The problem: Answer a question about this article:
The most important early Islamic mosaic work is the decoration of the Umayyad Mosque in Damascus, then capital of the Arab Caliphate. The mosque was built between 706 and 715. The caliph obtained 200 skilled workers from the Byzantine Emperor to decorate the building. This is evidenced by the partly Byzantine style of the decoration. The mosaics of the inner courtyard depict Paradise with beautiful trees, flowers and small hill towns and villages in the background. The mosaics include no human figures, which makes them different from the otherwise similar contemporary Byzantine works. The biggest continuous section survives under the western arcade of the courtyard, called the "Barada Panel" after the river Barada. It is thought that the mosque used to have the largest gold mosaic in the world, at over 4 m2. In 1893 a fire damaged the mosque extensively, and many mosaics were lost, although some have been restored since.
What happened in 1893 that destroyed most of the mosaics in the mosque?
****
The answer: a fire


Problem: Please answer a question about the following article about Solar energy:
Shuman built the world’s first solar thermal power station in Maadi, Egypt, between 1912 and 1913. Shuman’s plant used parabolic troughs to power a 45–52 kilowatts (60–70 hp) engine that pumped more than 22,000 litres (4,800 imp gal; 5,800 US gal) of water per minute from the Nile River to adjacent cotton fields. Although the outbreak of World War I and the discovery of cheap oil in the 1930s discouraged the advancement of solar energy, Shuman’s vision and basic design were resurrected in the 1970s with a new wave of interest in solar thermal energy. In 1916 Shuman was quoted in the media advocating solar energy's utilization, saying:
Where was the first solar thermal power plant built?
A: Maadi, Egypt

The Council of Trent approved a plan in 1563 for correcting the calendrical errors, requiring that the date of the vernal equinox be restored to that which it held at the time of the First Council of Nicaea in 325 and that an alteration to the calendar be designed to prevent future drift. This would allow for a more consistent and accurate scheduling of the feast of Easter. In 1577, a Compendium was sent to expert mathematicians outside the reform commission for comments. Some of these experts, including Giambattista Benedetti and Giuseppe Moleto, believed Easter should be computed from the true motions of the sun and moon, rather than using a tabular method, but these recommendations were not adopted. The reform adopted was a modification of a proposal made by the Calabrian doctor Aloysius Lilius (or Lilio).

What method was used instead of computations of the sun and moon?
Answer: tabular method


Problem: Antarctic explorers Robert Falcon Scott and Frank Bickerton both lived in the city. Artists include Beryl Cook whose paintings depict the culture of Plymouth and Robert Lenkiewicz, whose paintings investigated themes of vagrancy, sexual behaviour and suicide, lived in the city from the 1960s until his death in 2002. Illustrator and creator of children's series Mr Benn and King Rollo, David McKee, was born and brought up in South Devon and trained at Plymouth College of Art. Jazz musician John Surman, born in nearby Tavistock, has close connections to the area, evidenced by his 2012 album Saltash Bells. The avant garde prepared guitarist Keith Rowe was born in the city before establishing the jazz free improvisation band AMM in London in 1965 and MIMEO in 1997. The musician and film director Cosmo Jarvis has lived in several towns in South Devon and has filmed videos in and around Plymouth. In addition, actors Sir Donald Sinden and Judi Trott. George Passmore of Turner Prize winning duo Gilbert and George was born in the city, as was Labour politician Michael Foot whose family reside at nearby Trematon Castle.
What local figure played in the bands AMM and MIMEO?
The answer is the following: Keith Rowe


On 30 September, Zhou Enlai warned the United States that China was prepared to intervene in Korea if the United States crossed the 38th parallel. Zhou attempted to advise North Korean commanders on how to conduct a general withdrawal by using the same tactics which had allowed Chinese communist forces to successfully escape Chiang Kai-shek's Encirclement Campaigns in the 1930s, but by some accounts North Korean commanders did not utilize these tactics effectively. Historian Bruce Cumings argues, however, the KPA's rapid withdrawal was strategic, with troops melting into the mountains from where they could launch guerrilla raids on the UN forces spread out on the coasts.
Who believes that the North Koreans only appeared to fail to effective execute their withdrawal plan?
Bruce Cumings


Here is a question about this article: In 1880, Bell received the Volta Prize with a purse of 50,000 francs (approximately US$250,000 in today's dollars) for the invention of the telephone from the Académie française, representing the French government. Among the luminaries who judged were Victor Hugo and Alexandre Dumas. The Volta Prize was conceived by Napoleon Bonaparte in 1801, and named in honor of Alessandro Volta, with Bell receiving the third grand prize in its history. Since Bell was becoming increasingly affluent, he used his prize money to create endowment funds (the 'Volta Fund') and institutions in and around the United States capital of Washington, D.C.. These included the prestigious 'Volta Laboratory Association' (1880), also known as the Volta Laboratory and as the 'Alexander Graham Bell Laboratory', and which eventually led to the Volta Bureau (1887) as a center for studies on deafness which is still in operation in Georgetown, Washington, D.C. The Volta Laboratory became an experimental facility devoted to scientific discovery, and the very next year it improved Edison's phonograph by substituting wax for tinfoil as the recording medium and incising the recording rather than indenting it, key upgrades that Edison himself later adopted. The laboratory was also the site where he and his associate invented his "proudest achievement", "the photophone", the "optical telephone" which presaged fibre optical telecommunications, while the Volta Bureau would later evolve into the Alexander Graham Bell Association for the Deaf and Hard of Hearing (the AG Bell), a leading center for the research and pedagogy of deafness.
What is the answer to this question: Who first established the Volta Prize?
****
So...
Napoleon Bonaparte
