Answer and Explanation:
Bud faced many obstacles to find his father and the biggest obstacle was getting rid of the adoptive family he had and facing the fear of going on a trip alone. That's because Bud's adoptive family was very violent and abusive, but at least he had a roof over his head when he was without that family. In this case, Bud's first and greatest challenge was to have the courage to flee and manage to escape from the adoptive family.
