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.
One example: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage 1: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lô during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,
. Passage 2: John Ford (1894–1973) was an American film director whose career spanned from 1913 to 1971. During this time he directed more than 140 films. Born in Maine, Ford entered the filmmaking industry shortly after graduating from high school with the help of his older brother, Francis Ford, who had established himself as a leading man and director for Universal Studios. After working as an actor, assistant director, stuntman, and prop man – often for his brother – Universal gave Ford the opportunity to direct in 1917. Initially working in short films, he quickly moved into features, largely with Harry Carey as his star. In 1920 Ford left Universal and began working for the Fox Film Corporation. During the next ten years he directed more than 30 films, including the westerns The Iron Horse (1924) and 3 Bad Men (1926), both starring George O'Brien, the war drama Four Sons and the Irish romantic drama Hangman's House (both 1928 and both starring Victor McLaglen). In the same year of these last two films, Ford directed his first all-talking film, the short Napoleon's Barber. The following year he directed his first all-talking feature, The Black Watch.
. Passage 3: Since the late 1970s, the central part of NYU is its Washington Square campus in the heart of Greenwich Village. Despite being public property, and expanding the Fifth Avenue axis into Washington Square Park, the Washington Square Arch is the unofficial symbol of NYU. Until 2008, NYU's commencement ceremony was held in Washington Square Park. However, due to space constraints, ceremonies are now held at the Yankee Stadium. Important facilities at Washington Square are the Elmer Holmes Bobst Library, designed by Philip Johnson and Richard Foster, who also designed several other structures, such as Tisch Hall, Meyer Hall, and the Hagop Kevorkian Center. When designing these buildings Johnson and Foster also set up a master plan for a complete redesign of the NYU Washington Square campus. However, it was never implemented. Other historic buildings include the Silver Center (formerly known as "Main building"); the Brown Building of Science; Judson Hall, which houses the King Juan Carlos I of Spain Center; Vanderbilt Hall, the historic townhouse row on Washington Square North; The Grey Art Gallery at 100 Washington Square East, housing the New York University art collection and featuring museum quality exhibitions; the Kaufman Management Center; and the Torch Club – the NYU dining and club facility for alumni, faculty, and administrators. Just a block south of Washington Square is NYU's Washington Square Village, housing graduate students and junior and senior faculty residences in the Silver Towers, designed by I. M. Pei, where an enlargement of Picasso's sculpture Bust of Sylvette (1934) is displayed.

Explanation: The question refers to the 704th unit and task about war which is decribed by Passage 1.

Now, solve this: Question: How old was Firlej when the Polish-Teutonic War started? Passage 1:The Packers started the game missing two key players of their defense, with injured cornerback Charles Woodson (tied for 7th in the NFL with 4 interceptions) and pass-rushing end Kabeer Gbaja-Biamila (tied for 6th in the NFL with 9.5 sacks) on the inactive list. In the first quarter, Green Bay took the early lead as rookie kicker Mason Crosby completed a 47-yard field goal. On the first play of the Cowboys opening drive, Al Harris stripped the ball from Terrell Owens and side judge Laird Hayes signaled Green Bay ball, but head linesman Derick Bowers overruled him. The only option for Mike McCarthy to challenge on the play, since the whistle was blown, was whether it was a reception – the strip could not be reviewed. The replay upheld the reception and Dallas retained possession. Nick Folk completed a 26-yard field goal to tie the game. Folk also completed a 51-yard field goal, and QB Tony Romo threw a 3-yard TD pass to WR Patrick Crayton. The Packers would end the first quarter with rookie RB Ryan Grant running for a 62-yard touchdown. In the second quarter, Dallas responded with Romo completing a 26-yard TD pass to TE Anthony Fasano and a 10-yard TD pass to WR Terrell Owens. Brett Favre left the game in the second quarter after he hit his right elbow on the helmet of a blitzing Cowboys DB Nate Jones. The throw led to Favre's second interception. Packers quarterback Aaron Rodgers took over for the Packers next series and led the offense on a 74-yard drive, capping it off with an 11-yard TD pass to WR Greg Jennings.
 Passage 2:Syphilitic aortitis is inflammation of the aorta associated with the tertiary stage of syphilis infection. SA begins as inflammation of the outermost layer of the blood vessel, including the blood vessels that supply the aorta itself with blood, the vasa vasorum. As SA worsens, the vasa vasorum undergo hyperplastic thickening of their walls thereby restricting blood flow and causing ischemia of the outer two-thirds of the aortic wall. Starved for oxygen and nutrients, elastic fibers become patchy and smooth muscle cells die. If the disease progresses, syphilitic aortitis leads to an aortic aneurysm. Overall, tertiary syphilis is a rare cause of aortic aneurysms. Syphilitic aortitis has become rare in the developed world with the advent of penicillin treatments after World War II.
  Passage 3:In 1454 the Prussian Confederation rebelled against the Teutonic Knights and formally asked the Polish King Casimir IV Jagiellon to incorporate Prussia into the Kingdom of Poland as a fief. This marked the beginning of the Thirteen Years' War (1454-66) between the State of the Teutonic Order and the Crown of the Kingdom of Poland. While Königsberg's three towns initially joined the rebellion, Altstadt and Löbenicht soon rejoined the Teutonic Knights and defeated Kneiphof in 1455. Grand Master Ludwig von Erlichshausen fled from the crusaders' capital at Castle Marienburg to Königsberg in 1457; the city's magistrate presented Erlichshausen with a barrel of beer out of compassion. When western Prussia was transferred to victorious Poland in the Second Peace of Thorn (1466), which ended the Thirteen Years' War, Königsberg became the new capital of the reduced monastic state, which became a fief of the Crown of the Polish Kingdom. The grand masters took over the quarters of the marshal. During the Polish-Teutonic War (1519–1521), Königsberg was unsuccessfully besieged by Polish forces led by Grand Crown Hetman Mikołaj Firlej.
