Final answer:
Piggy's scolding about the fire on the mountaintop reveals a clash in ideals and priorities. Piggy represents practical, long-term survival needs while the other boys show impulsiveness.
Step-by-step explanation:
The conflict in the narrative with the making and quick burning out of the fire on the mountaintop, and Piggy's subsequent scolding of the group for not using the wood to build a shelter first, highlights a clash in ideals and priorities among the characters. Piggy's practical approach focuses on long-term survival needs, such as shelter, which signifies his foresight and understanding of their situation. In contrast, the other boys prioritize the immediate gratification of a signal fire, showcasing a more impulsive and shortsighted mindset. This difference underscores the themes of civilization versus savagery and rational thought versus impulsiveness that are central to the novel's exploration of human nature and society.
