What is the theme of first chapter in Wizard

In the first chapter of "The Wonderful Wizard of Oz," we are introduced to the main character, Dorothy, and her life on a farm in Kansas. The central theme of this chapter is the longing for a better life and a sense of dissatisfaction with her current circumstances. Dorothy is portrayed as a kind and caring girl, but she also feels restless and longs for something more exciting and fulfilling in her life. The imagery of the cyclone that whisks Dorothy away to the magical land of Oz symbolizes this desire for change and adventure.
