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: The First Utrecht Civil War  took place between 1470 and 1474 when the Hook and Cod wars spilled over into the Bishopric of Utrecht. David of Burgundy, illegitimate son of Philip the Good, Duke of Burgundy had been  appointed as bishop of Utrecht in 1456 with support of the Cods. The Utrecht chapters, however, had elected the Hook-favoured provost Gijsbrecht van Brederode as bishop. But Philip the Good used force to make David's appointment be accepted. Nevertheless, opposition against his rule remained, and David of Burgundy even found it safer to leave the city of Utrecht and take up residence in Wijk bij Duurstede. The van Brederode family was at the center of the opposition. In 1470, David of Burgundy imprisoned Gijsbrecht van Brederode and his brother Reinoud II van Brederode, and had them tortured. This action stirred up the century old animosity between the Hooks who supported the family van Brederode and the Cods who supported Burgundy. A civil war broke out that lasted until 1474.The status-quo returned, until a Second Utrecht Civil War broke out in 1481.
Question: Why did he  take up residence in Wijk bij Duurstede?

SOLUTION: span

PROBLEM: Passage: On 28 March 1193 Richard was brought to Speyer and handed over to Henry VI, Holy Roman Emperor, who imprisoned him in Trifels Castle. Henry VI was aggrieved by the support the Plantagenets had given to the family of Henry the Lion and by Richard's recognition of Tancred in Sicily. Henry VI needed money to raise an army and assert his rights over southern Italy and continued to hold Richard for ransom.  In response, Pope Celestine III excommunicated Henry VI, as he had Duke Leopold, for the continued wrongful imprisonment of Richard. Richard famously refused to show deference to the emperor and declared to him, "I am born of a rank which recognises no superior but God". Despite his complaints, the conditions of his captivity were not severe. The emperor demanded that 150,000 marks  be delivered to him before he would release the king, the same amount raised by the Saladin tithe only a few years earlier, and 2-3 times the annual income for the English Crown under Richard. Richard's mother, Eleanor of Aquitaine, worked to raise the ransom. Both clergy and laymen were taxed for a quarter of the value of their property, the gold and silver treasures of the churches were confiscated, and money was raised from the scutage and the carucage taxes. At the same time, John, Richard's brother, and King Philip of France offered 80,000 marks for the Emperor to hold Richard prisoner until Michaelmas 1194. The emperor turned down the offer. The money to rescue the King was transferred to Germany by the emperor's ambassadors, but "at the king's peril" , and finally, on 4 February 1194 Richard was released. Philip sent a message to John: "Look to yourself; the devil is loose".
