Explanation:

All of these were elements that were present in society during the Industrial Revolution. During these years, industry developed in many cities. The availability of jobs led people to move from rural to urban places. This led to the overcrowding of cities, as well as poor sanitation. However, when people arrived to the cities, they often struggled to find work. Even when they did, they worked long hours and received very low wages.
