Research on the "Sleep Debt" Indicates That Adolescents

Research on the "sleep debt" indicates that adolescents

A) sleep long hours on weekends, which prevents any harmful consequences of too little sleep during the week.
B) sleep insufficient hours on both weekdays and weekends, which leads to an overall sleep debt.
C) sleep later on weekends than weekdays, but this does not solve problems associated with weekday sleep deprivation.
D) adjust their bedtime hours to go to sleep earlier during the week when they have to wake up early the next day to avoid a sleep debt.
E) oversleep on weekdays after going out late weekends, which causes a sleep debt in school performance.
