Summarize the point that Jacob Riis is making, in your own words.

To complete question, the passage your question is referring to from Jacob Riis's “how the Other Half Lives” is written below

"With no steady hand to guide him, the boy takes naturally to idle ways. Caught in the street by the truant officer, or by the agents of the Children’s Societies, peddling, perhaps, or begging, to help out the family resources, he runs the risk of being sent to a reformatory, where contact with vicious boys older than himself soon develop the latent possibilities for evil that lie hidden in him. The city has no Truant Home in which to keep him, and all efforts of the children’s friends to enforce school attendance are paralyzed by this want. The risk of the reformatory is too great." – Jacob Riis”

Explanation:

when studying cause and effect, historians usually group the causes into different categories. for example, cultural causes reflect how a society’s literature and art convey the way the society saw itself in relation to the rest of the world. another resource that historians use to understand society is pop culture, which tells them the trends and ideas that are preferred by the common people. when studying cause and effect, it’s important to remember multiple causation, or the idea that an effect could have several causes and vice versa.  

the correct option is “cultural causes” since art and literature are related to the culture of a place. culture is determined by literature, art, music.

the correct option is “pop culture” since it reflects the likes and ideas of common people whereas the rest of the options do not focus on common people.  

the correct option is “multiple causation” since it refers to the idea that events are caused by multiple reasons, not just a single one.
