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: How many days after JOhannes von Baysen was named the first governor of Prussia had most of the Prussian estates, aside from the Prince-Bishopric of Warmia, pleged allegiance to their new ruler?

A: number

Q: Passage: In 1343 Robert I the Sage, King of Naples, died. His only son, Charles of Calabria, had died in 1328, leaving two daughters, one of which, Joan, had been married to Andrew, son of king Charles I of Hungary. During his time in Naples, Andrew's more refined wife developed a fierce hostility towards him. After her father's death, she received from the Avignonese Pope Clement VI the official investment of the Kingdom, which was then nominally a vassal of the Papal States. Andrew, who also sought the crown, received only the title of Duke of Calabria. On June 14, 1345 Clement, after a payment of 44,000 marks, agreed to yield to Andrew the title of king, but only as heir in case of Joan's death. Joan, who was suspecred of having an affair with Louis of Taranto, was at the time under the strong influence of the latter's mother, Catherine of Valois. On September 19, the day before the investiture of Andrew as King, a conjure led by Catherine's relatives and courtesans had Andrew assassinated during a hunt at Aversa. Bertramo del Balzo, together with Fra Moriale, from the Hospitallers, discovered and punished the assassins, but suspicion of the queen's involvement in the assassination had already become widespread. In May 1346 Andrew's brother, King Louis of Hungary, sent envoys to Clement to ask for her deposition. Unsatisfied by the Pope's reply, he mustered an army, planning to embark his troops in Zara. However, at the time the maritime city had rebelled against the Venetians, whose ships were blockading its port. After a failed attempt to free it, the King had to postpone his expedition, while Zara returned under Venice's aegis.
Question: when did the father of Joan die?

Q: Passage: In South America , the Portuguese conquered from Spain most of the Rio Negro valley, and repelled a Spanish attack on Mato Grosso . Between September 1762 and April 1763, Spanish forces led by don Pedro Antonio de Cevallos, Governor of Buenos Aires  undertook a campaign against the Portuguese in Uruguay and South Brazil. The Spaniards conquered the Portuguese territories of Colonia do Sacramento and Rio Grande de São Pedro and forced the Portuguese to surrender and retreat. Under the Treaty of Paris , Spain had to return to Portugal the colony of Sacramento, while the vast and rich territory of the so-called "Continent of S. Peter"  would be retaken from the Spanish army during the undeclared Hispano-Portuguese war of 1763-1777. As consequence of the war the Valdivian Fort System, a Spanish defensive complex in southern Chile, was updated and reinforced from 1764 onwards. Other vulnerable localities of colonial Chile such as Chiloé Archipelago, Concepción, Juan Fernández Islands and Valparaíso were also made ready for an eventual English attack.
