My guess is that your book gives certain answers you are supposed to remember because this is a topic that could have a variety of answers.
I would say that industrialization in today's world is happening mainly in the developing world. The rich countries have already industrialized long ago and are moving away from industry towards doing things like engineering and software development.
In the developing world, industrialization has many impacts. One is that it attracts people to the cities where they often live in slum conditions. They are lured by the prospect of jobs and money -- more than they could get as farmers. A second impact is that this movement strains social systems. Cultures used to be based on extended family networks in rural areas. Now these networks and support systems are being broken as people move to the cities.
Industrialization had both a positive and a negative impact.
the Industrial Revolution dramatically changed every aspect of human life and lifestyles. People enjoyed a more comfortable and luxurious lifestyle. Travel became faster, safer and more comfortable. Human health and life longevity improved tremendously. Modern banking and commercial practices and the stock market are a direct result of industrialization. It impacted education especially engineering education. In short, food production, travel, leisure [because of the invention of labor saving devices], medicine, housing and clothing were all influenced positively by industrialization.
The negative aspects of industrialization, are global warming, climate change, pollution, exploitation of the poor, child labor and greed and materialism.
