Directions (77-81): Read the passage and answer the questions:

The relationship between sleep and cognitive performance has become a focal point of neurological research, with mounting evidence suggesting that sleep deprivation exerts a far more pervasive influence on mental functioning than previously acknowledged. Beyond the well-documented effects on alertness and reaction time, chronic sleep insufficiency has been shown to impair higher-order executive functions, including working memory, decision-making, and the capacity for abstract reasoning. These impairments do not manifest as sudden breakdowns but instead accumulate imperceptibly over time, rendering individuals progressively less capable without their awareness—a particularly treacherous dimension of prolonged sleep debt.

At the neurological level, sleep serves as a critical period of cellular restoration and synaptic consolidation. During non-REM sleep, the glymphatic system actively clears metabolic waste products from the brain, including amyloid-beta proteins associated with neurodegenerative conditions. Disruption of this process through habitual short sleep has been tentatively linked to elevated long-term risk of cognitive decline. Simultaneously, REM sleep is integral to emotional regulation and the consolidation of procedural and declarative memory—processes that cannot be compensated by mere wakefulness.

Despite the compelling scientific consensus surrounding sleep's restorative function, modern professional culture continues to valorise overwork and dismiss sleep as a concession to weakness. Addressing this cultural inertia requires not only individual behavioural change but also systemic institutional reform: workplaces must actively discourage practices that incentivise sleep deprivation, while public health campaigns should endeavour to reframe adequate sleep as a cornerstone of productivity and cognitive wellbeing rather than a sign of insufficient ambition.
