An original campaign model gives planners two reachable islands. Cairn has a repair anchorage needed for the next operation; Stone has no useful facilities and a much stronger garrison. What is the best reason to prioritize Cairn?

It places every enemy island under immediate occupation.Its facilities can sustain the next operation without requiring an assault on every stronghold.Its location makes all future resupply unnecessary.Its weaker defenses prove that the entire campaign will be bloodless.

A force sails past a fortified island, but that island’s aircraft continue attacking the force’s supply ships. What important condition of a workable bypass has not been met?

The force has not captured every island in the ocean.The bypassed island has not become a civilian port.The threat to the advancing force’s supply route has not been sufficiently contained.The advancing force has failed to avoid all use of aircraft.
