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.
One 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.

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

Now, solve this: Question: What town that the Dunckers returned to in Germany was the smaller of the two, Rostock or Bernau? Passage 1:Garron DuPree joined the group Eisley in 2005 at the age of 15, following the departure of their former bassist Jonathan Wilson. He is the cousin of the group's remaining members Chauntelle DuPree, Stacy DuPree, Weston DuPree, and Sherri DuPree. At the time of Garron's arrival with the Texas-based indie-pop band, they were entering a phase of heavy touring in support of their debut album Room Noises. Garron toured as Eisley's bassist beginning with the group's 2005 Yahoo sponsored "Who's Next?" tour, followed closely by 2005's Austin City Limits festival and closing out the year with Switchfoot's Nothing Is Sound tour. Eisley continued touring throughout 2006, visiting Australia in support of Taking Back Sunday, touring the United States with supporting band Dawes for their first major headlining tour, as well as touring Europe. Garron's bass work with Eisley began on their second full-length record, Combinations, and has remained the sole bassist on the remainder of Eisley's recordings to date. In 2013, Garron expanded his repertoire when he joined Say Anything as their bassist, replacing touring bassist Adam Siska. His bass work has been said to be inspired by Radiohead, Kent, Pink Floyd, the Beatles, and Matt Rubano, among others.
 Passage 2:In June 1998, Norwood released her second album Never Say Never. Boosted by the success of its number-one lead single "The Boy Is Mine", a duet with singer Monica, it facilitated Norwood in becoming a viable recording artist with media–crossing appeal. In total, the album sold 16 million copies worldwide and spawned seven singles, including Norwood's second number-one song, the Diane Warren-penned "Have You Ever?". Also in 1998, Norwood made her big screen debut in a supporting role in the slasher sequel, I Still Know What You Did Last Summer, which garnered her both a Blockbuster Entertainment Award and an MTV Movie Award nomination for Best Breakthrough Female Performance. The following year, she co-starred with Diana Ross in the telefilm drama Double Platinum about an intense, strained relationship between a mother and daughter. Both Norwood and Ross served as executive producers of the movie which features original songs from Never Say Never and Ross's Every Day Is a New Day (1999).
 Passage 3:The Dunckers returned to Germany in 1947, settling first in Rostock and later in Bernau, just outside Berlin. Home was now part of the Soviet occupation zone, relaunched in October 1949 as the German Democratic Republic a new separated German state with its political and economic structures modelled on those of the Soviet Union. By now chronically ill, Käte Duncker was no longer politically engaged, and never bothered to sign her communist party membership across to the new Socialist Unity Party ("Sozialistische Einheitspartei Deutschlands" / SED), which, following its creation in April 1946, quickly became the ruling party in a new kind of German one-party dictatorship. Nevertheless, on 2 June 1948 she wrote to her old friend and comrade, Wilhelm Pieck, imploring him to use his personal influence to find out what had happened to her younger son, . Like Wolfgang Duncker, Wilhelm Pieck had moved to Moscow in 1935: unlike Wolfgang, he had survived, and was now a top German politician in the Soviet occupation zone. (In 1949 he became East Germany's first president.) On 10 November 1948 the Dunckers received a message from the Red Cross informing them that their younger son had died in on 20 November 1942. According to a detailed report submitted by his wife to the Central Committee of the exiled German Communist Party in Moscow on 22 September 1939, Wolfgang had been arrested on 21 March 1938 and interrogated. He had been forced, after four months, to sign a false confession, and then taken to a concentration camp where conditions had been grim. (Wolfgang's widow had survived the war, working in a (military) tank factory, and returned to the Soviet occupation zone in 1945 accompanied by her second husband and her two surviving children.)
