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: How many albums had Pink Floyd released before Ummagumma? Passage 1:In 2012, Sonenclar auditioned for the second season of The X Factor USA with the song "Feeling Good" by Anthony Newley and Leslie Bricusse (famously covered by Nina Simone among others). Sonenclar received a standing ovation from all four judges (L.A. Reid commented "You may be 13, but your soul is old!"; Simon Cowell awarded her "4,833 yes'"), and she advanced to the next round. After her successful initial audition, she advanced through the first day of X Factor's "bootcamp," where she sang "Pumped Up Kicks" with Beatrice Miller. Of the 120 contestants who auditioned at bootcamp that day, she was among the sixty or so asked to continue on. At the end of bootcamp, she was chosen to be one of the six contestants in the "teens" category who were invited to perform at the "judges' houses" stage of the competition. She performed the song "Brokenhearted" for the "teens" category mentor, Britney Spears, and Spears' guest judge will.i.am. Both Spears and will.i.am responded positively to her performance; will.i.am remarked appreciatively that she was "possessed." Sonenclar next advanced into the Top 16 round, where she performed "Good Feeling", then the Top 13 round, where she performed "It Will Rain". When Sonenclar reached the Top 12 round—where she performed "My Heart Will Go On"—it was revealed that she was the second-most-voted for person in the competition so far, behind only Tate Stevens, a distinction she achieved again after advancing to the Top 10 round.
 Passage 2:At the 2005 state election, Hames was re-elected to parliament as the member for the seat of Dawesville (taking in the southern suburbs of Mandurah). He replaced the retiring Liberal member, Arthur Marshall. Hames was included in the shadow cabinet immediately after the election, and went on to serve under four leaders of the opposition (Matt Birney, Paul Omodei, Troy Buswell, and Colin Barnett). He was elected deputy leader of the Liberal Party in January 2008, when Buswell became leader, and retained the deputy leadership when Buswell was replaced by Barnett later in the year. The Liberal Party formed government after the 2008 state election, with Hames becoming Deputy Premier, Minister for Health, and Minister for Indigenous Affairs (for a second time) in the new ministry. In December 2010, he was also appointed Minister for Tourism. However, Hames resigned as tourism minister in July 2013, after being accused of abusing an accommodation entitlement. Later in the year, in December 2013, he replaced Terry Redman as Minister for Training and Workforce Development. He eventually reclaimed his previous tourism portfolio in a December 2014 reshuffle, with Liza Harvey taking on the training portfolio.
 Passage 3:Storm Thorgerson, who had done the majority of album covers for Pink Floyd, did the Echoes art which features recursive windows in an infinite regression as a nod to his own cover for 1969's Ummagumma, and the objects on each landscape refer to the Pink Floyd discography. For instance, there's the man on fire from Wish You Were Here, another wearing the Delicate Sound of Thunder lightbulb suit, dolls of the Atom Heart Mother cow and the Animals pig, a bike and both a brick wall and the hammers from The Wall. Eventually Thorgerson opted to make two images, with another used for the back cover. To create the idea on a photograph, various walls - which had varied measurements and angles to ensure that "nothing seemed to fit other than by eye through the lens." - were built and put in a country landscape in Sussex. Actors, props and fittings were set in and between those walls. The original design was one of two sketches submitted for Dream Theater's 1997 album Falling into Infinity, with the original being framed and hanging in the home of former Dream Theater drummer Mike Portnoy and is pointed out by Portnoy in his Hudson Music instructional drum DVD In Constant Motion.
