Input: As food is pushed along, it undergoes digestion. Digestion is the process of breaking down food into nutrients. There are two types of digestion: mechanical digestion and chemical digestion. Mechanical digestion occurs when large chunks are turned into smaller chucks. Perhaps not surprisingly, this happens when you chew your food. Once you swallow the food, your stomach also does some of this work. Chemical digestion occurs when food is broken down into useful nutrients. This is a chemical process that begins as you start to chew your food. The saliva in your mouth starts this process. Once you swallow, the acid in your stomach further breaks down food. From the stomach, the foods moves into the small intestine. In the small intestines, another set of chemicals goes to work. Are you surprised? Your small intestine, and not your stomach, does most of the work!

Does the response "When large chunks of food are reduced to small chunks in the mouth" correctly answer the question "What is chemical digestion, and where does it occur?"?

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.

Before the mysterious disappearance of one of its passenger jets this month, Malaysia wasn't a country used to finding itself dominating headlines around the world. Some of its Southeast Asian neighbors, including Indonesia and the Philippines, have suffered devastating natural disasters in recent years and are all too familiar with the media frenzy that accompanies a major crisis. But Malaysia has largely managed to stay out of the international spotlight since its independence from British colonial rule more than half a century ago. "It is one of these countries, because of its geography, that doesn't have earthquakes," said Ernest Bower, senior adviser for Southeast Asia studies at the Center for Strategic and International Studies. "It doesn't have tsunamis. It hasn't been tested with a disaster like this." The disappearance of Malaysia Airlines Flight 370 has thrust the government into the dazzling glare of worldwide attention. And it hasn't emerged with very good grades. "I think on a stress test, they're failing," Bower told CNN's Jake Tapper, pointing to the government's coordination of different agencies and communication with other countries. China among critics Criticism and complaints have come from other countries involved in the search for the missing plane, including China and Vietnam, and from the relatives of passengers. Malaysian officials have created confusion by issuing contradictory statements on key aspects of the investigation. The majority of the people on board the plane were Chinese, and Beijing has increasingly voiced its displeasure with the search, especially after Malaysia announced over the weekend that evidence suggested the plane had been deliberately flown west into the Indian Ocean, away from its last confirmed location over the South China Sea. "The new information means the intensive search in the South China Sea for the whole past week was worthless and would never bear fruit," said a commentary published by China's state-run news agency Xinhua. "Even worse, the golden time for saving possible survivors, if any, was generously wasted."

Question: "According to the media, has the Malaysian government done well in responding to the disappearance of Flight 370?"

Little is known of the earliest Stone Age inhabitants of Europe's southwestern extremity. The ancient Greeks called them the Cynetes (or Cunetes). Whatever their origins, their culture evolved under the pressure and influence of foreign forces. Among the many invading armies that settled here and contributed to nascent Portuguese culture were Phoenicians, who settled in the area around 1,000 b.c., followed by the Celts, Iberians, Greeks, and Carthaginians. But it was the Romans, who arrived late in the third century b.c., who most greatly influenced all of Iberia. They built towns, industries, roads, and bridges, developed agriculture, and bequeathed the Latin language, of which Portuguese is a direct descendant. The Romans named the southwestern province of the peninsula Lusitania, oddly enough for one of the Celtiberian tribes they defeated, and by the third century a.d. had introduced Christianity. By the beginning of the fourth century the Algarve had a bishop in place, based in Faro. But Rome had already fallen into decay, and soon hordes of northern tribesmen took over the empire. The Algarve fell to the Visigoths in the mid-fifth century. Under Moorish Rule In a.d. 711, the Moors brought powerful armies from North Africa and launched a devastating attack on the Iberian peninsula, conquering much of what would become Spain and Portugal. They imposed Islam and left an indelible influence on the countryside and the population of the Algarve. The Moorish legacy can still be seen in the form of wells and waterwheels, squat white houses, the dark complexions of the people, and in the very name given the regiontaken from Al-Gharb, which means "country of the west" (when the Moors conquered the territory, it was the most westerly in the known world). The Moors governed their Iberian kingdoms from across the border in Seville, but the Algarve had its own regional capital and huge, invulnerable fortress. The capital was Chelb (or Xelb), and it was bigger and better defended than Lisbon. Today the town, known as Silves, is a provincial outpost whose only besiegers are busloads of tourists who climb the narrow streets up to the old Moorish ramparts.
