Question: Statistics from late 2003 indicate that Apple had 2.06 percent of the desktop share in the United States that had increased to 2.88 percent by Q4 2004. As of October 2006, research firms IDC and Gartner reported that Apple's market share in the U.S. had increased to about 6 percent. Figures from December 2006, showing a market share around 6 percent (IDC) and 6.1 percent (Gartner) are based on a more than 30 percent increase in unit sale from 2005 to 2006. The installed base of Mac computers is hard to determine, with numbers ranging from 5% (estimated in 2009) to 16% (estimated in 2005).
Is there an answer to this question: What percent of the desktop share in the U.S. did Apple have in 2004?

Answer: unanswerable


Question: 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.
Is there an answer to this question: What happened in 1893 that destroyed most of the mosaics in the mosque?

Answer: a fire


Question: Biographers Blundy and Lycett believed that he was "a populist at heart." Throughout Libya, crowds of supporters would turn up to public events at which he appeared; described as "spontaneous demonstrations" by the government, there are recorded instances of groups being coerced or paid to attend. He was typically late to public events, and would sometimes not show up at all. Although Bianco thought he had a "gift for oratory", he was considered a poor orator by biographers Blundy and Lycett. Biographer Daniel Kawczynski noted that Gaddafi was famed for his "lengthy, wandering" speeches, which typically involved criticising Israel and the U.S.
Is there an answer to this question: Who noted that Gaddafi made long speeches?

Answer: Daniel Kawczynski


Question: Freemasonry consists of fraternal organisations that trace their origins to the local fraternities of stonemasons, which from the end of the fourteenth century regulated the qualifications of stonemasons and their interaction with authorities and clients. The degrees of freemasonry retain the three grades of medieval craft guilds, those of Apprentice, Journeyman or fellow (now called Fellowcraft), and Master Mason. These are the degrees offered by Craft (or Blue Lodge) Freemasonry. Members of these organisations are known as Freemasons or Masons. There are additional degrees, which vary with locality and jurisdiction, and are usually administered by different bodies than the craft degrees.
Is there an answer to this question: What were the fraternities of stonemasons avoiding responsibility for?

Answer:
unanswerable
