To understand why immigrants moved to America in the late 1800s, it is important to consider the historical context of that time. The late 1800s marked a period known as the "Age of Mass Migration," during which millions of people migrated from various parts of the world to the United States. There were several reasons behind this significant movement:

B. Help build the railroads: One of the major reasons immigrants moved to America in the late 1800s was to work on building railroads. The expansion of railroads was a massive undertaking during this period, and immigrant labor played a crucial role in constructing and extending the railway network across the country.

C. From megalopolises: This option does not accurately describe the main reason for immigration in the late 1800s. Megalopolises refer to large cities or urban regions formed by the merging of multiple cities. While some immigrants may have come from urban areas, it was not the primary reason for their migration.

D. Live in the Sunbelt states: The concept of the "Sunbelt" as a popular destination for immigrants emerged later, primarily during the mid-20th century. It refers to the southern and southwestern regions of the United States, where there is abundant sunshine and a warmer climate. This option is not relevant to the late 1800s context.

Therefore, the correct answer is:

B. Help build the railroads. Immigrants were drawn to America in the late 1800s to participate in the construction of the expanding railroad network.
