You are given a paragraph, with numbered sentences, and a question. Write the numbers of the sentences needed to answer the given question. Separate multiple sentence numbers with a comma (", "). E.g. "1, 2" would be the correct response if Sent 1 and Sent 2 are needed to answer the given question (do not include sentences that contain no information that is necessary to answer the question). Sort the sentence numbers in an increasing order (i.e., '1, 2', instead of '2, 1'). Your answer should not contain anything than the sentence numbers separated by a comma (e.g. '1, 2, 3, 4'). The given question requires more than one sentence to answer. So, your answer must contain at least one comma (", ").

Input: Consider Input: Paragraph- Sent 1: Alexander's death was so sudden that when reports of his death reached Greece, they were not immediately believed.
Sent 2: Alexander had no obvious or legitimate heir, his son Alexander IV by Roxane being born after Alexander's death.
Sent 3: According to Diodorus, Alexander's companions asked him on his deathbed to whom he bequeathed his kingdom; his laconic reply was "toi kratistoi"--"to the strongest".
Sent 4: Arrian and Plutarch claimed that Alexander was speechless by this point, implying that this was an apocryphal story.
Sent 5: Diodorus, Curtius and Justin offered the more plausible story that Alexander passed his signet ring to Perdiccas, a bodyguard and leader of the companion cavalry, in front of witnesses, thereby nominating him.
Sent 6: Perdiccas initially did not claim power, instead suggesting that Roxane's baby would be king, if male; with himself, Craterus, Leonnatus, and Antipater as guardians.
Sent 7: However, the infantry, under the command of Meleager, rejected this arrangement since they had been excluded from the discussion.
Sent 8: Instead, they supported Alexander's half-brother Philip Arrhidaeus.
Sent 9: Eventually, the two sides reconciled, and after the birth of Alexander IV, he and Philip III were appointed joint kings, albeit in name only.

Sent 11: The satrapies handed out by Perdiccas at the Partition of Babylon became power bases each general used to bid for power.
Sent 12: After the assassination of Perdiccas in 321 BC, Macedonian unity collapsed, and 40 years of war between "The Successors" (Diadochi) ensued before the Hellenistic world settled into four stable power blocks: Ptolemaic Egypt, Selucid Mesopotamia and Central Asia, Attalid Anatolia, and Antigonid Macedon.
Sent 13: In the process, both Alexander IV and Philip III were murdered.
Question: What lead to both Alexander IV and Phillip III getting murdered?.
