You will be given a definition of a task first, then some input of the task.
In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.

Question: When was the flag that the King pulled first created? Passage 1:Before the ceremony began, King Edward VIII, present in his capacity as king of Canada, inspected the guard of honour, was introduced to the honoured guests, and spent approximately half an hour speaking with veterans in the crowd. Two Royal Air Force and two French Air Force squadrons flew over the monument and dipped their wings in salute. The ceremony itself began with prayers from chaplains representing the Church of England, the United Church of Canada, and the Roman Catholic Church. Ernest Lapointe, Canadian Minister of Justice, spoke first, followed by Edward VIII who, in both French and English, thanked France for its generosity and assured those assembled that Canada would never forget its war missing and dead. The King then pulled the Royal Union Flag from the central figure of Canada Bereft and the military band played the Last Post. The ceremony was one of the King's few official duties before he abdicated the throne. The pilgrimage continued, and most participants toured Ypres before being taken to London to be hosted by the British Legion. One-third of the pilgrims left from London for Canada on 1 August, while the majority returned to France as guests of the government for another week of touring before going home.
 Passage 2:McClean made his first start for Sunderland in their 1–0 victory over Manchester City on 1 January 2012, and scored his first senior goal for the Black Cats in a 4–1 win against Wigan Athletic two days later; on 8 January, he scored and assisted Sebastian Larsson in a 2–0 win at Peterborough United in the third round of the FA Cup. McClean provided the assist for Stéphane Sessègnon's opening goal in Sunderland's 2–0 victory over Swansea City on 21 January, and got another assist in the equalising goal for Fraizer Campbell in the next round of the cup against Middlesbrough on 29 January. Ahead of the replay for that fixture, Middlesbrough manager Tony Mowbray used McClean as an example for young players to follow. McClean turned provider again in Sunderland's 3–0 victory over Norwich City, assisting Sessègnon's goal, then scored the only goal in a win over Stoke City on 4 February in snowy conditions at the Britannia Stadium. A week later, he opened the scoring in Sunderland's 2–1 home loss to Arsenal after Per Mertesacker injured himself. On 23 March, Sunderland announced that McClean had signed a new contract intended to force him to stay at the club until the summer of 2015. A day later, he helped them to a 3–1 victory over relegation-threatened Queens Park Rangers by assisting the opening goal for Nicklas Bendtner and later scoring by himself. McClean won Sunderland's Young Player of the Year Award, at the end of the 2011–12 season.
 Passage 3:After stopping at Madeira and the Cape Colony, the Investigator reached Australia in December 1801. It sailed along the south coast, through Bass Strait, and north along the east coast to overwinter at Port Jackson. It then sailed north up the east coast, rounding the Cape York Peninsula and entering the Gulf of Carpentaria. The ship by then being in extremely poor condition, the survey was broken off and the Investigator was sailed to Koepang, Timor. Many members of the crew became sick with dysentery there, and Flinders took the decision to return to Port Jackson as quickly as possible. They sailed southwards well west of the west coast of Australia, then east along the south coast, arriving back at Port Jackson in June 1802. The Investigator was condemned, and Flinders sailed for England as passenger on the Porpoise, there to ask for a new ship. Though initially inclined to remain at Port Jackson with some of the other naturalists, ultimately Allen chose to board the Porpoise. On 17 August the Porpoise was wrecked on Wreck Reef. Everyone on board was marooned on a sandbank for six weeks while Flinders sailed the ship's cutter back to Port Jackson to seek help. When help arrived it was in the form of two ships, one of which would return to Port Jackson, while the other was en route to China. Allen elected to sail to China. From there he took a passage to England on the Henry Addington. Arriving at Brighton on 8 August 1804, Allen made his way to London, where he gave to Banks the first eye-witness account of the voyage, including breaking the news of the death at Port Jackson of the gardener Peter Good.
