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.

Question: 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?

Answer: date


Question: Passage: The immediate background was Napoleonic France's defeat and surrender in May 1814, which brought an end to 25 years of nearly continuous war. Negotiations continued despite the outbreak of fighting triggered by Napoleon's dramatic return from exile and resumption of power in France during the Hundred Days of March to July 1815. The Congress's "final act" was signed nine days before his final defeat at Waterloo on 18 June 1815. The Congress has often been criticized for causing the subsequent suppression of the emerging national and liberal movements, and it has been seen as a reactionary movement for the benefit of traditional monarchs. However, others praise it for having created relatively long-term stability and peaceful conditions in most of Europe. In a technical sense, the "Congress of Vienna" was not properly a congress: it never met in plenary session, and most of the discussions occurred in informal, face-to-face sessions among the Great Powers of Austria, Britain, France, Russia, and sometimes Prussia, with limited or no participation by other delegates. On the other hand, the congress was the first occasion in history where, on a continental scale, national representatives came together to formulate treaties instead of relying mostly on messages among the several capitals. The Congress of Vienna settlement, despite later changes, formed the framework for European international politics until the outbreak of the First World War in 1914.
Question: On what date was the Congress's "final act" signed?

Answer: date


Question: Passage: There was interest in his ideas but they remained untested; this changed with the outbreak of the 1688-1697 Nine Years War which placed great emphasis on manoeuvre and siege warfare. Van Coehoorn was present at the capture of Kaiserswerth and Bonn in 1690; his exact role is unclear but Frederick of Prussia was impressed enough to offer him a position as Major-General in his army. He refused and in 1691 William appointed him commander of Namur where he was finally able to implement his ideas on defensive strategy. Namur was divided into the 'City' on the flat northern bank of the River Sambre and the Citadel on high ground to the south controlling access to the Sambre and Meuse rivers. Van Coehoorn strengthened the 'inner' Citadel with new outworks at Fort William and La Casotte but did not have time to do the same for the 'outer' City area. His garrison of 5,000  was also too small for the active defence he had planned, many being poorly-trained Spanish troops with little interest in fighting for the Dutch.
Question: When did Van Coehoorn refused Frederick of Prussia the position he offered him?

Answer:
date
