Input: Consider Input: Question: What year did the Scramble for Africa begin? Passage 1:In 945, Bosenbach had its first documentary mention when Otto I, Holy Roman Emperor, granted his faithful follower Franko a few landholds. To better describe where these landholds lay, both Reichenbach and Bosenbach were named. Either Franko or his heirs yielded these lands shortly after 945 to Saint Maximin's Abbey in Trier. Until about 1100, Bosenbach was listed time and again as being among the monastery's holdings. Territorially, Bosenbach belonged to the Imperial Domain (Reichsland) around Kaiserslautern and about 1130, it came to be held as a Palatine fief by the Counts of Veldenz. About 1282, the Amt of Bosenbach (Bosenbach, Niederstaufenbach and Friedelhausen) was held in common ownership by the Counts of Veldenz and the Waldgraves. Later, in the 14th and 15th centuries, the common ownership had ended and it was owned by the Waldgraves and Rhinegraves (one group). In 1595, through territorial trade, the Amt found its way back into the Duchy of Palatinate-Zweibrucken. From the years 1514, 1537 and 1578 come three Weistumer dealing with Bosenbach (a Weistum cognate with English wisdom was a legal pronouncement issued by men learned in law in the Middle Ages and early modern times; Weistumer is the plural).
Passage 2:The 1880s saw an intense competition between the European powers for territories in Africa, a process known as the Scramble for Africa. The process culminated in the Berlin Conference of 1884, in which the European nations concerned agreed upon their respective territorial claims and the rules of engagements going forward. As a result of this France gained control of the upper valley of the Niger River (roughly equivalent to the areas of modern Mali and Niger). France had already conquered most of northern Algeria during the period 1830-47, incorporating it as an integral part of France. France occupied the area of modern Niger in 1900, declaring it a military territory, ruled originally from Zinder. Niger was originally included, along with modern Mali and Burkina Faso, within the Upper Senegal and Niger colony, however it was split off in 1911 and became a constituent of the federal colony of French West Africa (Afrique occidentale francaise, abbreviated AOF). In the meantime in Algeria France had been pushing south from the littoral region, conquering much of the Algerian Sahara in 1902. A boundary between French West Africa and French Algeria (i.e. what are now Algeria's borders with Mauritania, Mali and Niger) was agreed on 7 June 1905 by the Commandant of Upper Senegal and Niger and the Military Commander of the Department de l'Oasis within French Algeria. The border was further defined by the Niamey Convention of June 1909.
Passage 3:The discography of South Korean-born Australian recording artist Dami Im consists of five studio albums, two extended plays, ten singles, two album appearances, and four music videos. Im began her music career as a gospel singer in Korea and independently released her debut studio album, Dream, in 2010. She was the winner on the fifth season of The X Factor Australia in 2013, and subsequently received a contract with Sony Music Australia. Im released her self-titled second studio album in November 2013, which features selected songs she performed as part of the top twelve on The X Factor. The album debuted at number one on the ARIA Albums Chart and was certified platinum by the Australian Recording Industry Association (ARIA), denoting shipments of 70,000 copies. Additionally, the album also included Im's debut single "Alive", which topped the ARIA Singles Chart and was certified platinum. She became the first X Factor Australia contestant to follow up a number one single with a number one album on the ARIA Charts.

Input: Consider Input: Question: Who wrote the first song that Graham Clark learned to sing? Passage 1:Graham Clarke was born in Holy Name Medical Center in Teaneck, New Jersey on July 11, 1970. Clarke's parents, Lorain Maria Clarke (nee Meola), a homemaker, and Thomas Michael "Moose" Clarke, a stockbroker were married in 1960 and had three children before Graham: Thomas in 1961, Dennis in 1962, and Martin in 1965. He spent the first seven years of his life in a split-level home in Dumont, New Jersey. He was frequently in the room when his older brother Tommy would have guitar lessons with musician Bob Berger. Bob noted one time when a screaming Graham had scarlet fever "That boy's screaming on key! That's a C note." Such exposure to music had an obvious influence on him and there is an oft-told family story that claims the first song Graham ever learned to sing was "Me and Julio Down by the Schoolyard," a popular song Tommy was learning on the guitar at the time. At the age of seven, his family moved one town over to Oradell, where he attended St. Joseph Grammar School, and later Bergen Catholic High School. Neither school had a music program so Graham taught himself how to play the guitar using his brother's old fake books.
Passage 2:Adkin made his debut for Sussex in a List A match against the touring Bangladeshis at the County Ground, Hove, in 2010. Batting at number eight, Adkin contributed 30 runs to Sussex's total of 253 all out, before he was dismissed by Mashrafe Mortaza. He took the wicket of Jahurul Islam in the Bangladeshis innings, with Sussex dismissing them for 104 to win the match by 149 runs. Later in that season he made his first-class debut against Surrey at Woodbridge Road, Guildford, in the County Championship. He scored 45 in the match and took figures of 138 with the ball. With the need to concentrate on his university studies, Adkin made just four first-class appearances in the 2011 season, playing in against Oxford MCCU in May, as well as making three appearances in the County Championship later in the season. Adkin also made two List A appearances in that seasons Clydesdale Bank 40, against Derbyshire and the Netherlands.
