I think these events happened at the beach because the beach represents the full circle the boys come from the beginning of the book to the end. In Chapter 1, the beach shows their innocence as children, wanting to play in the water. By the end of the book, the children have gone through their savagery, and they are then rescued on the beach, where Ralph is being chased by Jack and the other boys.
In Lord of the Flies, the importance of the conch is to symbolise democracy and fairness. In the first few chapters of the novel, the conch plays an evident part and is the reason leadership and rules are created, and are a reason the boys are able to be at peace with each other to start with. Yet, as their time on the island progresses, the conch becomes less valuable to the other islanders, except Piggy who carries the conch with pride, and Ralph, who feels it still has the ability and power it had initially, and keeps order. In the chapter "Castle Rock", Piggy holds the conch tight by his side, and tries to form another assembly. He clearly feels that despite the segregation of the children, the conch is still a symbol of authority. So, when Roger kills Piggy with the rock and shatters the conch, it shows the real breaking down of the group. The conch shatters, as does the rules and the capable knowledge of Piggy.
Well the importance of Simons death is to show how democaracy s truley crumbling because Simon was the "christ- figure" so when the boys murdered him, that showed the lack of innocence and the boys are becomming more like savages.
But the question with the conch, I really don't know, sorry.
I disagree, the importance of Simons death is all to do with nature. Throughout the book, Simon when feeling weak refuges to the dome created by candle-buds and thickett. As a result of the 'tribes' brutal ritual, Simon lays dead, washed up on the beach. This could signify that nature once again helped Simon escape the island, and the only way he escaped the island was death.
thanks a lot!!!
