Problem: Boston:

In 1950, whites represented 94.7% of Boston's population. From the 1950s to the end of the 20th century, the proportion of non-Hispanic whites in the city declined; in 2000, non-Hispanic whites made up 49.5% of the city's population, making the city majority-minority for the first time. However, in recent years the city has experienced significant gentrification, in which affluent whites have moved into formerly non-white areas. In 2006, the US Census Bureau estimated that non-Hispanic whites again formed a slight majority. But as of 2010, in part due to the housing crash, as well as increased efforts to make more affordable housing more available, the minority population has rebounded. This may also have to do with an increased Latino population and more clarity surrounding US Census statistics, which indicate a Non-Hispanic White population of 47 percent (some reports give slightly lower figures).

What year did minorities become the majority of the population for the first time?
---
A: 2000

Genocide has become an official term used in international relations. The word genocide was not in use before 1944. Before this, in 1941, Winston Churchill described the mass killing of Russian prisoners of war and civilians as "a crime without a name". In that year, a Polish-Jewish lawyer named Raphael Lemkin, described the policies of systematic murder founded by the Nazis as genocide. The word genocide is the combination of the Greek prefix geno- (meaning tribe or race) and caedere (the Latin word for to kill). The word is defined as a specific set of violent crimes that are committed against a certain group with the attempt to remove the entire group from existence or to destroy them.
What was the name of the Polish-Jewish lawyer who first described Nazi atrocities as "genocide?" 
A: Raphael Lemkin


Context and question: The Enlightenment – known in French as the Siècle des Lumières, the Century of Enlightenment, and in German as the Aufklärung – was a philosophical movement which dominated the world of ideas in Europe in the 18th century. The Enlightenment included a range of ideas centered on reason as the primary source of authority and legitimacy, and came to advance ideals such as liberty, progress, tolerance, fraternity, constitutional government and ending the abuses of the church and state. In France, the central doctrines of the Lumières were individual liberty and religious tolerance, in opposition to the principle of absolute monarchy and the fixed dogmas of the Roman Catholic Church. The Enlightenment was marked by increasing empiricism, scientific rigor, and reductionism, along with increased questioning of religious orthodoxy.
Which movement dominated the world of ideas in Europe in the 18th century?

Question: Neptune has a planetary ring system, though one much less substantial than that of Saturn. The rings may consist of ice particles coated with silicates or carbon-based material, which most likely gives them a reddish hue. The three main rings are the narrow Adams Ring, 63,000 km from the centre of Neptune, the Le Verrier Ring, at 53,000 km, and the broader, fainter Galle Ring, at 42,000 km. A faint outward extension to the Le Verrier Ring has been named Lassell; it is bounded at its outer edge by the Arago Ring at 57,000 km.
Is there an answer to this question: Where is the La Verrier ring from the center of Neptune?

Answer: 53,000 km

The city is also home to the Heineken Brewery that brews Murphy's Irish Stout and the nearby Beamish and Crawford brewery (taken over by Heineken in 2008) which have been in the city for generations. 45% of the world's Tic Tac sweets are manufactured at the city's Ferrero factory. For many years, Cork was the home to Ford Motor Company, which manufactured cars in the docklands area before the plant was closed in 1984. Henry Ford's grandfather was from West Cork, which was one of the main reasons for opening up the manufacturing facility in Cork. But technology has replaced the old manufacturing businesses of the 1970s and 1980s, with people now working in the many I.T. centres of the city – such as Amazon.com, the online retailer, which has set up in Cork Airport Business Park.
Why was it natural to have Ford Motor Company based in Cork?
A:
Henry Ford's grandfather was from West Cork
