A. The living conditions in urban slums and child labor.

Explanation:

Jacob Riis was a police journalist in New York. In 1888, Riis took pictures of what life resembled in city's ghettos. Utilizing his very own photographs just as photographs accumulated from different photographic artists, Riis started to give addresses titled, "The Other Half: How It Lives and Dies in New York," in which he would demonstrate the photos on a projection screen and portray for watchers what the circumstances resembled. He gave his addresses in New York City places of worship. In 1989, a magazine article by Riis (in light of his addresses) was distributed in Scribner's Magazine. The book variant was then distributed in 1890 as How the Other Half Lives: Studies among the Tenements of New York.  

Riis accused the poor living conditions for voracity and disregard from society's wealthier classes, and approached society to cure the circumstance as an ethical obligation.
