Final Answer
No, Maddie's grandfather doesn't believe that Polly died from the fever.
Step-by-step explanation
Maddie's grandfather holds a distinct belief about Polly's passing. He likely bases this on observations, historical context, or personal experiences. It's conceivable that he might have lived through periods where illnesses were more prevalent, giving him a different perspective on how diseases manifest and their outcomes.
Moreover, his skepticism could arise from inconsistencies in the narrative surrounding Polly's death. Perhaps he noticed symptoms or circumstances that didn't align with a typical fever-related demise. His doubt might stem from a deeper understanding of medical conditions prevalent during that time, allowing him to perceive nuances missed by others. Additionally, cultural or familial beliefs could influence his viewpoint, leading him to question the commonly accepted cause of Polly's death.
His perspective might involve a mix of skepticism towards the fever's assumed role and an alternative explanation supported by his own reasoning or information available to him. This stance could be a result of his critical thinking, experience, or a combination of both, challenging the conventional notion and leading him to conclude differently about Polly's passing.
