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: During the summer campaign of 1673, Turenne had the thankless task of trying to contain Leopold's troops under the command of Raimondo Montecuccoli. Montecuccoli finally joined with the Dutch troops of William III to besiege and take the city of Bonn from the French. In August 1673, The Habsburg monarchies of Spain and the Holy Roman Empire signed a formal alliance with the Republic that required that France be returned to her boundaries of 1659. This alliance was strengthened in October by Charles IV of Lorraine. Imperial and Dutch troops conquered the town of Naarden from the French on 13 September. The Spanish, who had yet to formally enter the war, declared war on the French on 16 October. At about the same time Frederick William re-entered the war against France. The position of Louis at this stage was bad enough, but it worsened when England made a separate peace, the Treaty of Westminster, with all of the nations arrayed against France on 19 February 1674. Charles II had been forced into making peace with the Republic by the Parliament which returned to session in October 1673.
Question: When did the Spanish declare war?
answer:
date

Passage: Superferry 14 was a large ferry destroyed by a bomb on 27 February 2004, killing 116 people in the Philippines' worst terrorist attack and the world's deadliest terrorist attack at sea. On that day, the 10,192 ton ferry sailed out of Manila with about 900 passengers and crew on board. A television set filled with 8 lb.  of TNT had been placed on board. 90 minutes out of port, the bomb exploded. 63 people were killed instantly and 53 were missing and presumed dead. Despite claims from terrorist groups, the blast was initially thought to have been an accident caused by a gas explosion. However, after divers righted the ferry five months after it had sunk, they found evidence of a bomb blast. A man called Redendo Cain Dellosa admitted to planting the bomb for Abu Sayyaf. Six suspects were arrested in connection with the bombing while the masterminds, Khadaffy Janjalani and Abu Sulaiman, were killed.
Question: When did the divers right the sunken ferry?
