Input: Article: Based on earlier research work by Loyd Ancile Jones (1884–1954) of Kodak and inspired by the systems of Weston film speed ratings and General Electric film values, the American Standards Association (now named ANSI) defined a new method to determine and specify film speeds of black-and-white negative films in 1943. ASA Z38.2.1-1943 was revised in 1946 and 1947 before the standard grew into ASA PH2.5-1954. Originally, ASA values were frequently referred to as American standard speed numbers or ASA exposure-index numbers. (See also: Exposure Index (EI).)

Now answer this question: When did the ANSI define its new measure?

Output: 1943

Input: Article: Around 1300–1350 the Medieval Warm Period gave way to the Little Ice Age. The colder climate resulted in agricultural crises, the first of which is known as the Great Famine of 1315-1317. The demographic consequences of this famine, however, were not as severe as the plagues that occurred later in the century, particularly the Black Death. Estimates of the death rate caused by this epidemic range from one third to as much as sixty percent. By around 1420, the accumulated effect of recurring plagues and famines had reduced the population of Europe to perhaps no more than a third of what it was a century earlier. The effects of natural disasters were exacerbated by armed conflicts; this was particularly the case in France during the Hundred Years' War.

Now answer this question: Which climactic epoch followed the Medieval Warm Period?

Output: the Little Ice Age

Input: Article: Marsha Weidner states that Deshin Shekpa's miracles "testified to the power of both the emperor and his guru and served as a legitimizing tool for the emperor's problematic succession to the throne," referring to the Yongle Emperor's conflict with the previous Jianwen Emperor. Tsai writes that Deshin Shekpa aided the legitimacy of the Yongle Emperor's rule by providing him with portents and omens which demonstrated Heaven's favor of the Yongle Emperor on the Ming throne.

Output:
Deshin Shekpa
