Final answer:

Step-by-step explanation:
Adolescence in contemporary industrialized societies begins earlier in life and ends later in life as compared to previous centuries.
In pre-industrial society, children were considered adults when they reached physical maturity. However, in contemporary industrialized societies, there is an extended time between childhood and adulthood called adolescence.
Today, adolescence is seen as a time to develop independence from parents while remaining connected to them. The typical age range of adolescence is from 12 to 18 years, but it can extend well into the early 20s.
