Question

poor sanitation and polluted water spread diseases like typhus, cholera, and smallpox.
even though working conditions were difficult for factory workers, most of them could afford comfortable living conditions.
because of the demand for workers, there were few unemployed or homeless people.
row houses and tenements were terribly overcrowded.

Explanation:

Analyze historical conditions of industrial cities

Industrialization led to rapid, unplanned urbanization, resulting in severely overcrowded housing (tenements and row houses) and a lack of public infrastructure.

Evaluate sanitation and public health

The absence of proper sewage systems and clean water supplies caused widespread epidemics of waterborne and infectious diseases such as cholera and typhus.

Assess economic realities of working class

Most factory workers earned very low wages, faced high unemployment risks, and could not afford comfortable living conditions, making the other statements historically inaccurate.
