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: The season started about as well as it could have, as the Washington Redskins started the season 62, with their two losses coming by a combined 11 points to the 2008 New York Giants season and 2008 St. Louis Rams season. Furthermore, Redskins star Clinton Portis led the NFL in rushing yards and Jason Campbell was just 40 pass attempts away from breaking Bernie Kosars record of consecutive passes to start the season without an interception. However, things turned for the worse on the eve of the United States presidential election, 2008, when they were routed 236 by the 2008 Pittsburgh Steelers season and Clinton Portis injuries finally caught up to him. The Redskins continued to struggle, falling all the way to 77, with their only win during that six-week period being a 3-point victory of the then-28 2008 Seattle Seahawks season, who would finish the season 4-12. The Redskins managed to upset the 2008 Philadelphia Eagles season in Week 16, but were eliminated from playoff contention after the 2008 Atlanta Falcons season defeated the 2008 Minnesota Vikings season 2417 that same week. The Redskins lost the final game of the season 2724 to the 2008 San Francisco 49ers season, despite having a 177 lead at halftime, losing on a Joe Nedney field goal as time expired.
Question: How many points did the Vikings lose by against the Falcons?

Answer: number

Question: Passage: Minority ethnic groups include White people in Zimbabwe, who make up less than 1% of the total population. White Zimbabweans are mostly of British origin, but there are also Afrikaner, Greeks in Zimbabwe, Portuguese people, Franco-Mauritian and Dutch people communities. The white population dropped from a peak of around 278,000 or 4.3% of the population in 1975 to possibly 120,000 in 1999, and was estimated to be no more than 50,000 in 2002, and possibly much less. The 2012 census lists the total white population at 28,782 (roughly 0.22% of the population), one-tenth of its 1975 estimated size. Most emigration has been to the United Kingdom (between Zimbabweans in the United Kingdom Britons are of Rhodesian or Zimbabwean origin), South Africa, Botswana, Zambia, Canada, Australia and New Zealand. Coloureds form 0.5% of the population, and various Asian people ethnic groups, mostly of Indian and Chinese origin, are also 0.5%.
Question: Was the White population estimated to be higher in 1975 or 1999?
