Which of the following is true about stress?

A) Any amount of stress is detrimental and should be avoided.
B) High levels of stress generally improve performance.
C) Stress facilitates performing complex tasks more than it does simple tasks.
D) Low levels of stress can be motivating.

Answer: D
Rationale: Without some stress, motivation to perform can decline. Conversely, too much stress taxes cognitive resources, resulting in poorer performance. In addition, higher levels of arousal facilitate solving relatively simple problems, while complex tasks are better performed under lower levels of arousal.
