[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: When was the show with the deleted scene in which Kenneth claims his parents were first cousins released? Passage 1:Within this scheme, Dwight D. Eisenhower offered a 25 million dollar loan to the Saudi Government on 24 January 1957. In return, King Saud explained that he had refused Soviet Union military aid to fight Britain, and that Britain's policy was what urged the Arabs to seek the Soviet Union's help. He also stressed that non-aligned countries were benefiting from Soviet aid more than the American allied countries were benefiting from American aid. He considered that this aid should double if the American President wished to succeed in his endeavors. King Saud asked Dwight D. Eisenhower to exert pressure on Israel to withdraw from the occupied territories of Palestine and settle the Palestinian cause, and to convince France to reach a settlement regarding the independence of Algeria. On the other hand, he promised to inform the Arabs of the Eisenhower Doctrine and its purposes; and to inquire about the Arab reaction on the official and officious levels before making any commitments. King Saud explained to the American President that a large bulk of his country's budget was allocated to development projects and to the five-year plan and that he needed military aid before being able to play any role expected from him in fighting communism. The American government agreed to give him a 250 million dollar loan and all kinds of land, sea and air weaponry, and to train the Saudi army on how to use them.
 Passage 2:Kenneth has a close relationship with his mother; he considers her to be his best friend and credits her with his optimism; she taught him that no matter how bad things seem, there is always someone else having a worse day "like being stung by a bee, or getting a splinter, or being chained to a wall in someone's sex dungeon". Apart from pig farming, not much else is known about Kenneth's father, although, in a deleted scene of "The One with the Cast of Night Court", Kenneth tells Tracy that his parents were first cousins (something which Kenneth's father never revealed to Kenneth's mother, as his father knew that if she knew of their relation, she would have not married him); however, contrary to this, in "Grandmentor", he tells Hazel Wassername that his parents were "technically brothers". In "The Collection", he tells Jenna that his father died of a heart attack. In "Alexis Goodlooking and the Case of the Missing Whisky" it is implied that Kenneth's father was the infamous D. B. Cooper, as that alias is seen on a sewn-in patch label on the inside of one of his father's former suits. Kenneth also relays his father's final words to Jack: "Son, if you want to get ahead in this world—oh God, this hurts! Tell your mother I'm gay!". After Kenneth's father died, his mother's "friend" Ron moved in with him and his mother. Many of Kenneth's comments about his mother and Ron suggest that the two had a sexual relationship, but Kenneth appears to be unaware of this, although, it is implied that he has a great hatred towards him (Kenneth once stated that he knew Tracy Jordan like "the back of [his] step-father Ron's hand"). In "Governor Dunston", Ron and Kenneth's mother, Pearlene (played by Bryan Cranston and Catherine O’Hara, respectively), visit Kenneth, and, contrary to what Kenneth's comments portrayed him to be, Ron is a benign and amiable, if somewhat dim-witted, man who is shown to care for him like a father. Kenneth, however, still retains his dislike of him, which only increases when Ron accidentally lets it slip that he and Pearlene got married seven years earlier, something which Kenneth was unaware of (contradicting the previous quote) and is not pleased about. But, by the end of the episode, he comes to accept Ron as a part of the family.
 Passage 3:Several team changes took place before the season began. Haas F1 Team, a team formed by NASCAR Sprint Cup Series team owner Gene Haas, joined the Formula One grid, becoming the first American team to compete since the unrelated Haas Lola team competed in 1986. The team used power units supplied by Ferrari and a chassis developed by Dallara. Dallara had last participated in Formula One as the chassis manufacturer for HRT in . Renault returned to Formula One as a full factory-supported team after they purchased Lotus from Genii Capital, the venture capital firm they had originally sold the same team to in 2010, and supplied engines to up until the end of . Lotus's participation in the 2016 season was in question pending the resolution of a High Court case brought against the team by HM Revenue and Customs over unpaid PAYE tax.

[EX Q]: Question: What other famous people came out of where The Beatles were based? Passage 1:Anne Beloff was born in 1921 in Hampstead to Simon Beloff and Marie Katzin. Her parents were of Russian–Jewish background, and her siblings included the historian Max Beloff, Baron Beloff, the psychologist John Beloff, the journalist Nora Beloff, and the politician Renee Soskin. She earned a degree in chemistry from University College London in 1942 before completing a PhD in the biochemistry of skin burns with Rudolph Peters at the University of Oxford. She visited Harvard Medical School in 1946 to perform research and returned to the UK in 1948. In the same year she married Ernst Boris Chain, a biochemist who had won the Nobel Prize in Physiology or Medicine in 1945, and moved with him to Rome.
 Passage 2:Bieberbach wrote a habilitation thesis in 1911 about groups of Euclidean motions – identifying conditions under which the group must have a translational subgroup whose vectors span the Euclidean space – that helped solve Hilbert's 18th problem. He worked on complex analysis and its applications to other areas in mathematics. He is known for his work on dynamics in several complex variables, where he obtained results similar to Fatou's. In 1916 he formulated the Bieberbach conjecture, stating a necessary condition for a holomorphic function to map the open unit disc injectively into the complex plane in terms of the function's Taylor series. In 1984 Louis de Branges proved the conjecture (for this reason, the Bieberbach conjecture is sometimes called de Branges' theorem). There is also a on space groups. In 1928 Bieberbach wrote a book with Issai Schur titled Über die Minkowskische Reduktiontheorie der positiven quadratischen Formen.
 Passage 3:The recordings made by the Beatles, a rock group from Liverpool, England, from their inception as the Quarrymen in 1957 to their break-up in 1970 and the reunion of their surviving members in the mid-1990s, have huge cultural and historical value. The studio session tapes are kept at Abbey Road Studios, formerly known as "EMI Recording Studios," where the Beatles recorded most of their music. While most have never been officially released, their outtakes and demos are seen by fans as collectables, and some of the recordings have appeared on countless bootlegs. Until 2013, the only outtakes and demos to be officially released were on The Beatles Anthology series and its tie-in singles, and bits of some previously unreleased studio recordings were used in  video game as ambient noise and to give songs studio-sounding beginnings and endings. In 2013, Apple Records released the album The Beatles Bootleg Recordings 1963, which includes previously unreleased outtakes and demos from 1963, to stop the recordings from falling into the public domain.
