Input: Read this: The theoretical difficulties arise from the fact that all of the methods except the X-ray crystal density method rely on the theoretical basis of the Josephson effect and the quantum Hall effect. If these theories are slightly inaccurate though there is no evidence at present to suggest they are the methods would not give accurate values for the Planck constant. More importantly, the values of the Planck constant obtained in this way cannot be used as tests of the theories without falling into a circular argument. Fortunately, there are other statistical ways of testing the theories, and the theories have yet to be refuted.
Question: Why does relying on these effects create concern?

Output: If these theories are slightly inaccurate

QUES: Production capacity in Britain and the United States was improved by the invention of the cotton gin by the American Eli Whitney in 1793. Before the development of cotton gins, the cotton fibers had to be pulled from the seeds tediously by hand. By the late 1700s a number of crude ginning machines had been developed. However, to produce a bale of cotton required over 600 hours of human labor, making large-scale production uneconomical in the United States, even with the use of humans as slave labor. The gin that Whitney manufactured (the Holmes design) reduced the hours down to just a dozen or so per bale. Although Whitney patented his own design for a cotton gin, he manufactured a prior design from Henry Odgen Holmes, for which Holmes filed a patent in 1796. Improving technology and increasing control of world markets allowed British traders to develop a commercial chain in which raw cotton fibers were (at first) purchased from colonial plantations, processed into cotton cloth in the mills of Lancashire, and then exported on British ships to captive colonial markets in West Africa, India, and China (via Shanghai and Hong Kong).

QUES: In some countries, the personal copying exemption explicitly requires that the content being copied was obtained legitimately i.e., from authorized sources, not file-sharing networks. Other countries, such as the Netherlands, make no such distinction; the exemption there had been assumed, even by the government, to apply to any such copying, even from file-sharing networks. However, in April 2014, the Court of Justice of the European Union ruled that "national legislation which makes no distinction between private copies made from lawful sources and those made from counterfeited or pirated sources cannot be tolerated." Thus, in the Netherlands, for example, downloading from file-sharing networks is no longer legal.
What is an example of a country that the exemption was assumed?

ANS: Netherlands

According to a 2011 Pew Research Center survey, there were 2.2 billion Christians around the world in 2010, up from about 600 million in 1910. By 2050, the Christian population is expected to exceed 3 billion. According to a 2012 Pew Research Center survey Christianity will remain the world's largest religion in 2050, if current trends continue.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which survey conducted in 2012, concluded there were about 2.2 billion Christians worldwide?
Ah, so.. unanswerable

Question: There have been modern studies that have supported the original autopsy finding. In a 2008 study, researchers analysed samples of Napoleon's hair from throughout his life, as well as samples from his family and other contemporaries. All samples had high levels of arsenic, approximately 100 times higher than the current average. According to these researchers, Napoleon's body was already heavily contaminated with arsenic as a boy, and the high arsenic concentration in his hair was not caused by intentional poisoning; people were constantly exposed to arsenic from glues and dyes throughout their lives.[note 7] Studies published in 2007 and 2008 dismissed evidence of arsenic poisoning, and confirmed evidence of peptic ulcer and gastric cancer as the cause of death.
Try to answer this question if possible: Studies published in 2007 and 2008 support what possible causes of Napoleon's death?
Answer: peptic ulcer and gastric cancer

Input: Read this: Italy is home to a vast array of native regional minority languages, most of which are Romance-based and have their own local variants. These regional languages are often referred to colloquially or in non-linguistic circles as Italian "dialects," or dialetti (standard Italian for "dialects"). However, the majority of the regional languages in Italy are in fact not actually "dialects" of standard Italian in the strict linguistic sense, as they are not derived from modern standard Italian but instead evolved locally from Vulgar Latin independent of standard Italian, with little to no influence from what is now known as "standard Italian." They are therefore better classified as individual languages rather than "dialects."
Question: What does 'dialetti' mean in Italian?

Output:
dialects
