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: Under a much broader definition (including people that have given up searching for employment) two different studies determined the unemployment rate to be 36.7% (2004) and 51.2% (2008), respectively. This estimate considers people in the Informal sector as employed. 72% of jobless people have been unemployed for two years or more. Labour and Social Welfare Minister Immanuel Ngatjizeko praised the 2008 study as "by far superior in scope and quality to any that has been available previously", but its methodology has also received criticism. The total number of formally employed people stood at 400,000 in 1997 and fell 330,000 in 2008, according to a government survey. The NSA 2012 study counted 396,000 formal employees. Of annually 25,000 school leavers only 8,000 gain formal employment-largely a result of a failed Education in Namibia.
Question: Were more people employed in 1997 or 2008?

SOLUTION: date

PROBLEM: Passage: Income inequality has become a hotly debated topic globally. According to the CIA World Factbook, U.S. income inequality ranked 41st highest among 156 countries in 2017 (i.e., 74% of countries have a more equal income distribution). According to the Congressional Budget Office, the top 1% of income households earned about a 9% share of the pre-tax income in 1979, versus 19% in 2007 and 17% in 2014. For after-tax income, these figures were 7%, 17%, and 13%, respectively. These figures indicate the share of income earned by top earners more than doubled between 1979 and 2007, then fell somewhat following the Great Recession, and the higher tax rates and re-distributive policies applied by President Barack Obama in 2013 (i.e., expiration of the Bush Tax Cuts for the top 1% and subsidies for lower income persons via the Affordable Care Act). Recasting the 2012 income using the 1979 income distribution (representing the more egalitarian 1950-1980 period), the bottom 99% of families would have averaged about $7,100 more income. Income inequality in the United States has grown from 2005 to 2012 in more than 2 out of 3 metropolitan areas.
Question: Which year saw the top 1% earn the most share of the pre-tax income, 1979, 2007, or 2014?

SOLUTION: date

PROBLEM: Passage: Bayinnaung now looked to Siam, which successfully fought off the first Burmese invasion in 1547-1549. However, Bayinnaung now had a far larger empire at his disposal. Knowing that Siam be much more difficult than Shan states and Lan Na campaigns, Bayinnaung assembled the largest army yet—60,000 men, 2400 horses and 360 elephants, two and a half times larger than his previous high. The army would have been larger but the ruler of Chiang Mai, Mekuti, did not send in his share of the levy. Four Burmese armies invaded northern Siam in November 1563, and had overcome Siamese stands at Kamphaeng Phet, Sukhothai and Phitsanulok by January 1564. Armies then came down on Ayutthaya but were kept at bay for days by Portuguese warships and batteries at the harbour. Siamese defences collapsed after the Burmese captured the Portuguese ships on 7 February 1564 . King Maha Chakkraphat of Siam surrendered on 18 February 1564 . The king and crown prince Ramesuan were brought back to Pegu as hostages. Bayinnaung left Mahinthrathirat, one of Maha Chakkraphat's sons as vassal king, along with a garrison of 3,000 men.
Question: Who was Maha Chakkraphat's son?
