Final answer:
There is no information pertaining to Marji's last memory of her parents in the provided text excerpts, making it impossible to provide an accurate response to the student's question based on the given references.
Step-by-step explanation:
The student's question about Marji's last memory of her parents before leaving is actually not directly answered by any of the given text excerpts.
None of the excerpts describe a character named Marji or her specific last memory with her parents. This seems to either be asking about a different piece of literature or may refer to Marjane Satrapi's graphic novel "Persepolis," which is not mentioned in the provided text.
Therefore, based on the provided excerpts, it is impossible to determine Marji's last memory of her parents before leaving.
Each excerpt introduces different characters and scenarios that do not align with the specifics of the question.
To accurately answer the student's query, one would need the appropriate text or context from the work in question, which seems to revolve around a character named Marji and her experiences.
