what problem does jacob riis expose in this excerpt?
corruption in city government
poor living conditions in urban slums
wealthy lifestyles in upper - class new york
decline in immigrant populations
which of the following groups of people were not moving into northern urban centers in large numbers during the second industrial revolution?

Explanation:

Jacob Riis was a muckraker who focused on the living conditions of the poor. Tenements were overcrowded, unsanitary housing for the urban poor. The term "shame and disgrace" implies a negative situation, which aligns with poor living conditions. City - government corruption isn't indicated here. The mention is of tenements (not upper - class lifestyles), and there's no reference to a decline in immigrants (immigrants often lived in tenements).

Answer:

Poor living conditions in urban slums
