Final answer:
In 'Lord of the Flies,' the boys use Piggy's glasses to start a fire, which symbolizes both hope for rescue and the link to civilization.
Step-by-step explanation:
In Lord of the Flies, the boys start a fire by gathering dry wood and using Piggy's glasses to focus the sunlight and ignite the wood. They create a foundation for the fire to prevent it from being extinguished and carefully build it up with small twigs before adding larger branches. The fire symbolizes not only their hope for rescue, as its smoke is meant to signal passing ships, but also the boys' connection to civilization and their descent into savagery as they struggle to maintain it.
