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: 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.

Problem: Question: How long had Cape Colony been established when the Diocese of Grahamstown was created? Passage 1:Chen is currently the Malcolm K. Brachman Professor of Economics at Yale University. She previously taught at the London School of Economics, New York University, and the University of Chicago. After graduation from the University of California, San Diego, she became an assistant professor in economics at University of Chicago, a lecturer and reader at London School of Economics from 1999 to 2002. Thereafter, she joined New York University as an associate professor and she was promoted to professor of economics in 2005. In 2007, she became a professor of economics at Yale University and she is currently a Malcolm K. Brachman Professor of Economics at Yale University. Chen is an International Fellow of the Centre for Microdata Methods and Practice, an elected fellow of the Econometric Society, and an elected fellow of the Journal of Econometrics.
 Passage 2:In 1880, the Commission concluded that the solution of yellow fever causality must await further progress in the new science of bacteriology. Sternberg was soon sent to New Orleans to investigate the conflicting discoveries of Plasmodium malariae by Alphonse Laveran, and of Bacillus malariae by Edwin Klebs and Corrado Tommasi-Crudeli. His report (1881) declared that the Bacillus malariae had no part in the causation of malaria. The same year—simultaneously with Louis Pasteur—he announced the discovery of the pneumococcus, eventually recognized as the pathogenic agent of lobar pneumonia. He was the first in the United States to demonstrate the Plasmodium organism as cause of malaria (1885) and to confirm the causitive roles of the bacilli of tuberculosis and typhoid fever (1886). He was the first scientist to produce photomicrographs of the tubercule bacillus. He was also the earliest American pioneer in the related field of disinfection in which he began with experiments (1878) with putrefactive bacteria. This work was continued in Washington and in the laboratories of Johns Hopkins Hospital in Baltimore, under the auspices of the American Public Health Association. For his essay "Disinfection and Individual Prophylaxis against Infectious Diseases" (1886), later translated into several languages, he was awarded the Lomb Prize. He oversaw creation the US Army enlisted hospital corps ("medics") in 1887.
 Passage 3:In 1853, the territory was reduced by the creation of the Diocese of Grahamstown in the eastern parts of the Cape Colony and the Diocese of Natal in the Colony of Natal. In 1859, the Diocese of St Helena was created for Saint Helena and Ascension Island. In 1863, the Diocese of Bloemfontein was created, taking over all the territory north of the Orange River and the Drakensberg mountains. In 1866, J. Harries Thomas was archdeacon of Cape Town and H. Badnall, archdeacon of George; and N. J. Merriman, archdeacon of Bloemfontein (by then separated) was still a canon of Cape Town cathedral. The territory of the Cape Town diocese was further reduced in 1911 by the creation of the dioceses of George and Kimberley and Kuruman. Finally, in 2005 the diocese was divided into three, with the part to north of the city of Cape Town becoming the Diocese of Saldanha Bay and the part to the east of the city becoming the Diocese of False Bay.
