Final answer:
The provided texts do not include a character named Belisa or details on how she prepared to last through winter. Instead, they feature various other characters dealing with cold or adverse conditions, highlighting actions taken to provide warmth and shelter.
Step-by-step explanation:
The given excerpts do not directly answer the question of how Belisa, who is not mentioned in any of the excerpts, prepared to last through winter. The character Belisa is not referenced in the provided texts, and as such, there is no accurate way to tell how she prepared for the winter. However, several characters in the different excerpts are depicted as dealing with cold or preparing for harsh weather or other conditions, suggesting themes of endurance and preparation.
For instance, the character in one excerpt steals a bag to protect against the cold while sleeping, which shows a method of preparation for the winter aimed to avoid hypothermia. In another, Calixta is seen sewing, which could imply she is preparing garments for the upcoming colder season. Lastly, there is mention of cutting spruce boughs for bedding, an action related to creating shelter and warmth during cold times.
