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.

Let me give you an 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.

Question: In which country is the island located that Langston Jr. worked on until 1962? Passage 1:Langston worked on a number of different reptiles and amphibians in his long career, beginning with the 1950 description (with J. Willis Stovall) of the theropod dinosaur Acrocanthosaurus. Langston was hired by the National Museum of Canada in 1954 to replace Charles M. Sternberg, and worked in western Canada and on Prince Edward Island until 1962. One of his major finds, with Loris Russell, was the rediscovery of Sternberg's Scabby Butte Pachyrhinosaurus bonebed. Langston, along with a small team of fieldworkers, excavated the Scabby Butte bonebed in 1957, securing several skulls and several hundred bones there. He then went on in 1963 to the University of Texas, where in 1969 he became the second director of the Vertebrate Paleontology Laboratory, where he worked on many projects, including work on Cretaceous vertebrates from Big Bend National Park. Finds that he and his students worked on include the giant pterosaur Quetzalcoatlus and a variety of Permian and Mesozoic reptiles. He retired in 1986, but continued to be active in the field. In 2007, Langston was the twentieth recipient of the Society of Vertebrate Paleontology's A. S. Romer-G. G. Simpson Medal, the highest honor of the society.
 Passage 2:The early history of United States space policy is linked to the US–Soviet Space Race of the 1960s. The National Aeronautics and Space Act creating NASA was passed in 1958, after the launch of the Soviet Sputnik 1 satellite. Thereafter, in response to the flight of Yuri Gagarin as the first man in space, Kennedy in 1961 committed the United States to landing a man on the Moon by the end of the decade. Although the costs of the Vietnam War and the programs of the Great Society forced cuts to NASA's budget as early as 1965, the first Moon landing occurred in 1969, early in Richard Nixon's presidency. Under the Nixon administration NASA's budget continued to decline and three of the planned Apollo Moon landings were cancelled. The Nixon administration approved the beginning of the Space Shuttle program in 1972, but did not support funding of other projects such as a Mars landing, colonization of the Moon, or a permanent space station.
 Passage 3:Strout's first novel, Amy and Isabelle (1998) met with widespread critical acclaim, became a national bestseller, and was adapted into a movie starring Elisabeth Shue. Her second novel, Abide with Me (2006), received critical acclaim but ultimately failed to be recognized to the extent of her debut novel. Two years later, Strout wrote and published Olive Kitteridge (2008), to critical and commercial success grossing nearly $25 million with over one million copies sold as of May 2017. The novel won the 2009 Pulitzer Prize for Fiction. The book was adapted into a multi Emmy Award-winning mini series and became a New York Times bestseller. Five years later, she published The Burgess Boys (2013), which became a national bestseller. My Name Is Lucy Barton (2016) was met with international acclaim and topped the New York Times bestseller list. Lucy Barton later became the main character in Strout's 2017 novel, Anything is Possible. A sequel to Olive Kitteridge, titled Olive, Again, was published in 2019.
