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 Krakow 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: According to the 2010 United States Census, the City and County of Denver contained 600,158 people and 285,797 households. The population density was 3,698 inhabitants per square mile (1,428/km) including the airport. There were 285,797 housing units at an average density of 1,751 per square mile (676/km). However, the average density throughout most Denver neighborhoods tends to be higher. Without the 80249 zip code (47.3 sq mi, 8,407 residents) near the airport, the average density increases to around 5,470 per square mile.Age distribution was 22.0% under the age of 18, 10.7% from 18 to 24, 36.1% from 25 to 44, 20.0% from 45 to 64, and 11.3% who were 65 years of age or older. The median age is 33 years. Overall there were 102.1 males for every 100 females, but in 2015 for the category of never-married ages 25 to 34, there were 121.4 males for every 100 females. Due to a skewed sex ratio wherein single men outnumber single women, some protologists have nicknamed the city as Menver.
Question: Which age group populated Denver less, those under the age of 18 or 18 to 44?
[A]: span

[Q]: Passage: On 22 December the Pretender landed in Scotland at Peterhead, but by the time he arrived at Perth on 9 January 1716, the Jacobite army numbered fewer than 5,000. In contrast, Argyll's forces had acquired heavy artillery and were advancing quickly. Mar decided to burn a number of villages between Perth and Stirling, so as to deprive Argyll's army of supplies. On 30 January Mar led the Jacobites out of Perth; on 4 February the Pretender wrote a farewell letter to Scotland, sailing from Montrose the following day. Many Jacobites who were taken prisoner were tried for treason and sentenced to death. The Indemnity Act of July 1717 pardoned all those who had taken part in the Rising, but the whole of the Clan Gregor, including Rob Roy MacGregor, was specifically excluded from the benefits of that Act. Another attempt, this time with Spanish support, was undertaken in 1719, only to end again in defeat in the Battle of Glenshiel. James's son Charles Edward Stuart attempted to win the throne for his father in 1745, in another Jacobite rising, but was defeated at the Battle of Culloden. James died in 1766.
Question: What date did the Pretender sail from Montrose?
[A]:
date
