Q

In order for the automatic lifeboat drain to operate properly __________.

🔍 Key Concepts

• Construction and purpose of an automatic drain plug in a lifeboat • How a ball-type check valve works to let water out but not in • Why maintenance and cleanliness of moving parts affects automatic operation

💭 Think About

• Think about which choice describes a condition that must be true all the time for the drain to work automatically, not something you manually do each time. • Which option focuses on the path and movement of the water and the ball inside the valve rather than on extra levers or caps? • Eliminate any answers that describe manual actions that would defeat the idea of an "automatic" drain.

✅ Before You Answer

• Ask: does this choice truly describe an automatic function, or a manual step someone has to take? • Check whether the option refers to keeping the drain mechanism unobstructed so the ball can move and seat correctly. • Verify that the option matches what you’d expect of a simple, passive check valve (no levers, no direction of turning involved).
