What are the three groups of children in Lord of the Flies, what problem can you anticipate, and what is Ralph's assessment of the...

In terms of age, there are two specific groups of boys in
Lord of the Flies: the bigguns (the older boys) and the littluns
(the younger boys). Among the older boys, there is the choir, led by Jack; all of the
others not part of the choir initially become allied with Ralph. Jack's choirboys become
the hunters of the group, and they quickly become absorbed with killing the wild pigs
that roam the island. It is obvious from the start that Jack has a hunger for power, and
he is unhappy that he is not voted the leader instead of Ralph. This power struggle
between the two oldest boys appears to be a problem from the first, and it can be
anticipated to be a continuing form of conflict. Ralph recognizes that the boys are
without the leadership of grownups, and that in order to be rescued, some form of smoky
signal fire must be kept going for rescuers to see. Ralph claims that his father, a
naval officer, has told him that there are no uncharted islands in these waters, and
that eventually the boys will be rescued.
