Question

how does lack of sleep affect risk of injury?
a. it interferes with hearing.
b. it interferes with judgment.
c. it causes distractions.
d. it causes illness.

Explanation:

Lack of sleep impairs cognitive functions like decision-making and risk assessment, which are key to judgment. Poor judgment increases the likelihood of making mistakes that lead to injury. Option A is incorrect because sleep deprivation does not directly interfere with hearing; option C is vague (distractions are not a direct effect of sleep loss on injury risk); option D is incorrect because illness is a separate outcome, not the primary link to injury risk.

Answer:

B. It interferes with judgment.
