Question

which of the following best explains why immigrants and factory owners worked together but often lived in different parts of a city?
immigrants usually lived on the outskirts of cities far from the places where they worked.
legal restrictions forced immigrants and factory owners to live in separate parts of cities.
factory owners preferred to live on the outskirts of cities in neighborhoods that reminded them of rural areas.
public transportation made it possible for factory owners to live in parts of a city that immigrants could not afford.

Explanation:

Factory owners, with more financial means, could afford to live in better - off areas accessible via public transportation. Immigrants, often with lower incomes, could not afford such areas. There were no legal restrictions forcing this separation, and immigrants usually lived close to work for convenience. Factory owners' preference for rural - like outskirts is not the main reason for the separation.

Answer:

D. Public transportation made it possible for factory owners to live in parts of a city that immigrants could not afford.
