Which of the following is a true statement about the industrial revolution?

a it took place only in northern cities.
b it introduced new ways of manufacturing.
c it introduced new methods of farming.
d it made fewer workers necessary in factories.

The right answer is the B) It introduced new ways of manufacturing.

Explanation: Just to elaborate a little on the answer, it can be added that the Industrial Revolution did not only take place in Northern cities or states, it demanded a very significant amount of workers and it is described as industrial because it revolutionized the industry, not farming and agriculture, so the other options must be discarded. By creating inventions such as the spinning jenny and the steam engine, among many others, manufacturing a wide variety of goods, from cotton to paper or flour, just to name a few, changed radically, allowing for a much faster, extensive and cheaper production.
