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.

Example Input: Question: When was the home base of the Kansas City Chiefs built? Passage 1:SR 162 was codified as SSH 5E during the creation of the primary and secondary state highways in 1937, beginning at Primary State Highway 5 (PSH 5) and U.S. Route 410 in Puyallup, traveling through Orting and South Prairie to end at an intersection with a branch of PSH 5 southwest of Buckley. SSH 5E had a branch that traveled south from Orting to Electron that was removed from the state highway system in 1955. The highway traveled across the Puyallup River into Orting on the McMillin Bridge, which opened in 1934 as a concrete half-through truss bridge to save the Department of Highways a total of $826. SR 165 was established during the 1964 highway renumbering and was codified in 1970 as the replacement to SSH 5E. The western terminus, now at SR 410, was moved east to an interchange in Sumner after the completion of the Sumner Freeway in 1972. The McMillin Bridge was added to the National Register of Historic Places in 1982 as an example of a half-through truss bridge built with concrete instead of steel. The route of the highway has not seen a major revision since 1972; however, WSDOT repaved the roadway and added guardrails between Orting and Buckley in 2008. The deteriorating McMillin Bridge is being replaced by WSDOT with a newer, wider span over the Puyallup River scheduled to begin construction in 2014.
 Passage 2:The Chargers flew to Arrowhead Stadium for a Week 7 fight with their AFC West rival, the Kansas City Chiefs. In the first quarter, San Diego fell behind early with KC QB Damon Huard completing an 11-yard TD pass to TE Kris Wilson and a 21-yard TD pass to WR Eddie Kennison. In the second quarter, the Chargers got on the board with kicker Nate Kaeding making a 39-yard field goal, yet Kansas City would respond with an 11-yard run by RB Larry Johnson. Kaeding made a 31-yard field goal for San Diego to end the half. In the third quarter, both teams swapped touchdowns, as QB Philip Rivers threw a 1-yard TD pass to TE Antonio Gates, while Johnson got a 1-yard TD run. In the fourth quarter, RB LaDainian Tomlinson caught a 37-yard TD pass and then threw a 1-yard TD pass to TE Brandon Manumaleuna. Kansas City Chiefs kicker Lawrence Tynes was good on a 53-yard field goal to seal the win for Kansas City, dropping San Diego to 4–2.
 Passage 3:Empire Nightingale would appear to have crossed the Atlantic Ocean from the United States independently, as she does not appear as a member of a convoy until 27 June, when she departed Middlesbrough, Yorkshire as a member of Convoy EC 31. The convoy had departed from Southend, Essex the previous day and arrived at the Clyde on 1 July. She left the convoy at Oban, Argyllshire, departing on 3 July for Baltimore, Maryland, United States, which was reached on 22 July. Empire Nightingale departed Baltimore on 10 August for Halifax, Nova Scotia, Canada, arriving five days later. Carrying a cargo of steel, she departed on 21 August with Convoy HX 146, which arrived at Liverpool, Lancashire on 6 September. She left the convoy at Loch Ewe to join Convoy WN 177, which departed from Oban on 5 September and arrived at Methil, Fife on 8 September. Empire Nightingale then joined Convoy FS 589, which departed that day and arrived at Southend on 10 September. She left the convoy at Hull, Yorkshire on 10 September.

Example Input: Question: How long had the United Nations been in existence when Gross was appointed? Passage 1:On October 11, 1949, United States Secretary of State Dean Acheson appointed Gross as the United States' deputy delegate to the United Nations. Only two months later, the chief delegate, Warren Austin, took a leave of absence, and Gross took over as acting head of the U.S. delegation to the U.N. The major issue facing the United Nations at that time was the Soviet Union's proposal that, with the conclusion of the Chinese Civil War, the Communist People's Republic of China should replace the Republic of China on the United Nations Security Council. On January 13, 1950, the Soviet delegate, Jacov Malik, walked out of the Security Council in protest. Malik remained absent for several months, and as such the Soviet Union failed to exercise its veto power to block United Nations Security Council Resolution 82, which condemned North Korea at the beginning of the Korean War; on behalf of the U.S., Gross voted in favor of the resolution. In fall 1950, Warren Austin returned from his leave of absence, and Gross continued to serve as Austin's deputy until 1953.
 Passage 2:In 1908, she met John Dailey de Angeli, a violinist, known as Dai. They were married in Toronto on April 12,1910. The first of their six children, John Shadrach de Angeli, was born one year later. After living in many locations in the American and Canadian West, they settled in the Philadelphia suburb of Collingswood, New Jersey. There in 1921 Marguerite started to study drawing under her mentor, Maurice Bower. In 1922, Marguerite began illustrating a Sunday School paper and was soon doing illustrations for magazines such as The Country Gentleman, Ladies' Home Journal, and The American Girl, besides illustrating books for authors including Helen Ferris, Elsie Singmaster, Cornelia Meigs, and Dorothy Canfield Fisher. Her last child, Maurice Bower de Angeli, was born in 1928, seven years before the 1935 publication of her first book, Ted and Nina Go to the Grocery Store. The de Angeli family moved frequently, returning to Pennsylvania and living north of Philadelphia in Jenkintown, west of Philadelphia in the Manoa neighborhood of Havertown, on Carpenter Lane in Germantown, Philadelphia, on Panama Street in Center City, Philadelphia, in an apartment near the Philadelphia Art Museum, and in a cottage in Green Lane, Pennsylvania. They also maintained a summer cabin on Money Island in Toms River, New Jersey. Marguerite's husband died in 1969, eight months before their 60th wedding anniversary.
 Passage 3:The Tremp Basin evolved into a sedimentary depression with the break-up of Pangea and the spreading of the North American and Eurasian Plates in the Early Jurassic. Rifting between Africa and Europe in the Early Cretaceous created the isolated Iberian microplate, where the Tremp Basin was located in the northeastern corner in a back-arc basin tectonic regime. Between the middle Albian and early Cenomanian, a series of pull-apart basins developed, producing a local unconformity in the Tremp Basin. A first phase of tectonic compression commenced in the Cenomanian, lasting until the late Santonian, around 85 Ma, when Iberia started to rotate counterclockwise towards Europe, producing a series of piggyback basins in the southern Pre-Pyrenees. A more tectonically quiet posterior phase provided the Tremp Basin with a shallowing-upward sequence of marine carbonates until the moment of deposition of the Tremp Formation, in the lower section still marginally marine, but becoming more continental and lagoonal towards the top.

