Question: Question: When was the building where the heads of the major railroads met in 1883 erected? Passage:In 1870, Charles F. Dowd proposed four time zones based on the meridian through Washington, DC for North American railroads. In 1872. he revised his proposal to base it on the Greenwich meridian. Sandford Fleming, a Scottish-born engineer operating in Canada, proposed worldwide Standard Time at a meeting of the Royal Canadian Institute on February 8, 1879. Cleveland Abbe advocated standard time to better coordinate international weather observations and resultant weather forecasts, which had been coordinated using local solar time. In 1879 he recommended four time zones across the contiguous United States, based upon Greenwich Mean Time. The General Time Convention (renamed the American Railway Association in 1891), an organization of US railroads charged with coordinating schedules and operating standards, became increasingly concerned that if the US government adopted a standard time scheme it would be disadvantageous to its member railroads. William F. Allen, the Convention secretary, argued that North American railroads should adopt a five-zone standard, similar to the one in use today, to avoid government action. On October 11, 1883, the heads of the major railroads met in Chicago at the Grand Pacific Hotel and agreed to adopt Allen's proposed system.

Question: Question: How old was the person who broke King's record in 1925? Passage:In April 1914 he joined Arsenal for a £1,000 fee, returning to League football. Arsenal had just missed out on promotion on goal average to the First Division, and in 1914–15 King spearheaded their attack, scoring 26 goals in the League and another three in the FA Cup. These included the first hat trick scored at their new Highbury stadium (against Grimsby Town on 14 November 1914), and two four-goal hauls against Wolverhampton Wanderers and Nottingham Forest. King's 29 goals that season were an all-time club record at the time, remaining so until Jimmy Brain broke it in 1925–26. However, Arsenal's defence let them down and they only finished fifth, outside of the promotion places; eventually, they were re-elected back to the First Division when football resumed after the end of the First World War.

Question: Question: How many President's children have lived in the White House? Passage:Within weeks, many Americans could recite favorite lines from the record, including "the rubber schwan [swan] is mine", and "move ahead...with great vigah [vigor]", the latter lampooning the President's own words. The album poked fun at Kennedy's PT-109 history; the rocking chairs he used for his painful back; the Kennedy clan's well-known athleticism, football games and family togetherness; children in the White House; and Jackie Kennedy's soft-spoken nature and her redecoration of the White House; and many other bits of knowledge that the public was eager to consume. Kennedy himself was said to have given copies of the albums as Christmas gifts, and once greeted a Democratic National Committee group by saying, "Vaughn Meader was busy tonight, so I came myself." According to UPI reporter Merriman Smith, during a Cabinet meeting Kennedy played the entire record for everyone. At one press conference, Kennedy was asked if the album had produced "annoyment (sic) or enjoyment." He jokingly responded, "I listened to Mr. Meader's record and, frankly, I thought it sounded more like Teddy than it did me. So, now he's annoyed."
