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.

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.

The correct answer is... They were afraid the admission of new free states would tip the balance.

Final answer:

The availability of water power, development of mechanized manufacturing processes, and access to abundant natural resources were the most vital factors contributing to the development of northern manufacturing centers in the early 1800s.

Explanation:

In the early 1800s, the most important factor in the development of northern manufacturing centers was the availability of water power, access to abundant natural resources, and the invention of mechanized manufacturing processes. The Industrial Revolution, which started in Great Britain and eventually moved to the United States, led to rapid industrial development around the Great Lakes, an area referred to as the 'Manufacturing Belt'. Mechanized manufacturing initially embraced textiles in New England and moved subsequently to steel and other metals in Pennsylvania and Indiana.

Following the War of 1812, industrialized manufacturing expanded enormously in the North. Wealthy merchants in New England constructed water-powered textile mills along the many rivers of the region. These mills brought new production methods where work was mechanized, centralized, and specialised. As a result, the nature of work changed drastically, moving from highly skilled artisans to wage laborers performing repetitive deskilled tasks. Furthermore, the development of the steam engine in this era allowed factories to operate independently of natural water sources, contributing to urban industrial growth.
