Final answer:
The true statement about immigrants to the US in the late 1800s is that they provided crucial labor for industrialization, primarily settling in urban areas and facing significant hardships.
Step-by-step explanation:
The correct statement about immigrants to the US in the late 1800s is that immigrants provided labor that allowed the nation to industrialize. During this period, America experienced a dramatic increase in industrial output, and the labor of immigrants was crucial to this growth. Many immigrants settled in urban areas and took on jobs in manufacturing sectors, building the transcontinental railroad, and other industries. However, life for immigrants was not easy; they often faced discrimination and harsh working conditions. Notably, most immigrants did not arrive with substantial wealth, which disproves the option suggesting that most immigrants possessed wealth to start businesses. Also, the claim that most immigrants enjoyed equal opportunities or settled in rural areas does not align with the historical facts of the era.
