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: Švitrigaila was losing his influence in the Slavic principalities and could no longer resist Poland and Sigismund. On 4 September 1437 he attempted to reconcile with Poland: he would rule the lands that still backed him , and after his death these territories would pass to the King of Poland. However, under strong protest from Sigismund, the Polish Senate declined to ratify the treaty . In 1438 Švitrigaila withdrew to Moldavia. The reign of Sigismund Kęstutaitis was brief — he was assassinated in 1440. Švitrigaila returned from exile in 1442 and ruled Lutsk until his death a decade later. Jogaila's son Casimir IV Jagiellon, born in 1426, received approval as a hereditary hospodar from Lithuania's ruling families in 1440. This event is seen by the historians Jerzy Lukowski and Hubert Zawadzki as marking the end of the succession dispute.
Question: What year did Švitrigaila die?

SOLUTION: date

PROBLEM: Passage: In 1554 the Pechenga Monastery was raided by the Swedes. The governor of Novgorod Paletsky sent Nikita Kuzmin to Stockholm to ask for an explanation, but the Russian representative was imprisoned. In response Russia mounted an organized attack with up to 20,000 soldiers in March 1555. With its initially 1,000 men, Finland could not stand against the invading troops, but soon, reinforcements consisting of 3,700 infantrymen and 250 cavalrymen arrived from Sweden. The Finnish nobility had also been engaged in the war, contributing with its cavalry. The goal of the Swedish-Finnish troops was to conquer Oreshek, Korela and Koporye. The siege of Oreshek was badly planned by the Swedish side and failed since the Russians had destroyed the areas surrounding the town and the Swedish troops had insufficient supplies to be able to maintain the siege until the town surrendered. While admiral Johan Brigge besieged and bombarded Oreshek,  the Swedish diplomats tried to find support for their cause in Livonia, Poland-Lithuania and England. Early the following year, 1556, Russia made a new attack, this time with an army almost 20,000 men strong. The attack was aimed at the town of Viborg , and the Swedish troops were unlikely to withstand an army of that considerable size. However, after a few days of pillaging in the area around Viborg, the Russian forces left. The reason for this has not been made clear. Conceivable reasons might be bad discipline or a raging disease among the Russian soldiers. Perhaps it was never the aim to conquer Viborg, only to ravage the areas surrounding the town as a demonstration of power.
Question: How many men came from Sweden to help Finland?

SOLUTION: number

PROBLEM: Passage: The Steelers opened up their regular season on the road against their old AFC North division rivals, the Baltimore Ravens. The Ravens scored quickly on their first drive, when only three plays into the game, Baltimore wide receiver Anquan Boldin caught a 27-yard touchdown pass from quarterback Joe Flacco. The Ravens scored again on the ensuing drive when running back Ray Rice ran in a 1-yard touchdown, putting Baltimore on top 14-0 early in the first quarter. The Steelers battled back on the next drive, driving down to the Ravens 11-yard line. Pittsburgh scored on a third-and-goal play when wide receiver Emmanuel Sanders caught a touchdown in the back of the end zone from quarterback Ben Roethlisberger. The Ravens responded by scoring again, this time on an 11-yard pass from Flacco to Rice. At halftime the Ravens led 21-7, just like in the 2010 playoffs. But unlike that game, the Ravens did not let up their dominance in the second half. On Pittsburgh's first play from scrimmage in the second quarter, Ravens defensive lineman Haloti Ngata stripped Roethlisberger of the football and recovered it at the Steelers 18-yard line. The Ravens scored yet again when tight end Ed Dickson caught an 18-yard touchdown pass from Joe Flacco. A two-point conversion by punter/holder Sam Koch put the Ravens on top 29-7. The Ravens never looked back, and put up two more Billy Cundiff field goals to close out the game 35-7. The Steelers finished with 7 turnovers in the game. The loss marked the Steelers first opening day loss in 8 years, and left Pittsburgh at the bottom of the division with an 0-1 record.
