Input: Read this: Greenware ceramics made from celadon had been made in the area since the 3rd-century Jin dynasty, but it returned to prominence—particularly in Longquan—during the Southern Song and Yuan. Longquan greenware is characterized by a thick unctuous glaze of a particular bluish-green tint over an otherwise undecorated light-grey porcellaneous body that is delicately potted. Yuan Longquan celadons feature a thinner, greener glaze on increasingly large vessels with decoration and shapes derived from Middle Eastern ceramic and metalwares. These were produced in large quantities for the Chinese export trade to Southeast Asia, the Middle East, and (during the Ming) Europe. By the Ming, however, production was notably deficient in quality. It is in this period that the Longquan kilns declined, to be eventually replaced in popularity and ceramic production by the kilns of Jingdezhen in Jiangxi.
Question:  What period did Longquan ceramics rise?

Output: unanswerable


Input: Read this: With the introduction of the blast furnace to Europe in the Middle Ages, pig iron was able to be produced in much higher volumes than wrought iron. Because pig iron could be melted, people began to develop processes of reducing the carbon in the liquid pig iron to create steel. Puddling was introduced during the 1700s, where molten pig iron was stirred while exposed to the air, to remove the carbon by oxidation. In 1858, Sir Henry Bessemer developed a process of steel-making by blowing hot air through liquid pig iron to reduce the carbon content. The Bessemer process was able to produce the first large scale manufacture of steel. Once the Bessemer process began to gain widespread use, other alloys of steel began to follow. Mangalloy, an alloy of steel and manganese exhibiting extreme hardness and toughness, was one of the first alloy steels, and was created by Robert Hadfield in 1882.
Question: When was the Bessemer process developed?

Output: 1858


Input: Read this: In 1863, the newly founded Football Association (the FA) published the Laws of the Game of Association Football, unifying the various different rules in use before then. On 20 July 1871, in the offices of The Sportsman newspaper, the FA Secretary C. W. Alcock proposed to the FA committee that "it is desirable that a Challenge Cup should be established in connection with the Association for which all clubs belonging to the Association should be invited to compete". The inaugural FA Cup tournament kicked off in November 1871. After thirteen games in all, Wanderers were crowned the winners in the final, on 16 March 1872. Wanderers retained the trophy the following year. The modern cup was beginning to be established by the 1888–89 season, when qualifying rounds were introduced.
Question: Who was the FA secretary in 1871?

Output: C. W. Alcock


Input: Read this: According to the tradition, Virgil traveled to Greece in about 19 BC to revise the Aeneid. After meeting Augustus in Athens and deciding to return home, Virgil caught a fever while visiting a town near Megara. After crossing to Italy by ship, weakened with disease, Virgil died in Brundisium harbor on September 21, 19 BC. Augustus ordered Virgil's literary executors, Lucius Varius Rufus and Plotius Tucca, to disregard Virgil's own wish that the poem be burned, instead ordering it published with as few editorial changes as possible. As a result, the text of the Aeneid that exists may contain faults which Virgil was planning to correct before publication. However, the only obvious imperfections are a few lines of verse that are metrically unfinished (i.e. not a complete line of dactylic hexameter). Some scholars have argued that Virgil deliberately left these metrically incomplete lines for dramatic effect. Other alleged imperfections are subject to scholarly debate.
Question: Where did Augustus die?
