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 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.

Q: Question: Which founder of the railroad which eventually became the Virginian Railway was born first? Passage 1:Until 1548 the interior of the building would have resembled the interior of any medieval church, with a rood screen separating the chancel from the nave (projections to support the screen can still be seen on the piers either side of the nave on the west side of the crossing). It is not known if there were ever wall paintings, but successive generations of plaster and whitewash over the last five centuries will have long concealed any which may have existed. In 1548 Edward VI ordered the destruction of all aspects of ‘Popish Superstition’ within the churches of his realm. The Jerseymen, strongly influenced by Huguenot immigrants fleeing persecution in France, carried out the King's orders with zeal, and all altars, fonts, holy water stoups and piscinas were removed, the rood screen was dismantled, the stained glass smashed and all but one bell was taken from the tower. A huge triple-decker pulpit was erected in the crossing and pews were arranged around it. Seven galleries were built, including one reserved for smokers. In spite of the return of Anglican worship in the 17th century, the church continued in this state until the 1860s, by which time it had fallen into considerable disrepair. A major project of restoration was undertaken to repair and re-order the building after the conventions of the Church of England. The pulpit was replaced by a much more modest affair at the north west corner of the crossing, the galleries were broken up, the pews were taken out and replaced by a new set facing the restored altar at the east end. The original font, left in the churchyard, was given to Grouville Parish Church and a new font installed. An extension was made to the west end of the Nave, and a new gallery was installed there and in the South Transept. New choir stalls were erected in the chancel. In 1930 these were replaced by another new set as a memorial to Charles George Renouf, a Jurat of the Royal Court (the stalls they replaced were given to St Andrew's Church). At the same time the level of the Chancel floor was raised. The South Chapel was re-ordered in 1952 as a memorial to Matthew le Marinel, Rector of St Helier and Dean of Jersey during the German Occupation (1940–45), and again in 2004 to make it more ‘user-friendly’. In 1997 a glass screen was erected to separate the nave extension from the rest of the church to create a narthex (reception area), new glass doors were installed at the west end and the font was moved from the west end to its original position by the North Door.
 Passage 2:Early in the 20th century, William Nelson Page, a civil engineer and coal mining manager, joined forces with a silent partner, industrialist financier Henry Huttleston Rogers (a principal of Standard Oil and one of the wealthiest men in the world), to develop the Deepwater Railway, a modest 85-mile long short line railroad to access untapped bituminous coal reserves in some of the most rugged sections of southern West Virginia. When Page was blocked by collusion of the bigger railroads, who refused to grant reasonable rates to interchange the coal traffic, he did not quit. As he continued building the original project, to provide their own link, using Rogers' resources and attorneys they quietly incorporated another intrastate railroad in Virginia, the Tidewater Railway. In this name, they secured the right-of-way needed all the way across Virginia to reach Hampton Roads, where a new coal pier was erected at Sewell's Point.
 Passage 3:Austria was subsumed into Germany in 1938. Germany had been governed by Nazis since 1933, according to the twin tenets of populism through the ages: hope and hatred. The hatred was focused on Communists and Jews, and took increasingly sinister and destructive forms. Clara Katharina Pollaczek was subject to antisemitic persecution. She may have owed her survival to her possession of a Czechoslovak passport, acquired as a result of the marriage to Pollaczek. Two days after German troops were welcomed by cheering crowds into Vienna marking Austria's incorporation into Nazi Germany, she crossed to Prague where she lived for a while. When, in 1939, the Germans completed their occupation of Czechoslovakia, she was visiting friends in Switzerland. She stayed in Switzerland, receiving financial support from relatives, till war ended in 1945. During this period she became a Roman Catholic. (The last practicing Jew in her family had been her grandfather.) In 1945 she joined her son Karl who had ended up in Gillingham in England, but he was married with children: the home was cramped and, unlike her younger son, Clara did not feel settled in England. It was her brother, the lawyer Otto Loeb, who organised her return to Vienna in 1948.
