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: 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: Coming off their road win over the Chiefs, the Chargers went home, donned their alternate uniforms, and played a Week 8 divisional rematch with the Oakland Raiders.  In the first quarter, San Diego struck first as running back LaDainian Tomlinson got a 6-yard touchdown run.  The Raiders would answer in the second quarter with a 3-yard touchdown run by running back Justin Fargas, yet the Chargers stormed on as quarterback Philip Rivers hooked up wide receiver Vincent Jackson on an 8-yard touchdown pass, followed by Tomlinson getting a 10-yard touchdown run.  Oakland would close out the half with a 48-yard field goal by kicker Sebastian Janikowski. In the second half, the Raiders would slowly try to rally as Janikowski nailed a 41-yard field goal in the third quarter and a 41-yard field goal in the fourth.  Afterwards, San Diego pulled away as kicker Nate Kaeding booted a 28-yard field goal. With their 13th-straight win over Oakland, the Chargers improved to 4-3.

PROBLEM: Passage: The Free State government had started peace negotiations in early May, which broke down. The High Court of Justice in Ireland  ruled on 31 July 1923 that a state of war no longer existed, and consequently the internment of republicans, permitted under common law only in wartime, was now illegal. Without a formal peace, holding 13,000 prisoners and worried that fighting could break out again at any time, the government enacted two Public Safety  Acts on 1 and 3 August 1923, to permit continued internment and other measures. Thousands of Anti-Treaty IRA members  were arrested by the Free State forces in the weeks and months after the end of the war, when they had dumped their arms and returned home. On 27 August 1923, a general election was held, which Cumann na nGaedheal, the pro-Free State party, won with about 40% of the first-preference vote. The Republicans, represented by Sinn Féin, won about 27% of the vote. Many of their candidates and supporters were still imprisoned before, during and after the election. In October 1923, around 8,000 of the 12,000 Republican prisoners in Free State gaols went on a hunger strike. The strike lasted for 41 days and met little success . However, most of the women prisoners were released shortly thereafter and the hunger strike helped concentrate the Republican movement on the prisoners and their associated organisations. In July, de Valera had recognised the Republican political interests lay with the prisoners and went so far as to say:
