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.

[EX Q]: Passage: With regulations in place and DDT banned, the eagle population rebounded. The bald eagle can be found in growing concentrations throughout the United States and Canada, particularly near large bodies of water. In the early 1980s, the estimated total population was 100,000 individuals, with 110,000–115,000 by 1992; the U.S. state with the largest resident population is Alaska, with about 40,000–50,000, with the next highest population the Provinces and territories of Canada of British Columbia with 20,000–30,000 in 1992. Obtaining a precise count of bald eagles population is extremely difficult. The most recent data submitted by individual states was in 2006, when 9789 breeding pairs were reported. For some time, the stronghold breeding population of bald eagles in the lower 48 states was in Florida, where over a thousand pairs have held on while populations in other states were significantly reduced by DDT use. Today, the Contiguous United States with the largest number of breeding pairs of eagles is Minnesota with an estimated 1,312 pairs, surpassing Floridas most recent count of 1,166 pairs. 23, or nearly half, of the 48 contiguous states now have at least 100 breeding pairs of bald eagles. In Washington State, there were only 105 occupied nests in 1980.  That number increased by about 30 per year, so that by 2005 there were 840 occupied nests. 2005 was the last year that the Washington Department of Fish and Wildlife counted occupied nests. Further population increases in Washington may be limited by the availability of late winter food, particularly salmon.
Question: Which area had the second highest numbers of bald eagles in 1992?
[EX A]: span

[EX Q]: Passage: In a game that saw the return of Alex Smith to the Bay Area, the Niners prevailed in a see-saw game, 22-17, on the strength of five Phil Dawson field goals. Kansas City took an early lead on a Smith to Travis Kelce touchdown pass, but Colin Kaepernick hit Stevie Johnson with a TD pass just before halftime for a 13-10 lead. Smith struck again in the third quarter with a 17-yard scoring pass to De'Anthony Thomas, but Dawson hit three more field goals to give the Niners the win. The Niners outgained the Chiefs 357-264, and had a 36:04-23:56 time of possession advantage, but they only scored one touchdown in four trips into the red zone, continuing their season-long problem in that area.
Question: How many less overall yards did the Chiefs have?
[EX A]: number

[EX Q]: Passage: The conflict is often referred to by different names, most commonly the Russo-Polish War, with the term Russia replacing the term Muscovy. In Polish historiography, the wars are usually referred to as the Dimitriads: the First Dymitriad  and Second Dymitriad  and the Polish-Muscovite War , which can subsequently be divided into two wars of 1609-1611 and 1617-1618, and may or may not include the 1617-1618 campaign, which is sometimes referred to as Chodkiewicz  Campaign. According to Russian historiography, the chaotic events of the war fall into the "Time of Troubles". The conflict with Poles is commonly called the Polish Invasion, Polish Intervention, or more specifically the Polish Intervention of the Early Seventeenth Century.
Question: How many years long was the longest war?
[EX A]:
number
