How will Richard’s body react when a friend jumps in front of him and scares him?

A sudden scare activates the sympathetic nervous system, which prepares the body for a fight-or-flight response, such as a faster heartbeat and increased alertness. The parasympathetic nervous system, which supports rest and recovery, plays a lesser role during this response. So the correct choice is “Richard’s sympathetic nervous system will take over, and his parasympathetic nervous system will play a lesser role.”
