Problem: As is sometimes common in scientific discoveries, simultaneous developments can occur, as evidenced by a number of inventors who were at work on the telephone. Over a period of 18 years, the Bell Telephone Company faced 587 court challenges to its patents, including five that went to the U.S. Supreme Court, but none was successful in establishing priority over the original Bell patent and the Bell Telephone Company never lost a case that had proceeded to a final trial stage. Bell's laboratory notes and family letters were the key to establishing a long lineage to his experiments. The Bell company lawyers successfully fought off myriad lawsuits generated initially around the challenges by Elisha Gray and Amos Dolbear. In personal correspondence to Bell, both Gray and Dolbear had acknowledged his prior work, which considerably weakened their later claims.
How many times were Bell's patents contested?
The answer is the following: 587

Problem: The main party leaders, David Cameron, Nick Clegg and Ed Miliband, were all depicted holding a copy of the special issue in publicity material. Miliband's decision to pose with a copy of The Sun received a strong response. Organisations representing the relatives of Hillsborough victims described Miliband's action as an "absolute disgrace" and he faced criticism too from Liverpool Labour MPs and the city's Labour Mayor, Joe Anderson. A statement was issued on 13 June explaining that Miliband "was promoting England's bid to win the World Cup", although "he understands the anger that is felt towards the Sun over Hillsborough by many people in Merseyside and he is sorry to those who feel offended."
Who was the Labour Mayour of Liverpool?
The answer is the following: Joe Anderson

Problem: First recognized in 1900 by Max Planck, it was originally the proportionality constant between the minimal increment of energy, E, of a hypothetical electrically charged oscillator in a cavity that contained black body radiation, and the frequency, f, of its associated electromagnetic wave. In 1905 the value E, the minimal energy increment of a hypothetical oscillator, was theoretically associated by Einstein with a "quantum" or minimal element of the energy of the electromagnetic wave itself. The light quantum behaved in some respects as an electrically neutral particle, as opposed to an electromagnetic wave. It was eventually called the photon.
Who discovered an association between the value E and quantum energy?
The answer is the following: Einstein

Problem: From 1792, when the Mint Act was passed, the dollar was defined as 371.25 grains (24.056 g) of silver. Many historians[who?] erroneously assume gold was standardized at a fixed rate in parity with silver; however, there is no evidence of Congress making this law. This has to do with Alexander Hamilton's suggestion to Congress of a fixed 15:1 ratio of silver to gold, respectively. The gold coins that were minted however, were not given any denomination whatsoever and traded for a market value relative to the Congressional standard of the silver dollar. 1834 saw a shift in the gold standard to 23.2 grains (1.50 g), followed by a slight adjustment to 23.22 grains (1.505 g) in 1837 (16:1 ratio).[citation needed]
Who suggested that the ratio of silver to gold should be fixed?
The answer is the following:
Alexander Hamilton
