Input: Consider Input: From Babylon, Alexander went to Susa, one of the Achaemenid capitals, and captured its legendary treasury. He sent the bulk of his army to the Persian ceremonial capital of Persepolis via the Royal Road. Alexander himself took selected troops on the direct route to the city. He had to storm the pass of the Persian Gates (in the modern Zagros Mountains) which had been blocked by a Persian army under Ariobarzanes and then hurried to Persepolis before its garrison could loot the treasury. On entering Persepolis, Alexander allowed his troops to loot the city for several days. Alexander stayed in Persepolis for five months. During his stay a fire broke out in the eastern palace of Xerxes and spread to the rest of the city. Possible causes include a drunken accident or deliberate revenge for the burning of the Acropolis of Athens during the Second Persian War. <sep>What are the possible causes of the fire that broke out in the eastern palace of Xerxes?<sep>War

Output: No


Input: Consider Input: On to the Twentieth Century: The British extended their control over the peninsula by putting together the whole panoply of colonial administration — civil service, public works, judiciary force, police force, post office, education, and land regulation — with teams of British administrators, teachers, engineers, and doctors to go with it. At the same time, the tin industry, dominated by Chinese using labor-intensive methods in the 19th century, passed increasingly into Western hands, who employed the modern technology of gravel pumps and mining dredges. Petroleum had been found in northern Borneo, at Miri, and in Brunei, and the Anglo-Dutch Shell company used Singapore as its regional depot for its oil supplies and exports. But the major breakthrough for the Malay economy was the triumph of rubber, when Singapore's new garden director, Henry Ridle ("Rubber Ridley" to his friends, "Mad Ridley" to all doubting Thomases) had developed new planting and tapping methods and painstakingly spread his faith in rubber around the peninsula. World demand increased with the growth of the motor-car and electrical industries, and sky-rocketed during World War I. By 1920, Malaya was producing 53 percent of the world's rubber, which had overtaken tin as its main source of income. The Malay ruling class again took a back seat. Together with effective control of the rubber and tin industries, the British now firmly held the reins of government. The sultans were left in charge of local and religious affairs, content with their prestige, prosperity, and security. The census of 1931 served as an alarm signal for the Malay national consciousness. Bolstered by a new influx of immigrants to meet the rubber and tin booms of the 1920s, non-Malays now slightly outnumbered the indigenous population. The Great Depression of 1929 stepped up ethnic competition in the shrinking job market, and nationalism developed to safeguard Malay interests against the Chinese and Indians rather than the British imperial authority. Though hampered by the peninsula's division into the States and the Straits Settlements, relatively conservative Muslim intellectuals and community leaders came together at the Pan-Malayan Malay Congress in Kuala Lumpur in 1939. In Singapore the following year, they were joined by representatives from Sarawak and Brunei. Teachers and journalists urged the revival of the common Malay-Indonesian consciousness, split by the Anglo-Dutch dismemberment of the region in the 19th century. This spirit became a factor in the gathering clouds of war. <sep>What caused the Malay ruling class to take a back seat?<sep>Auto and electrical industry demand for rubber, which dramatically increased during World War I

Output: Yes


Input: Consider Input: Crusaders, Mamelukes, and Turks: The Crusaders established a feudal Christian state with Godfrey at its head. They built many impressive churches during the term of the first Latin Kingdom of Jerusalem, but in 1187 they were driven out by Muslim forces under the great warrior Saladin. During the Sixth Crusade (1228– 1229), the Holy Roman Emperor Frederick II managed to secure Jerusalem for the Christians by negotiation. The Christians, however, could not hold the city. After they lost Jerusalem, a Mongol invasion swept through, and in 1244 the Mameluke dynasty of Egypt took control, ruling Jerusalem for the next 250 years. The city struggled to rebuild from Crusader wars and invasions. Much of the best Islamic architecture in the city was constructed in the Mameluke era, but the past thousand years had taken their toll: Jerusalem was unable to regain the prosperity it had enjoyed in earlier times. In the early 16th century, the Ottoman Turkish Empire was advancing through the Middle East. Jerusalem fell to the Ottomans in 1517, remaining under their control for 400 years. Suleiman the Magnificent rebuilt the walls and gates in the form they retain to this day. Fountains, inns, religious schools, and barracks were constructed. But when Suleiman died, his empire, including Jerusalem, began a long period of decline. The Holy City remained a backwater until the 19th century, when renewed interest among Christian pilgrims made it the destination of thousands of travelers each year. <sep>Who ruled Jerusalem at some point?<sep>Muslims


Output: Yes
