Question

Quizplus · Accepted Answer

Witnessing a robbery at gunpoint would likely activate the sympathetic nervous system, which would make the body prepare for fight or flight. This may lead to an increase in heart rate and blood pressure to help supply oxygen and nutrients to the muscles, making option A the best choice. Options B and C may be associated with the parasympathetic nervous system, which has the opposite effect and would not be activated in this situation. Option D, a decreased heartbeat, would not be beneficial in a potentially dangerous situation, so it is not the best choice.
