Question: Passage: The other Ancient Greek dialects, Ionic, Doric, Aeolic, and Arcadocypriot, likely had the same three-way distinction at one point, but Doric seems to have had a fricative in place of /tʰ/ in the Classical period, and the Ionic and Aeolic dialects sometimes lost aspiration (psilosis).

Answer: What ancient dialects had the same two-way distinction at one point?


Question: Passage: Australian citizens and residents from other parts of the nation now have automatic right of residence on the island after meeting these criteria (Immigration (Amendment No. 2) Act 2012). Australian citizens must carry either a passport or a Document of Identity to travel to Norfolk Island. Citizens of all other nations must carry a passport to travel to Norfolk Island even if arriving from other parts of Australia. Holders of Australian visas who travel to Norfolk Island have departed the Australian Migration Zone. Unless they hold a multiple-entry visa, the visa will have ceased; in which case they will require another visa to re-enter mainland Australia.

Answer: What automatic right do Australian citizens and residents lose on Norfolk Island after meeting the criteria in Immigration (Amendment No. 2) Act 2012?


Question: Passage: King Matthias Corvinus of Hungary (1458–1490) was one of the most prominent figures of the period, directing campaigns to the West, conquering Bohemia in answer to the Pope's call for help against the Hussite Protestants. Also, in resolving political hostilities with the German emperor Frederick III of Habsburg, he invaded his western domains. Matthew organized the Black Army of mercenary soldiers; it was considered as the biggest army of its time. Using this powerful tool, the Hungarian king led wars against the Turkish armies and stopped the Ottomans during his reign. After the death of Matthew, and with end of the Black Army, the Ottoman Empire grew in strength and Central Europe was defenseless. At the Battle of Mohács, the forces of the Ottoman Empire annihilated the Hungarian army and Louis II of Hungary drowned in the Csele Creek while trying to escape. The leader of the Hungarian army, Pál Tomori, also died in the battle. This is considered to be one of the final battles of Medieval times.

Answer:
How did Louis XII of Hungary die?
