Input: Read this: In 2010, the literacy rate of Liberia was estimated at 60.8% (64.8% for males and 56.8% for females). In some areas primary and secondary education is free and compulsory from the ages of 6 to 16, though enforcement of attendance is lax. In other areas children are required to pay a tuition fee to attend school. On average, children attain 10 years of education (11 for boys and 8 for girls). The country's education sector is hampered by inadequate schools and supplies, as well as a lack of qualified teachers.
Question: How intense is the enforcement of school dress code?

Output: unanswerable

Input: Read this: Aristotle's explanation of how this was possible was not strictly empiricist in a modern sense, but rather based on his theory of potentiality and actuality, and experience of sense perceptions still requires the help of the active nous. These notions contrasted with Platonic notions of the human mind as an entity that pre-existed somewhere in the heavens, before being sent down to join a body on Earth (see Plato's Phaedo and Apology, as well as others). Aristotle was considered to give a more important position to sense perception than Plato, and commentators in the Middle Ages summarized one of his positions as "nihil in intellectu nisi prius fuerit in sensu" (Latin for "nothing in the intellect without first being in the senses").
Question: What position by Plato was summarized by Middle Ages commentators?

Output: unanswerable

Input: Read this: The Alaska Native Language Center at the University of Alaska Fairbanks claims that at least 20 Alaskan native languages exist and there are also some languages with different dialects. Most of Alaska's native languages belong to either the EskimoAleut or Na-Dene language families however some languages are thought to be isolates (e.g. Haida) or have not yet been classified (e.g. Tsimshianic). As of 2014[update] nearly all of Alaska's native languages were classified as either threatened, shifting, moribund, nearly extinct, or dormant languages.
Question: How many of Alaska's native languages are in danger of becoming dormant or extinct languages according to a 2015 study?

Output: unanswerable

Input: Read this: While the book was readable enough to sell, its dryness ensured that it was seen as aimed at specialist scientists and could not be dismissed as mere journalism or imaginative fiction. Unlike the still-popular Vestiges, it avoided the narrative style of the historical novel and cosmological speculation, though the closing sentence clearly hinted at cosmic progression. Darwin had long been immersed in the literary forms and practices of specialist science, and made effective use of his skills in structuring arguments. David Quammen has described the book as written in everyday language for a wide audience, but noted that Darwin's literary style was uneven: in some places he used convoluted sentences that are difficult to read, while in other places his writing was beautiful. Quammen advised that later editions were weakened by Darwin making concessions and adding details to address his critics, and recommended the first edition. James T. Costa said that because the book was an abstract produced in haste in response to Wallace's essay, it was more approachable than the big book on natural selection Darwin had been working on, which would have been encumbered by scholarly footnotes and much more technical detail. He added that some parts of Origin are dense, but other parts are almost lyrical, and the case studies and observations are presented in a narrative style unusual in serious scientific books, which broadened its audience.
Question: What element of On the Origin of Species ensured that the book would be taken seriously by scientists?

Output:
its dryness ensured that it was seen as aimed at specialist scientists and could not be dismissed as mere journalism or imaginative fiction.
