Answer:
B. They were usually poor and crowded.
Step-by-step explanation:
Immigrant neighborhoods, especially in the late 19th and early 20th centuries, were often characterized by poverty and overcrowding. Immigrants who arrived in the United States during this period often settled in urban areas and lived in densely populated neighborhoods, commonly referred to as "ethnic enclaves." These neighborhoods provided a sense of community and familiarity with others from the same country or ethnic background, but they often faced challenges related to poor living conditions, low wages, and limited opportunities. The American Dream and the promise of a better life drove many immigrants to endure these conditions in the hope of securing a brighter future for themselves and their families.
