1. The character that is in control of power in Lord of the Flies is Jack.  The characters that are in control of power in the Power of One are people of lighter skin.
2. Jack gains power over the boys in the Lord of the Flies by using terror, bribery, and the fear of the beast.  The boys are scared of this beast and are convinced that if they side with Jack, they will be able to defend themselves from the monster.  People of lighter skin, in the Power of One, take control over others through use of force to instill terror and fear, and technology such as batons and weapons to further add to their purpose, showing their dominance.
3. Jack maintains his position in power by being the leader, the most savage of boys in the group.  He leads the boys in hunts, demands dances, and punishes his prisoners to assure his authority in the group.  He also is able to provide meat and food which in turn gives him even more support to be the chief from the boys.  People of lighter skin maintain power by treating the suppressed poorly and oppressing with force to instill fear and despair; by doing this, the ones under suppression are surely to lose confidence and power, therefore the aggressors are able to uphold their power.
4. Jack's power is not lost nor destroyed in the novel. The power and control upheld by apartheid in South Africa is no longer enforced, so all people in Africa have equal rights and powers.
