Question

a higher than normal fever is a(n) ______
feedback
nodding
law
illness response

Explanation:

A higher - than - normal fever is a body's response to an illness. The body's immune system may trigger a fever as part of its defense mechanism against pathogens or other abnormal conditions. "Feedback" is about information return, "nodding" is a physical gesture, and "law" is a rule or regulation, none of which relate to a fever's nature. So the correct option is related to the body's reaction to illness.

Answer:

illness response (the option in the red box at the bottom right)
