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?

PROBLEM: Passage: Jordan played three seasons for coach Dean Smith at the North Carolina Tar Heels mens basketball. As a freshman, he was a member of the 1981–82 North Carolina Tar Heels mens basketball team in 1982 NCAA Division I Mens Basketball Tournament. Jordan joined the Bulls in 1984–85 NBA season as the 1984 NBA draft draft (sports) pick. He quickly emerged as a league star and entertained crowds with his prolific scoring. His leaping ability, demonstrated by performing slam dunks from the free throw line in Slam Dunk Contests, earned him the nicknames Air Jordan and His Airness. He also gained a reputation for being one of the best defensive players in basketball. In 1991 NBA Finals, he won his first NBA championship with the Bulls, and followed that achievement with titles in 1992 NBA Finals and 1993 NBA Finals, securing a "three-peat". Although Jordan abruptly retired from basketball before the beginning of the 1993–94 NBA season, and started a new career in Minor League Baseball, he returned to the Bulls in 1994–95 NBA season and led them to three additional championships in 1996 NBA Finals, 1997 NBA Finals, and 1998 NBA Finals, as well as a then-record List of NBA teams by single season win percentage in the 1995–96 NBA season. Jordan retired for a second time in 1998–99 NBA season, but returned for two more NBA seasons from 2001 to 2003 as a member of the Wizards.
Question: What year did Jordan first play for the North Carolina Tar Heels?

PROBLEM: Passage: The 19th century was dominated by the Hungarian struggle for independence and modernisation. The national insurrection against the Habsburgs began in the Hungarian capital Hungarian Revolution of 1848 and was defeated one and a half years later, with the help of the Russian Empire. 1867 was the year of Austro-Hungarian Compromise of 1867 that brought about the birth of Austria-Hungary. This made Budapest the twin capital of a dual monarchy. It was this compromise which opened the second great phase of development in the history of Budapest, lasting until World War I. In 1849 the Chain Bridge (Budapest) linking Buda with Pest was opened as the first permanent bridge across the Danube and in 1873 Buda and Pest were officially merged with the third part, Óbuda (Old Buda), thus creating the new metropolis of Budapest. The dynamic Pest grew into the countrys administrative, political, economic, trade and cultural hub. Ethnic Hungarians overtook Danube Swabians in the second half of the 19th century due to mass migration from the overpopulated rural Transdanubia and Great Hungarian Plain. Between 1851 and 1910 the proportion of Hungarians increased from 35.6% to 85.9%, Hungarian became the dominant language, and German was crowded out. The proportion of Jews peaked in 1900 with 23.6%. Due to the prosperity and the large Jewish community of the city at the start of the 20th century, Budapest was often called the "Jewish Mecca" or "Judapest". In 1918, Austria-Hungary lost the war and collapsed; Hungary declared itself an independent republic (Republic of Hungary). In 1920 the Treaty of Trianon partitioned the country, and as a result, Hungary lost over two-thirds of its territory, and about two-thirds of its inhabitants, including 3.3 million out of 15 million ethnic Hungarians.
Question: What year did the Hungarian Revolution end?
