Answer:
To "bear witness" the living can prevent the tragic story of the ghost boys from being repeated with living children and this can contribute to a better world.
Step-by-step explanation:
This question is about "Ghost Boys" a book written by Jewell Parker Rhodes that tells the story of Jerome, a twelve-year-old boy who was killed when a police officer shot him when he mistook Jerome's toy for a real gun. Jerome became a ghost and saw all the suffering that his family went through with his death. Thus, he decided to form a group with other ghost boys and show some living people the tragic stories that caused their death. This is because only these humans can develop real changes in the world, helping other children not to go through the same injustices that they did and preventing more families from suffering.
