Input: Planck constant
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.

What term describes a small amount of element?
Output: quantum

Input: Protestantism
A Protestant baptism is held to be valid by the Catholic Church if given with the trinitarian formula and with the intent to baptize. However, as the ordination of Protestant ministers is not recognized due to the lack of apostolic succession and the disunity from Catholic Church, all other sacraments (except marriage) performed by Protestant denominations and ministers are not recognized as valid. Therefore, Protestants desiring full communion with the Catholic Church are not re-baptized (although they are confirmed) and Protestant ministers who become Catholics may be ordained to the priesthood after a period of study.

What is the only other sacrament of the Protestants that the Catholic Church recognizes?
Output: marriage

Input: Crimean War
Peace negotiations at the Congress of Paris resulted in the signing of the Treaty of Paris on 30 March 1856. In compliance with article III, Russia restored to the Ottoman Empire the city and citadel of Kars in common with "all other parts of the Ottoman territory of which the Russian troop were in possession". Russia ceded some land in Bessarabia at the mouth of the Danube to Moldavia. By article IV The United Kingdom, France, Sardinia and Turkey restored to Russia "the towns and ports of Sevastopol, Balaklava, Kamish, Eupatoria, Kerch, Jenikale, Kinburn, as well as all other territories occupied by the allied troops". In conformity with article XI and XIII, the Tsar and the Sultan agreed not to establish any naval or military arsenal on the Black Sea coast. The Black Sea clauses weakened Russia, and it no longer posed a naval threat to the Ottomans. The principalities of Moldavia and Wallachia were nominally returned to the Ottoman Empire; in practice they became independent. The Great Powers pledged to respect the independence and territorial integrity of the Ottoman Empire.:432–33

What year was the Treaty of Paris signed?
Output: 1856

Input: Zhejiang
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.

What were greenware ceramics made from?
Output:
celadon
