Input: Frederic Chopin
In 1841, Leon Escudier wrote of a recital given by Chopin that year, "One may say that Chopin is the creator of a school of piano and a school of composition. In truth, nothing equals the lightness, the sweetness with which the composer preludes on the piano; moreover nothing may be compared to his works full of originality, distinction and grace." Chopin refused to conform to a standard method of playing and believed that there was no set technique for playing well. His style was based extensively on his use of very independent finger technique. In his Projet de methode he wrote: "Everything is a matter of knowing good fingering ... we need no less to use the rest of the hand, the wrist, the forearm and the upper arm." He further stated: "One needs only to study a certain position of the hand in relation to the keys to obtain with ease the most beautiful quality of sound, to know how to play short notes and long notes, and [to attain] unlimited dexterity." The consequences of this approach to technique in Chopin's music include the frequent use of the entire range of the keyboard, passages in double octaves and other chord groupings, swiftly repeated notes, the use of grace notes, and the use of contrasting rhythms (four against three, for example) between the hands.

What was Chopin's style based upon?
Output: independent finger technique

Input: Universal Studios
Burdened with debt, in 2004 Vivendi Universal sold 80% of Vivendi Universal Entertainment (including the studio and theme parks) to General Electric, parent of NBC. The resulting media super-conglomerate was renamed NBCUniversal, while Universal Studios Inc. remained the name of the production subsidiary. After that deal, GE owned 80% of NBC Universal; Vivendi held the remaining 20%, with an option to sell its share in 2006. GE purchased Vivendi's share in NBCU in 2011 and in turn sold 51% of the company to cable provider Comcast. Comcast merged the former GE subsidiary with its own cable-television programming assets, creating the current NBCUniversal. Following Federal Communications Commission (FCC) approval, the Comcast-GE deal was closed on Jan 29, 2011. In March 2013, Comcast bought the remaining 49% of NBCUniversal for $16.7 billion.

In what month and year did Comcast buy 49% of NBCUniversal?
Output: March 2013

Input: Greece
According to Greek law, every Sunday of the year is a public holiday. In addition, there are four mandatory official public holidays: 25 March (Greek Independence Day), Easter Monday, 15 August (Assumption or Dormition of the Holy Virgin), and 25 December (Christmas). 1 May (Labour Day) and 28 October (Ohi Day) are regulated by law as being optional but it is customary for employees to be given the day off. There are, however, more public holidays celebrated in Greece than are announced by the Ministry of Labour each year as either obligatory or optional. The list of these non-fixed national holidays rarely changes and has not changed in recent decades, giving a total of eleven national holidays each year.

How many official Greek mandatory public holidays are there?
Output: four

Input: Korean War
The initial assault by North Korean KPA forces were aided by the use of Soviet T-34-85 tanks. A North Korean tank corps equipped with about 120 T-34s spearheaded the invasion. These drove against a ROK Army with few anti-tank weapons adequate to deal with the Soviet T-34s. Additional Soviet armor was added as the offensive progressed. The North Korean tanks had a good deal of early successes against South Korean infantry, elements of the 24th Infantry Division, and those United States built M24 Chaffee light tanks that they encountered. Interdiction by ground attack aircraft was the only means of slowing the advancing Korean armor. The tide turned in favour of the United Nations forces in August 1950 when the North Koreans suffered major tank losses during a series of battles in which the UN forces brought heavier equipment to bear, including M4A3 Sherman medium tanks backed by U.S. M26 heavy tanks, along with the British Centurion, Churchill, and Cromwell tanks.

What form of attack was an effective measure of slowing Korean armor?
Output:
ground attack aircraft
