Final answer:
Peter the Hermit's favourite hobbies likely included social and cultural activities common during his time such as making music, dancing, and telling stories, as well as engaging in creative behaviour like tool and ornament making.
Step-by-step explanation:
Peter the Hermit's favourite hobbies are not specifically enumerated in historical accounts, but based on the context provided, we can infer some of his interests. If we consider the broader social and cultural activities of the time, such as making music, dancing, and telling stories, it's plausible that these were common among people like Peter the Hermit as well. In the reference to Peter as a figure preaching the First Crusade, it can be deduced that he was also passionate about his beliefs and the cause of the crusades, indicating a hobby or interest in religious and social advocacy. As a knight who believes in social justice (option A), Peter likely engaged in activities that aligned with his values, which could have included various forms of creative behaviour such as tool and ornament making, a common practice of the time. However, the options provided about reading books, having no friends, and loving toys do not specifically align with the known activities of Peter the Hermit, making them less likely to be his favorite hobbies.
