input question: Extract the answer to the question from the following context. Question: What was Harold Urey related to? Context: Hydrogen was liquefied for the first time by James Dewar in 1898 by using regenerative cooling and his invention, the vacuum flask. He produced solid hydrogen the next year. Deuterium was discovered in December 1931 by Harold Urey, and tritium was prepared in 1934 by Ernest Rutherford, Mark Oliphant, and Paul Harteck. Heavy water, which consists of deuterium in the place of regular hydrogen, was discovered by Urey's group in 1932. Francois Isaac de Rivaz built the first de Rivaz engine, an internal combustion engine powered by a mixture of hydrogen and oxygen in 1806. Edward Daniel Clarke invented the hydrogen gas blowpipe in 1819. The Dobereiner's lamp and limelight were invented in 1823.???
output answer: Urey's group

input question: Extract the answer to the question from the following context. Question: What year did the Great Migration temporarily end? Context: As of 2010, those of African ancestry accounted for 16.0% of Florida's population, which includes African Americans. Out of the 16.0%, 4.0% (741,879) were West Indian or Afro-Caribbean American. During the early 1900s, black people made up nearly half of the state's population. In response to segregation, disfranchisement and agricultural depression, many African Americans migrated from Florida to northern cities in the Great Migration, in waves from 1910 to 1940, and again starting in the later 1940s. They moved for jobs, better education for their children and the chance to vote and participate in society. By 1960 the proportion of African Americans in the state had declined to 18%. Conversely large numbers of northern whites moved to the state.[citation needed] Today, large concentrations of black residents can be found in northern and central Florida. Aside from blacks descended from African slaves brought to the US south, there are also large numbers of blacks of West Indian, recent African, and Afro-Latino immigrant origins, especially in the Miami/South Florida area. In 2010, Florida had the highest percentage of West Indians in the United States, with 2.0% (378,926) from Haitian ancestry, and 1.3% (236,950) Jamaican. All other (non-Hispanic) Caribbean nations were well below 0.1% of Florida residents.???
output answer: 1940

input question: Extract the answer to the question from the following context. Question: __ territory was inhabited by the Ciboney Taino people. Context: According to a study by Dr. Paul Brest, Hispanics or "Latinos" include immigrants who are descendants of immigrants from the countries comprising Central and South America. In 1991, Mexican Americans, Puerto Ricans, and Cuban Americans made up 80% of the Latino population in the United States. Latinos are disadvantaged compared to White Americans and are more likely to live in poverty. They are the least well educated major ethnic group and suffered a 3% drop in high school completion rate while African Americans experienced a 12% increase between 1975-1990. In 1990, they constituted 9% of the population, but only received 3.1% of the bachelors's degrees awarded. At times when it is favorable to lawmakers, Latinos were considered "white" by the Jim Crow laws during the Reconstruction. In other cases, according to Paul Brest, Latinos have been classified as an inferior race and a threat to white purity. Latinos have encountered considerable discrimination in areas such as employment, housing, and education. Brest finds that stereotypes continue to be largely negative and many perceive Latinos as "lazy, unproductive, and on the dole." Furthermore, native-born Latino-Americans and recent immigrants are seen as identical since outsiders tend not to differentiate between Latino groups.???
output answer: Cuban

input question: Extract the answer to the question from the following context. Question: Which lamps, from the ones mentioned, do not have an initialism? Context: Incandescent bulbs have been replaced in many applications by other types of electric light, such as fluorescent lamps, compact fluorescent lamps (CFL), cold cathode fluorescent lamps (CCFL), high-intensity discharge lamps, and light-emitting diode lamps (LED). Some jurisdictions, such as the European Union, China, Canada and United States, are in the process of phasing out the use of incandescent light bulbs while others, including Colombia, Mexico, Cuba, Argentina, Brazil and Australia, have prohibited them already.???
output answer:
high-intensity discharge lamps
