Which of the following is not a skill for settling inter-communal conflict?

The skill for settling inter-communal conflict that is not appropriate is war. War is a violent and destructive method that can cause significant harm, loss of life, and property damage. In contrast, dialogue, mediation, and arbitration are non-violent conflict resolution methods that aim to find peaceful and mutually beneficial solutions to disagreements between communities. Dialogue involves direct communication between parties to clarify misunderstandings, identify common ground, and find solutions to the conflict. Mediation involves a neutral third party who facilitates communication and helps parties to find common ground and resolve the conflict. Arbitration is similar to mediation, but the third party has the authority to make a binding decision that the parties agree to accept. Therefore, war is not a skill for settling inter-communal conflict as it is a violent and destructive method that should be avoided whenever possible.
