Final answer:
The character's motivation inferred from the final paragraph is to honor and remember the deceased woman, based on the considerate preservation of her remains.
Step-by-step explanation:
Based on the narrator's actions in the final paragraph, we can infer that the character's motivations are to honor and remember the deceased woman, as evidenced by the care and intention behind preserving her corpse. This option is supported by the contextual information provided, which indicates a deep consideration for the deceased's dignity amidst concerns about the malady, inquiries from medical professionals, and the state of the burial grounds.
The actions described do not directly suggest an intent to clean up the cemetery, raise awareness for historical conservation, or build a relationship with a sibling. Instead, they represent a reverence for the deceased and a desire to protect her remains in a respectful manner.
