Input: Read this: The city of Nanjing was razed after the Sui dynasty took over it. It renamed Shengzhou (昇州) in Tang dynasty and resuscitated during the late Tang. It was chosen as the capital and called Jinling (金陵) during the Southern Tang (937–976), a state that succeeded Wu state. It renamed Jiangning (江寧) in Northern Song dynasty and renamed Jiankang in Southern Song dynasty. Jiankang's textile industry burgeoned and thrived during the Song dynasty despite the constant threat of foreign invasions from the north by the Jurchen-led Jin dynasty. The court of Da Chu, a short-lived puppet state established by the Jurchens, and the court of Song were once in the city. Song was eventually exterminated by the Mongol empire under the name Yuan and in Yuan dynasty the city's status as a hub of the textile industry was further consolidated.
Question: During what dynasty did Nanjing become a thriving textile city?

Output: the Song dynasty


Input: Read this: A central teaching of Jehovah's Witnesses is that the current world era, or "system of things", entered the "last days" in 1914 and faces imminent destruction through intervention by God and Jesus Christ, leading to deliverance for those who worship God acceptably. They consider all other present-day religions to be false, identifying them with "Babylon the Great", or the "harlot", of Revelation 17, and believe that they will soon be destroyed by the United Nations, which they believe is represented in scripture by the scarlet-colored wild beast of Revelation chapter 17. This development will mark the beginning of the "great tribulation". Satan will subsequently attack Jehovah's Witnesses, an action that will prompt God to begin the war of Armageddon, during which all forms of government and all people not counted as Christ's "sheep", or true followers, will be destroyed. After Armageddon, God will extend his heavenly kingdom to include earth, which will be transformed into a paradise similar to the Garden of Eden. After Armageddon, most of those who had died before God's intervention will gradually be resurrected during "judgment day" lasting for one thousand years. This judgment will be based on their actions after resurrection rather than past deeds. At the end of the thousand years, Christ will hand all authority back to God. Then a final test will take place when Satan is released to mislead perfect mankind. Those who fail will be destroyed, along with Satan and his demons. The end result will be a fully tested, glorified human race.
Question: How many demons will Satan be leading?

Output: unanswerable


Input: Read this: During Victoria's first pregnancy in 1840, in the first few months of the marriage, 18-year-old Edward Oxford attempted to assassinate her while she was riding in a carriage with Prince Albert on her way to visit her mother. Oxford fired twice, but either both bullets missed or, as he later claimed, the guns had no shot. He was tried for high treason and found guilty, but was acquitted on the grounds of insanity. In the immediate aftermath of the attack, Victoria's popularity soared, mitigating residual discontent over the Hastings affair and the bedchamber crisis. Her daughter, also named Victoria, was born on 21 November 1840. The Queen hated being pregnant, viewed breast-feeding with disgust, and thought newborn babies were ugly. Nevertheless, over the following seventeen years, she and Albert had a further eight children: Albert Edward, Prince of Wales (b. 1841), Alice (b. 1843), Alfred (b. 1844), Helena (b. 1846), Louise (b. 1848), Arthur (b. 1850), Leopold (b. 1853) and Beatrice (b. 1857).
Question: How old was Edward Oxford?

Output: 18


Input: Read this: Roughly one quarter of all zinc output in the United States (2009), is consumed in the form of zinc compounds; a variety of which are used industrially. Zinc oxide is widely used as a white pigment in paints, and as a catalyst in the manufacture of rubber. It is also used as a heat disperser for the rubber and acts to protect its polymers from ultraviolet radiation (the same UV protection is conferred to plastics containing zinc oxide). The semiconductor properties of zinc oxide make it useful in varistors and photocopying products. The zinc zinc-oxide cycle is a two step thermochemical process based on zinc and zinc oxide for hydrogen production.
Question: What kind of process is the zinc zinc-oxide cycle?

Output:
thermochemical
