The correct answer is A) a group of poorly maintained and overcrowded apartments.
A tenement was a group of poorly maintained and overcrowded apartments.
During the Industrial Revolution, many immigrants came to the United States escaping from political and religious persecution in their native countries, or they were looking for better living conditions for their families. Also, people that lived in rural America decided to move to larger cities where manufacturing plants needed extra hands. These people used to live in tenements, which were apartment buildings where immigrants and workers lived in overcrowded spaces under unhealthy and dirty conditions.
