Input: Black people
Different societies apply differing criteria regarding who is classified as "black", and these social constructs have also changed over time. In a number of countries, societal variables affect classification as much as skin color, and the social criteria for "blackness" vary. For example, in North America the term black people is not necessarily an indicator of skin color or majority ethnic ancestry, but it is instead a socially based racial classification related to being African American, with a family history associated with institutionalized slavery. In South Africa and Latin America, for instance, mixed-race people are generally not classified as "black." In South Pacific regions such as Australia and Melanesia, European colonists applied the term "black" or it was used by populations with different histories and ethnic origin.

What factors can affect the classification of "blackness"?
Output: societal variables

Input: Education
In 2012, the modern use of electronic educational technology (also called e-learning) had grown at 14 times the rate of traditional learning.[clarification needed] Open education is fast growing to become the dominant form of education, for many reasons such as its efficiency and results compared to traditional methods. Cost of education has been an issue throughout history, and a major political issue in most countries today. Online courses often can be more expensive than face-to-face classes. Out of 182 colleges surveyed in 2009 nearly half said tuition for online courses was higher than for campus based ones. Many large university institutions are now starting to offer free or almost free full courses such as Harvard, MIT and Berkeley teaming up to form edX. Other universities offering open education are Stanford, Princeton, Duke, Johns Hopkins, Edinburgh, U. Penn, U. Michigan, U. Virginia, U. Washington, and Caltech. It has been called the biggest change in the way we learn since the printing press. Despite favorable studies on effectiveness, many people may still desire to choose traditional campus education for social and cultural reasons.

Which type of schooling can be most expensive?
Output: Online courses

Input: Premier League
The Premier League distributes a portion of its television revenue to clubs that are relegated from the league in the form of "parachute payments". Starting with the 2013–14 season, these payments are in excess of £60 million over four seasons. Though designed to help teams adjust to the loss of television revenues (the average Premier League team receives £55 million while the average Football League Championship club receives £2 million), critics maintain that the payments actually widen the gap between teams that have reached the Premier League and those that have not, leading to the common occurrence of teams "bouncing back" soon after their relegation. For some clubs who have failed to win immediate promotion back to the Premier League, financial problems, including in some cases administration or even liquidation have followed. Further relegations down the footballing ladder have ensued for several clubs unable to cope with the gap.

How does this compare an average Premier League team?
Output: the average Premier League team receives £55 million

Input: United States dollar
Early releases of the Washington coin included error coins shipped primarily from the Philadelphia mint to Florida and Tennessee banks. Highly sought after by collectors, and trading for as much as $850 each within a week of discovery, the error coins were identified by the absence of the edge impressions "E PLURIBUS UNUM IN GOD WE TRUST 2007 P". The mint of origin is generally accepted to be mostly Philadelphia, although identifying the source mint is impossible without opening a mint pack also containing marked units. Edge lettering is minted in both orientations with respect to "heads", some amateur collectors were initially duped into buying "upside down lettering error" coins. Some cynics also erroneously point out that the Federal Reserve makes more profit from dollar bills than dollar coins because they wear out in a few years, whereas coins are more permanent. The fallacy of this argument arises because new notes printed to replace worn out notes, which have been withdrawn from circulation, bring in no net revenue to the government to offset the costs of printing new notes and destroying the old ones. As most vending machines are incapable of making change in banknotes, they commonly accept only $1 bills, though a few will give change in dollar coins.

How much were error coins initially worth for collectors?
Output:
profit
