Final answer:
True, The amount of conflict is greater among friends than non-friends, and conflict resolution through compromise involving mutual involvement is more common among friends than non-friends.
Step-by-step explanation:
The statement that the amount of conflict is greater among friends than non-friends, and that conflict resolution through compromise involving mutual involvement is more common among friends than non-friends, is True. Conflict among friends can arise due to the close and personal nature of the relationship, as well as shared experiences and expectations. Friends may have higher expectations of each other, which can lead to conflicts when those expectations are not met. However, because of the emotional investment in the relationship, friends are also more likely to work towards a resolution through compromise and mutual involvement.
