How does the author use foreshadowing in Jackaroo?

In Part I, the author foreshadows Gwyn's role as the Jackaroo Part I her role as Jackaroo when she is standing in the Doling Room, observing the women in ragged clothes and tattered shoes filled with straw. Gwyn feels guilty for having a warm cloak and sturdy boots, and out of sympathy for one of the older women, she offers to carry the woman's food basket. As they walk together, the woman tells her tales of Jackaroo, a legendary hero of the poor whom she claims to have seen once long, long ago. She then asks Gwyn a significant question: "There's no one then, bold enough, brave enough to stand for the poor when the Lords get greedy, or when times are bad?"
