What happens with the apple on chapter 4 the giver?

In Chapter 4 of "The Giver," Jonas experiences his first "stirrings" while playing catch with an Apple. This awakening of physical desires marks the beginning of his emotional and hormonal development, which the society tries to suppress through injections. It is a significant moment that foreshadows Jonas's growing awareness of the limitations and control placed on him and the community by the Elders.