Example Input: Question: Who was the Emperor of the Byzantine Empire when Mehmed became Sultan for the first time? Passage 1:This is a list of campaigns personally led by Mehmed II or Sultan Mehmed the Conqueror (30 March 1432 – 3 May 1481) (Ottoman Turkish: محمد ثانى, Meḥmed-i s̠ānī; Turkish: II. Mehmet; also known as el-Fātiḥ, الفاتح, "the Conqueror" in Ottoman Turkish; in modern Turkish, Fatih Sultan Mehmet; also called Mahomet II in early modern Europe) was Sultan of the Ottoman Empire twice, first for a short time from 1444 to September 1446, and later from February 1451 to 1481. At the age of 21, he conquered Constantinople and brought an end to the Byzantine Empire, transforming the Ottoman state into an empire. Mehmed continued his conquests in Asia, with the Anatolian reunification, and in Europe, as far as Bosnia and Croatia. Mehmed II is regarded as a national hero in Turkey, and Istanbul's Fatih Sultan Mehmet Bridge is named after him.
 Passage 2:The British eventually recaptured Grappler from the French in September 1809 in the daring raid on Saint-Paul on the Île de Bourbon (now Réunion) from the nearby British-held island of Rodrigues. The British force consisted of a naval squadron under Commodore Josias Rowley and an Army force under Lieutenant Colonel Henry Sheehy Keating. The Army contingent, which consisted of 368 soldiers from the 1st Battalion of the 56th Regiment of Foot under the command Keating, embarked on HMS Nereide under Captain Robert Corbett, Otter under Captain Nesbit Willoughby and the East India Company schooner Wasp under Lieutenant Watkins. The rest of Rowley's squadron, the flagship , and the frigates under Captain Samuel Pym and HMS Boadicea under Captain John Hatley joined off St. Paul. These ships contributed an additional 236 seaman volunteers and Royal Marines to the assault. The entire invasion force then embarked on Nereide, as Corbett had experience with coastline of the Île Bonaparte coastline. On the early morning of 21 September the force seized the port of St. Paul. There they destroyed its defences and recovered a number of British vessels. Nereide and the landing party captured the 44-gun French frigate Caroline, and recovered Grappler as well as the East Indiamen (850 tons (bm) and pierced for 30 guns) and (820 tons (bm) and pierced for 26 guns). The expedition also captured three small merchant vessels (Fanny of 150 tons, and Tres Amis and Creole of 60 tons each), destroyed three others, and burnt one ship that was building on the stocks. The British did not sustain any loss on board the squadron or to their vessels. The British completed the demolition of the different gun and mortar batteries and of the magazines by evening and the whole of the troops, marines, and seamen returned on board their ships.
 Passage 3:From the beginning of the city's history as the western bank of Springfield, Irish families have resided in and contributed to the development of the civics and culture of Holyoke, Massachusetts. Among the first appellations given to the city were the handles "Ireland", "Ireland Parish", or "Ireland Depot", after the village was designated the 3rd Parish of West Springfield in 1786. Initially occupied by a mixture of Yankee English and Irish Protestant families, many of whom belonged to the Baptist community of Elmwood, from 1840 through 1870 the area saw a large influx of Irish Catholic workers, immigrants to the United States, initially from the exodus of the Great Famine. During that period Irish immigrants and their descendants comprised the largest demographic in Holyoke and built much of the early city's infrastructure, including the dams, canals, and factories. Facing early hardships from Anti-Irish sentiment, Holyoke's Irish would largely build the early labor movement of the city's textile and paper mills, and remained active in the national Irish nationalist and Gaelic revival movements of the United States, with the Holyoke Philo-Celtic Society being one of 13 signatory organizations creating the Gaelic League of America, an early 20th century American counterpart of Conradh na Gaeilge.
