The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The changes that are most likely to occur as a result of civil war is a total recomposition of the powers that rule the government. Factions that fought during the war have to negotiate in order to establish a relative peace after so much death, destruction, and pain generated during the war. Socially, people have to overcome the trauma and losses provoked by the war. A period of mourning and reconstruction has to be followed, and then the faction that won the war has to start a period of "healing the wounds" and generate credibility for its government.
