In the late 1800s sweatshops and other factories were horrible places to work what evidence supports this point of view

The correct answer to this open question is the following.

Sweatshops is a pejorative term used to identify a workplace with poor working conditions. In the 1800s and due to the Industrial Revolution, many people left the rural areas of the country to emigrate to the larger cities where factories offering jobs were located. These jobs paid low wages and the workplace was unhealthy with minimum or no safety at all. Some places really offered unhuman conditions, workers had to wor for long hours, there was not enough ventilation, and some factories even hired children.
