Final answer:
The provided texts do not explicitly mention Victor's father's advice regarding a survivor's duty after the death of a loved one, but they suggest that handling grief is a personal struggle.
Step-by-step explanation:
The provided excerpts from various texts do not contain explicit mention of Victor's father giving advice on a survivor's duty after the death of a loved one in Mary Shelley's Frankenstein. However, they do touch on themes of grief, loss, and mourning.
Victor's reflections on his own experiences and observations of others' responses to loss suggest that dealing with grief is a deeply personal journey, often fraught with despondency and a yearning for solace from sorrow. The sentiment across these texts implies that a survivor's duty, if any, might be in preserving the memory of the loved one and finding a way to continue living despite the pain of loss.
Victor's father's advice concerning a survivor's "duty" after the death of a loved one is not explicitly mentioned in the provided text.
