Question

a circus performer was trying a new act that involved walking on a tightrope stretched between two poles. after a few practice sessions, he was able to do it perfectly. when he started performing the same act blindfolded, he lost his balance and fell into the safety net below the tightrope. which statement best explains why he fell?
a. his brain could not receive messages from his leg muscles, so he couldnt tell that he had lost his balance.
b. his brain could not process the information being sent to it by his leg muscles.
c. his visual receptors could not send messages to his brain so that it could process them and keep him balanced.

Explanation:

The scenario involves balance control, which relies on sensory feedback (e.g., from muscles, vestibular system) processed by the brain to adjust movements. Option B states the brain couldn’t process muscle information, directly linking to impaired balance regulation—since muscle feedback helps detect and correct balance loss. Other options incorrectly focus on reception (A/C) rather than processing, which is key here.

Answer:

B. His brain could not process the information being sent to it by his leg muscles.
