A small amount can increase alertness, but high stress leads to narrowed attention, poor decisions, and task saturation

Answer

Stress entirely eliminates human error

Answer

It always improves reaction time and decision-making

Answer

Stress has zero impact on pilots controlling drones remotely

Question 16

What atmospheric mechanism typically causes a 'sea breeze' during the daytime?
