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.

[EX Q]: 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?

[EX Q]: Passage:  Coming off their overtime win at San Diego, the Broncos traveled to the Mall of America Field at the Hubert H. Humphrey Metrodome for an interconference duel with the Minnesota Vikings. The game's first points came from the Vikings, when defensive end Jared Allen tackled running back Willis McGahee in the end zone for a safety. The Broncos grabbed the lead when linebacker Mario Haggan returned an interception off Vikings' quarterback Christian Ponder 16 yards for a touchdown. Vikings' kicker Ryan Longwell made a 40-yard field goal, then the Vikings reclaimed the lead in the second quarter, on a 19-yard touchdown pass from Ponder to tight end Kyle Rudolph, followed by another field goal by Longwell, this time from 25 yards, just before halftime. The Broncos narrowed Minnesota's lead in the third quarter, with a 21-yard touchdown pass from quarterback Tim Tebow to wide receiver Demaryius Thomas, but the Vikings countered with a 52-yard touchdown pass from Ponder to wide receiver Percy Harvin. The Broncos responded with a 41-yard touchdown pass from Tebow to Thomas. Ponder then threw a 48-yard touchdown pass to Harvin to give Minnesota a 29-21 lead. On the Broncos' next possession, McGahee rushed 24 yards for a touchdown and Tebow scrambled for a two-point conversion to tie the game at 29. The Vikings subsequently reclaimed the lead on Longwell's 39-yard field goal with 3:06 left in the game. The Broncos answered with kicker Matt Prater's 46-yard field goal with 1:33 left to tie the game at 32. On the Vikings' ensuing possession, Broncos' cornerback Andr&#233; Goodman returned an interception off Ponder to the Vikings' 15-yard line. Six plays later, Prater nailed the game-winning 23-yard field goal as time expired to give the Broncos their fifth consecutive win.
