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.

Reason: The question refers to the 704th unit and task about war which is decribed by Passage 1.

Now, solve this instance: Question: Who was the head coach for the Cowboys when the 49ers lost the first NFC Championship Game against them? Passage 1:Watters played for ten seasons in the NFL with San Francisco, Philadelphia, and Seattle. He was selected by San Francisco in the second round of the 1991 NFL Draft, but sat out the entire 1991 season with injuries. He started at running back for the 49ers during the next three seasons and San Francisco's offense led the NFL in scoring and yardage each year. The 49ers reached the NFC Championship Game in 1992 and 1993, falling both times to the Dallas Cowboys, before finally vanquishing Dallas in the 1994 NFC title game on their way to a Super Bowl championship. In a January 1994 divisional playoff, Watters set an NFL postseason record with five rushing touchdowns in the game, as the 49ers trounced the New York Giants 44-3. In Super Bowl XXIX the following season, Watters scored three touchdowns in San Francisco's 49-26 victory over the San Diego Chargers, tying a Super Bowl mark shared by fellow 49ers Roger Craig and Jerry Rice, and later matched by Terrell Davis of the Denver Broncos.
 Passage 2:Hamilton Fish (August 3, 1808September 7, 1893) was an American politician who served as the 16th Governor of New York from 1849 to 1850, a United States Senator from New York from 1851 to 1857 and the 26th United States Secretary of State from 1869 to 1877. Fish is recognized as the "pillar" of the presidency of Ulysses S. Grant and considered one of the best U.S. Secretaries of State by scholars, known for his judiciousness and efforts towards reform and diplomatic moderation. Fish settled the controversial Alabama Claims with Great Britain through his development of the concept of international arbitration. Fish kept the United States out of war with Spain over Cuban independence by coolly handling the volatile Virginius Incident. In 1875, Fish initiated the process that would ultimately lead to Hawaiian statehood, by having negotiated a reciprocal trade treaty for the island nation's sugar production. He also organized a peace conference and treaty in Washington D.C. between South American countries and Spain. Fish worked with James Milton Turner, America's first African American consul, to settle the Liberian-Grebo war. President Grant said he trusted Fish the most for political advice.
 Passage 3:He began playing with an amateur baseball club in East St. Louis, Illinois in 1883, and later that year, he began playing professionally with a team in Evansville, Indiana. He continued with the team into the 1884 season when he was signed by the St. Louis Browns of the American Association (AA), and made his Major League Baseball debut on May 29, 1884. He played just five games for the Browns, and was released after collecting four hits in 20 at bats for a .200 batting average. He returned to Evansville, but was soon signed by the Washington Nationals of the AA, and he was playing for the team in the latter part of July 1884. On August 2, the Evening Star opined that the Nationals' outfield, now consisting of Goldsby, Frank Olin, and Willie Murphy, had made a significant improvement. Despite the praise, and good play, he was released from the teams after playing in six games and a .375 batting average. He later appeared in 11 games for the Richmond Virginians, and was released from the team in September. After the AA season had completed, he was again playing for Evansville.
