Answer:
In the graphic novel "Persepolis" by Marjane Satrapi, Uncle Taher needs a passport because he is critically ill and requires medical treatment abroad. Due to the limitations of medical facilities in Iran during the time period, Uncle Taher's best chance for survival lies in seeking medical care in another country.
Uncle Taher's family, including Marji, undertake the difficult task of obtaining a passport for him. They face several challenges and bureaucratic obstacles along the way, as acquiring a passport in Iran during that time was a complex and often lengthy process.
To obtain the passport, Marji's family must navigate through a series of government offices, provide necessary documents, and go through numerous interviews and background checks. It is a stressful and time-consuming endeavor, but they persevere because Uncle Taher's life is at stake.
Eventually, after much persistence and overcoming bureaucratic hurdles, Uncle Taher's passport is granted. This allows him to travel to a European country for medical treatment. Unfortunately, despite their efforts, Uncle Taher's condition worsens during the trip, and he ultimately passes away.
The story of Uncle Taher's passport highlights the struggles faced by individuals in Iran during that period when seeking medical care abroad. It sheds light on the challenges and limitations of the healthcare system and the sacrifices families make to ensure their loved ones receive the best possible treatment.
In summary, Uncle Taher needs a passport in "Persepolis" because he is critically ill and requires medical treatment abroad. Obtaining the passport is a challenging process, but ultimately, it is granted, allowing him to travel for treatment. However, despite their efforts, Uncle Taher's health deteriorates during the trip, leading to a tragic outcome.
