Analyze the characters of Ralph and Piggy in the work.

请帮忙给出正确答案和分析，谢谢！

Long before Ralph and Piggy came up with Jack s lot, they could hear the party. There was a stretch of grass in a place where the palms left a wide band of turn between the forest and the shore. Just one step down from the edge of the turn was the white, blown sand of above high water, warm, dry, trodden. Below that again was a rock that stretched away towards the lagoon. Beyond was a short stretch of sand and then the edge of the water. A fire burned on the rock and fat dripped from the roasting pig-meat into the invisible flames. All the boys of the island, except Piggy, Ralph, Simon, and the two tending the pig, were grouped on the turn. They were laughing, singing, lying, squatting, or standing on the grass, holding food in their hands. But to judge by the greasy faces, the meat-eating was almost done; and some held coco-nut shells in their hands and were drinking from them. Before the piirty had started a great log had been dragged into the center of the lawn and Jack, painted and garlanded, sat there like an idol. There were piles of meat on green leaves near him, and fruit, and coco-nut shells full of drink. Questions:
