Question

when jack was learning driving, he was taught about basic traffic rules and regulations. on the day of his driving test, he saw a traffic signal that turned from green to red. as soon as it turned red, jack immediately applied the brakes. which statement best explains jack’s behavior?
a. on seeing the signal light turn red, jack’s visual receptors sent a message to his brain, which processed the message according to a stored memory and caused his leg muscles to apply the brakes and stop the car.
b. on seeing the signal light turn red, jack’s brain sent a message to the visual receptors in his eyes, and his eyes transmitted this information to jack’s legs to apply the brakes and stop the car.
c. on seeing the signal light turn red, jack’s visual receptors sent a message directly to his leg muscles to apply the brakes and stop the car.

Explanation:

Jack's behavior involves sensory input (visual receptors detecting red light), brain processing using stored memory of traffic rules, and motor output (leg muscles applying brakes). Option A correctly describes this sequence: visual receptors send signals to the brain, which uses memory to trigger muscle action. Options B reverse the sensory-brain direction, and C skips brain processing (direct receptor-to-muscle is incorrect).

Answer:

A. On seeing the signal light turn red, Jack's visual receptors sent a message to his brain, which processed the message according to a stored memory and caused his leg muscles to apply the brakes and stop the car.
