Problem: East India Company:

At this time, Britain and France became bitter rivals. Frequent skirmishes between them took place for control of colonial possessions. In 1742, fearing the monetary consequences of a war, the British government agreed to extend the deadline for the licensed exclusive trade by the company in India until 1783, in return for a further loan of 1 million. Between 1756 and 1763, the Seven Years' War diverted the state's attention towards consolidation and defence of its territorial possessions in Europe and its colonies in North America.

What year was the Seven Years' War prevented?

A: unanswerable

Problem: The Protestant Reformation inspired a literal interpretation of the Bible, with concepts of creation that conflicted with the findings of an emerging science seeking explanations congruent with the mechanical philosophy of Rene Descartes and the empiricism of the Baconian method. After the turmoil of the English Civil War, the Royal Society wanted to show that science did not threaten religious and political stability. John Ray developed an influential natural theology of rational order; in his taxonomy, species were static and fixed, their adaptation and complexity designed by God, and varieties showed minor differences caused by local conditions. In God's benevolent design, carnivores caused mercifully swift death, but the suffering caused by parasitism was a puzzling problem. The biological classification introduced by Carl Linnaeus in 1735 also viewed species as fixed according to the divine plan. In 1766, Georges Buffon suggested that some similar species, such as horses and asses, or lions, tigers, and leopards, might be varieties descended from a common ancestor. The Ussher chronology of the 1650s had calculated creation at 4004 BC, but by the 1780s geologists assumed a much older world. Wernerians thought strata were deposits from shrinking seas, but James Hutton proposed a self-maintaining infinite cycle, anticipating uniformitarianism.
Who proposed that life is a self-maintaining, infinite cycle?

Answer: James Hutton

Context and question: Directly underneath the State Apartments is a suite of slightly less grand rooms known as the semi-state apartments. Opening from the Marble Hall, these rooms are used for less formal entertaining, such as luncheon parties and private audiences. Some of the rooms are named and decorated for particular visitors, such as the 1844 Room, decorated in that year for the State visit of Tsar Nicholas I of Russia, and, on the other side of the Bow Room, the 1855 Room, in honour of the visit of Emperor Napoleon III of France. At the centre of this suite is the Bow Room, through which thousands of guests pass annually to the Queen's Garden Parties in the Gardens. The Queen and Prince Philip use a smaller suite of rooms in the north wing.
Which European chef is The 1845 Room named after?
Answer: unanswerable

Question: Stochastic computing was first introduced in a pioneering paper by von Neumann in 1953. However, the theory could not be implemented until advances in computing of the 1960s. He also created the field of cellular automata without the aid of computers, constructing the first self-replicating automata with pencil and graph paper. The concept of a universal constructor was fleshed out in his posthumous work Theory of Self Reproducing Automata. Von Neumann proved that the most effective way of performing large-scale mining operations such as mining an entire moon or asteroid belt would be by using self-replicating spacecraft, taking advantage of their exponential growth. His rigorous mathematical analysis of the structure of self-replication (of the semiotic relationship between constructor, description and that which is constructed), preceded the discovery of the structure of DNA. Beginning in 1949, von Neumann's design for a self-reproducing computer program is considered the world's first computer virus, and he is considered to be the theoretical father of computer virology.
Is there an answer to this question: How long before stochastic computing could be implemented?

Answer: advances in computing of the 1960s.

Since the early history of the United States, Amerindians, AfricanAmericans, and European Americans have been classified as belonging to different races. Efforts to track mixing between groups led to a proliferation of categories, such as mulatto and octoroon. The criteria for membership in these races diverged in the late 19th century. During Reconstruction, increasing numbers of Americans began to consider anyone with "one drop" of known "Black blood" to be Black, regardless of appearance.3 By the early 20th century, this notion was made statutory in many states.4 Amerindians continue to be defined by a certain percentage of "Indian blood" (called blood quantum). To be White one had to have perceived "pure" White ancestry. The one-drop rule or hypodescent rule refers to the convention of defining a person as racially black if he or she has any known African ancestry. This rule meant that those that were mixed race but with some discernible African ancestry were defined as black. The one-drop rule is specific to not only those with African ancestry but to the United States, making it a particularly African-American experience.
What did efforts to track mixing between different groups lead to?
A:
a proliferation of categories
