question:
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:
Question: How many species of the Aru Flying fox are there? Passage:Of the 62 flying fox species evaluated by the IUCN as of 2018, 3 are considered critically endangered: the Aru flying fox, Livingstone's fruit bat, and the Vanikoro flying fox. Another 7 species are listed as endangered; 20 are listed as vulnerable, 6 as near threatened, 14 as least concern, and 8 as data deficient. A further 4 are listed as extinct: the dusky flying fox, the large Palau flying fox, the small Mauritian flying fox, and the Guam flying fox. Over half of the species are threatened today with extinction, and in particular in the Pacific, a number of species have died out as a result of hunting, deforestation, and predation by invasive species. Six flying fox species are believed to have gone extinct from 1864 to 2014: the Guam, large Palau, small Mauritian, dusky, large Samoan, and the small Samoan flying foxes.

question:
Question: Where was the Rear-Admiral who relieved King-Hall born? Passage:Orion, named after the mythological hunter, Orion, was the fourth ship of her name to serve in the Royal Navy (RN). The ship was laid down at HM Dockyard, Portsmouth on 29 November 1909. She was launched on 20 August 1910, and was commissioned on 2 January 1912. Including her armament, her cost is variously quoted at £1,855,917 or £1,918,773. Orion was assigned to the 2nd division of the Home Fleet as the flagship of Rear-Admiral Sir Herbert King-Hall, the division's second-in-command. The ship was slightly damaged on 7 January when the pre-dreadnought battleship broke loose from her moorings and collided with Orions bow. The division was redesignated as the 2nd Battle Squadron (BS) on 1 May. The ship, together with her sister ships and , participated in the Parliamentary Naval Review on 9 July at Spithead. They then participated in training manoeuvres. King-Hall was relieved by Rear-Admiral Rosslyn Wemyss on 29 October. On 13 November, the ship participated in comparative gunnery trials with Thunderer to evaluate the effectiveness of the latter's gunnery director. Thunderer decisively outshot Orion, although some of her success was because her director was above the smoke that obscured the target from Orions guns. The test was repeated in better conditions on 4 December and Orion performed much better, apparently beating Thunderer. The three sisters were present with the 2nd BS to receive the President of France, Raymond Poincaré, at Spithead on 24 June 1913 and then participated in the annual fleet manoeuvres in August. Wemyss was relieved in his turn by Rear-Admiral Sir Robert Arbuthnot, 4th Baronet on 28 October. Captain Frederic Dreyer assumed command of Orion that same day. On 4 November, Orion, Thunderer, the dreadnought and the predreadnought fired at and sank the target ship to give their crews experience in firing live ammunition against a real ship.
