Here's a breakdown of what the story could be considered a "solution" to:
1. Dorothy's Journey of Self-Discovery: The story primarily focuses on Dorothy's journey to find her way home. She learns about courage, friendship, and the importance of home and family along the way. She realizes that the power she seeks wasn't outside of herself, but within her all along. In this sense, the "solution" is Dorothy's personal growth and understanding of her own strength.
2. Social Commentary: The story can be interpreted as a commentary on the political and social issues of the time, particularly the issues of populism, capitalism, and social injustice. The Wizard's powerlessness, the Wicked Witch's greed, and the Scarecrow's search for a brain can be seen as metaphors for the struggles of the working class.
3. The Power of Imagination: The story emphasizes the power of imagination and the importance of believing in oneself. The magical world of Oz and its fantastical creatures exist because Dorothy and her companions choose to believe in them. In this sense, the "solution" is embracing the power of imagination to create a better world.
4. The Journey, Not the Destination: The story isn't just about Dorothy's journey back home, but the journey itself. The characters face challenges, learn from each other, and form strong bonds. The "solution" lies in the experience of the journey and the personal growth that comes from it.
Ultimately, the meaning and solution of The Wonderful Wizard of Oz are up to individual interpretation. There's no single right answer, and the story offers a variety of perspectives and insights.
