Input: Read this: The beginning of the 20th century brought the start of a revolution in physics. The long-held theories of Newton were shown not to be correct in all circumstances. Beginning in 1900, Max Planck, Albert Einstein, Niels Bohr and others developed quantum theories to explain various anomalous experimental results, by introducing discrete energy levels. Not only did quantum mechanics show that the laws of motion did not hold on small scales, but even more disturbingly, the theory of general relativity, proposed by Einstein in 1915, showed that the fixed background of spacetime, on which both Newtonian mechanics and special relativity depended, could not exist. In 1925, Werner Heisenberg and Erwin Schrödinger formulated quantum mechanics, which explained the preceding quantum theories. The observation by Edwin Hubble in 1929 that the speed at which galaxies recede positively correlates with their distance, led to the understanding that the universe is expanding, and the formulation of the Big Bang theory by Georges Lemaître.
Question: What year did Einstein discover the theory of general relativity?

Output: 1915


Input: Read this: VRS services have become well developed nationally in Sweden since 1997 and also in the United States since the first decade of the 2000s. With the exception of Sweden, VRS has been provided in Europe for only a few years since the mid-2000s, and as of 2010 has not been made available in many European Union countries, with most European countries still lacking the legislation or the financing for large-scale VRS services, and to provide the necessary telecommunication equipment to deaf users. Germany and the Nordic countries are among the other leaders in Europe, while the United States is another world leader in the provisioning of VRS services.
Question: What country is a world leader in providing VRS services?

Output: United States


Input: Read this: Olin has a network of more than 16,000 alumni worldwide. Over the last several years, the school’s endowment has increased to $213 million (2004) and annual gifts average $12 million per year.[citation needed] Simon Hall was opened in 1986 after a donation from John E. Simon. On May 2, 2014, the $90 million conjoined Knight and Bauer Halls were dedicated, following a $15 million gift from Charles F. Knight and Joanne Knight and a $10 million gift from George and Carol Bauer through the Bauer Foundation.
Question: How much did Simon Hall cost to build?

Output: unanswerable


Input: Read this: There has been an increasing gulf between the Premier League and the Football League. Since its split with the Football League, many established clubs in the Premier League have managed to distance themselves from their counterparts in lower leagues. Owing in large part to the disparity in revenue from television rights between the leagues, many newly promoted teams have found it difficult to avoid relegation in their first season in the Premier League. In every season except 2001–02 and 2011–12, at least one Premier League newcomer has been relegated back to the Football League. In 1997–98 all three promoted clubs were relegated at the end of the season.
Question: Due to the disparity in television rights revenue between leagues, who struggles to avoid relegation in their Premier League first season?

Output:
newly promoted teams
