Answer:
In the novel "Lord of the Flies" by William Golding, the conch shell is used as a symbol of order, civilization, and democracy. The boys on the island use it as a way to call meetings and to establish rules, and it becomes a symbol of their unity and their desire to maintain a sense of order and structure.
The conch shell is used primarily by Ralph, who is one of the main characters and is seen as a leader among the boys. Ralph uses the conch to call meetings and to encourage the boys to work together and to follow the rules. He also uses it as a way to assert his authority and to keep the peace on the island.
The destruction of the conch shell in Chapter 11 is significant because it marks the end of the boys' attempt to maintain order and to establish a civilized society. The conch is destroyed when Ralph is confronted by Jack and his followers, who have become increasingly violent and authoritarian. The destruction of the conch represents the breakdown of order and the triumph of savagery and anarchy over civilization and democracy.
