Question: What city was Jet Ski Lady's last race in? Passage:Jet Ski Lady (foaled 20 February 1988) was an American-bred, Irish-trained thoroughbred racehorse, best known for winning The Oaks in 1991. In a racing career which lasted from June 1990 to October 1991 the filly ran ten times and won four races. After winning twice as a two-year-old, Jet Ski Lady competed against colts with mixed success in early 1991 before winning the Classic Oaks over one and a half miles at Epsom Downs Racecourse. Her winning margin of ten lengths was the second-widest in the race's history and her starting price of 50/1 made her the equal longest-priced winner of the Oaks on records. She subsequently finished second in both the Irish Oaks at the Curragh and the Yorkshire Oaks at York. She was retired to stud after finishing unplaced in the Prix de l'Arc de Triomphe.

Question: When was the author of JFK and the Unspeakable born? Passage:Jim Garrison said anti-Communist and anti-Castro extremists in the CIA plotted the assassination of Kennedy to maintain tension with the Soviet Union and Cuba, and to prevent a United States withdrawal from Vietnam. James Douglass wrote in JFK and the Unspeakable that the CIA, acting upon the orders of conspirators with the "military industrial complex", killed Kennedy and in the process set up Lee Harvey Oswald as a patsy. Like Garrison, Douglass stated that Kennedy was killed because he was turning away from the Cold War and pursuing paths of nuclear disarmament, rapprochement with Fidel Castro, and withdrawal from the war in Vietnam. Mark Lane — author of Rush to Judgment and Plausible Denial and the attorney who defended Liberty Lobby against a defamation suit brought by former CIA agent E. Howard Hunt — has been described as a leading proponent of the theory that the CIA was responsible for the assassination of Kennedy. Others who believe the CIA was involved include authors Anthony Summers and John M. Newman.

Question: Of the venues in which Longaretti exhibited his works in 1942, which was the newest? Passage:Upon completion of his degree studies at Brera in early 1939, he was drafted by the Italian military for service in World War II. He was deployed to Slovenia, and later to Sicily and Albania, and when his tours of duty were complete, he would participate in art exhibitions. He continued to paint during his service, even when on the front lines, committing to canvas images of "dramatic testimonials" considered prohibited, such as Albanian villages razed by Italian troops. At the end of the war, he also began working on frescoes, glass art, and mosaic art. In 1942, he exhibited works at the Venice Biennale and at the Mostra degli artisti in armi ("Artists in arms") exhibit at the Palazzo delle Esposizioni in Rome, where he presented three watercolours and seven pen drawings, all having a war theme. By this time, he was a sergeant for the Genio Ferrovieri. His first personal exhibition occurred in 1943 and was presented by Raffaello Giolli at the Galleria La Rotonda in Bergamo. He dedicated himself to teaching and the creation of works of sacred art in 1945. He would exhibit at the Venice Biennale again in 1948, 1950, 1956, and 2011, and was invited to exhibit at the Rome Quadriennale in 1952.
