• Increased focus on minor distractions.
• Enhanced night vision leading to misjudgment of distances.

Correct answer: An inability to determine the aircraft's true attitude, altitude, or speed relative to the Earth's surface or other aircraft.

It can lead to complete loss of control. The correct answer is "An inability to determine the aircraft's true attitude, altitude, or speed relative to the Earth's surface or other aircraft.".
