Two people experience the same external temperature. Person P maintains an optimum internal temperature; person Q does not. Which observation most directly suggests that Q has an effector fault?
Q detects the temperature change and processes the information but produces no corrective response.
Q does not detect the temperature change and sends no information for processing.
Q detects no stimulus because the external temperature stays the same for both people.
Q processes the information and restores the internal temperature more rapidly than P.
