In Minnesota, children ages 12-17 may swim only when a lifeguard is on duty.

• A. Not sure
• B. True
• C. Sometimes
• D. False

Answer: (B)

The idea being tested is that supervision by a lifeguard is required during open-swim for certain pools to keep minors safe. In Minnesota, pools typically require a lifeguard on duty for open swim, and this rule applies to younger swimmers in the 12–17 age range, meaning they may swim only when a lifeguard is present. This policy exists because lifeguards provide trained surveillance, enforce rules, and are ready to respond to emergencies, which helps reduce drowning risk for swimmers who might be less experienced or less aware of hazards. If a pool isn’t staffed with a lifeguard, the facility will often restrict swimming for minors or require closer adult supervision, depending on local rules. The other options would imply uncertainty or a different policy, but the clear safety practice reflected here is that lifeguard presence governs when those age groups may swim.
