Final answer:
The metaphor comparing Harry's children to seeds in paragraph 2 implies that children have the potential to grow and thrive, given the proper care and environment, indicating Harry's commitment to nurturing their development.
Step-by-step explanation:
The comparison of Harry's children to seeds in paragraph 2 creates the idea that the children, like seeds, have the potential to grow and develop, requiring care and nurturance. This metaphor suggests a starting point for a journey of growth and an inherent capacity for transformation and change. Just as seeds need the right environment and care to grow into plants, Harry's actions in creating space for them by moving the seedlings indicate his commitment to providing such an environment for his children's development.
