Answer:
a. People moved from the countryside to the city.
Step-by-step explanation:
The industrial revolution marked the change of life and manufacturing of goods, which impacted the lives of people, especially in Europe and the US. Technological advances allowed the process of making goods to be done mechanistically and by machines. There was a rise in factory development and system.
This put life in the countryside and a self-sufficient lifestyle in the second plan. Work and home did not have to be tied together anymore. Instead, people left family and home to go to work during the specific hours. They did not manufacture the goods needed for life themselves but would work and earn money to buy those goods which have been produced. The construction of the railway also provided easier travel and connection to the larger cities.
This all resulted in the fact more people moved to cities from the countryside. They wished for a better life, more money, education, and different living settings.
