processes were deeply interconnected during a time of significant growth and change in American society. Immigration brought people from various backgrounds and cultures to the United States, seeking opportunities and a better life. Many immigrants found work in cities where industrialization created a need for labor. Consequently, the cities grew larger and more diverse as they absorbed these populations.
As urbanization proceeded rapidly during the Industrial Era, more jobs in factories appeared, drawing in both domestic rural populations and international migrants. While industrialization and economic growth brought advancements in technology, communication, and transportation, living conditions for many urban laborers were harsh, with poverty and grueling working conditions being common. Despite these difficulties, the chance of better wages in industrial labor attracted large numbers of immigrants, contributing further to the diversification of the urban population.
Therefore, the correct answer to the question is: Two ways the United States became a diverse society were c) Immigration and industrialization.
