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: Who founded the school where Johann Gries studied law? Passage 1:After the political changes in 2000, Croatian cinema proved it could work in a completely free environment for the first time. As a result, at the beginning of this decade Croatian cinema flourishes again, and many critics write about "third golden era" (after the 1950s and 1960s). One of the most popular authors in the contemporary Croatian cinema is Vinko Brešan whose comedies Kako je počeo rat na mom otoku (How the War Started on My Island, 1997), and Maršal (Marshal Tito's Spirit, 1999) mix grotesque humor and political provocation. Brešan's war drama Svjedoci (Witnesses, based on a novel by Jurica Pavičić) was the first feature film from countries of former Yugoslavia which discussed the war crimes committed by "our guys", not the enemy. Film was screened in competition at the Berlin Film Festival in 2003. A Wonderful Night in Split (Ta divna splitska noć, 2004) by Arsen A. Ostojić received a nomination for the European Discovery EFA award, and Tu (Here, 2003) by Zrinko Ogresta was awarded at the Karlovy Vary Film Festival. Among other distinguished contemporary directors, internationally most recognized is Ognjen Sviličić, whose two films premiered at the Berlin Film Festival - Oprosti za kung fu (Sorry about Kung Fu, 2004) and Armin (2006). Armin was also Croatia's submission for the 2008 Academy Award, and although it didn't earn a nomination in the Best Foreign Language Film category, it did nevertheless receive the prestigious Best Foreign Film of 2007 Award given by the International Federation of Film Critics.
 Passage 2:Johann Diederich Gries was born into a prosperous Hamburg family, the fourth of his parents' seven recorded sons. Franz Lorenz Gries (1731-1803), his father, was a merchant and city senator. His mother Johanna also came from a mercantile background. He undertook an apprenticeship in business with a Hamburg wholesale merchant for three years between 1793 and 1795 which, he let it be known, was a miserable thing to have to do. After his elder brother Ludwig had intervened with their father on his behalf he was permitted to embark on a period of study in Law, enrolling at the University of Jena in October 1795. At Jena his naturally affability, his abundance of inoffensive humour and his exceptional talent as a piano player all combined to gain him ready access to the homes and social circles of the professors. He also acquired an extensive network of lifelong friend among his student contemporaries, such as Johann Georg Rist, Johann Friedrich Herbart, , also including a couple of years later Georg Arnold Heise, August Ludwig Hülsen and . At the home of the anatomist Justus Christian Loder he got to know Goethe and Schiller, Herder and Fichte. It was nevertheless striking that while his literary awareness and social circle developed rapidly, he approached his studies in jurisprudence with a marked absence of diligence. Early in 1797 he returned to Hamburg for a visit during which he renewed his friendship with Johann Albert Heinrich Reimarus and Friedrich Heinrich Jacobi. That summer he accompanied Caroline Schlegel and her daughter to Dresden where Schlegel was staying. That also gave him the opportunity to meet Schelling by whom he was much impressed. Around this time he also visited Freiberg where he was warmly received by . 
 Passage 3:Landowski had not held any public office until his election to the Assembly's 13th Milwaukee County district (the 13th & 21st Wards of the city of Milwaukee) in 1948 to succeed fellow Democrat William Nawrocki, who was not a candidate for re-election. After getting an absolute majority in a four-way primary election race, he won in the general election with 10,912 votes to 6071 for Republican John Froemming and 250 for People's Progressive Leo Jacobs. He was assigned to the standing committee on transportation. After an easy victory in the 1950 primary, he again defeated Froemming in the general election. He remained on the transportation committee, and was also assigned to the committee on commerce and manufacturers. He was an unsuccessful candidate in 1952's spring election for the Milwaukee County board of supervisors.
