TASK DEFINITION: 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.
PROBLEM: Passage: With the tribes to the north and west destroyed, the Iroquois turned their attention southward to the Iroquoian-speaking Susquehannock. 1660 marked the zenith of Iroquois military power, and they were able to use that to their advantage in the decades to follow. The Susquehannock had become allied with the English in the Maryland colony in 1661. The English had grown fearful of the Iroquois and hoped an alliance with Susquehannock would help block the northern tribes' advance on the English colonies. In 1663 the Iroquois sent an army of 800 warriors into the Susquehannock territory. They repulsed the army, but the invasion prompted the colony of Maryland to declare war on the Iroquois. By supplying Susquehannock forts with artillery, the English in Maryland changed the balance of power away from the Iroquois. The Susquehannock took the upper hand and began to invade Iroquois territory, where they caused significant damage. This warfare continued intermittently for 11 years. In 1674 the English in Maryland changed their Indian Policy and negotiated peace with the Iroquois. They terminated their alliance with the Susquehannock. In 1675 the militias of Virginia and Maryland captured and executed the chiefs of the Susquehannock, whose growing power they feared. The Iroquois made quick work of the rest of the nation. They drove the warriors from traditional territory and absorbed the survivors in 1677. During the course of this conflict, in 1670 the Iroquois also drove the Siouan-speaking Mannahoac tribe out of the northern Virginia Piedmont region. The Iroquois claimed the land by right of conquest as a hunting ground. The English acknowledged this claim in 1674 and again in 1684. They acquired the land from the Iroquois by a 1722 treaty.
Question: How many years after the Iroquois military power reached its zenith, did the militias of Virginia and Maryland execute the chiefs of the Susquehannock?

SOLUTION: number

PROBLEM: Passage: The late 17th century was a difficult period for Scotland, as it was for much of Europe; the years 1695-97 saw catastrophic famine in present-day Estonia, Finland, Latvia, Norway and Sweden plus an estimated two million deaths in France and Northern Italy.  Scotland's economy was relatively small, its range of exports very limited and it was in a weak position in relation to England, its powerful neighbour . In an era of economic rivalry in Europe, Scotland was incapable of protecting itself from the effects of English competition and legislation. The kingdom had no reciprocal export trade and its once thriving industries such as shipbuilding were in deep decline; goods that were in demand had to be bought from England for sterling. Moreover, the Navigation Acts further increased economic dependence on England by limiting Scotland's shipping, and the Royal Scots Navy was relatively small. A series of domestic conflicts, including the 1639-51 Wars of the Three Kingdoms and unrest related to religious differences between 1670-1690 exhausted the people and diminished their resources. The so-called "seven ill years" of the 1690s saw widespread crop failures and famine, while Scotland's deteriorating economic position led to calls for a political or customs union with England. However, the stronger feeling among Scots was that the country should become a great mercantile and colonial power like England. In response a number of solutions were enacted by the Parliament of Scotland: in 1695the Bank of Scotland was established; the Act for the Settling of Schools created a parish-based system of public education throughout Scotland; and the Company of Scotland was chartered with capital to be raised by public subscription to trade with "Africa and the Indies".
Question: When did the Wars of the Three Kingdoms end?
