PROBLEM: 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?

SOLUTION: date

PROBLEM: Passage: In April 1543 Suleiman launched another campaign in Hungary, bringing back Bran and other forts so that much of Hungary was under Ottoman control. As part of a Franco-Ottoman alliance , French troops were supplied to the Ottomans in Hungary: a French artillery unit was dispatched in 1543-1544 and attached to the Ottoman Army. In August 1543, the Ottoman succeeded in the Siege of Esztergom The siege would be followed by the capture of the Hungarian coronation city of Székesfehérvár in September 1543. Other cities that were captured during this campaign are Siklós and Szeged in order to better protect Buda. However, continuous delay of the push toward the west, because of the siege of these fortresses, meant that the Ottomans could not launch any new offensive against Austria. From 1548 to the end of the war, a Habsburg Spanish infantry tercio which had fought in the Schmalkaldic War, led by Maestre de campo Bernardo de Aldana, was detached in Hungary to fight against John Zápolya's supporters on behalf of Ferdinand. In fact, the Holy Roman Emperor Charles V sent Spanish troops to help his brother regularly from 1527 to 1553, a support that proved instrumental in Hungary remaining inside Christianity.
Question: What was former year that Charles V sent Spanish troops to help his brother?

SOLUTION: date

PROBLEM: Passage: A rejuvenated Nick Foles got his starting job back after being benched in favor of Case Keenum, who suffered a concussion after last week's loss in Baltimore. However, Foles' return was marred as he struggled to find open receivers and was picked off three times by the Bengals ranked defense. He also took hits throughout the game and he was sacked a few times. The only Rams score was a 5-yard run by Tavon Austin on a reverse play in the second quarter. St. Louis' defense was not a factor all game as they struggled to stop the high-powered Bengals offense led by quarterback Andy Dalton, and receivers A. J. Green, and Tyler Eifert, (the latter left the game with a stinger) who is leading the league in touchdown catches. With the loss, the Rams extended their losing streak to 4 games, making their record 4-7.
Question: Who did Keenum suffer his concussion playing against?

SOLUTION:
span
