Input: Detroit
While Blacks/African-Americans comprised only 13 percent of Michigan's population in 2010, they made up nearly 82 percent of Detroit's population. The next largest population groups were Whites, at 10 percent, and Hispanics, at 6 percent. According to the 2010 Census, segregation in Detroit has decreased in absolute and in relative terms. In the first decade of the 21st century, about two-thirds of the total black population in metropolitan area resided within the city limits of Detroit. The number of integrated neighborhoods has increased from 100 in 2000 to 204 in 2010. The city has also moved down the ranking, from number one most segregated to number four. A 2011 op-ed in The New York Times attributed the decreased segregation rating to the overall exodus from the city, cautioning that these areas may soon become more segregated. This pattern already happened in the 1970s, when apparent integration was actually a precursor to white flight and resegregation. Over a 60-year period, white flight occurred in the city. According to an estimate of the Michigan Metropolitan Information Center, from 2008 to 2009 the percentage of non-Hispanic White residents increased from 8.4% to 13.3%. Some empty nesters and many younger White people moved into the city while many African Americans moved to the suburbs.

What is the 2009 population of Whites in Detroit?
Output: 13.3%


Input: Article: In response to the early-to-mid-17th century "continental rationalism" John Locke (1632–1704) proposed in An Essay Concerning Human Understanding (1689) a very influential view wherein the only knowledge humans can have is a posteriori, i.e., based upon experience. Locke is famously attributed with holding the proposition that the human mind is a tabula rasa, a "blank tablet", in Locke's words "white paper", on which the experiences derived from sense impressions as a person's life proceeds are written. There are two sources of our ideas: sensation and reflection. In both cases, a distinction is made between simple and complex ideas. The former are unanalysable, and are broken down into primary and secondary qualities. Primary qualities are essential for the object in question to be what it is. Without specific primary qualities, an object would not be what it is. For example, an apple is an apple because of the arrangement of its atomic structure. If an apple was structured differently, it would cease to be an apple. Secondary qualities are the sensory information we can perceive from its primary qualities. For example, an apple can be perceived in various colours, sizes, and textures but it is still identified as an apple. Therefore, its primary qualities dictate what the object essentially is, while its secondary qualities define its attributes. Complex ideas combine simple ones, and divide into substances, modes, and relations. According to Locke, our knowledge of things is a perception of ideas that are in accordance or discordance with each other, which is very different from the quest for certainty of Descartes.

Now answer this question: What does 'tabula rasa' mean?

Output: blank tablet


Article: Meanwhile, producer Joe Pasternak, who had been successfully producing light musicals with young sopranos for Universal's German subsidiary, repeated his formula in America. Teenage singer Deanna Durbin starred in Pasternak's first American film, Three Smart Girls (1936). The film was a box-office hit and reputedly restored the studio's solvency. The success of the film led Universal to offer her a contract, which for the first five years of her career produced her most successful pictures.

Question: In what year was Three Smart Girls made?
Ans: 1936


Here is a question about this article: Victoria was physically unprepossessing—she was stout, dowdy and no more than five feet tall—but she succeeded in projecting a grand image. She experienced unpopularity during the first years of her widowhood, but was well liked during the 1880s and 1890s, when she embodied the empire as a benevolent matriarchal figure. Only after the release of her diary and letters did the extent of her political influence become known to the wider public. Biographies of Victoria written before much of the primary material became available, such as Lytton Strachey's Queen Victoria of 1921, are now considered out of date. The biographies written by Elizabeth Longford and Cecil Woodham-Smith, in 1964 and 1972 respectively, are still widely admired. They, and others, conclude that as a person Victoria was emotional, obstinate, honest, and straight-talking.
What is the answer to this question: What year did Cecil Woodham Smith writ Victorias biography?
****
So... 1972


The problem: Answer a question about this article:
John's personal life greatly affected his reign. Contemporary chroniclers state that John was sinfully lustful and lacking in piety. It was common for kings and nobles of the period to keep mistresses, but chroniclers complained that John's mistresses were married noblewomen, which was considered unacceptable. John had at least five children with mistresses during his first marriage to Isabelle of Gloucester, and two of those mistresses are known to have been noblewomen. John's behaviour after his second marriage to Isabella of Angoulême is less clear, however. None of John's known illegitimate children were born after he remarried, and there is no actual documentary proof of adultery after that point, although John certainly had female friends amongst the court throughout the period. The specific accusations made against John during the baronial revolts are now generally considered to have been invented for the purposes of justifying the revolt; nonetheless, most of John's contemporaries seem to have held a poor opinion of his sexual behaviour.[nb 14]
How many children did John have with mistresses during his first marriage?
****
The answer: five


The problem: Answer a question about this article:
In nature, the red color of blood comes from hemoglobin, the iron-containing protein found in the red blood cells of all vertebrates. The red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide. It also causes the red color of the planet Mars. The red sky at sunset and sunrise is caused by an optical effect known as Rayleigh scattering, which, when the sun is low or below the horizon, increases the red-wavelength light that reaches the eye. The color of autumn leaves is caused by pigments called anthocyanins, which are produced towards the end of summer, when the green chlorophyll is no longer produced. One to two percent of the human population has red hair; the color is produced by high levels of the reddish pigment pheomelanin (which also accounts for the red color of the lips) and relatively low levels of the dark pigment eumelanin.
Why does a sky turn red when the evening comes?

The answer:
Rayleigh scattering
