Input: Consider Input: Question: What kind of aircraft were leased? Passage:In addition to withdrawing from the prestigious long-haul routes to New York and Los Angeles after only 18 months, other specific measures the airline took at the time to ensure its survival included dropping all scheduled flights to Belfast, Copenhagen, Gibraltar, Ibiza, Málaga, Palma de Mallorca and Tunis, indefinitely suspending scheduled services on the Glasgow—Southampton route as well as cutting the number of frequencies on the Gatwick—Glasgow and Gatwick—Edinburgh routes from six to four daily round trips. Two surplus aircraft were leased out to Air Malta and Austrian Airlines respectively for the duration of the 1975 summer timetable period. Another aircraft was stationed at West Berlin's Tegel Airport during the month of July of that year to fulfill a short-term charter contract to carry Turkish migrant workers to and from Istanbul on behalf of a local tour operator. BCal also decided to increase its 707 freighter fleet from one to four aircraft and to acquire a five-seater Piper Aztec to serve the rapidly growing executive charter market. These changes left BCal with 25 operational aircraft for the 1975 summer season. To reduce operating costs further, the airline decided to contract out its scheduled operations between Gatwick and Le Touquet to BIA. The reason for replacing BCal's One-Eleven 200 jet aircraft on this route with that airline's Herald turboprops at the beginning of the 1975 summer timetable period was the high price of jet fuel, which had made BCal's own jet aircraft operations uneconomic.

Input: Consider Input: Question: Where in Kentucky is the race held in which Parole finished 4th in 1876? Passage:An avid sportsman, Pierre Lorillard and his brother, George Lyndes Lorillard, were both major figures in Thoroughbred horse racing. In 1874, Pierre's horse, Saxon, won the Belmont Stakes. Although his horse Parole finished fourth in the 1876 Kentucky Derby, it went on to race with considerable success both in the United States and in Europe. In the 19th century, shipping horses from New York to Louisville, Kentucky was a major undertaking and as the Preakness Stakes and the Belmont Stakes were both held in the New York City area in the period, neither of the Lorillard brothers entered horses again in the Kentucky Derby. Pierre Lorillard established Rancocas Stable, named for the New Jersey town where he owned a country house. He spent time in Paris and in England where, in 1881, his horse Iroquois became the first American-owned and bred horse to win a European classic race. Ridden by the champion English jockey Fred Archer, Iroquois won The Derby and then went on to capture the St. Leger Stakes as well. Lorillard had other successes in England, notably with the horse named for the actor David Garrick, which won the 1901 Chester Cup ridden by American jockey, Danny Maher.

Input: Consider Input: Question: How old was The PRI candidate for the 1994 elections when he died? Passage:Salinas assumed the presidency on 1 December 1988 at the Legislative Palace of San Lázaro. There he took oath before the Congress of the Union. As the declared winner of a highly contested election, he had the task of restoring his own legitimacy and that of his party when he took office. The election had shown that much of the public desired reform, but Salinas appointed PRI hard-liners ("dinosaurs") to his cabinet, including Fernando Gutiérrez Barrios to the Ministry of the Interior; Manuel Bartlett to the Ministry of Education; and Carlos Hank González to Agriculture. The cabinet was cohesive in support of Salinas's neoliberal policies. Many ministers were technocrats with graduate academic degrees, a profile similar to Salinas's. Although there was opposition to many of Salinas's policies, it came from outside the cabinet. Over the course of his presidency, he moved or replaced a number of . A key replacement in January 1994 immediately after the Chiapas conflict was at the Ministry of the Interior (Gobernación), appointing Jorge Carpizo, who had been head of the government National Human Rights Commission and previously was rector of the National Autonomous University of Mexico. When the PRI candidate in the 1994 elections, Luis Donaldo Colosio was assassinated in March 1994, new restrictions barring cabinet ministers who had not resigned in the six months previous to the election date from being candidates for the presidency meant that Salinas had a small pool of eligible choices.
