Final answer:
Adolescence is a socially constructed concept that varies between cultures. In Western cultures, the beginning and ending of adolescence is clearly marked, whereas in Eastern cultures, it may not be as clearly defined.
Step-by-step explanation:
Adolescence is the period of transition between the beginning of puberty and adulthood. It is a socially constructed concept and varies between cultures. In Western cultures, the beginning and ending of adolescence is clearly marked, whereas in Eastern cultures, it may not be as clearly defined.
For example, in some Western cultures, turning 18 or graduating from high school is seen as the end of adolescence and the beginning of adulthood. However, in Eastern cultures, there may be more emphasis on other milestones such as marriage or starting a career.
It is important to note that the concept of adolescence itself is not biologically determined, but rather a product of cultural and societal norms and expectations.
