How does the world of the island mirror the real world once the boys are rescued by the naval officer lord of flies?

The naval officer represents the presence of authority and civilization in the real world. The chaos, violence, and loss of innocence on the island mirror the darker aspects of human nature that exist in society but are often suppressed or masked by societal norms. The contrast between the boys' behavior on the island and in the presence of the naval officer highlights the thin line between civilization and savagery.
