[EX Q]: Question: What was the population of Augusta the year the Knickerbocker chimney was demolished? Passage:In 1852, Farmingdale incorporated as a town, combining parts of South Hallowell, North Gardiner and East/West Gardiner. Many businesses existed in Farmingdale, most of them along the Kennebec River. A major business was harvesting and selling ice worldwide. The Knickerbocker Ice Company (the largest ice company in the country), and the Marshall Ice Company had ice-houses at Bowman's Point. The Knickerbocker Ice Company burned in 1894 or 1895 leaving only the chimney that stood until it was demolished in 1911 to make room for the Central Maine Power Plant. Other businesses on the river in Farmingdale included shipyards, brickyards, pottery, and a glue factory. Commercial growth in ensuing years centered in Gardiner, Hallowell and Augusta, while Farmingdale never developed a town center to compare with those cities. Time, fires, floods and economic forces eventually removed the larger businesses. Today, Farmingdale exists largely as a strong and vibrant residential community whose residents work primarily in other cities. The distinction between the densely developed riverbanks and the open rural back-land remains. Structures that are on the National Register of Historic Places include the Peter Grant House, and the Captain Nathaniel Stone House.

[EX A]: The Knickerbocker Ice Company burned in 1894 or 1895 leaving only the chimney that stood until it was demolished in 1911 to make room for the Central Maine Power Plant

[EX Q]: 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 DamusKayeStansel procedure to connect the aortic and pulmonary roots, allowing the coronary arteries to remain perfused. It was first described in 1987.
