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.

Example Input: Passage: The site of the battle is located near U.S. Highway 56, about three miles east of Baldwin City, and is partially within Robert Hall Pearson Memorial Park, designated by the state of Kansas in honor of one of Brown and Shore's fighters who gave a handwritten account of the battle. Signs placed throughout the battle site point out where the battle began and ended. Efforts are underway to preserve both the Pearson Memorial Park and the Ivan Boyd Prairie Preserve across the road. In 1970, to commemorate the 100th anniversary of the founding of Baldwin City, Baker University professor and playwright Don Mueller and Phyllis E. Braun, Business Manager, produced a musical play entitled The Ballad Of Black Jack to tell the story of the events that led up to the battle. The Ballad Of Black Jack played as part of the city's Maple Leaf Festival from 1970-83 and again from 2001-05. It also played in nearby Lawrence in 1986 and in 2006 and 2007 as a part of Lawrence's Civil War On The Western Frontier program. In 2012 the National Park Service designated the battlefield a National Historic Landmark.
Question: When was the last time the Ballad of Black Jack was played as part of the city's Maple Leaf Festival?

Example Input: Passage: In the Treaty of Labiau on 20 November, Charles X Gustav of Sweden granted Frederick William of Brandenburg full sovereignty in the Duchy of Prussia in turn for a more active participation in the war. In the Treaty of Radnot on 6 December, Charles X Gustav promised to accept George II Rakoczi of Transylvania as king of Poland and Grand Duke of Lithuania in return for his entrance into the war. Rakoczi entered the war in January 1657, crossing into the commonwealth with a force of 25,000 Transylvanian-Wallachian-Moldavian men and 20,000 Cossacks who broke the Polish siege of Krakow before they met with Charles X Gustav, who had led a Swedish-Brandenburgian army southwards. The following month saw the Swedish-Brandenburg-Transylvanian-Romanian-Cossack forces play cat and mouse with the Polish-Lithuanian forces, moving about all of the commonwealth without any major engagements, except the capture of Brest by Charles X Gustav in May, and the sack of Warsaw by Rakoczi and Gustaf Otto Stenbock on 17 June. Due to internal conflicts within the Cossacks practically there was no participation of Cossack Hetmanate in that war. Worn out from previous campaigns and requesting Bohdan Khmelnytsky to break with Sweden, Alexis of Russia eventually signed the Truce of Vilna or Niemiez with the Polish-Lithuanian Commonwealth, and did not engage the Swedish army in any major battle throughout 1657 even though he still reinforced his armies in Livonia. On 18 June, a Swedish force defeated a Russian army of 8,000 men commanded by Matvey V. Sheremetev in the Battle of Walk at Walk . In early 1658, Sweden and Russia agreed on a truce, resulting in the Treaty of Valiesar and the Treaty of Kardis . The Russian war with Poland-Lithuania on the other hand resumed in 1658.
Question: What day was the Treaty of Labiau signed?

Example Input: Passage: While reliable figures are difficult to obtain, estimated global sales of The Hobbit run between 35 and 100 million copies since 1937. In the UK The Hobbit has not retreated from the top 5,000 books of Nielsen BookScan since 1995, when the index began, achieving a three-year sales peak rising from 33,084 (2000) to 142,541 (2001), 126,771 (2002) and 61,229 (2003), ranking it at the 3rd position in Nielsens "Evergreen" book list. The enduring popularity of The Hobbit makes early printings of the book attractive collectors items. The first printing of the first English-language edition can sell for between 6,000 and 20,000 at auction, although the price for a signed first edition has reached over 60,000.
Question: What year were the most copies of the Hobbit sold?
