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: How many times was the capital of Eastern Wu moved between 221 and when Sun Hao moved it? Passage 1:Following his arrest, Sandford was held in the Nevada Southern Detention Center. Due to his mental health conditions, Sandford was kept in solitary confinement and repeatedly put under suicide watch. On June 20, 2016, a complaint was filed with the United States District Court for the District of Nevada charging Sandford with committing an act of violence on restricted ground. Sandford appeared in a Nevada District Court on June 20, 2016, where he was charged with committing an act of violence on restricted ground. Sandford's public defender, Heather Fraley, argued that Sandford should be bailed to a halfway house given his lack of a criminal record, but he was denied bail by judge George Foley Jr. on the basis that he presented a flight risk and was a potential danger to the community. On June 29, a federal grand jury responded to an indictment filed by United States Attorney Daniel Bogden by charging Sandford with three felonies: two counts of being an illegal alien in possession of a firearm and one count of impeding and disrupting the orderly conduct of government business and official functions. Each charge carried a maximum sentence of 10 years' imprisonment and a fine of $250,000. U.S. Immigration and Customs Enforcement also issued a detainer against Sandford relating to an immigration violation.
 Passage 2:However, the Turkish Navy later changed its plan and opted for a fully equipped flight deck with the ski-jump ramp in front, after deciding to purchase F-35B STOVL aircraft. Turkey is a Level 3 partner in the Joint Strike Fighter program and the Turkish Air Force will get the F-35A CTOL version. The Turkish version of the LHD will be capable of operating up to 12 F-35Bs and 12 helicopters in "light aircraft carrier" configuration. The dimensions of the final design are: 232 meters (length), 32 meters (beam), 6.9 meters (draught), and 58 meters (height). Its displacement will be 24,660 tons (in "light aircraft carrier" mission configuration) or 27,079 tons (in "LHD" mission configuration). Its maximum speed will be 21.5 knots (in "light aircraft carrier" configuration) or 29 knots (in "LHD" configuration); while its maximum range will be 9000 miles at economical speed. It will have a 5,440 m² flight deck and a 990m² aviation hangar which can accommodate either 12 medium size helicopters or 8 CH-47F Chinook heavy-lift helicopters. (When the aviation hangar and the light cargo garage are unified, the ship can carry up to 25 medium size helicopters. Alternatively, the ship can carry up to 12 F-35B and 12 helicopters. Six more helicopters can be hosted on the flight deck of the ship.) Additionally, the ship will have a 1,880 m² light cargo garage for TEU containers and 27 Amphibious Assault Vehicles (AAV); a 1,165 m² dock which can host four Landing Craft Mechanized (LCM) or two Landing Craft Air Cushion (LCAC), or two Landing Craft Vehicle Personnel (LCVP); and a 1,410m² garage for heavy loads, which can host 29 Main Battle Tanks (MBT), Amphibious Assault Vehicles and TEU containers. The ship's crew will consist of 261 personnel: 30 officers, 49 NCOs, 59 leading seamen and 123 ratings.
 Passage 3:In 221, warlord Sun Quan moved the capital of Eastern Wu from Gong'an county, Jingzhou (northwest of present-day Gong'an county, Hubei) to È county (in present-day Ezhou City), and renamed È to Wuchang (literally prospering from military, regarding its logistics role of the military bases established before the Battle of Red Cliffs). Later in the year Cao Pi proclaimed himself the emperor of Cao Wei. Sun Quan declared independence in the following year, and started to build forts and palaces in Wuchang. Sun Quan proclaimed himself the emperor of Eastern Wu in 229, and moved the capital to Jianye. Sun Hao, the emperor of Eastern Wu between 264 and 280, moved the capital back to Wuchang in 265. In 589, the Wuchang commandery was abolished and the Wuchang county was transferred to a new commandery named Ezhou (headquartered in present-day Wuchang District), and remained in the administration since then.
