Input: Read this: Elevators with more than 30 m (98 ft) of travel have a system called compensation. This is a separate set of cables or a chain attached to the bottom of the counterweight and the bottom of the elevator cab. This makes it easier to control the elevator, as it compensates for the differing weight of cable between the hoist and the cab. If the elevator cab is at the top of the hoist-way, there is a short length of hoist cable above the car and a long length of compensating cable below the car and vice versa for the counterweight. If the compensation system uses cables, there will be an additional sheave in the pit below the elevator, to guide the cables. If the compensation system uses chains, the chain is guided by a bar mounted between the counterweight railway lines.
Question: What exactly does this system compensate for?

Output: the differing weight of cable between the hoist and the cab


Input: Read this: There have been indications since 1996 that Everton will move to a new stadium. The original plan was for a new 60,000-seat stadium to be built, but in 2000 a proposal was submitted to build a 55,000 seat stadium as part of the King's Dock regeneration. This was unsuccessful as Everton failed to generate the £30 million needed for a half stake in the stadium project, with the city council rejecting the proposal in 2003. Late in 2004, driven by Liverpool Council and the Northwest Development Corporation, the club entered talks with Liverpool F.C. about sharing a proposed stadium on Stanley Park. Negotiations broke down as Everton failed to raise 50% of the costs. On 11 January 2005, Liverpool announced that ground-sharing was not a possibility, proceeding to plan their own Stanley Park Stadium.
Question: What team did Everton FC consider sharing grounds with around the year 2000?

Output: Liverpool


Input: Read this: The Party of Reconstruction in Sicily, which claimed 40,000 members in 1944, campaigned for Sicily to be admitted as a U.S. state. This party was one of several Sicilian separatist movements active after the downfall of Italian Fascism. Sicilians felt neglected or underrepresented by the Italian government after the annexation of 1861 that ended the rule of the Kingdom of the Two Sicilies based in Naples. The large population of Sicilians in America and the American-led Allied invasion of Sicily in July–August 1943 may have contributed to the sentiment.
Question: When did the annexation of Naples by Italy happen?

Output: unanswerable


Input: Read this: Greenwich Mean Time (GMT) is an older standard, adopted starting with British railways in 1847. Using telescopes instead of atomic clocks, GMT was calibrated to the mean solar time at the Royal Observatory, Greenwich in the UK. Universal Time (UT) is the modern term for the international telescope-based system, adopted to replace "Greenwich Mean Time" in 1928 by the International Astronomical Union. Observations at the Greenwich Observatory itself ceased in 1954, though the location is still used as the basis for the coordinate system. Because the rotational period of Earth is not perfectly constant, the duration of a second would vary if calibrated to a telescope-based standard like GMT or UT—in which a second was defined as a fraction of a day or year. The terms "GMT" and "Greenwich Mean Time" are sometimes used informally to refer to UT or UTC.
Question: Which standard of time started with British Railways?

Output:
Greenwich Mean Time
