Final answer:
Jonas and Gabe sleep during the day due to the rules and schedules in their dystopian society in 'The Giver.'
Step-by-step explanation:
Jonas and Gabe sleep during the day because they live in a dystopian society where everyone is required to adhere to strict rules and schedules. In Lois Lowry's novel, 'The Giver,' Jonas and Gabe are being trained to become Receiver and are given a daily injection that suppresses their emotions and enables them to have a more controlled and predictable life. One of the rules in their society is that they must conform to a strict sleep schedule, which includes sleeping during the day to ensure they are well-rested and ready for their assigned tasks.
