Question

when should a hunter wear a fall - arrest system?
a when the hunter is hauling a firearm into the stand
b when the hunter wants to take a nap in the stand
c whenever the hunter is off the ground
d when the hunter is about to shoot

Explanation:

A fall - arrest system is a safety device. Hunters should wear it for safety whenever they are off the ground. Hauling a firearm (A) or shooting (D) are specific activities, but the general safety rule is related to being off - ground. Taking a nap (B) is not the key factor. The main idea is that being off - ground poses a fall risk, so the fall - arrest system should be worn in that situation.

Answer:

C. whenever the hunter is off the ground
