INDIAN HISTORY

Detailed explanation-1: -The late 19th-century United States is probably best known for the vast expansion of its industrial plant and output. At the heart of these huge increases was the mass production of goods by machines. This process was first introduced and perfected by British textile manufacturers.

Detailed explanation-2: -Industrial expansion and population growth radically changed the face of the nation’s cities. Noise, traffic jams, slums, air pollution, and sanitation and health problems became commonplace. Mass transit, in the form of trolleys, cable cars, and subways, was built, and skyscrapers began to dominate city skylines.

Detailed explanation-3: -Many lived a hand-to-mouth existence, working long hours in often harsh conditions. There was no electricity, running water or central heating. With no electric lighting (or gas) the rhythm of life revolved around the hours of daylight, and therefore would have varied with the seasons.
