Q: Question: When did the Sassanids replace the Parthians? Passage:In 270 the Roman emperor Aurelian engaged the Sassanids, who had now replaced the Parthians, on the eastern front and he was able to drive them back. Tiridates, as the true heir to the now Persian-occupied Armenian throne, came to Armenia and quickly raised an army and drove the enemy out in 287. When Tiridates returned to Armenia, he made the city of Vagharshapat his capital, as it had been the capital of his late father. For a while, fortune appeared to favour Tiridates. He not only expelled his enemies, but he carried his arms into Assyria. At the time the Persian Empire was in a distracted state. The throne was disputed by the ambition of two contending brothers, Hormuz and Narses. The civil war was, however, soon terminated and Narses was universally acknowledged as King of Persia. Narses then directed his whole force against the foreign enemy. The contest then became too unequal. Tiridates once more took refuge with the Romans. The Roman-Armenian alliance grew stronger, especially while Diocletian ruled the empire. This can be attributed to the upbringing of Tiridates, the consistent Persian aggressions and the murder of his father by Anak. With Diocletian's help, Tiridates pushed the Persians out of Armenia. In 299, Diocletian left the Armenian state in a quasi-independent and protectorate status possibly to use it as a buffer in case of a Persian attack. Tiridates married an Alani Princess called Ashkhen in 297 by whom he had three children: a son called Khosrov III, a daughter called Salome and an unnamed daughter who married St. Husik I, one of the earlier Catholicoi of the Armenian Apostolic Church.

Q: Question: Was Hirohito an adult when the San Francisco Peace Treaty was signed? Passage:The Allied occupation of Japan at the end of World War II was led by General Douglas MacArthur, the Supreme Commander of the Allied Powers, with support from the British Commonwealth. Unlike in the occupation of Germany, the Soviet Union was allowed little to no influence over Japan. This foreign presence marks the only time in Japan's history that it has been occupied by a foreign power. At MacArthur's insistence, Emperor Hirohito remained on the imperial throne. The wartime cabinet was replaced with a cabinet acceptable to the Allies and committed to implementing the terms of the Potsdam Declaration, which among other things called for the country to become a parliamentary democracy. Under MacArthur's guidance, the Japanese government introduced sweeping social reforms and implemented economic reforms that recalled American "New Deal" priorities of the 1930s under President Roosevelt. The Japanese constitution was comprehensively overhauled and the Emperor's theoretically-vast powers, which for many centuries had been constrained by conventions that had evolved over time, became strictly limited by law. The occupation, codenamed Operation Blacklist, was ended by the San Francisco Peace Treaty, signed on September 8, 1951, and effective from April 28, 1952, after which Japan's sovereigntywith the exception, until 1972, of the Ryukyu Islands was fully restored.

Q: Question: Which admiral commanded more ships, Osborn or La Clue? Passage:By October 1757 Rowley had been given the task of commissioning the 60-gun fourth-rate . Once launched she joined Admiral Henry Osborn’s fleet of 14 ships of the line in the Mediterranean. Osborn was at the time blockading the French under Admiral La Clue in the Spanish city of Cartagena preventing them from joining the fleet off Louisburg in Nova Scotia. French command had ordered the Marquis Duquesne to break through the British blockade and reinforce La Clue and then with superiority of numbers break out of Cartagena and make their way to America. Osborn intercepted Duquesne and his three ships of the line and one frigate. The subsequent action became known as the Battle of Cartagena and took place on 28 February 1758. Osborn's squadron captured two of the French line of battle ships and, under the guns of the Spanish castle the 60-gun French Oriflamme was driven on shore by the Montagu and the . Whilst the battle was not particularly grand the annihilation of the forces under Duquesne had two distinct effects. Firstly, the battle restored much of the pride that had been sapped from the navy after several defeats including those at Toulon and Minorca. Secondly, the siege of Louisburg and its surrender led to the French being marginalised as a significant power in North America. The battle can therefore be considered by the British as one of the defining achievements of the Seven Years' War. Had La Clue managed to break out from Osborn's close blockade the modern map of North America might appear quite different.
