Final answer:
The question concerning Harry's three possible remedies for his sadness cannot be answered as presented due to lack of context and specific reference to which 'Harry' or literary source it relates to.
Step-by-step explanation:
The three possible remedies to Harry's sadness that could prevent his "herte" from being lost are not explicitly mentioned in the passage quoted or any related excerpts. The fragments presented showcase emotional moments from different literary sources including feelings of grief, helplessness, and a quest for belonging but do not provide three distinct remedies for Harry's condition. To address the student's question directly, we would need additional context or a specific reference to which 'Harry' the question pertains to and from which work of literature or situation.
