Step-by-step explanation:
When Frederick Douglass learns about the concept of slavery, his biggest concern is the fear of being separated from his grandmother. In his narrative, Douglass describes the deep emotional bond he had with his grandmother, and the thought of being taken away from her brought immense distress. This fear of separation reflects the cruel reality of slavery, where families were torn apart and sold to different owners.
While other concerns such as the lack of education, limited free time, and hard labor were also significant aspects of slavery, Douglass' immediate concern was the threat to his family and the potential loss of his closest connection.
