Question: Though prehistoric remains from the Paleolithic, Neolithic, and Bronze Ages have been unearthed in the Manzanares Valley, prior to Madrid's sudden elevation to capital city in 1561 its history was rather undistinguished. Over a period of many centuries crucial in Spanish history, Madrid's significance was negligible. The Romans built their most advanced outpost on the Iberian peninsula, but left nothing of consequence in Madrid. Armies of North African nomads, intent on disseminating Islam, invaded the peninsula in a.d. Within 10 years, they had overrun most of Spain. If Madrid played any role in these pivotal events, no record of it remains. The first solid references to this obscure settlement on the Castilian plateau, guarded by the looming Guadarrama mountain range, appear in the 9th century. The Arabic name for "place of many springs," variously recorded as Magerit, Mayrit or Magrit, eventually evolved into Madrid. The hamlet entered historical chronicles for its military significance; it was located near the main line of resistance to the Christian reconquest. Over centuries of struggle, the defending Moorish army built a full-scale fort, or Alcazar, on the heights of Madrid commanding the Manzanares valley. After several unsuccessful skirmishes, the Christian forces of Alfonso VI captured Madrid in 1083. The Alcazar became a fort of the crown of Castile. During a counter-offensive in 1109, the town was overrun by the Moors, but the Christianized fortress held. The Moors were expelled from the town, but they remained in control of southern Spain for almost four centuries. Meanwhile, Madrid enjoyed brief prominence in 1308 when king Ferdinand IV and his Cortes, an early version of parliament, held a formal meeting in the fledgling town. From then on, the kings of Spain began to visit Madrid, where the air was invigorating and the hunting excellent. Ferdinand and Isabella, the Catholic monarchs that united all the provinces of Spain, first visited Madrid in 1477. <sep>Why did kings of Spain visit Madrid?<sep>Women

Answer: No

Question: During this time, Alexander adopted some elements of Persian dress and customs at his court, notably the custom of proskynesis, either a symbolic kissing of the hand, or prostration on the ground, that Persians showed to their social superiors. The Greeks regarded the gesture as the province of deities and believed that Alexander meant to deify himself by requiring it. This cost him the sympathies of many of his countrymen, and he eventually abandoned it. A plot against his life was revealed, and one of his officers, Philotas, was executed for failing to alert Alexander. The death of the son necessitated the death of the father, and thus Parmenion, who had been charged with guarding the treasury at Ecbatana, was assassinated at Alexander's command, to prevent attempts at vengeance. Most infamously, Alexander personally killed the man who had saved his life at Granicus, Cleitus the Black, during a violent drunken altercation at Maracanda (modern day Samarkand in Uzbekistan), in which Cleitus accused Alexander of several judgemental mistakes and most especially, of having forgotten the Macedonian ways in favour of a corrupt oriental lifestyle. Later, in the Central Asian campaign, a second plot against his life was revealed, this one instigated by his own royal pages. His official historian, Callisthenes of Olynthus, was implicated in the plot; however, historians have yet to reach a consensus regarding this involvement. Callisthenes had fallen out of favor by leading the opposition to the attempt to introduce proskynesis. <sep>Who lost their lives when a plot against Alexander's life was revealed?<sep>Cleitus the Black

Answer: No

Question: The day was just breaking, as I left the tower; though it was still too dark in the house to be able to see without a light, and I took one of the study candles with me on my 'round. By the time I had finished the ground floor, the daylight was creeping in, wanly, through the barred windows. My search had shown me nothing fresh. Everything appeared to be in order, and I was on the point of extinguishing my candle, when the thought suggested itself to me to have another glance 'round the cellars. I had not, if I remember rightly, been into them since my hasty search on the evening of the attack. For, perhaps, the half of a minute, I hesitated. I would have been very willing to forego the task--as, indeed, I am inclined to think any man well might--for of all the great, awe-inspiring rooms in this house, the cellars are the hugest and weirdest. Great, gloomy caverns of places, unlit by any ray of daylight. Yet, I would not shirk the work. I felt that to do so would smack of sheer cowardice. Besides, as I reassured myself, the cellars were really the most unlikely places in which to come across anything dangerous; considering that they can be entered, only through a heavy oaken door, the key of which, I carry always on my person. <sep>Name two reasons the person chose to do a round of the cellars.<sep>To come across something dangerous, to look for his key
