[EX Q]: Question: Who was chairman before Rawlings took over in 1981? Passage 1:Thomas was born to Thomas Marston Green Sr., a future Colonel in the Continental Army, and Martha Wills. He was born in Williamsburg, Virginia, on February 26, 1758. In 1782 he moved with his family to Natchez District, Mississippi Territory. He would later move to Fayette, Mississippi where he would build the Springfield Plantation, and where he would live until his death. The Green family were good friends with Andrew Jackson and Rachel Donelson. Thomas's brother Abraham married Elizabeth Caffery who was the niece of Rachel Jackson. In August 1791, Andrew Jackson and Rachel were married at the Green Family Springfield Plantation. The marriage ceremony was performed by Thomas Green Sr., while Thomas Jr. served as a witness. Andrew and Rachel would later find out that Rachel's divorce was not finalized, at the time of the wedding.
 Passage 2:New York played a pivotal role during the American Revolution and subsequent war. The Stamp Act Congress in 1765 brought together representatives from across the Thirteen Colonies to form a unified response to British policies. The Sons of Liberty were active in New York City to challenge British authority. After a major loss at the Battle of Long Island, the Continental Army suffered a series of additional defeats that forced a retreat from the New York City area, leaving the strategic port and harbor to the British army and navy as their North American base of operations for the rest of the war. The Battle of Saratoga was the turning point of the war in favor of the Americans, convincing France to formally ally with them. New York's constitution was adopted in 1777, and strongly influenced the United States Constitution. New York City was the national capital at various times between 1785 and 1790, where the Bill of Rights was drafted. Albany became the permanent state capital in 1797. In 1787, New York became the eleventh state to ratify the United States Constitution.
 Passage 3:Rawlings initially came to power in Ghana as a flight lieutenant of the Ghana Air Force following a coup d'état in 1979 and, after initially handing power over to a civilian government, took back control of the country on 31 December 1981 as the Chairman of the Provisional National Defence Council. In 1992, Rawlings resigned from the military, founded the National Democratic Congress, and became the first President of the Fourth Republic. He was re-elected in 1996 for four more years. After two terms in office, the limit according to the Ghanaian Constitution, Rawlings endorsed his vice-president John Atta Mills as presidential candidate in 2000. He currently serves as the African Union envoy to Somalia.

[EX Q]: Question: Who starred in the film considered to be one of the earliest slasher films? Passage 1:Chillag emigrated to Australia after the war, having found no surviving family back in Hungary and being unable to remake the family business following the arrival of communism. Marrying a British-born expatriate in 1950, he worked for the Australian Atomic Energy Commission between 1957 and 1963, living in Sydney. He moved to Leeds, England in 1962, to work in Boston Spa until retirement, whereupon he became a European Information Officer for Leeds Metropolitan University. His daughter, diagnosed with Down syndrome, prompted him to work voluntarily with Mencap, and he continued to give lectures on his experiences at the Imperial War Museum. In 2004, he published his memoirs, The Odyssey of John Chillag, a Hungarian Jew Born in Vienna 2006: From Győr in Hungary to Australia and England Via Auschwitz and Buchenwald.
 Passage 2:His work has proved very influential. Bava directed what is now regarded as the earliest of the Italian giallo films, The Girl Who Knew Too Much (1963) and Blood and Black Lace (1964). His 1965 sci-fi/ horror film Planet of the Vampires was a thematic precursor to Alien (1979). Although comic books had served as the basis for countless serials and children's films in Hollywood, Bava's  (1968) brought an adult perspective to the genre with its' Pop art influence of Andy Warhol and Roy Lichenstein. Many elements of his 1966 film Kill, Baby... Kill!, regarded by Martin Scorsese as Bava's masterpiece, also appear in the Asian strain of terror film known as J-horror. 1971's A Bay of Blood is considered one of the earliest slasher films, and was explicitly imitated in Friday the 13th Part 2.
