Input: Read this: At the 1966 "Man the Hunter" conference, anthropologists Richard Borshay Lee and Irven DeVore suggested that egalitarianism was one of several central characteristics of nomadic hunting and gathering societies because mobility requires minimization of material possessions throughout a population. Therefore, no surplus of resources can be accumulated by any single member. Other characteristics Lee and DeVore proposed were flux in territorial boundaries as well as in demographic composition.
Question: When was the Man the Hunter conference?

Output: 1966

Input: Read this: Sir John Call argued the advantages of Norfolk Island in that it was uninhabited and that New Zealand flax grew there. In 1786 the British government included Norfolk Island as an auxiliary settlement, as proposed by John Call, in its plan for colonisation of New South Wales. The decision to settle Norfolk Island was taken due to Empress Catherine II of Russia's decision to restrict sales of hemp. Practically all the hemp and flax required by the Royal Navy for cordage and sailcloth was imported from Russia.
Question: What year did the German government include Norfolk Island as a auxiliary settlement?

Output: unanswerable

Input: Read this: Most historical accounts state that the island was discovered on 21 May 1502 by the Galician navigator Joao da Nova sailing at the service of Portugal, and that he named it "Santa Helena" after Helena of Constantinople. Another theory holds that the island found by da Nova was actually Tristan da Cunha, 2,430 kilometres (1,510 mi) to the south, and that Saint Helena was discovered by some of the ships attached to the squadron of Estevao da Gama expedition on 30 July 1503 (as reported in the account of clerk Thome Lopes). However, a paper published in 2015 reviewed the discovery date and dismissed the 18 August as too late for da Nova to make a discovery and then return to Lisbon by 11 September 1502, whether he sailed from St Helena or Tristan da Cunha. It demonstrates the 21 May is probably a Protestant rather than Catholic or Orthodox feast-day, first quoted in 1596 by Jan Huyghen van Linschoten, who was probably mistaken because the island was discovered several decades before the Reformation and start of Protestantism. The alternative discovery date of 3 May, the Catholic feast-day for the finding of the True Cross by Saint Helena in Jerusalem, quoted by Odoardo Duarte Lopes and Sir Thomas Herbert is suggested as being historically more credible.
Question: What date was the island discovered on?

Output: 21 May 1502

Input: Read this: The Alps provide lowland Europe with drinking water, irrigation, and hydroelectric power. Although the area is only about 11 percent of the surface area of Europe, the Alps provide up to 90 percent of water to lowland Europe, particularly to arid areas and during the summer months. Cities such as Milan depend on 80 percent of water from Alpine runoff. Water from the rivers is used in over 500 hydroelectricity power plants, generating as much as 2900 kilowatts of electricity.
Question: How much water does the Alps provide to lowland Europe?

Output:
90 percent
