Problem: 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: Who was the mayor of New York City the year Carroll left the city to return to Maryland? Passage 1:In Roman times, it was a village in the province of Moesia, first mentioned in 169. After the decline of the Roman Empire, the town turned out to be located at the northern border of the Byzantine Empire. In 1059, it was named Nicopolis, Greek for "City of Victory". During most of the Middle Ages, it was part of the Bulgarian Empire from its foundation in 681. After the fall of Tarnovo in 1393, the last Bulgarian Tsar Ivan Shishman defended what remained of the Empire from the fortress of Nikopol, where he was captured after the town was conquered by the Ottomans in 1395. Nikopol is therefore sometimes considered the capital of Bulgaria during these two years. It was the site of the Battle of Nicopolis, the last large-scale crusade of the Middle Ages, in 1396. At the fortress of Nicopolis, the united armies of Christian Europe headed by Hungarian king Sigismund and various French knights were defeated by the Ottomans under Bayezid I and his Serbian vassal Stefan Lazarević.
 Passage 2:After finishing schooling, Carroll worked as a student lawyer for the law office of Brown and Brune in Baltimore. He was admitted to the bar in 1851. Carroll practiced law in Maryland from 1854 until 1858. He ran as a Howard County Democratic candidate for the state General Assembly in 1854, (shortly after the separation of the former Howard or Western District of Anne Arundel County and the "erection"/establishment of Howard as the 22nd of the state's 23 counties), however losing to his opponent from the newly-dominant "Know Nothing" Party (also known as the American Party) during the political crises of the 1850s. Carroll then moved to New York City and while there, accepted a position as deputy clerk and United States Commissioner in the office of the clerk of the United States District Court. He stayed there until 1861, at the outbreak of the Civil War, when he returned to Maryland, where he then remained the rest of his life. When he returned to Maryland, Carroll purchased the "Doughoregan Manor", historic family estate in Howard County, near Ellicott City from his older brother Charles Carroll.

Winner spent two seasons with the Crew before being waived on June 1, 1998. In June 1998, he spent time with the New England Revolution. At the beginning of July, he spent a few games as a backup with the Chicago Fire. At the end of July, the Miami Fusion signed Winner to a short-term contract after injuries hit the Fusion goalkeeper corps. He finished the season with the Worcester Wildfire of the USL A-League. On February 7, 1999, the Colorado Rapids selected Winner in the second round (twentieth overall) of the 1999 MLS Supplemental Draft. The Rapids released him, but the Kansas City Wizards signed him in March after Tony Meola and Chris Snitko were both injured during the pre-season. On March 20, 2000, Winner signed with the Connecticut Wolves of the USL A-League. In August 2000, he moved to the Atlanta Silverbacks where he played nine games. On September 4, 2000, the New England Revolution signed him for the remainder of the season. In 2001, Winner joined the Indiana Blast of the USL A-League. In June, the Miami Fusion called him up as a backup goalkeeper.
