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.

Question: "What are the possible causes of the fire that broke out in the eastern palace of Xerxes?"

Alexander married twice: Roxana, daughter of the Bactrian nobleman Oxyartes, out of love; and Stateira II, a Persian princess and daughter of Darius III of Persia, for political reasons. He apparently had two sons, Alexander IV of Macedon of Roxana and, possibly, Heracles of Macedon from his mistress Barsine. He lost another child when Roxana miscarried at Babylon. Alexander also had a close relationship with his friend, general, and bodyguard Hephaestion, the son of a Macedonian noble. Hephaestion's death devastated Alexander. This event may have contributed to Alexander's failing health and detached mental state during his final months. Alexander's sexuality has been the subject of speculation and controversy. No ancient sources stated that Alexander had homosexual relationships, or that Alexander's relationship with Hephaestion was sexual. Aelian, however, writes of Alexander's visit to Troy where "Alexander garlanded the tomb of Achilles and Hephaestion that of Patroclus, the latter riddling that he was a beloved of Alexander, in just the same way as Patroclus was of Achilles". Noting that the word eromenos (ancient Greek for beloved) does not necessarily bear sexual meaning, Alexander may have been bisexual, which in his time was not controversial. Green argues that there is little evidence in ancient sources that Alexander had much carnal interest in women; he did not produce an heir until the very end of his life. However, he was relatively young when he died, and Ogden suggests that Alexander's matrimonial record is more impressive than his father's at the same age. Apart from wives, Alexander had many more female companions. Alexander accumulated a harem in the style of Persian kings, but he used it rather sparingly; showing great self-control in "pleasures of the body". Nevertheless, Plutarch described how Alexander was infatuated by Roxana while complimenting him on not forcing himself on her. Green suggested that, in the context of the period, Alexander formed quite strong friendships with women, including Ada of Caria, who adopted him, and even Darius's mother Sisygambis, who supposedly died from grief upon hearing of Alexander's death.

Problem: Simply put, energy is the ability to a cause change. Energy can cause many types of change. Think about when you have a lot of energy. You are able to do a lot of things. When you dont have a lot of energy, you may sit around and do very little. A similar thing happens to particles of matter as energy is added. The more energy there is, the faster the particles of matter move. Energy is also the reason you are able to move around. In fact, matter is always in motion. It can even change from one form to another. For example, electrical energy can be converted into heat energy. You see this every time you use the toaster. Energy causes a change in matter when you lift your arm. Energy can be used to move matter. You use energy to take a step to move forward. Thanks to energy, your body moves. The energy of moving matter is called kinetic energy.

Question: "What happens when someone has a lot of energy as compared to little energy?"

Answer: "Electrical energy"

On to the Twentieth Century: The British extended their control over the peninsula by putting together the whole panoply of colonial administrationcivil service, public works, judiciary force, police force, post office, education, and land regulationwith 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.
