In the story The Lord of the Flies, what are three major complications that take place in and throughout the book?

The major conflicts that arise in Lord of the
Flies primarily occur between the boys as they try to survive their ordeal on
the island. Perhaps the prime complication comes between Ralph and Jack in their battle
for leadership supremacy. Although Ralph is elected leader of the stranded boys, Jack
refuses to accept the democratic decision, and he eventually takes control through force
and fear. Another conflict arises in the boys' perception of Piggy. The most intelligent
and scientifically adept of the boys, Piggy's outward appearance--he is pale, overweight
and has poor vision--is all the boys seem to see. His suggestions are usually denounced;
even Jack, who knows that Piggy is his most loyal and trusting ally, takes him for
granted, and Piggy is eventually killed. Another conflict comes in the form of the
beast, which represents evil and which instills fear in the boys. Eventually, as Jack's
hunters slowly grow less fearful, they decide to kill the beast and hang his head on a
pole. This act completes the boys' total collapse into
barbarism.
