The arrival of the ship represents hope and rescue for the boys stranded on the island. Ralph has been struggling to maintain order and civilization, and the ship signifies a return to the adult world and the possibility of escaping the savagery that has taken hold on the island.
Here's why:
* Hope for rescue: The ship is a symbol of escape from the island and the escalating chaos. Ralph is desperate for help and sees this as their chance to be saved.
* Validation of his leadership: The ship's arrival validates Ralph's efforts to maintain order and keep the fire going as a signal for rescue. He has been working tirelessly towards this goal, and it finally seems to be paying off.
* Relief from responsibility: Ralph has been burdened with the responsibility of leading the boys, a task he finds increasingly difficult. The ship offers him a chance to relinquish this responsibility and return to a normal life.
Therefore, Ralph is filled with relief, hope, and joy when he sees the ship, not anger.
