!!!?? I need help with 2 Industrial Revolution questions.
Igoryamba

The Industrial Revolution changed the economy as it created more jobs, increased trade, and raised prices and lowered salary's. The Industrial Revolution opened a window for large business companies and factories for many, but factory life was very harmful and paid little to none. Thus requiring families to have children work just to have enough income for basic necessities. Trade was on the rise as goods were manufactured swiftly and efficiently.

The Industrial Revolution changed society as it caused urbanization, decreased safety, caused huge overcrowding and pollution. During the Industrial Revolution, safety within factories was not a priority and many workers were harmed or killed in work. Overcrowding occurred as many had to move from rural to urban areas to get jobs, thus crowding in slums and tenants. Pollution, specifically air and water pollution, was on the rise as smoke from factories increased green house gases and factories dumping out sewage in open bodies of water polluted the water.

zmey [24]

The Tyler and Polk administrations

Both administrations strongly supported American westward expansion.

John Tyler pressed for the annexation of Texas as a slave state during his administration (1841-45) and at the end of it, he signed a Texas annexation bill into law, which was admitted as a state in the first year of Polk's presidency.

James K. Polk, who ruled from 1845 to 1849, also supported American  expansion to the point he led the U.S. into the Mexican-American War (1846-48) in which the U.S. gained what is today California and much of the present-day Southwest.
