Example Input: Question: How long had Ronald Reagan been President of the United States when the Falklands war began? Passage 1:The Union for Democratic Renewal (Union pour la Renouveau Démocratique) was a coalition of political parties in the Republic of the Congo. The coalition was led by Bernard Kolélas, who was also the leader of the coalition's largest party, the Congolese Movement for Democracy and Integral Development (MCDDI). The URD parties supported the transitional government of Prime Minister André Milongo (1991–1992) and opposed the National Alliance for Democracy (AND), which included the Pan-African Union for Social Democracy (UPADS) and the Congolese Labour Party (PCT). In the parliamentary election held in June–July 1992, the AND parties won a slight majority of seats in the National Assembly and UPADS leader Pascal Lissouba was victorious over Kolélas in the August 1992 presidential election.
 Passage 2:He graduated from the University of Damascus in 1923 with a degree in law, and joined the city government in 1925. At this time he also actively ran his family's estates throughout the country. In the 1930s, he became close associates with leading members of the anti-French National Bloc coalition such as future presidents Hashim al-Atassi and Shukri al-Kuwatli. He remained a longtime supporter of the former, but often quarreled with the latter, whom he accused of being too authoritarian. In 1941 the French appointed him Prime Minister and Acting President, having had no success in finding a viable candidate since the resignation of the nationalist Atassi in 1939. However he was replaced 5 months later with a French loyalist, Taj al-Din al-Hasani. Azm served repeatedly in parliament and in the cabinet from 1943 to 1947. He became a focus of opposition when he resigned from the cabinet in 1945 and lead the forces opposed to Kuwatli's drive to amend the constitution to allow himself a second term in office. Kuwatli prevailed, and Azm ran against him in 1947 and lost. However he accepted the position of envoy to France and served in that capacity for a year. He concluded successful arms purchases from France and later from the Soviet Union. In May 1948, Azm agreed to form a multi-party cabinet under Kuwatli which served until March 1949. He allied himself with France and the United States and attempted to obtain loans from them for domestic development. He traveled frequently to attend United Nations assemblies on the Palestinian problem. Azm clashed with members of the military, especially Chief of Staff Husni al-Za'im. The latter launched a coup d'état on 29 March 1949 and imprisoned both Azm and president Kuwatli. When Za'im was overthrown five months later, Azm returned to parliament as deputy for Damascus and became minister of finance. He was also elected into the Constituent Assembly that drafted a new constitution for Syria. He became Prime Minister again under Hashim al-Atassi's second administration, in June 1950, heading three cabinets between then and 1951. Azm closed the border to Lebanese goods in an attempt to prevent the crash of domestic Syrian industry due to rampant Lebanese imports. He also clashed repeatedly with the military because he refused to appoint officers in any of his cabinets, and always reserved the defense portfolio for himself. He also clashed with pro-Hashemite elements in Syrian politics that advocated union with Iraq. Socialists distrusted him because of his aristocratic and wealthy Ottoman background. Azm left the public arena from 1951 to 1954 in protest over the coup of Adib al-Shishakli which toppled Atassi's democratic administration.
 Passage 3:On December 1, 1981, United States President Ronald Reagan signed a presidential finding which authorized covert operations in Nicaragua. This plan initially called for the U.S. government to cooperate with the Argentinian government, which was already engaged in a similar operation, to train and fund an existing terrorist group in Nicaragua known as the Contras. The Contras also contributed to drug dealing in the US and brought a lot of crack cocaine. A reporter for the San Jose Mercury News proved the connection between the crack epidemic and the Contras. Initially the Contras were a group of republican guard members from the old Somoza regime ousted by the Sandinistas after the revolutionary conflict. Later, through the recruitment efforts of the CIA, the group became supplemented by mercenary guerrillas and was extensively trained by the CIA. Eventually, due to the U.S. alliance with Great Britain during the Falklands war, Argentina withdrew support for these programs and the CIA had to relocate their training sites to Honduras.

Example Input: Question: Who were the Three Witnesses to the Book of Mormon? Passage 1:Born near Mehoopany, Wyoming County, Pennsylvania, Harris was the son of Emer Harris and Deborah Lott. He was a nephew of Martin Harris, one of the Three Witnesses to the Book of Mormon, and a descendant of Thomas Harris, companion in exile of Roger Williams, and one of the founders of Providence, Rhode Island. Harris was baptized a member of Church of Jesus Christ of Latter Day Saints in September 1842, by Milton Stow, near Nauvoo, Illinois. Harris served as a guard in Nauvoo to protect Joseph Smith against mob violence. He also served in the Nauvoo Legion and witnessed the laying of the cornerstone of the Nauvoo Temple. After being driven with other Latter-day Saints from Nauvoo in 1846, he resided temporarily in St. Louis, Missouri until 1850, when he went to Kanesville, Iowa and then to Utah.
 Passage 2:After the war he spent another eight years organising tourist services between Iraq, Persia (now Iran) and Syria for the Mesopotamian Trading Agency of Ashar, Basrah. His wife may have joined him in 1924. He returned to South Australia in 1926 with the intention of setting up a regular service between Adelaide and Darwin via Oodnadatta and Alice Springs. He conducted a demonstration run with eight men and four women in three Studebaker cars and a Thornycroft truck, leaving Adelaide on 18 May and arrived in Darwin on 3 June; left there on 7 June and returned to Adelaide on 25 June, travelling via Camooweal, Queensland and Marree, South Australia, publicised by Duncan and Fraser (agents for both Thornycroft and Studebaker) and as they were equipped with a short-wave transceiver, gave nightly reports on radio 5CL. Despite a second successful round trip that year, Bagot abandoned his idea of regular service when the Commonwealth Government turned down his application for a subsidy. He found employment with General Motors and in 1930 "Captain Bagot" as he was called by admirers (or "'Alphabetical Bagot' as he was known to the many who disliked him), founded the Citizens' League of South Australia, which opposed Unionism, Communism and the White Australia Policy as benefiting the working classes, yet also opposing Fascism. This was the time of the Great Depression and he also supported the Young People's Employment Council and the Rev. Samuel Forsyth's (1881–1960) Forsyth Industrial Colony "Kuitpo Colony" near Kuitpo Forest, which was training boys as farm workers. The Citizen's League attempted political influence by promising support to political candidates, and was a factor in the election of the Independent candidate George Connor to the Assembly seat of Alexandra in 1934.
 Passage 3:John Francis Barnett was the son of John Barnett's brother, Joseph Alfred, also a professor of music. John Francis carried on the traditions of the family as a composer and teacher. He obtained a queen's scholarship at the Royal Academy of Music, studied under William Sterndale Bennett and developed into an accomplished pianist, visiting Germany to study in 1857 and playing Mendelssohn's Piano Concerto No. 2 in D minor at a Gewandhaus concert at Leipzig in 1860. His teachers at the Conservatoire in Leipzig included the great pianist Ignaz Moscheles, who had been a pupil of Beethoven. Back in Britain, Barnett enjoyed a successful career as a pianist for some years but concentrated increasingly on composition and teaching. He became noticed as a composer with his symphony in A minor (1864), and followed this with a number of compositions for orchestra, strings and piano. His cantata The Ancient Mariner premiered at Birmingham in 1867, and another, Paradise and the Peri, in 1870, both successfully. In 1873 his most important work, the oratorio The Raising of Lazarus, was written, and in 1876 produced at Hereford. During this period, Barnett also composed several other minor cantatas and piano pieces, and he took an active part as a professor at the Guildhall School of Music and one of the founder-professors of the Royal College of Music, where his students included Marmaduke Barton.
