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 old was Bishop Loras when he traveled to France? Passage 1:The off-season brought a few changes to the coaching staff, as Notre Dame lost three assistant coaches to other opportunities: Kerry Cooks left the coaching staff to take the same position at the University of Oklahoma. Matt LaFleur departed to take the same position for the Atlanta Falcons of the NFL, and Tony Alford left the university to take the same position at Ohio State University.

Mike Sanford Jr. former Offensive Coordinator/Quarterbacks coach at Boise State accepted the same position on the coaching staff. Todd Lyght, a former All-American at Notre Dame and Cornerbacks coach at Vanderbilt, accepted the same position on the coaching staff.

 Passage 3:He was born in Montluel, in the département of Ain, France, 19 December 1799. He lived at St. Paul, Minnesota, 22 February 1857. He made his preparatory studies in the Petits séminaires of Meximieux (Ain) and Saint-Genis-l'Argentière (Rhône), his studies of philosophy at Alix (Rhône), and of theology in the seminary of Saint-Sulpice, Paris. He was ordained priest 20 December 1823, and soon was appointed vicar in the parish at Ferney, once the home of Voltaire, and eventually became its parish priest. He built there a new church and founded a boys' college with funds gathered on a tour through France. At this period, he revived the Catholic faith among many indifferent parishioners, who were made indifferent by the surviving influence of Descartes, and the proximity of the Protestant cantons of Switzerland. But Crétin longed for a larger field of activity; at one time he thought earnestly of going as a missionary to China. His perplexities in that regard were solved by the advent of Bishop Mathias Loras, first bishop of Dubuque, Iowa, who arrived in France in 1838 in search of priests for to evangelize his vast diocese. Crétin was one of the few who volunteered and on 16 August 1838, he secretly left his parish, embarked at Le Havre with Bishop Loras, and landed in New York in October of the same year. The winter of 1838-39 was spent in St. Louis, Missouri, and on his arrival in Dubuque, 18 April 1839, he was immediately appointed vicar-general of the new diocese. For over eleven years, he exercised his priestly ministry in these new regions, dividing his time between Dubuque, Prairie du Chien, Wisconsin, and the Winnebago Indians in the neighborhood of Fort Atkinson, in Winneshiek County, Iowa. Only once, in 1847, did he absent himself, when he made a trip to Europe in the interest of his missions. In 1850 St. Paul, Minnesota became the seat of a new diocese. Crétin was appointed its first bishop, and went to France, to be consecrated, 26 January 1851, at Belley by Bishop Devie, who had ordained him to the priesthood.
