In chapter 3 of Lord of the Flies, why does Ralph insist on building the huts, and what do they represent?

Ralph desires shelters for protection from the sun and the
rain. The shelters are a form of civilization. Ralph desperately tries to create some
form of civilization and order. Only Simon seems to be helping Ralph. Jack and the
hunters are preoccupied with hunting meat. Ralph is becoming discouraged, but he and
Simon continue to put together shaky shelters.

Ralph needs
shelters to protect them from the harshness of nature. Also, he desires to help the
littluns feel more protected, especially since they are so afraid of the beast. Ralph
reminds Jack that the littluns scream in the middle of the night. The shelters will
offer the littluns a sense of protection from their fear of the
beast.

Ralph and Jack are divided in their ideas for

By the end of this chapter, Jack and Ralph seem
to be moving in different directions. Ralph struggles to retain what is civilized, as

Ralph will continue to
build shelters and a fire to attract a ship for possble rescue. He will maintain some
type of order while stranded on the island. He sees the need to create a civilized
atmosphere.
