Input: Read this: Some street trams (streetcars) used conduit third-rail current collection. The third rail was below street level. The tram picked up the current through a plough (U.S. "plow") accessed through a narrow slot in the road. In the United States, much (though not all) of the former streetcar system in Washington, D.C. (discontinued in 1962) was operated in this manner to avoid the unsightly wires and poles associated with electric traction. The same was true with Manhattan's former streetcar system. The evidence of this mode of running can still be seen on the track down the slope on the northern access to the abandoned Kingsway Tramway Subway in central London, United Kingdom, where the slot between the running rails is clearly visible, and on P and Q Streets west of Wisconsin Avenue in the Georgetown neighborhood of Washington DC, where the abandoned tracks have not been paved over. The slot can easily be confused with the similar looking slot for cable trams/cars (in some cases, the conduit slot was originally a cable slot). The disadvantage of conduit collection included much higher initial installation costs, higher maintenance costs, and problems with leaves and snow getting in the slot. For this reason, in Washington, D.C. cars on some lines converted to overhead wire on leaving the city center, a worker in a "plough pit" disconnecting the plough while another raised the trolley pole (hitherto hooked down to the roof) to the overhead wire. In New York City for the same reasons of cost and operating efficiency outside of Manhattan overhead wire was used. A similar system of changeover from conduit to overhead wire was also used on the London tramways, notably on the southern side; a typical changeover point was at Norwood, where the conduit snaked sideways from between the running rails, to provide a park for detached shoes or ploughs.
Question: What area in US discontinued using overhead wires for streetcars in 1962?

Output: Washington, D.C.

Input: Read this: The school broke off from the University of Deseret and became Brigham Young Academy, with classes commencing on January 3, 1876. Warren Dusenberry served as interim principal of the school for several months until April 1876 when Brigham Young's choice for principal arriveda German immigrant named Karl Maeser. Under Maeser's direction the school educated many luminaries including future U.S. Supreme Court Justice George Sutherland and future U.S. Senator Reed Smoot among others. The school, however, did not become a university until the end of Benjamin Cluff, Jr's term at the helm of the institution. At that time, the school was also still privately supported by members of the community and was not absorbed and sponsored officially by the LDS Church until July 18, 1896. A series of odd managerial decisions by Cluff led to his demotion; however, in his last official act, he proposed to the Board that the Academy be named "Brigham Young University". The suggestion received a large amount of opposition, with many members of the Board saying that the school wasn't large enough to be a university, but the decision ultimately passed. One opponent to the decision, Anthon H. Lund, later said, "I hope their head will grow big enough for their hat."
Question: When did the Latter Day Saints Church acknowledge and begin to support BYU?

Output: July 18, 1896

Input: Read this: In 677 (during the reign of Emperor Gaozong), Chen Zheng (), together with his son Chen Yuanguang (), led a military expedition to pacify the rebellion in Fujian. They settled in Zhangzhou and brought the Middle Chinese phonology of northern China during the 7th century into Zhangzhou; In 885, (during the reign of Emperor Xizong of Tang), the two brothers Wang Chao () and Wang Shenzhi (), led a military expedition force to pacify the Huang Chao rebellion. They brought the Middle Chinese phonology commonly spoken in Northern China into Zhangzhou. These two waves of migrations from the north generally brought the language of northern Middle Chinese into the Fujian region. This then gradually evolved into the Zhangzhou dialect.
Question: What dialect did the migrations from the south help to develop?

Output: unanswerable

Input: Read this: Though almost any variety of acoustic mandolin might be adequate for Irish traditional music, virtually all Irish players prefer flat-backed instruments with oval sound holes to the Italian-style bowl-back mandolins or the carved-top mandolins with f-holes favoured by bluegrass mandolinists. The former are often too soft-toned to hold their own in a session (as well as having a tendency to not stay in place on the player's lap), whilst the latter tend to sound harsh and overbearing to the traditional ear. The f-hole mandolin, however, does come into its own in a traditional session, where its brighter tone cuts through the sonic clutter of a pub. Greatly preferred for formal performance and recording are flat-topped "Irish-style" mandolins (reminiscent of the WWI-era Martin Army-Navy mandolin) and carved (arch) top mandolins with oval soundholes, such as the Gibson A-style of the 1920s.
Question: Why is it said that the Italian style can hold their own session?

Output:
unanswerable
