Final answer:
Harriet Tubman, faced with refusal for help, responded with notable restraint and unwavering commitment to her mission of guiding slaves to freedom through the Underground Railroad.
Step-by-step explanation:
When Harriet Tubman was refused shelter, she exhibited resolve and perseverance in the face of adversity, which resonates with her broader legacy as a 'conductor' of the Underground Railroad. Despite being denied victuals at a farmhouse, Tubman's response was suggestive of her commitment to the cause of freedom and her role as a prominent abolitionist. Instead of openly confronting the refusal, her reaction as described in historical accounts was understated, 'Won't you? Then I can't help it,' displaying the stoicism and determination that characterized her numerous daring missions to lead enslaved individuals, including her own family, to freedom. She distinguished herself through her efforts and became known as an American Moses, noted for her bravery and successful rescue operations that liberated many from the bonds of slavery.
