Final answer:
In 'The Giver', Jonas starts taking pills to suppress his adolescence stirrings, which are intended to control emotions for societal stability, and he is expected to take them into adulthood.
Step-by-step explanation:
In The Giver, Jonas has to start taking pills to suppress his 'stirrings', which are the feelings of attraction and desire that start to emerge during adolescence in the dystopian society portrayed in the book. These pills are meant to suppress emotions and maintain the societal goal of Sameness. Jonas is expected to take the pills from the onset of these stirrings throughout his adult life, as is customary for all members of the community, in order to prevent the emotional and societal chaos that the founders of the society believe would ensue without such control.
