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.

Passage: The population of the Jews in Gorlice is not well documented or reliable before the later half of the 19th century.  There are statistics on the Jewish population from 1880 to 1910 though.  Looking first at the Gorlice district in 1880 there was a total of 74,072 residents and out of those 6.4% (4,755) were Jews.  Just in the city of Gorlice itself, there were 2,257 jews out of the around 5,000 residents of the city which is close to 50%.  The population of Jews in Gorlice grew to 7.5% of the Gorlice district composed of Jews in 1910 and 51% of residents in the City of Gorlice were Jewish at that time (3,495 out of 6,600).
Question: In what year was the Jewish population slightly less than 50%?
date

Passage: Frederick had been King of Jerusalem—and as such claimed suzerainty over Cyprus—in right of his wife Isabella II until her death in 1228. That year he arrived first in Cyprus, where he antagonised the nobles, and then in Jerusalem, where he stayed until 1229, leaving in humiliating circumstances after having produced an anti-imperialist reaction in the people. In 1231 he sent Riccardo Filangieri as his marshal. His attempt to assert his authority was opposed by John of Ibelin, the Old Lord of Beirut, who had been regent until Frederick's arrival. On John's death in 1236 the war was taken up by his son Balian. In 1239 Philip of Montfort assumed the leadership of the opposition. Though the ecclesiastical hierarchy and the Knights Templar supported the nobility, the Teutonic Knights and Knights Hospitaller supported Filangieri. In general his rights as regent were recognised but his practical power was denied on the basis of the Assizes and the Haute Cour. His headquarters were in Tyre and he had the allegiance of Bohemond V, Prince of Antioch and Count of Tripoli. He also held the Holy City of Jerusalem itself, which had been negotiated away from the Saracens by Frederick. So long as the Ibelins controlled the opposition, Filangieri could count on the support of their enemies as well. The Italian cities were also divided between the two factions: Pisa supported Filangieri and Genoa the Ibelins. The Ibelins controlled Beirut, Arsuf, and Caesarea as well as the old capital of Acre. In 1231 the citizens of Acre formed a commune with their headquarters at the church of Saint Andrew's in order to unify their opposition to Filangieri. In 1232 John of Ibelin was elected its mayor.
Question: How many years after the citizens of Acre formed a commune to unify their opposition to Filangieri was John of Ibelin elected its mayor?

Passage: Plymouth Colony lost close to eight percent of its adult male population and a smaller percentage of women and children to Indian warfare or other causes associated with the war.:332 Indian losses were much greater, with about 2,000 men killed or who died of injuries in the war, more than 3,000 dying of sickness or starvation, and another 1,000 Indians sold into slavery and transported to other areas, such as the British-controlled islands in the Caribbean. About 2,000 Indians escaped to other tribes to the north or west; they joined continued Indian attacks from those bases well into the next century. Historians estimate that, as a result of King Philip's War, the Indian population of southern New England was reduced by about 40 to 80 percent. The war escalated from a local conflict to involve most of southern New England and reached to other east coast areas as well. The war killed nearly as high a percentage of the Indian population as the plagues of 1616-19. It is estimated that the Indians of New England made up almost 30 percent of the total regional population, but the Indian population had dropped to less than 15 percent by 1680, five years after the war began.:345 The settlers incurred an enormous tax burden to pay for the war, which held back the economy of the entire region for many years.:346
Question: How many years passed that killed the Indians in plaques in 1616-1619?
