Q: 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 (née 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 1–38 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.

Q: 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.

Q: Question: How long after the Battle of Princeton did the war during which Fort Mercer was built end? Passage 1:The Calgary Flames selected him in the eighth round, 182nd overall at the 1981 NHL Entry Draft, and he began his professional career in 1983–84 with a 30-point season for the Colorado Flames of the Central Hockey League (CHL). He then spent the majority of three seasons in the American Hockey League (AHL) with the Moncton Golden Flames. He was named to the AHL second All-Star Team in 1984–85, and served as captain of the Golden Flames in 1985–86. DeGray appeared in one NHL game that season, making his NHL debut with Calgary on March 6, 1986, against the New York Rangers.

 Passage 2:Mušicki was stationed in Slavonski Brod at the time of the Axis invasion of Yugoslavia in April 1941 and served as the Royal Yugoslav Army commander responsible for the railroad between Belgrade and Zagreb in the rank of colonel. He demonstrated his support for the Germans by helping their forces during the invasion. Yugoslavia was quickly conquered by the Axis powers and Mušicki remained in Slavonski Brod for several months after the conquest. He attempted to join the Ustaše Militia there, but was rejected. He went to Belgrade in mid-August, where he was received by Zbor leader Dimitrije Ljotić. On 6 October, Milan Nedić, the Prime Minister of the Axis-installed puppet Government of National Salvation, appointed Mušicki to lead the Serbian Volunteer Command (, SDK). Mušicki was involved in executing Serb civilians in the town of Čačak in December 1941. He and Milan Aćimović contacted Chetnik leader Draža Mihailović on 5 December, possibly in an effort to warn him in advance of the assault the Germans had planned, codenamed Operation Mihailovic. This action prompted the Germans to question Mušicki's loyalty. He was removed from command at the end of 1941 and imprisoned by the Germans, but was later freed at Nedić's intervention.
 Passage 3:Fort Mercer was a fort on the Delaware River in New Jersey constructed by the Continental Army during the American Revolutionary War. Built by Polish engineer Thaddeus Kosciuszko under the command of George Washington, Fort Mercer was built in 1777 to block the approach to Philadelphia, Pennsylvania in concert with Fort Mifflin on the Pennsylvania side. Fort Mercer was located in an area called Red Bank, in what is now the borough of National Park, Gloucester County, New Jersey. The fort was named in honor of Brigadier General Hugh Mercer who had died earlier that year at the Battle of Princeton. The fort's site is now part of Red Bank Battlefield Historical Park, which includes a monument and museum. Several cannons attributed to British warships lost supporting the attack on the fort, and others found buried at the fort itself, are in the park.
