Problem: House music:

Chicago Mayor Richard M. Daley proclaimed August 10, 2005 to be "House Unity Day" in Chicago, in celebration of the "21st anniversary of house music" (actually the 21st anniversary of the founding of Trax Records, an independent Chicago-based house label). The proclamation recognized Chicago as the original home of house music and that the music's original creators "were inspired by the love of their city, with the dream that someday their music would spread a message of peace and unity throughout the world". DJs such as Frankie Knuckles, Marshall Jefferson, Paul Johnson and Mickey Oliver celebrated the proclamation at the Summer Dance Series, an event organized by Chicago's Department of Cultural Affairs.

Problem: In America, Episcopalian Dennis Bennett is sometimes cited as one of the charismatic movement's seminal influence. In the United Kingdom, Colin Urquhart, Michael Harper, David Watson and others were in the vanguard of similar developments. The Massey conference in New Zealand, 1964 was attended by several Anglicans, including the Rev. Ray Muller, who went on to invite Bennett to New Zealand in 1966, and played a leading role in developing and promoting the Life in the Spirit seminars. Other Charismatic movement leaders in New Zealand include Bill Subritzky.
What American is considered to have been a seminal influence in the charismatic movement?

Answer: Dennis Bennett

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Lossless audio compression produces a representation of digital data that decompress to an exact digital duplicate of the original audio stream, unlike playback from lossy compression techniques such as Vorbis and MP3. Compression ratios are around 5060% of original size, which is similar to those for generic lossless data compression. Lossless compression is unable to attain high compression ratios due to the complexity of waveforms and the rapid changes in sound forms. Codecs like FLAC, Shorten and TTA use linear prediction to estimate the spectrum of the signal. Many of these algorithms use convolution with the filter [-1 1] to slightly whiten or flatten the spectrum, thereby allowing traditional lossless compression to work more efficiently. The process is reversed upon decompression.
What are three Codecs that use linear prediction to estimate the decompression?
A: unanswerable

Context and question: In 1903 Hermann Emil Fischer and Joseph von Mering disclosed their discovery that diethylbarbituric acid, formed from the reaction of diethylmalonic acid, phosphorus oxychloride and urea, induces sleep in dogs. The discovery was patented and licensed to Bayer pharmaceuticals, which marketed the compound under the trade name Veronal as a sleep aid beginning in 1904. Systematic investigations of the effect of structural changes on potency and duration of action led to the discovery of phenobarbital at Bayer in 1911 and the discovery of its potent anti-epileptic activity in 1912. Phenobarbital was among the most widely used drugs for the treatment of epilepsy through the 1970s, and as of 2014, remains on the World Health Organizations list of essential medications. The 1950s and 1960s saw increased awareness of the addictive properties and abuse potential of barbiturates and amphetamines and led to increasing restrictions on their use and growing government oversight of prescribers. Today, amphetamine is largely restricted to use in the treatment of attention deficit disorder and phenobarbital in the treatment of epilepsy.
Why was barbiturates and amphetamines restricted?
Answer: addictive properties and abuse potential

Question: Royal assent is the final stage in the legislative process for acts of the Scottish parliament. The process is governed by sections 28, 32, and 33 of the Scotland Act 1998. After a bill has been passed, the Presiding Officer of the Scottish Parliament submits it to the monarch for royal assent after a four-week period, during which the Advocate General for Scotland, the Lord Advocate, the Attorney General or the Secretary of State for Scotland may refer the bill to the Supreme Court of the United Kingdom (prior to 1 October 2009, the Judicial Committee of the Privy Council) for review of its legality. Royal assent is signified by letters patent under the Great Seal of Scotland in the following form which is set out in The Scottish Parliament (Letters Patent and Proclamations) Order 1999 (SI 1999/737) and of which notice is published in the London, Edinburgh, and Belfast Gazettes:
Is there an answer to this question: In Scotland, who is responsible for submitting a bill for royal assent?

Answer: Presiding Officer of the Scottish Parliament

Question: During World War I, the palace, then the home of King George V and Queen Mary, escaped unscathed. Its more valuable contents were evacuated to Windsor but the royal family remained in situ. The King imposed rationing at the palace, much to the dismay of his guests and household. To the King's later regret, David Lloyd George persuaded him to go further by ostentatiously locking the wine cellars and refraining from alcohol, to set a good example to the supposedly inebriated working class. The workers continued to imbibe and the King was left unhappy at his enforced abstinence. In 1938, the north-west pavilion, designed by Nash as a conservatory, was converted into a swimming pool.
Is there an answer to this question: What year was the south-west pavilion turned into a swimming pool?

Answer:
unanswerable
