Here's why this is considered the climax:
* Turning Point: Up until this point, the story focuses on the family's struggle to adapt to the new reality of life after the meteor impact. This decision marks a shift, where Miranda chooses to break away from the safety and familiarity of her family to pursue a new path, hoping to find help and resources for her family in Pennsylvania.
* High Stakes: The journey is fraught with danger and uncertainty. Miranda faces potential food shortages, natural disasters, and even the threat of violence from desperate people. The success or failure of this journey could have dire consequences for her family.
* Resolution: The climax sets the stage for the resolution of the story. Miranda's journey, though dangerous, ultimately leads her to a place of hope and a new understanding of her own resilience and the power of human connection.
While the story continues after this climax, the decision to leave her family and embark on a journey of uncertainty is the defining moment that shapes the narrative and reveals the true depth of Miranda's character.
