Passage 1:Usenicnik was born in the village of Poljane near the Upper Carniolan town of Skofja Loka, in what was then the Austro-Hungarian Empire (now in Slovenia). He studied theology at the Pontifical Gregorian University in Rome. In 1897, he became a professor at the Theological Seminary in Ljubljana. In 1919, he became a professor at the Faculty of Theology at the University of Ljubljana, where he taught philosophy. In 1922 and 1923, he served as the fourth chancellor of the University of Ljubljana. In 1937, he became a member of the Pontifical Academy of St. Thomas Aquinas and in 1938 one of the founding members of the Academy of Sciences and Arts in Ljubljana (later renamed the Slovenian Academy of Sciences and Arts). In 1948, he was expelled from the academy by the new communist regime. His membership was reinstated in 1996 after the collapse of communism.
Passage 2:The video begins with an introduction of Dr. Dre's music career, such as when he and fellow N.W.A member DJ Yella were in the 1980s funk group World Class Wreckin' Cru. There are also scenes of Dr. Dre and his family, such as him hugging his daughter and son and getting married. There are also snippets from past music videos. It includes many rappers such as Eazy-E, 2Pac, The D.O.C, Snoop Dogg, Warren G, Eminem, Xzibit and all the rest of the members from N.W.A. The video then features Dr. Dre driving down Pacific Coast Highway in a Ferrari 360, with flashbacks of his life, crashing his car and the last thing heard was his daughter say "Good night Daddy." Then he is transported to a medical facility. The date at the beginning of the video is February 18, 2001 (his 36th birthday). They fast-forward to present day ten years later, where he has been hospitalized and is on life support. The Marin County Civic Center stands in for the medical facility. Eminem raps next to him as he is floating in an isolation tank, during which the figure of the Pythia (played by Canadian actress Estella Warren) is singing as a hologram behind and over Dre, mouthing the words to Skylar Grey's vocal part in the song. Skylar Grey herself appears as one of the doctors in the video, but never actually appears singing her part. Dre eventually wakes up and goes through rehab, and the video ends with him standing next to the grave of Eazy-E, a rapper who had launched Dre's music career by founding N.W.A and was also a member along with Ice Cube, MC Ren and DJ Yella. A ticking clock is heard midway through the video. The music video received complaints of being an "act of advertising" for a variety of product placements, such as Ferrari, G-Shock, HP, Gatorade, and Dr. Dre's signature headphones, Beats by Dr. Dre.

Passage 2:Hirst was born in 1838 in Huddersfield, Yorkshire, England. He received his education at Huddersfield College. He arrived at Port Chalmers in Otago on the Agra on 30 October 1858 and first settled in the Te Anau / Manapouri area in Southland. Together with John Charles Watts-Russell of Christchurch, he explored Breaksea Sound for open land for sheep farming, but they were unsuccessful in this venture. Next, Hirst settled at Riverton where he had a butchery. In 1860, he married a daughter of William Dallas. In August 1861, he was the first who managed to drive cattle from Southland to the Gabriel's Gully gold field during the Otago Gold Rush. Some time later, Hirst was farming at Orepuki. When gold was discovered in the locality in 1866, the government resumed the land that he was farming, and he bought another property in the town where he lived for the rest of his life.
Passage 3:The Tigers improved again in the 19801981 season. In fact, it would be the winningest year in LSU history. This year, Dale Brown took his team to the Final Four, the second in LSU history, and the first of the Dale Brown era. The team finished 315 (most wins in the nation) and won the conference championship with a 171 record. The team also set a school record winning 26 straight games, including its first 17 conference games and the only SEC team to ever win 17 consecutive league games in the same season with only a loss to powerhouse Kentucky in Rupp Arena stopping LSU from becoming the only team to complete an 18-game SEC slate with an unblemished mark. Rudy Macklin was an All-American, as well as First Team All SEC. Ethan Martin also made First Team All SEC, and Howard Carter made the Second Team. LSU advanced to the Final Four by beating Wichita State 9685 in the Elite 8 round of the 1981 NCAA tournament, played in front of home-state fans in the Louisiana Superdome. To reach the regional final, LSU defeated future SEC rival Arkansas, coached at the time by Eddie Sutton, who would tangle with Brown for four seasons at Kentucky.

Question: How old was Kennedy when he was assassinated? Passage 1:During the Napoleonic wars, Ile de France became a base from which the French navy, including squadrons under Rear Admiral Linois or Commodore Jacques Hamelin, and corsairs such as Robert Surcouf, organised raids on British merchant ships. The raids (see Battle of Pulo Aura and Mauritius campaign of 18091811) continued until 1810 when the British sent a strong expedition to capture the island. The first British attempt, in August 1810, to attack Grand Port resulted in a French victory, one celebrated on the Arc de Triomphe in Paris. A subsequent and much larger attack launched in December of the same year from Rodrigues, which had been captured a year earlier, was successful. The British landed in large numbers in the north of the island and rapidly overpowered the French, who capitulated (see Invasion of Isle de France). In the Treaty of Paris (1814), the French ceded Ile de France together with its territories including Rodrigues and Seychelles to Great Britain. The island then reverted to its former name, 'Mauritius'.
Passage 2:1964 is a documentary film produced by Insignia Films for the American Experience series about political, social and cultural events in the United States for the calendar year 1964. It is based partly on Jon Margolis book The Last Innocent Year: America in 1964. The documentary depicts the year 1964 as significant and epic in that following the assassination of President John F. Kennedy in late 1963, 1964, as a presidential election year, becomes a departure point for American history, with lasting effects today. It is also the year of the British Invasion led by the Beatles, when Cassius Clay fights Sonny Liston for the World Heavyweight Championship, the year after Betty Friedan's book, The Feminine Mystique, is published, and the year Republican activist, Phyllis Schlafly's book, A Choice, Not an Echo, is published. It is also the year of Freedom Summer, an initiative by the Student Nonviolent Coordinating Committee to register African-Americans in Mississippi, the subsequent murders of Chaney, Goodman, and Schwerner, three CORE activists, in Mississippi by white supremacists that created a national sensation, and the Harlem riot of 1964, culminating in the Berkeley Free Speech Movement at the University of California at Berkeley. A recurrent theme of the film is its departure as a presidential election year, with President Lyndon B. Johnson running as the expected Democratic Party nominee and the nomination of U.S. Senator Barry Goldwater selected through a grassroots campaign for the Republican nomination for President of the United States, that defines the future divisions of the US political party competition.
Passage 3:As a boy, Roebuck worked as a trammer and after being sentenced to one month's imprisonment for stealing a watch in 1904, he enlisted in the York and Lancaster Regiment. Over the next seven years, he was stationed in India and Ireland and was promoted to lance corporal, but was demoted back to private in 1910 for "misconduct". He married in 1908 and had two children. Roebuck was discharged into the reserves in 1912 and likely returned to work as a miner prior to becoming a professional footballer in 1913. After Britain's entry into the First World War in August 1914, he was called up by the York and Lancaster Regiment and arrived on the Western Front in September 1914. On 18 October 1914, Roebuck recorded as "presumed dead" after an attack near Beaucamps-Ligny during the Race to the Sea. His death was confirmed by two comrades in January 1915. Roebuck is commemorated on the Ploegsteert Memorial to the Missing.
