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: Since the end of World War II, in part due to industrial size and the onset of the Cold War, the United States has often been a proponent of reduced tariff-barriers and free trade. The U.S. helped establish the General Agreement on Tariffs and Trade and later the World Trade Organization ; although it had rejected an earlier version in the 1950s . Since the 1970s, U.S. governments have negotiated managed-trade agreements, such as the North American Free Trade Agreement in the 1990s, the Dominican Republic-Central America Free Trade Agreement in 2006, and a number of bilateral agreements . In Europe, six countries formed the European Coal and Steel Community in 1951 which became the European Economic Community in 1958. Two core objectives of the EEC were the development of a common market, subsequently renamed the single market, and establishing a customs union between its member states. After expanding its membership, the EEC became the European Union in 1993. The European Union, now the world's largest single market, has concluded free trade agreements with many countries around the world.
Question: When did the countries that later formed the European Union first join?

SOLUTION: date

PROBLEM: 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?

SOLUTION: number

PROBLEM: Passage: In July and August 1433, Svitrigaila and his Livonian allies raided Lida, Kreva and Eisiskes and devastated the suburbs of Vilnius, Trakai and Kaunas. The hostilities were briefly stopped by horse plague. When Jogaila died in May 1434, the Order resumed its backing for Svitrigaila, who rallied his supporters, including knights from the Livonian Order, the Orthodox dukes, and his nephew Sigismund Korybut, a distinguished military commander of the Hussites. In July 1435, Svitrigaila foiled a coup against him in Smolensk. Coup leader Orthodox bishop Gerasim, consecrated as Metropolitan of Moscow in 1432, was burned at the stake. The final battle, at Pabaiskas, was fought in September 1435 near Ukmerge , northwest of Vilnius. It is estimated to have involved 30,000 men on both sides. Svitrigaila's army, led by Sigismund Korybut, was split by the attacking Lithuanian-Polish army, led by Michael Zygimantaitis, and soundly defeated. Svitrigaila, with a small group of followers, managed to escape to Polotsk. The Livonian Order had suffered a great defeat, sometimes compared to that which had been inflicted on the Teutonic Knights at Grunwald in 1410. On 31 December 1435 the Teutonic Knights signed a peace treaty at Brzesc Kujawski. They agreed to cease their support for Svitrigaila, and in the future to support only Grand Dukes who had been properly elected jointly by Poland and Lithuania. The treaty did not change the borders that had been set by the Treaty of Melno in 1422. The Peace of Brzesc Kujawski showed that the Teutonic Knights had lost their universal missionary status. The Teutonic and Livonian Orders no longer interfered in Polish-Lithuanian affairs; instead, Poland and Lithuania would involve themselves in the Thirteen Years' War , the civil war that would tear Prussia in half.
Question: How many total men were present in the final battle?

SOLUTION:
number
