Article: In most parts of medieval Europe, the upper class obtained the sole rights to hunt in certain areas of a feudal territory. Game in these areas was used as a source of food and furs, often provided via professional huntsmen, but it was also expected to provide a form of recreation for the aristocracy. The importance of this proprietary view of game can be seen in the Robin Hood legends, in which one of the primary charges against the outlaws is that they "hunt the King's deer". In contrast, settlers in Anglophone colonies gloried democratically in hunting for all.

Question: The importance of can be seen in what legends?
Ans: Robin Hood

Article: Among the challenges being faced to improve the efficiency of LED-based white light sources is the development of more efficient phosphors. As of 2010, the most efficient yellow phosphor is still the YAG phosphor, with less than 10% Stoke shift loss. Losses attributable to internal optical losses due to re-absorption in the LED chip and in the LED packaging itself account typically for another 10% to 30% of efficiency loss. Currently, in the area of phosphor LED development, much effort is being spent on optimizing these devices to higher light output and higher operation temperatures. For instance, the efficiency can be raised by adapting better package design or by using a more suitable type of phosphor. Conformal coating process is frequently used to address the issue of varying phosphor thickness.

Question: What is the most efficient yellow phosphor?
Ans: YAG phosphor

Article: At the 2010 United States Census, there were 39,558 people, 15,504 households, and 8,558 families residing in the city. The population density was 3,680.8 per square mile (1,421.2/km2). There were 20,013 housing units at an average density of 1,862.2 per square mile (719.0/km2). The racial makeup of the city was 26.65% (10,543) White, 38.29% (15,148) Black or African American, 0.61% (242) Native American, 15.55% (6,153) Asian, 0.05% (18) Pacific Islander, 14.03% (5,549) from other races, and 4.82% (1,905) from two or more races. Hispanics or Latinos of any race were 30.45% (12,044) of the population.

Question: How many housing units were in Atlantic City during the 2010 United States Census?
Ans: 20,013

Article: Draught beer's environmental impact can be 68% lower than bottled beer due to packaging differences. A life cycle study of one beer brand, including grain production, brewing, bottling, distribution and waste management, shows that the CO2 emissions from a 6-pack of micro-brew beer is about 3 kilograms (6.6 pounds). The loss of natural habitat potential from the 6-pack of micro-brew beer is estimated to be 2.5 square meters (26 square feet). Downstream emissions from distribution, retail, storage and disposal of waste can be over 45% of a bottled micro-brew beer's CO2 emissions. Where legal, the use of a refillable jug, reusable bottle or other reusable containers to transport draught beer from a store or a bar, rather than buying pre-bottled beer, can reduce the environmental impact of beer consumption.

Question: What beer is better for the environment than bottled beer?
Ans:
Draught beer's
