When children are near a pool, pond, or stream, the supervising adult
A. should wear a whistle.
B. should wear a life jacket.
C. must be within an arm's length.
D. needs to check on the children every five minutes.

The answer is C, must be within an arm’s length. Usually a lifeguard will wear a whistle in order to give a warning to a swimmer or to issue some other instruction. The supervising adult does not need to be wearing a life jacket as they are merely supervising. Checking a child every five minutes is not adequate because a drowning can occur much faster than that. The question does not specify how old the child is, but the answer C is the correct answer.
