Question: Unicode has become the dominant scheme for internal processing and storage of text. Although a great deal of text is still stored in legacy encodings, Unicode is used almost exclusively for building new information processing systems. Early adopters tended to use UCS-2 (the fixed-width two-byte precursor to UTF-16) and later moved to UTF-16 (the variable-width current standard), as this was the least disruptive way to add support for non-BMP characters. The best known such system is Windows NT (and its descendants, Windows 2000, Windows XP, Windows Vista and Windows 7), which uses UTF-16 as the sole internal character encoding. The Java and .NET bytecode environments, Mac OS X, and KDE also use it for internal representation. Unicode is available on Windows 95 through Microsoft Layer for Unicode, as well as on its descendants, Windows 98 and Windows ME.
Is there an answer to this question: What is the dominant scheme for internal processing?

Answer: Unicode

Question: A week after the implementation of the no-fly zone, NATO announced that it would be enforced.

Question: A variation of the incandescent lamp did not use a hot wire filament, but instead used an arc struck on a spherical bead electrode to produce heat. The electrode then became incandescent, with the arc contributing little to the light produced. Such lamps were used for projection or illumination for scientific instruments such as microscopes. These arc lamps ran on relatively low voltages and incorporated tungsten filaments to start ionization within the envelope. They provided the intense concentrated light of an arc lamp but were easier to operate. Developed around 1915, these lamps were displaced by mercury and xenon arc lamps.
Is there an answer to this question: What type of lamp used a hot wire filament?

Answer: unanswerable

Question: On 1 February 1908, the king Dom Carlos I of Portugal and his heir apparent, Prince Royal Dom Luis Filipe, Duke of Braganza, were murdered in Lisbon. Under his rule, Portugal had twice been declared bankrupt on 14 June 1892, and again on 10 May 1902 causing social turmoil, economic disturbances, protests, revolts and criticism of the monarchy. Manuel II of Portugal became the new king, but was eventually overthrown by the 5 October 1910 revolution, which abolished the regime and instated republicanism in Portugal. Political instability and economic weaknesses were fertile ground for chaos and unrest during the Portuguese First Republic. These conditions would lead to the failed Monarchy of the North, 28 May 1926 coup d'etat, and the creation of the National Dictatorship (Ditadura Nacional).
Is there an answer to this question: On what day were King Dom Carlos I and and his heir, Prince Royal Dom Luis Filipe, Duke of Braganza, murdered?

Answer:
1 February 1908
