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: How long had the United Nations been in existence when Gross was appointed? Passage 1:On October 11, 1949, United States Secretary of State Dean Acheson appointed Gross as the United States' deputy delegate to the United Nations. Only two months later, the chief delegate, Warren Austin, took a leave of absence, and Gross took over as acting head of the U.S. delegation to the U.N. The major issue facing the United Nations at that time was the Soviet Union's proposal that, with the conclusion of the Chinese Civil War, the Communist People's Republic of China should replace the Republic of China on the United Nations Security Council. On January 13, 1950, the Soviet delegate, Jacov Malik, walked out of the Security Council in protest. Malik remained absent for several months, and as such the Soviet Union failed to exercise its veto power to block United Nations Security Council Resolution 82, which condemned North Korea at the beginning of the Korean War; on behalf of the U.S., Gross voted in favor of the resolution. In fall 1950, Warren Austin returned from his leave of absence, and Gross continued to serve as Austin's deputy until 1953.
 Passage 2:In 1908, she met John Dailey de Angeli, a violinist, known as Dai. They were married in Toronto on April 12,1910. The first of their six children, John Shadrach de Angeli, was born one year later. After living in many locations in the American and Canadian West, they settled in the Philadelphia suburb of Collingswood, New Jersey. There in 1921 Marguerite started to study drawing under her mentor, Maurice Bower. In 1922, Marguerite began illustrating a Sunday School paper and was soon doing illustrations for magazines such as The Country Gentleman, Ladies' Home Journal, and The American Girl, besides illustrating books for authors including Helen Ferris, Elsie Singmaster, Cornelia Meigs, and Dorothy Canfield Fisher. Her last child, Maurice Bower de Angeli, was born in 1928, seven years before the 1935 publication of her first book, Ted and Nina Go to the Grocery Store. The de Angeli family moved frequently, returning to Pennsylvania and living north of Philadelphia in Jenkintown, west of Philadelphia in the Manoa neighborhood of Havertown, on Carpenter Lane in Germantown, Philadelphia, on Panama Street in Center City, Philadelphia, in an apartment near the Philadelphia Art Museum, and in a cottage in Green Lane, Pennsylvania. They also maintained a summer cabin on Money Island in Toms River, New Jersey. Marguerite's husband died in 1969, eight months before their 60th wedding anniversary.
 Passage 3:The Tremp Basin evolved into a sedimentary depression with the break-up of Pangea and the spreading of the North American and Eurasian Plates in the Early Jurassic. Rifting between Africa and Europe in the Early Cretaceous created the isolated Iberian microplate, where the Tremp Basin was located in the northeastern corner in a back-arc basin tectonic regime. Between the middle Albian and early Cenomanian, a series of pull-apart basins developed, producing a local unconformity in the Tremp Basin. A first phase of tectonic compression commenced in the Cenomanian, lasting until the late Santonian, around 85 Ma, when Iberia started to rotate counterclockwise towards Europe, producing a series of piggyback basins in the southern Pre-Pyrenees. A more tectonically quiet posterior phase provided the Tremp Basin with a shallowing-upward sequence of marine carbonates until the moment of deposition of the Tremp Formation, in the lower section still marginally marine, but becoming more continental and lagoonal towards the top.

Example Input: Question: Who is the CEO of the company that released the 2018 film featuring Jenna Fischer? Passage 1:Samuel James "Sam" Ervin Jr. (September 27, 1896April 23, 1985) was an American politician. A Democrat, he served as a U.S. Senator from North Carolina from 1954 to 1974. A native of Morganton, he liked to call himself a "country lawyer," and often told humorous stories in his Southern drawl. During his Senate career, Ervin was a legal defender of the Jim Crow laws and racial segregation, as the South's constitutional expert during the congressional debates on civil rights. Unexpectedly, he became a liberal hero for his support of civil liberties. He is remembered for his work in the investigation committees that brought down Senator Joseph McCarthy in 1954 and especially for his investigation of the Watergate scandal in 1972 that led to the resignation of Richard Nixon.
 Passage 2:Gorham's Rangers was one of the most famous and effective ranger units raised in the colonial North America. Formed by John Gorham, the unit served as the prototype for many subsequent ranger forces, including the better known Rogers' Rangers. The unit started out as a Massachusetts provincial auxiliary company, which means it was not part of the province's normal militia system. Recruited in the summer of 1744 at the start of King George's War, Governor William Shirley ordered the unit raised as reinforcements for the then-besieged British garrison at Fort Anne in Annapolis Royal. Over the next eight years the unit proved remarkably effective at suppressing Acadian and Mi'kmaq resistance to British rule in Nova Scotia and helped to both expand and secure the British sphere of influence in the region. Initially a sixty-man all-Indian company led by British colonial officers, the original Native American members of the unit were gradually replaced by Anglo-Americans and recent Scots and Irish immigrants and were a minority in the unit by the mid-1750s. The company were reconnaissance experts as well as renowned for their expertise at both water-borne operations and frontier guerrilla warfare. They were known for surprise amphibious raids on Acadian and Mi'kmaq coastal or riverine settlements, using large whaleboats, which carried between ten and fifteen rangers each. This small unit was the main British military force defending Nova Scotia from 1744 to 1749. The company became part of the British army and was expanded during the Seven Years' War and went on to play an important role in fighting in Nova Scotia as well as participating in many of the important campaigns of the war, particularly distinguishing itself at the Siege of Quebec in 1759.
 Passage 3:Anthony Sadler Jr. (born July 13, 1992) is an American-French television personality. Sadler, along with Alek Skarlatos and Spencer Stone, stopped a gunman on a Paris-bound train travelling from Amsterdam via Brussels in August 2015, gaining international recognition for their role in the event. Recognized by then-U.S. President Barack Obama and French President François Hollande, Sadler received several awards and decorations for his actions. He, along with his friends, was awarded the Legion of Honour by the French president which is the highest French order for military and civil merits. After the event, Sadler made several television appearances, including a guest appearance on The Tonight Show Starring Jimmy Fallon and honored with the on Spike TV, among other appearances. He, Skarlatos and Stone co-authored a memoir, titled The 15:17 to Paris, published in August 2016, which detailed the events leading up to the attack, which occurred a year prior to the release of the book. Clint Eastwood directed a biographical based on Sadler, Skarlatos and Stone's memoir, starring them, along with actresses Jenna Fischer and Judy Greer. The film was released in early 2018 by Warner Bros. Pictures. Sadler graduated from California State University, Sacramento in 2017.
