This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.

[Q]: Passage: In January 1454, the year that Casimir IV was married to Elisabeth Habsburg, the Prussian faction asked Casimir IV and protection by the Kingdom of Poland. Casimir asked the Prussian Confederation for a more formal petition. On 4 February 1454, the Secret Council of the Prussian Confederation sent a formal act of disobedience to the Grand Master. Two days later the confederacy started its rebellion and soon almost all Prussia, except for Marienburg, Stuhm , and Konitz , were free from Teutonic rule. Most of the captured Ordensburg castles were immediately destroyed. On 10 February 1454, the confederacy sent an official delegation to Poland, headed by Johannes von Baysen. By 20 February, the delegates were in Kraków and asked Casimir to bring Prussia into the Polish kingdom. After negotiating the exact conditions of incorporation, the king agreed and delegates of the Prussian Confederation pledged allegiance to Casimir on 6 March 1454. On the same day, the king agreed to all the conditions of the Prussian delegates — for instance Thorn demanded the destruction of the Polish city of Nieszawa — giving wide privileges to the Prussian cities and nobility. Three days later, Johannes von Baysen was named as the first governor of Prussia. After 15 April, most of the Prussian estates, with the exception of the Prince-Bishopric of Warmia, pledged allegiance to their new ruler. Poland sent the Grand Master a declaration of war, predated to 22 February. Both sides expected the war to end quickly.
Question: When did the confederacy start its rebellion?

[Q]: Passage: ESB, Ervia and Airtricity are the three main electricity and gas suppliers in Ireland. There are 19.82 billion cubic metres of proven reserves of gas. Natural gas extraction previously occurred at the Kinsale Head until its exhaustion. The Corrib gas field was due to come on stream in 2013/14. In 2012, the Barryroe field was confirmed to have up to 1.6 billion barrels of oil in reserve, with between 160 and 600 million recoverable. That could provide for Ireland's entire energy needs for up to 13 years, when it is developed in 2015/16. There have been significant efforts to increase the use of renewable and sustainable forms of energy in Ireland, particularly in wind power, with 3,000 MegaWatts of wind farms being constructed, some for the purpose of export. The Sustainable Energy Authority of Ireland  has estimated that 6.5% of Ireland's 2011 energy requirements were produced by renewable sources. The SEAI has also reported an increase in energy efficiency in Ireland with a 28% reduction in carbon emissions per house from 2005 to 2013.
Question: What natural gas site was depleted before the Corrib gas field was due to come on?
[A]: span


[Q]: Passage: Matthias and Frederick III/V had been rivals stretching back to Matthias' succession as King of Hungary in 1458 after the early death of Frederick's Habsburg cousin King Ladislaus the Posthumous. At this time, Frederick held the Holy Crown of Hungary and was a candidate for becoming Hungarian king himself. Matthias, backed by the Bohemian king George of Poděbrady whose daughter Catherine  he married in 1461, finally prevailed: the two rivals settled their disagreements in 1463 with the Treaty of Wiener Neustadt, in which Frederick recognized the de facto King of Hungary and returned the Holy Crown to Matthias for a heavy ransom. With the consent of Pope Paul II, Matthias invaded Moravia in 1468, instigating the Bohemian War with his former ally George of Poděbrad, on the pretext of protecting Catholicism against the Hussite movement - in fact to depose his father-in-law King George. Welcomed by the German nobility in Silesia and the Lusatias, as well as by the Catholic Czechs in Moravia, Matthias acquired these territories for himself and in 1469 pronounced himself Bohemian king in Olomouc. Never able to seize the capital Prague however, Matthias' war would drag on with Poděbrad's successor, the Polish prince Vladislaus Jagiellon, until the latter recognized Matthias' gains in the 1478 Treaty of Brno. Emperor Frederick, at the same time stuck in the France-Habsburg rivalry over the Burgundian succession with King Louis XI of France, had initially assisted Matthias against the Hussites in the Bohemian War. Contributing very little however, Frederick soon came to reverse his role and forged an alliance with Poděbrad's successor Vladislaus whom he enfeoffed with the Kingdom of Bohemia in 1477. Angered by this action and recalling previous insults, Matthias proceeded to press for a peace with Vladislaus and invaded Frederick's Austrian lands.
Question: What 1/10 of a decade did Matthias and Frederick III/V had been rivals?
