Final answer:
Many low-skilled and unskilled immigrant workers moved towards cities with factories that needed workers during the period when new immigrants were arriving at Angel and Ellis Islands. Immigrants found work in various industries and helped fuel the economic expansion of urban centers in America, despite facing challenges such as adapting to a new culture and discrimination.
Step-by-step explanation:
During the period when new immigrants arrived at Angel and Ellis Islands, many low-skilled and unskilled immigrant workers moved towards cities with factories that needed workers (option B). This was driven by the industrialization that occurred in the United States, which created a multitude of employment opportunities in urban areas. Immigrants from various countries came to America, fleeing hardships in their homelands or seeking the chance for a better life. Often these individuals congregated in cities where they could find work in industries like textiles, coal mining, railroads, and manufacturing. These areas provided the immigrant communities with familiar cultural environments and the ability to sustain their lifestyles while contributing to America's burgeoning industries.
Throughout this period, these immigrants faced several challenges, such as adapting to new languages and customs, and many also encountered discrimination and anti-immigration sentiments. However, despite these obstacles, they played a key role in America's economic expansion, particularly in the urban centers where they settled and worked.
