Passage: In the 16th century, Count Hieronymus Schlick of Bohemia began minting coins known as Joachimstalers (from German thal, or nowadays usually Tal, "valley", cognate with "dale" in English), named for Joachimstal, the valley where the silver was mined (St. Joachim's Valley, now Jáchymov; then part of the Kingdom of Bohemia, now part of the Czech Republic). Joachimstaler was later shortened to the German Taler, a word that eventually found its way into Danish and Swedish as daler, Norwegian as dalar and daler, Dutch as daler or daalder, Ethiopian as ታላሪ (talari), Hungarian as tallér, Italian as tallero, and English as dollar. Alternatively, thaler is said to come from the German coin Guldengroschen ("great guilder", being of silver but equal in value to a gold guilder), minted from the silver from Joachimsthal. Question: Other than "taler", what is the other name of the German coin?
answer:
Guldengroschen

question:
Passage: The first military unit of the Ottoman State was an army that was organized by Osman I from the tribesmen inhabiting the hills of western Anatolia in the late 13th century. The military system became an intricate organization with the advance of the Empire. The Ottoman military was a complex system of recruiting and fief-holding. The main corps of the Ottoman Army included Janissary, Sipahi, Akıncı and Mehterân. The Ottoman army was once among the most advanced fighting forces in the world, being one of the first to use muskets and cannons. The Ottoman Turks began using falconets, which were short but wide cannons, during the Siege of Constantinople. The Ottoman cavalry depended on high speed and mobility rather than heavy armour, using bows and short swords on fast Turkoman and Arabian horses (progenitors of the Thoroughbred racing horse), and often applied tactics similar to those of the Mongol Empire, such as pretending to retreat while surrounding the enemy forces inside a crescent-shaped formation and then making the real attack. The decline in the army's performance became clear from the mid-17th century and after the Great Turkish War. The 18th century saw some limited success against Venice, but in the north the European-style Russian armies forced the Ottomans to concede land. Question: In what conflict did the Ottoman Turks use falconets?
answer:

Siege of Constantinople
