By the Middle Ages, large numbers of Jews lived in the Holy Roman Empire and had assimilated into German culture, including many Jews who had previously assimilated into French culture and had spoken a mixed Judeo-French language. Upon assimilating into German culture, the Jewish German peoples incorporated major parts of the German language and elements of other European languages into a mixed language known as Yiddish. However tolerance and assimilation of Jews in German society suddenly ended during the Crusades with many Jews being forcefully expelled from Germany and Western Yiddish disappeared as a language in Germany over the centuries, with German Jewish people fully adopting the German language.
Where was Yiddish spoken after the Crusades?

In southern Europe, a Catholic coalition led by Philip II of Spain won a victory over the Ottoman fleet at the Battle of Lepanto (1571). It was a startling, if mostly symbolic, blow to the image of Ottoman invincibility, an image which the victory of the Knights of Malta against the Ottoman invaders in the 1565 Siege of Malta had recently set about eroding. The battle was far more damaging to the Ottoman navy in sapping experienced manpower than the loss of ships, which were rapidly replaced. The Ottoman navy recovered quickly, persuading Venice to sign a peace treaty in 1573, allowing the Ottomans to expand and consolidate their position in North Africa.
What battle did the Spanish win in 1571?
A: Battle of Lepanto

To be considered 'enriched', the uranium-235 fraction should be between 3% and 5%. This process produces huge quantities of uranium that is depleted of uranium-235 and with a correspondingly increased fraction of uranium-238, called depleted uranium or 'DU'. To be considered 'depleted', the uranium-235 isotope concentration should be no more than 0.3%. The price of uranium has risen since 2001, so enrichment tailings containing more than 0.35% uranium-235 are being considered for re-enrichment, driving the price of depleted uranium hexafluoride above $130 per kilogram in July 2007 from $5 in 2001.
What was the price of a pound of depleted uranium hexafluoride in 2001?
A:
unanswerable