Passage 3:The Saint Peter's Square and the Piazza Navona sets were built on the same backlot; after completion of scenes at the former, six weeks were spent converting the set, knocking down the Basilica side and excavating of tarmac to build the fountain. As there had been filming at the real Piazza Navona, the transition between it and the replica had to be seamless. To present the Santa Maria del Popolo undergoing renovation, a police station in Rome opposite the real church was used for the exterior; the scaffolding would hide that it was not the church. Cameron built the interior of Santa Maria del Popolo on the same set as the recreated Santa Maria della Vittoria to save money; the scaffolding also disguised this. The film's version of Santa Maria della Vittoria was larger than the real one, so it would accommodate the cranes used to film the scene. To film the Pantheon's interior, two aediculae and the tomb of Raphael were rebuilt to scale at a height of , while the rest was greenscreen. Because of the building's symmetrical layout, the filmmakers were able to shoot the whole scene over two days and redress the real side to pretend it was another. The second unit took photographs of the Large Hadron Collider and pasted these in scenes set at CERN.

Input: Consider Input: Question: When was the flag that the King pulled first created? Passage 1:Before the ceremony began, King Edward VIII, present in his capacity as king of Canada, inspected the guard of honour, was introduced to the honoured guests, and spent approximately half an hour speaking with veterans in the crowd. Two Royal Air Force and two French Air Force squadrons flew over the monument and dipped their wings in salute. The ceremony itself began with prayers from chaplains representing the Church of England, the United Church of Canada, and the Roman Catholic Church. Ernest Lapointe, Canadian Minister of Justice, spoke first, followed by Edward VIII who, in both French and English, thanked France for its generosity and assured those assembled that Canada would never forget its war missing and dead. The King then pulled the Royal Union Flag from the central figure of Canada Bereft and the military band played the Last Post. The ceremony was one of the King's few official duties before he abdicated the throne. The pilgrimage continued, and most participants toured Ypres before being taken to London to be hosted by the British Legion. One-third of the pilgrims left from London for Canada on 1 August, while the majority returned to France as guests of the government for another week of touring before going home.
Passage 2:McClean made his first start for Sunderland in their 10 victory over Manchester City on 1 January 2012, and scored his first senior goal for the Black Cats in a 41 win against Wigan Athletic two days later; on 8 January, he scored and assisted Sebastian Larsson in a 20 win at Peterborough United in the third round of the FA Cup. McClean provided the assist for Stephane Sessegnon's opening goal in Sunderland's 20 victory over Swansea City on 21 January, and got another assist in the equalising goal for Fraizer Campbell in the next round of the cup against Middlesbrough on 29 January. Ahead of the replay for that fixture, Middlesbrough manager Tony Mowbray used McClean as an example for young players to follow. McClean turned provider again in Sunderland's 30 victory over Norwich City, assisting Sessegnon's goal, then scored the only goal in a win over Stoke City on 4 February in snowy conditions at the Britannia Stadium. A week later, he opened the scoring in Sunderland's 21 home loss to Arsenal after Per Mertesacker injured himself. On 23 March, Sunderland announced that McClean had signed a new contract intended to force him to stay at the club until the summer of 2015. A day later, he helped them to a 31 victory over relegation-threatened Queens Park Rangers by assisting the opening goal for Nicklas Bendtner and later scoring by himself. McClean won Sunderland's Young Player of the Year Award, at the end of the 201112 season.
Passage 3:After stopping at Madeira and the Cape Colony, the Investigator reached Australia in December 1801. It sailed along the south coast, through Bass Strait, and north along the east coast to overwinter at Port Jackson. It then sailed north up the east coast, rounding the Cape York Peninsula and entering the Gulf of Carpentaria. The ship by then being in extremely poor condition, the survey was broken off and the Investigator was sailed to Koepang, Timor. Many members of the crew became sick with dysentery there, and Flinders took the decision to return to Port Jackson as quickly as possible. They sailed southwards well west of the west coast of Australia, then east along the south coast, arriving back at Port Jackson in June 1802. The Investigator was condemned, and Flinders sailed for England as passenger on the Porpoise, there to ask for a new ship. Though initially inclined to remain at Port Jackson with some of the other naturalists, ultimately Allen chose to board the Porpoise. On 17 August the Porpoise was wrecked on Wreck Reef. Everyone on board was marooned on a sandbank for six weeks while Flinders sailed the ship's cutter back to Port Jackson to seek help. When help arrived it was in the form of two ships, one of which would return to Port Jackson, while the other was en route to China. Allen elected to sail to China. From there he took a passage to England on the Henry Addington. Arriving at Brighton on 8 August 1804, Allen made his way to London, where he gave to Banks the first eye-witness account of the voyage, including breaking the news of the death at Port Jackson of the gardener Peter Good.