 Passage 3:A member of the Aspietes family, of noble Armenian origin, Constantine was probably a close relative of his contemporary Michael Aspietes, a distinguished general killed in 1176. Like his relative, Constantine too had earned distinction during Manuel I Komnenos' campaign against the Hungarians in 1167. The historian John Kinnamos records that he held the rank of sebastos. He is next recorded as being active in 1190/1, during the Byzantine efforts to suppress the Bulgarian–Vlach rebellion of the brothers Peter and Ivan Asen. The historian Niketas Choniates records that, in an effort to sustain the troops and bolster their morale, Aspietes decided to distribute to them their delayed annual salaries. This act, however, enraged Emperor Isaac II Angelos, who saw in it almost an attempt to bribe the army to support Aspietes in overthrowing him. The emperor had Aspietes arrested and blinded, after which nothing further is known of him. He possibly died in the early years of the 13th century.

[EX Q]: Question: In what year was Kyman first used? Passage 1:Jackson ran again in 1828, defeating Adams in a landslide. Jackson faced the threat of secession by South Carolina over what opponents called the "Tariff of Abominations." The crisis was defused when the tariff was amended, and Jackson threatened the use of military force if South Carolina attempted to secede. In Congress, Henry Clay led the effort to reauthorize the Second Bank of the United States. Jackson, regarding the Bank as a corrupt institution, vetoed the renewal of its charter. After a lengthy struggle, Jackson and his allies thoroughly dismantled the Bank. In 1835, Jackson became the only president to completely pay off the national debt, fulfilling a longtime goal. His presidency marked the beginning of the ascendancy of the party "spoils system" in American politics. In 1830, Jackson signed the Indian Removal Act, which forcibly relocated most members of the Native American tribes in the South to Indian Territory. The relocation process dispossessed the Indians and resulted in widespread death and disease. Jackson opposed the abolitionist movement, which grew stronger in his second term. In foreign affairs, Jackson's administration concluded a "most favored nation" treaty with Great Britain, settled claims of damages against France from the Napoleonic Wars, and recognized the Republic of Texas. In January 1835, he survived the first assassination attempt on a sitting president.
 Passage 2:Autechre use many different digital synths and a few analogue synths in their production, as well as analogue and digital drum machines, mixers, effects units and samplers. They have also made extensive use of a variety of computer based sequencers, software synthesisers, and other applications as a means of controlling those synths and processing the synthesised sounds. Much of the hardware and software they use has been customised by the band themselves. Autechre have also experimented in depth with development environments such as Max/MSP, and Kyma, amongst others, from 1997 onwards. From 2005 until 2009, they have used the Elektron Machinedrum and Monomachine, alongside Akai MPC and Nord Modular in their live performances. It has also been rumoured that Autechre have used military equipment in their work. In 2008, Sean Booth reported that if he were locked in a cell for a year with only one piece of software and one piece of hardware, he'd "probably take a copy of Digital Performer and an AKG C 1000 microphone." Other machines that Autechre have repeatedly mentioned in interviews are appreciated for their interface and aesthetics as much as their sound, including the Roland TR-606 and MC-202, and the Nord Lead. According to the 2016 interview to Resident Advisor, both members haven't bought a piece of equipment "in the last 5 years", making MAX/MSP a primary production method, with Sean Booth stating that "in Max I can generally build the thing I need, and if I don't know how to do that it'll generally be worthwhile learning."
 Passage 3:Hasan was born in Medina around 844. Hasan's father was a descendant of Husayn ibn Ali, the grandson of Muhammad and third Shi'a Imam, via his eldest son Zayn al-Abidin, while his mother was an unnamed Khurasani slave. When Hasan ibn Zayd, a descendant of Husayn's brother Hasan, established his rule over Tabaristan in the 860s, Hasan joined him there. However, he eventually fell out with Hasan ibn Zayd's brother and successor, Muhammad ibn Zayd, who distrusted him. Hasan left Tabaristan and tried to set up a realm of his own in the provinces further east. To this end, he allied himself with the ruler of Khurasan, Muhammad ibn Abdallah al-Khujistani, who was an enemy of Muhammad ibn Zayd. Soon, however, al-Khujistani too came to distrust him and had him imprisoned and scourged, as a result of which he lost his hearing and received the sobriquet al-Utrush ("the Deaf"), by which he is known.
