You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

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.

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

New input: Question: What is the difference in population between the city where Bricher began his career as a businessman and the city where he moved in 1868? Passage 1:Tasker was a color commentator for CBS football telecasts (with Andrew Catalon (play-by-play) and Steve Beuerlein (the other color commentator) starting in 2014). CBS did not renew his contract at the end of the 2018 season. He also does color commentary for the local broadcasts of Bills pre-season games, teaming with either his former broadcast partner Andrew Catalon or Rob Stone. He is also the spokesperson for the West Herr Auto Group. Tasker was on the sidelines with Jim Nantz and Phil Simms during the playoffs until 2013. He also worked with Don Criqui (Criqui, himself a Buffalo native, and Tasker were assigned to the majority of Bills games from 1999 to 2005) and was best known working with Gus Johnson in 1998, week 13 in 1999, week 5 in 2004, and from 2005 to 2010. Johnson left for FOX Sports the following year. He and Johnson called the David Garrard game winning Hail Mary touchdown pass for the Jacksonville Jaguars' win over the Houston Texans in 2010. CBS dismissed Tasker prior to the 2019 season as they chose not to renew his contract.
 Passage 2:Bricher was born in Portsmouth, New Hampshire. He was educated in an academy at Newburyport, Massachusetts. He began his career as a businessman in Boston, Massachusetts. When not working, he studied at the Lowell Institute. He also studied with Albert Bierstadt, William Morris Hunt, and others. He attained noteworthy skill in making landscape studies from nature, and after 1858 devoted himself to the art as a profession. He opened a studio in Boston, and met with some success there. In 1868 he moved to New York City, and at the National Academy of Design that year he exhibited “Mill-Stream at Newburyport.” Soon afterward he began to use watercolors in preference to oils, and in 1873 was chosen a member of the American Watercolor Society. In the 1870s, he primarily did maritime themed paintings, with attention to watercolor paintings of landscape, marine, and coastwise scenery. He often spent summers in Grand Manan, where he produced such notable works as Morning at Grand Manan (1878). In 1879, Bricher was elected into the National Academy of Design as an Associate member.
 Passage 3:The 1943 Atlantic hurricane season marked the first deliberate reconnaissance aircraft flights into tropical cyclones. The season officially lasted from June 16 to October 31, which was, at the time, considered the most likely period for tropical cyclone formation in the Atlantic Ocean. A total of ten storms from 1943 are listed in the Atlantic hurricane database, and an eleventh system that affected Florida and Georgia has been identified as a probable tropical depression. The first system of the year, dubbed the "Surprise hurricane", caused severe damage throughout Texas and Louisiana in June, partially because information about its approach was censored in the fray of World War II; the storm caused 19 deaths and $17 million in damage. A major hurricane in mid-August produced hurricane-force winds in Bermuda, and several other tropical cyclones throughout the year resulted in strong winds there. In September, a hurricane impacted the western Gulf Coast of the United States, then a tropical storm struck the Mid-Atlantic. The two storms resulted in $419,000 and $20,000 in damage, respectively; one death was attributed to the latter system. In mid-October, a strong hurricane resulted in flooding and damage to crops throughout the Caribbean; after becoming post-tropical, it contributed to moderate impacts across Nova Scotia.
