Answer:
The best descriptions for the living and working conditions of the urban poor at the turn of the twentieth century, are: unsafe, unsanitary and unsanitary.
Step-by-step explanation:
At the turn of twentieth century, and because of industrialization, and a decrease of opportunities in rural areas, the urban regions became overpopulated with people looking for jobs, easier access to the perks of city life, and running away from lack of opportunities in the country. As such, cities like Chicago, New York, among others not just in the United States, but around the world, began to face a problem of overcrowding especially in living areas, and the working places fared no better. In factories, there was little regulation on how workers did their jobs and apart from crowding, they had to face unsanitary conditions, which caused a lot of incidents and accidents. This without mentioning that buildings were not appropriately adapted to sustain so many workers safely, and ensure their safety. In living conditions things were not much better, and there was a burst of production of really small and clustered living units where families with more than 5 members could live in really small spaces. All these conditions made the urban poor face really unhealthy, unsafe and unsanitary situations.
