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: In November 1944, after Greece was liberated from Germany, old drachmae were exchanged for new ones at the rate of 50,000,000,000 to 1. Only paper money was issued. The government issued notes of 1, 5, 10 and 20 drachmae, with the Bank of Greece issuing 50-, 100-, 500-, 1000-, 5000-, and 10,000-drachma notes. This drachma also suffered from high inflation. The government later issued 100-, 500-, and 1000-drachma notes, and the Bank of Greece issued 20,000-and 50,000-drachma notes. Third modern drachma coins The first issue of coins minted in 1954 consisted of holed aluminium 5-, 10- and 20-lepton pieces, with 50-lepton, 1-, 2-, 5- and 10-drachma pieces in cupro-nickel. A silver 20-drachma piece was issued in 1960, replacing the 20-drachma banknote, and also minted only in collector sets in 1965.  Coins in denominations from 50 lepta to 20 drachmae carried a portrait of Paul of Greece (1947–1964). New coins were introduced in 1966, ranging from 50 lepta to 10 drachmae, depicting Constantine II of Greece (1964–1974). A silver 30 drachma coin for the centennial of Greeces royal dynasty was minted in 1963.  The following year a non-circulating coin of this value was produced to commemorate the royal wedding.  The reverse of all coins was altered in 1971 to reflect the military junta which was in power from 1967 to 1974. This design included a soldier standing in front of the flames of the rising phoenix.
Question: What year was the non-circulating 30 drachma coin issued to commemorate the royal wedding?

SOLUTION: date

The median age was 40.2 years. For every 100 females, there were 98.5 males. For every 100 females age 18 and over, there were 96.6 males.
Question: Which age group is larger: under the age of 18 or 65 years of age or older?

PROBLEM: Passage: According to the Yuanshi, the Yuan fleet set out with an estimated 15,000 Mongol and Chinese soldiers and 1,600-8,000 Korean soldiers in 300 large vessels and 400-500 smaller craft along with several thousand sailors, although figures vary considerably depending on the source and many modern historians consider the numbers exaggerated. The primary port for the operation was Quanzhou in Fujian, then the center of China's maritime trade. They landed on Komodahama beach on Tsushima Island on October 5, 1274. Sō Sukekuni, governor of Tsushima, led a cavalry unit of 80 to defend the island, but he and his outnumbered unit were killed in the engagement. The Mongols and Koreans subsequently invaded Iki. Tairano Takakage, the Governor of Iki, fought the invaders with about 100 of his cavalrymen, but he killed himself after his unit was defeated. The Mongol forces landed on November 19 in Hakata Bay, a short distance from Dazaifu, the ancient administrative capital of Kyūshū. The following day brought the Battle of Bun'ei , also known as the "First Battle of Hakata Bay". The Japanese coalition force opposing them included 120 armed samurai each with a warband and likely numbered between 3,000 and 6,000 strong. Later accounts have both sides believing themselves to be drastically outnumbered by the enemy; the Yuanshi provides an estimate of 102,000 for the Japanese force, while the Japanese Hachiman Gudokun describes the invaders as outnumbering the Japanese 10 to 1. Conlan argues that the Yuanshi's account of the battle suggests that both the Japanese and Yuan forces were of similar size. Conlan estimated that both armies numbered around 3,000 each .
Question: What day did the Battle of Bun'ei take place?
