This shows when the plane crashes on the island and you meet Ralph and Piggy and find out there are no adults with them.
Rising Action 1
This is when Ralph and Piggy find the conch in the ocean and used it to lead any other boys that survived to where they were on the island. This first shows the conch as a symbol of authority.
Rising Action 2
This is when you meet more of the boys, for example Jack, Simon, Samneric, Roger, etc. This is also when they vote Ralph the leader and decide the conch is the talking stick. Since Ralph is voted leader you see that Jack gets mad and you see the starting conflict between Jack and Ralph.
