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.

Question: How tall is the mountain that is south of the canyon? Passage:Granite Canyon is located in Grand Teton National Park, in the U. S. state of Wyoming. The canyon was formed by glaciers which retreated at the end of the last glacial maximum approximately 15,000 years ago, leaving behind a U-shaped valley. The canyon lies between Rendezvous Mountain to the south and Mount Hunt to the north. The trailhead for the canyon is on the Moose–Wilson Road about north of Teton Village. One of the most popular hikes from the trailhead is to Marion Lake by way of the Granite Canyon Trail which traverses the length of the canyon. Another popular hike involves riding the aerial tram located at the Jackson Hole Mountain Resort in Teton Village to the top of Rendezvous Mountain, and then descending back to Teton Village by way of Granite Canyon. The descent from the summit of Rendezvous Peak back to Teton Village is an often steep one with an altitude loss of . The historic Upper Granite Canyon Patrol Cabin is situated near the entrance to the canyon and was listed on the National Register of Historic Places in 1998.

Question: What are the effects of hypoplastic left heart syndrome? Passage:The Yasui procedure is a pediatric heart operation used to bypass the left ventricular outflow tract (LVOT) that combines the aortic repair of the Norwood procedure and a shunt similar to that used in the Rastelli procedure in a single operation. It is used to repair defects that result in the physiology of hypoplastic left heart syndrome even though both ventricles are functioning normally. These defects are common in DiGeorge syndrome and include interrupted aortic arch and LVOT obstruction (IAA/LVOTO); aortic atresia-severe stenosis with ventricular septal defect (AA/VSD); and aortic atresia with interrupted aortic arch and aortopulmonary window. This procedure allows the surgeon to keep the left ventricle connected to the systemic circulation while using the pulmonary valve as its outflow valve, by connecting them through the ventricular septal defect. The Yasui procedure includes a modified Damus–Kaye–Stansel procedure to connect the aortic and pulmonary roots, allowing the coronary arteries to remain perfused. It was first described in 1987.
