 Passage 2:In August 1915, after recovering from his injuries, Elles was one of three officers specially selected by General Sir William Robertson, soon to be Chief of the Imperial General Staff (CIGS), the professional head of the British Army, to liaise with troops at the front and pass the information directly to the British General Headquarters (GHQ). In January 1916, as a General Staff Officer (GSO), Elles was sent by General Sir Douglas Haig, the Commander-in-Chief (C-in-C) of the BEF on the Western Front, to investigate the first tanks or "caterpillars" being built in England. He attended the first trials of "Mother" and reported back to Haig on its success. During the summer of 1916, he was tasked to report back from the Somme, where the tanks were first used. Elles was appointed to head the Heavy Branch (the first tank units) of the Machine Gun Corps in France on 29 September 1916, with the temporary rank of colonel.

 Passage 2:The film begins with a narrated map showing the Confederate Army of Northern Virginia, commanded by Robert E. Lee, crossing the Potomac River to invade the North in June 1863, marching across Maryland and into Pennsylvania. On June 30, Confederate spy Henry Thomas Harrison reports to Lt. Gen. James Longstreet, commander of the First Corps, that the Union Army of the Potomac is moving in their direction, and that Union commander Joseph Hooker has been replaced by George Meade. Longstreet reports the information to General Lee, who is concerned that the army is moving "on the word of an actor", as opposed to that of his cavalry chief, J. E. B. Stuart. Nonetheless, Lee orders the army to concentrate near the town of Gettysburg. At the Union encampments near Union Mills, Maryland, Col. Joshua Lawrence Chamberlain of the 20th Maine is ordered to take in 120 men from the disbanded 2nd Maine who had resigned in protest, with permission to shoot any man who refuses to fight. Chamberlain speaks to the men, and is able to persuade all but six to take up arms.

Example Input: 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.
