Answer 1

Adolescence was first defined as a separate stage of life in the Western world in the 19th century.

Step-by-step explanation:

The concept of adolescence as a separate stage of life was first defined in the Western world in the 19th century. Before that, children were considered adults once they reached physical maturity. However, with industrialization and societal changes, there emerged a need to distinguish this period of transition between childhood and adulthood. This new stage of development, called adolescence, is characterized by physical, mental, and social changes, and typically spans from 12 to 18 years of age.
