Problem: Please answer a question about the following article about Seven Years%27 War:
Despite this, the Austrians, under the command of General Laudon, captured Glatz (now Kłodzko, Poland) in Silesia. In the Battle of Liegnitz Frederick scored a strong victory despite being outnumbered three to one. The Russians under General Saltykov and Austrians under General Lacy briefly occupied his capital, Berlin, in October, but could not hold it for long. The end of that year saw Frederick once more victorious, defeating the able Daun in the Battle of Torgau; but he suffered very heavy casualties, and the Austrians retreated in good order.
Why was Frederick's defeat of Daun so costly?
A: he suffered very heavy casualties, and the Austrians retreated in good order.
Problem: Please answer a question about the following article about Middle Ages:
Jewish communities were expelled from England in 1290 and from France in 1306. Although some were allowed back into France, most were not, and many Jews emigrated eastwards, settling in Poland and Hungary. The Jews were expelled from Spain in 1492, and dispersed to Turkey, France, Italy, and Holland. The rise of banking in Italy during the 13th century continued throughout the 14th century, fuelled partly by the increasing warfare of the period and the needs of the papacy to move money between kingdoms. Many banking firms loaned money to royalty, at great risk, as some were bankrupted when kings defaulted on their loans.[AE]
Along with Hungary, where did many expelled French Jews relocate to?
A: Poland
Problem: Please answer a question about the following article about MP3:
A more sophisticated MP3 encoder can produce variable bitrate audio. MPEG audio may use bitrate switching on a per-frame basis, but only layer III decoders must support it. VBR is used when the goal is to achieve a fixed level of quality. The final file size of a VBR encoding is less predictable than with constant bitrate. Average bitrate is VBR implemented as a compromise between the two: the bitrate is allowed to vary for more consistent quality, but is controlled to remain near an average value chosen by the user, for predictable file sizes. Although an MP3 decoder must support VBR to be standards compliant, historically some decoders have bugs with VBR decoding, particularly before VBR encoders became widespread.
Which type of decoder must support bitrate switching on a per-frame basis?
A: layer III
Problem: Please answer a question about the following article about British Empire:
In 1869 the Suez Canal opened under Napoleon III, linking the Mediterranean with the Indian Ocean. Initially the Canal was opposed by the British; but once opened, its strategic value was quickly recognised and became the "jugular vein of the Empire". In 1875, the Conservative government of Benjamin Disraeli bought the indebted Egyptian ruler Isma'il Pasha's 44 percent shareholding in the Suez Canal for £4 million (£340 million in 2013). Although this did not grant outright control of the strategic waterway, it did give Britain leverage. Joint Anglo-French financial control over Egypt ended in outright British occupation in 1882. The French were still majority shareholders and attempted to weaken the British position, but a compromise was reached with the 1888 Convention of Constantinople, which made the Canal officially neutral territory.
Which French leader ruled when the Suez Canal opened?
A:
Napoleon III
