Example Input: Question: Which town was near the camp that, until May 1942, the Germans used it to mostly kill off Jews from Belgrade and other parts of Serbia? Passage 1:William Alfred Passavant was born in 1821 in Zelienople, Pennsylvania, the third and youngest son of Phillipe Louis Passavant and Fredericka Wilhelmina Basse (nicknamed "Zelie," hence the town's name). His grandfather, Baron Dettmar Basse, born in Iserlohn in the Ruhr Valley in what was then the Grand Duchy of Hesse and later became Germany, spent a decade in Paris as a diplomat and merchant before fleeing the Napoleonic Wars and emigrating to Philadelphia and then Pittsburgh in 1801. Drawn by the prospect of religious freedom and economic opportunity, the widower Baron bought 10,000 acres along Connoquenessing Creek in Butler County, Pennsylvania, began building a wood framed castle, and founded (with Christian Buhl) a new town complete with sawmill, brickyard, and an iron furnace. He also traveled and sent glowing letters back to Germany, persuading his daughter and her new husband (a French Huguenot who fled after repeal of the Edict of Nantes) to emigrate in 1807 from Frankfurt.
 Passage 2:The 1st King's Dragoon Guards was a cavalry regiment in the British Army. The regiment was raised by Sir John Lanier in 1685 as the 2nd Queen's Regiment of Horse, named in honour of Queen Mary, consort of King James II. It was renamed the 2nd King's Own Regiment of Horse in 1714 in honour of George I. The regiment attained the title 1st King's Dragoon Guards in 1751. The regiment served as horse cavalry until 1937 when it was mechanised with light tanks. The regiment became part of the Royal Armoured Corps in 1939. After service in the First World War and the Second World War, the regiment amalgamated with the 2nd Dragoon Guards (Queen's Bays) in 1959 to form the 1st The Queen's Dragoon Guards.
 Passage 3:After the April war of 1941 when Germany and its allies occupied and partitioned the Kingdom of Yugoslavia, entire Syrmia region (including the left bank of the Sava) became part of the Independent State of Croatia where they set the Ustaše regime. Nazi secret police, Gestapo, took over Sajmište. They encircled it with several rings of barbed wire turning it into what they referred to as "collection center" – a euphemism for a prison. It eventually became a concentration camp. Until May 1942 Germans used Sajmište concentration camp to mostly kill off Jews from Belgrade and other parts of Serbia. From April 1942 onwards, Serbian prisoners were transported in from Jasenovac and Stara Gradiška concentration camps run by ISC Croatian Ustaše. Partisans captured throughout Serbia were also sent to Sajmište. Detainees were also sent in from other parts of Yugoslavia, especially Serbs after major German offensives on briefly liberated territories. Executions of captured prisoners lasted as long as the camp existed. During their heavy “Easter bombing” of Belgrade, Allied aircraft bombed Sajmište on 17 April 1944, killing some 100 inmates and inflicting heavy damage on the camp itself, destroying all the buildings except for the Spasić pavilion and the Central tower..

Example Input: Question: What country was Hope sent to after Erskine's death? Passage 1:The East Lost Angeles freeway system and the East Los Angeles Interchange serve as an important center for the Los Angeles freeway network. It is also known for being the cause of displacing countless Mexican Angeleno communities, as 19 percent of East Los Angeles is intertwined with freeways. The freeway system grew as multiple freeways were built over two decades: the Santa Ana (5) Freeway (1944), the Hollywood (101) Freeway (1948), the San Bernardino (10) Freeway (1953), the Santa Monica (10) Freeway (extended to the East Los Angeles Interchange in 1961), the Long Beach (710) Freeway (1961), and the Pomona (60) Freeway (1965).Boyle Heights and neighboring communities protested against the first construction phases of the freeways. Community leaders rallied together to fight for their neighborhoods as they circulated petitions and organized public hearings. The construction of the freeways started as scheduled despite the resistance. The numerous freeways in this era displaced many East Los Angeles residents as they had their homes and property seized. Schools, churches, and community parks were also lost from construction. One notable structure lost in Boyle Heights was Saint Isabella Church and the Catholic elementary school. The loss of Hollenbeck Park was also a devastation to the community, since there was already a shortage of parks in the area. The Divide of Highways again justified the loss of communities by contending that residents would save time using the new freeways. Boyle Heights was a densely populated area because of low mortgages that were enjoyed by Mexican Angelo families. When families were forced to give up their homes they struggled to find homes that matched in affordability. Some families were also displaced in gang ridden areas and further from the freeways that they never used. The remaining residents in the area also still suffer the consequences of the construction of the surrounding freeways. Residents are now separated from parts of the community and face many effects of the area's air pollution caused by vehicles.
 Passage 2:Hope joined the Scots Brigade as a cadet in 1778. The Brigade, in the service of the Dutch Republic, was then stationed at Bergen op Zoom and later moved to Maastricht. He had reached the rank of Captain when like other officers he left the Dutch service in 1782 during the Fourth Anglo-Dutch War and was on half-pay until 29 September 1787, when he joined the 60th Foot (Royal American Regiment), but the regiment was reduced and he was briefly on half-pay again before joining the 13th Light Dragoons on 30 June 1788. In February 1793, shortly after the French Revolutionary War had begun, Hope served as aide-de-camp to Sir William Erskine in the Flanders Campaign. On 25 March 1795, a few days after Erskine's death, Hope was promoted to major in the 28th Light Dragoons, becoming lieutenant-colonel of that regiment on 20 February 1796. Sent to the Cape Colony, the 28th, under Hope's command, helped to rebuff a Dutch attempt in August, to reclaim the colony.
 Passage 3:Emmanuel was born on 2 March 1989 in Southend-on-Sea, a seaside resort town in Essex, England. Emmanuel is the second child of a half Dominican (Dominiquais) and half English mother, and a father of half-Saint Lucian and half English descent. Emmanuel demonstrated an affinity for the arts at an early age; she recalled that her mother first took notice of her passion and desire to become an actress during Emmanuel's attendance at the independent St Hilda's School (now closed) and later grammar Westcliff High School for Girls. In an interview with the New York Daily News, she commented, "When I was 3, [I'd] always cause drama that my mum decided maybe I should channel it properly—so she started me on acting, singing and dancing classes". At the age of 10, she played Young Nala in the West End production of the musical The Lion King.

Bieber said, "It's really awesome to be able to work with professional dancers, you know, people that were in, like, ABDC, and also got an approval from choreographer Jamaica, who said Bieber was "killing it" and that she didn't have to give him any corrections. It made its premiere during the June 17, 2010 results show of the seventh season of So You Think You Can Dance, and was introduced by Usher after his performance of "OMG".

Singer/actress and model Katerina Graham makes a cameo in a scene with Poreotics. Bieber's best friend Ryan Butler, who appeared in the "One Time" video, also appears alongside Bieber, wearing a T-shirt advertising his Twitter account.

A backpack choreography scene with LXD recalls Usher's 1997 video for "You Make Me Wanna".
