Problem: Daylight saving time:

Start and end dates vary with location and year. Since 1996 European Summer Time has been observed from the last Sunday in March to the last Sunday in October; previously the rules were not uniform across the European Union. Starting in 2007, most of the United States and Canada observe DST from the second Sunday in March to the first Sunday in November, almost two-thirds of the year. The 2007 US change was part of the Energy Policy Act of 2005; previously, from 1987 through 2006, the start and end dates were the first Sunday in April and the last Sunday in October, and Congress retains the right to go back to the previous dates now that an energy-consumption study has been done. Proponents for permanently retaining November as the month for ending DST point to Halloween as a reason to delay the change in order to allow extra daylight for the evening of October 31.

What government body is allowed to change the DST policy in the United States back to the dates observed from 1987 to 2006?

A: Congress

Problem: The proper recitation of the Quran is the subject of a separate discipline named tajwid which determines in detail how the Quran should be recited, how each individual syllable is to be pronounced, the need to pay attention to the places where there should be a pause, to elisions, where the pronunciation should be long or short, where letters should be sounded together and where they should be kept separate, etc. It may be said that this discipline studies the laws and methods of the proper recitation of the Quran and covers three main areas: the proper pronunciation of consonants and vowels (the articulation of the Quranic phonemes), the rules of pause in recitation and of resumption of recitation, and the musical and melodious features of recitation.
What discipline concerns the way the Quran is correctly unrecited?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Armenian literature dates back to 400 AD, when Mesrop Mashtots first invented the Armenian alphabet. This period of time is often viewed as the Golden Age of Armenian literature. Early Armenian literature was written by the "father of Armenian history", Moses of Chorene, who authored The History of Armenia. The book covers the time-frame from the formation of the Armenian people to the fifth century AD. The nineteenth century beheld a great literary movement that was to give rise to modern Armenian literature. This period of time, during which Armenian culture flourished, is known as the Revival period (Zartonki sherchan). The Revivalist authors of Constantinople and Tiflis, almost identical to the Romanticists of Europe, were interested in encouraging Armenian nationalism. Most of them adopted the newly created Eastern or Western variants of the Armenian language depending on the targeted audience, and preferred them over classical Armenian (grabar). This period ended after the Hamidian massacres, when Armenians experienced turbulent times. As Armenian history of the 1920s and of the Genocide came to be more openly discussed, writers like Paruyr Sevak, Gevork Emin, Silva Kaputikyan and Hovhannes Shiraz began a new era of literature.
What work was written by Silva Kaputikyan?
A: unanswerable

Context and question: Avicenna was a devout Muslim and sought to reconcile rational philosophy with Islamic theology. His aim was to prove the existence of God and His creation of the world scientifically and through reason and logic. Avicenna's views on Islamic theology (and philosophy) were enormously influential, forming part of the core of the curriculum at Islamic religious schools until the 19th century. Avicenna wrote a number of short treatises dealing with Islamic theology. These included treatises on the prophets (whom he viewed as "inspired philosophers"), and also on various scientific and philosophical interpretations of the Quran, such as how Quranic cosmology corresponds to his own philosophical system. In general these treatises linked his philosophical writings to Islamic religious ideas; for example, the body's afterlife.
Up until what century was Avicenna's work slightly influential?
Answer: unanswerable

Question: Napoleon's coronation took place on December 2, 1804. Two separate crowns were brought for the ceremony: a golden laurel wreath recalling the Roman Empire and a replica of Charlemagne's crown. Napoleon entered the ceremony wearing the laurel wreath and kept it on his head throughout the proceedings. For the official coronation, he raised the Charlemagne crown over his own head in a symbolic gesture, but never placed it on top because he was already wearing the golden wreath. Instead he placed the crown on Josephine's head, the event commemorated in the officially sanctioned painting by Jacques-Louis David. Napoleon was also crowned King of Italy, with the Iron Crown of Lombardy, at the Cathedral of Milan on May 26, 1805. He created eighteen Marshals of the Empire from amongst his top generals to secure the allegiance of the army.
Is there an answer to this question: On what date did Napoleon's coronation occur?

Answer: December 2, 1804

Question: As many Japanese had feared, Japan's supply arrangements could not maintain her forces. Once Mutaguchi's hopes for an early victory were thwarted, his troops, particularly those at Kohima, starved. During May, while Mutaguchi continued to order attacks, the Allies advanced southwards from Kohima and northwards from Imphal. The two Allied attacks met on 22 June, breaking the Japanese siege of Imphal. The Japanese finally broke off the operation on 3 July. They had lost over 50,000 troops, mainly to starvation and disease. This represented the worst defeat suffered by the Japanese Army to that date.[citation needed]
Is there an answer to this question: How many troops had the Japanese lost?

Answer:
50,000
