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 companies have offices in the tallest building in Dubai? Passage 1:Dubai, the largest city in the United Arab Emirates, is home to many modern high-rises, 108 of which stand taller than . The tallest building in Dubai is the Burj Khalifa, which rises and contains 163 floors. The tower has stood as both the tallest building in the world and the tallest man-made structure of any kind in the world since its completion in January 2010. The second-tallest building in Dubai is the Marina 101, which also stands as the world's second tallest residential skyscraper. The skyscrapers of Dubai are, for the most part, clustered in three different locations. The land along E 11 Road was the first to develop, followed by the Dubai Marina neighborhood and the Business Bay district.
 Passage 2:Montenegro has no currency of its own. As a constituent republic of the Socialist Federal Republic of Yugoslavia following World War II, and later of the Federal Republic of Yugoslavia, the Yugoslav dinar was the official currency in Montenegro. In November 1999, the government of Montenegro unilaterally designated the Deutsche Mark as its co-official currency with the dinar, and on 1 January 2001 the dinar officially ceased to be a legal tender in Montenegro. When the euro was introduced and the Deutsche Mark yielded, Montenegro followed suit and began using the euro as well, with no objection from the European Central Bank (ECB). The European Commission and the ECB have since voiced their discontent over Montenegro's unilateral use of the euro on several occasions.” A statement attached to their Stabilisation and Association Agreement with the EU read: "unilateral introduction of the euro was not compatible with the Treaty." The EU insists on the strict adherence to convergence criteria (such as spending at least 2 years in the ERMII system) which are not negotiable before euro adoption, but have not intervened to stop the unilateral adoption of the euro by Montenegro in 2002.
 Passage 3:In the 18th century, England was famous for its woollen and worsted cloth. That industry, centred in the east and south in towns such as Norwich, jealously protected their product. Cotton processing was tiny: in 1701 only of cottonwool was imported into England, and by 1730 this had fallen to . This was due to commercial legislation to protect the woollen industry. Cheap calico prints, imported by the East India Company from Hindustān (India), had become popular. In 1700 an Act of Parliament passed to prevent the importation of dyed or printed calicoes from India, China or Persia. This caused demand to switch to imported grey cloth instead—calico that had not been finished—dyed or printed. These were printed with popular patterns in southern England. Also, Lancashire businessmen produced grey cloth with linen warp and cotton weft, known as fustian, which they sent to London for finishing. Cottonwool imports recovered though, and by 1720 were almost back to their 1701 levels. Again the woollen manufacturers, in true protectionist fashion, claimed that the imports were taking jobs away from workers in Coventry. The Woollen, etc., Manufactures Act 1720 was passed, enacting fines against anyone caught wearing printed or stained calico muslins. Neckcloths and fustians were exempted. The Lancashire manufacturers exploited this exemption; coloured cotton weft with linen warp were specifically permitted by the 1736 Manchester Act. There now was an artificial demand for woven cloth.

Question: What was the age of the oldest member (besides Stephanie) of the group representing Armenia in the Eurovision Song Contest 2015? Passage 1:Chemokine receptors are G protein-coupled receptors containing 7 transmembrane domains that are found predominantly on the surface of leukocytes, making it one of the rhodopsin-like receptors. Approximately 19 different chemokine receptors have been characterized to date, which share many common structural features; they are composed of about 350 amino acids that are divided into a short and acidic N-terminal end, seven helical transmembrane domains with three intracellular and three extracellular hydrophilic loops, and an intracellular C-terminus containing serine and threonine residues that act as phosphorylation sites during receptor regulation. The first two extracellular loops of chemokine receptors are linked together by disulfide bonding between two conserved cysteine residues. The N-terminal end of a chemokine receptor binds to chemokine(s) and is important for ligand specificity. G-proteins couple to the C-terminal end, which is important for receptor signaling following ligand binding. Although chemokine receptors share high amino acid identity in their primary sequences, they typically bind a limited number of ligands. Chemokine receptors are redundant in their function as more than one chemokine is able to bind to a single receptor.
 Passage 2:A return to the Formula Three Euroseries beckoned for van Dam, with a 2009 campaign for Kolles & Heinz Union, the new team set up by Colin Kolles and Werner Heinz. However, the partnership was not to last, as after the rounds at Lausitz, van Dam parted company with the team. In four races, his best finish was eighteenth during the season-opening race at Hockenheim. Van Dam drove in the 24-hour endurance races at the Nürburgring and at Spa, before agreeing to drive the car of PSV Eindhoven in the Superleague Formula series. He replaced Dominick Muermans in the car, with the team lying eighteenth in the overall standings. However, he returned to the Euroseries, for the Barcelona rounds, rejoining his former team SG Formula.
 Passage 3:In February 2015 she was announced as a member of the music group Genealogy (made up of singers from Armenia and the Armenian diaspora) that represented Armenia in the Eurovision Song Contest 2015. Stephanie Topalian represents the Asian continent in the formation whereas the Ethiopian Vahe Tilbian represents Africa, the American Tamar Kaprelian the American continent, the French Essaï Altounian the European continent and the Australian Mary-Jean O'Doherty Basmadjian Oceania and Inga Arshakyan Armenia. The super group sang "Face the Shadow", the Armenian entry to the 2015 Eurovision Song Contest in Vienna, Austria. She became an Armenian citizen along with the other foreign members of Genealogy on 28 April 2015 after being given Armenian passports by President Serzh Sargsyan.

Question: Who was the ruler of the State of the Teutonic Order when the Prussian Confederation rebelled? 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: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.
 Passage 3: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.
