Question

what was not a problem in most u.s. cities in the nineteenth century?

○ fire

○ disease

○ unemployment

○ crime

Explanation:

In 19th - century U.S. cities, fire was a major problem due to wooden structures and lack of modern firefighting. Disease was rampant due to poor sanitation. Crime was common in urban areas with rapid growth and social disorganization. However, the 19th - century U.S. was in a period of industrial growth, and unemployment was not as widespread a problem as the other three in most cities (though it existed in some contexts, it was not a defining problem like fire, disease, or crime across most cities).

Answer:

unemployment
