Problem: Prior to Planck's work, it had been assumed that the energy of a body could take on any value whatsoever – that it was a continuous variable. The Rayleigh–Jeans law makes close predictions for a narrow range of values at one limit of temperatures, but the results diverge more and more strongly as temperatures increase. To make Planck's law, which correctly predicts blackbody emissions, it was necessary to multiply the classical expression by a complex factor that involves h in both the numerator and the denominator. The influence of h in this complex factor would not disappear if it were set to zero or to any other value. Making an equation out of Planck's law that would reproduce the Rayleigh–Jeans law could not be done by changing the values of h, of the Boltzmann constant, or of any other constant or variable in the equation. In this case the picture given by classical physics is not duplicated by a range of results in the quantum picture.
What does Planck's law correctly predict?
The answer is the following: blackbody emissions


In the 1772 First Partition of Poland, the Prussian king Frederick the Great annexed neighboring Royal Prussia, i.e. the Polish voivodeships of Pomerania (Gdańsk Pomerania or Pomerelia), Malbork, Chełmno and the Prince-Bishopric of Warmia, thereby bridging the "Polish Corridor" between his Prussian and Farther Pomeranian lands and cutting remaining Poland off the Baltic Coast. The territory of Warmia was incorporated into the lands of former Ducal Prussia, which, by administrative deed of 31 January 1773 were named East Prussia. The former Polish Pomerelian lands beyond the Vistula River together with Malbork and Chełmno Land formed the Province of West Prussia with its capital at Marienwerder (Kwidzyn). The Polish Partition Sejm ratified the cession on 30 September 1773, whereafter Frederick officially went on to call himself a King "of" Prussia.
What was ratified in 1773 in Prussia?
The Polish Partition Sejm


Input: Chihuahua (state)
The liberal political forces maintained strong control over the state government until shortly after the French Intervention which turned the tables in favor to the conservative forces once again. The intervention had serious repercussions for the state of Chihuahua. President Juárez, in an effort to organize a strong defense against the French, decreed a list of national guard units that every state had to contribute to the Ministry of War and the Navy; Chihuahua was responsible for inducting 2,000 men. Regaining power, Governor Luis Terrazas assigned the First Battalion of Chihuahua for integration into the national army led by General Jesús González Ortega; the battalion was deployed to Puebla. After the defeat of the army in Puebla, the Juárez administration was forced to abandon Mexico City; the president retreated further north seeking refuge in the state of Chihuahua.

Which political forces maintained strong control over the state until shortly after French intervention?
Output: liberal


Input: Article: Ibn Sina (Avicenna) is regarded as the most influential philosopher of Islam. He pioneered the science of experimental medicine and was the first physician to conduct clinical trials. His two most notable works in medicine are the Kitāb al-shifāʾ ("Book of Healing") and The Canon of Medicine, both of which were used as standard medicinal texts in both the Muslim world and in Europe well into the 17th century. Amongst his many contributions are the discovery of the contagious nature of infectious diseases, and the introduction of clinical pharmacology.

Now answer this question: What does Kitab al-shifa mean?

Output: Book of Healing


Article: In Article 3 of the Treaty of San Francisco between the Allied Powers and Japan, which came into force in April 1952, the U.S. put the outlying islands of the Ryukyus, including the island of Okinawa—home to over 1 million Okinawans related to the Japanese—and the Bonin Islands, the Volcano Islands, and Iwo Jima into U.S. trusteeship. All these trusteeships were slowly returned to Japanese rule. Okinawa was returned on May 15, 1972, but the U.S. stations troops in the island's bases as a defense for Japan.

Question: When was Okinawa finally returned?
Ans: May 15, 1972


Input: Greeks
The evolution of Proto-Greek should be considered within the context of an early Paleo-Balkan sprachbund that makes it difficult to delineate exact boundaries between individual languages. The characteristically Greek representation of word-initial laryngeals by prothetic vowels is shared, for one, by the Armenian language, which also seems to share some other phonological and morphological peculiarities of Greek; this has led some linguists to propose a hypothetical closer relationship between Greek and Armenian, although evidence remains scant.

What other language has this same trait ?
Output:
word-initial laryngeals by prothetic vowels is shared, for one, by the Armenian language
