Task: Question Generation
Input (English): Passage: The stele was erected after the coronation of King Ptolemy V and was inscribed with a decree that established the divine cult of the new ruler. The decree was issued by a congress of priests who gathered at Memphis. The date is given as "4 Xandicus" in the Macedonian calendar and "18 Meshir" in the Egyptian calendar, which corresponds to March 27, 196 BC. The year is stated as the ninth year of Ptolemy V's reign (equated with 197/196 BC), which is confirmed by four named priests  who officiated in that same year: Aëtus son of Aëtus was priest of the divine cults of Alexander the Great and the five Ptolemies down to Ptolemy V himself; his three colleagues, named in turn in the inscription, led the worship of Berenice Euergetis (wife of Ptolemy III), Arsinoe Philadelphos (wife and sister of Ptolemy II), and Arsinoe Philopator, mother of Ptolemy V. However, a second date is also given in the Greek and hieroglyphic texts, corresponding to 27 November 197 BC, the official anniversary of Ptolemy's coronation. The inscription in demotic conflicts with this, listing consecutive days in March for the decree and the anniversary. It is uncertain why such discrepancies exist, but it is clear that the decree was issued in 196 BC and that it was designed to re-establish the rule of the Ptolemaic kings over Egypt.The decree was issued during a turbulent period in Egyptian history. Ptolemy V Epiphanes reigned from 204 to 181 BC, the son of Ptolemy IV Philopator and his wife and sister Arsinoe. He had become ruler at the age of five after the sudden death of both of his parents, who were murdered in a conspiracy that involved Ptolemy IV's mistress Agathoclea, according to contemporary sources. The conspirators effectively ruled Egypt as Ptolemy V's guardians until a revolt broke out two years later under general Tlepolemus, when Agathoclea and her family were lynched by a mob in Alexandria. Tlepolemus, in turn, was replaced as guardian in 201 BC by Aristomenes of Alyzia, who was chief minister at the time of the Memphis decree.Political forces beyond the borders of Egypt exacerbated the internal problems of the Ptolemaic kingdom. Antiochus III the Great and Philip V of Macedon had made a pact to divide Egypt's overseas possessions. Philip had seized several islands and cities in Caria and Thrace, while the Battle of Panium (198 BC) had resulted in the transfer of Coele-Syria, including Judaea, from the Ptolemies to the Seleucids. Meanwhile, in the south of Egypt, there was a long-standing revolt that had begun during the reign of Ptolemy IV, led by Horwennefer and by his successor Ankhwennefer. Both the war and the internal revolt were still ongoing when the young Ptolemy V was officially crowned at Memphis at the age of 12 (seven years after the start of his reign), and the Memphis decree issued.
Output (English): What was the full name of the person who became ruler at the age of five after the sudden death of both of his parents?
