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: 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?

Answer: date

Question: Passage: With the borders secured with treaties and agreements at east and south, Mustafa Kemal was now in a commanding position. The Nationalists were then able to demand on 5 September 1922 that the Greeks evacuate East Thrace, Imbros and Tenedos as well as Asia Minor, and the Maritsa River should again become the western border of Turkey, as before 1914. The British were prepared to defend the neutral zone of Constantinople and the Straits and the French asked Kemal to respect it, to which he agreed on 28 September. However, France, Italy, Yugoslavia, and the British Dominions objected to a new war. France, Italy and Britain called on Mustafa Kemal to enter into cease-fire negotiations. In return, on 29 September Kemal asked for the negotiations to be started at Mudanya. Negotiations at Mudanya began on 3 October and it was concluded with the Armistice of Mudanya. This was agreed on 11 October, two hours before the British intended to engage at Chanak, and signed the next day. The Greeks initially refused to agree but did so on 13 October. Factors persuading Turkey to sign may have included the arrival of British reinforcements. The armistice then made it possible for the allies to recognise the Turkish claim to East Thrace, which was agreed to at the Lausanne Conference on 20 November 1922.
Question: On what date was the armistice concluded?

Answer: date
