Why do adolescents go through puberty?

• A. To become fully socialized
• B. So that they will be able to reproduce
• C. So that girls can be taller than boys
• D. To have a fully developed brain

Answer: (B)

The main idea here is that puberty exists to enable reproduction. During puberty hormones trigger the maturation of the reproductive organs and the development of sexual characteristics, leading to the ability to reproduce. The brain-signal cascade starts the process, releasing hormones that drive the growth of primary and secondary sexual traits and fertility. While puberty brings growth and brain changes too, its central purpose is reproductive capability, not socialization, height differences, or an overall fully developed brain.
