Final answer:
The statement is false. The mutiny did not take place in San Julian, Argentina. It occurred during Ferdinand Magellan's expedition in the Philippines.
Step-by-step explanation:
The statement is False. San Julian, on Argentina's coast, is not where Magellan's men mutinied.
The mutiny actually took place during Ferdinand Magellan's expedition while he was in the Philippines.
The mutiny occurred because of a combination of factors, including a long and difficult voyage, disagreements with Magellan's leadership, and tension between the Spanish and indigenous peoples in the area.
