question:
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. <sep>Who settled in Iberia around 1000 B.C.? Name two armies.<sep>North African
answer:
No

question:
Energy is stored in chemical compounds. This energy is called chemical energy. Chemical energy is a form of potential energy. When bonds between atoms are broken, energy is released. The wood in fireplaces has chemical energy. The energy is released as heat and light when the wood burns. Most living things get their energy from food. When food molecules are broken down, the energy is released. It may then be used to do work, like playing ball or studying science. If you have ever heard, "Eat a good breakfast", thats why. You need energy to do things during the day. To do those things you need energy. You get your energy from the food you eat. That energy is stored in your body until you need it. How did you get to school today? If you walked, you used chemical energy from the food you ate. What if you rode the bus or were driven in a car? Where did that energy come from? <sep>In order for you to walk, what happens to bonds between atoms?<sep>They connect
answer:
No

question:
Maximilian's death came at a time when Durer was concerned he was losing "my sight and freedom of hand" (perhaps caused by arthritis) and increasingly affected by the writings of Martin Luther. In July 1520 Durer made his fourth and last major journey, to renew the Imperial pension Maximilian had given him and to secure the patronage of the new emperor, Charles V, who was to be crowned at Aachen. Durer journeyed with his wife and her maid via the Rhine to Cologne and then to Antwerp, where he was well received and produced numerous drawings in silverpoint, chalk and charcoal. In addition to going to the coronation, he made excursions to Cologne (where he admired the painting of Stefan Lochner), Nijmegen, 's-Hertogenbosch, Bruges (where he saw Michelangelo's Madonna of Bruges), Ghent (where he admired van Eyck's altarpiece), and Zeeland. Durer took a large stock of prints with him and wrote in his diary to whom he gave, exchanged or sold them, and for how much. This provides rare information of the monetary value placed on prints at this time. Unlike paintings, their sale was very rarely documented. While providing valuable documentary evidence, Durer's Netherlandish diary also reveals that the trip was not a profitable one. For example, Durer offered his last portrait of Maximilian to his daughter, Margaret of Austria, but eventually traded the picture for some white cloth after Margaret disliked the portrait and declined to accept it. During this trip he also met Bernard van Orley, Jan Provoost, Gerard Horenbout, Jean Mone, Joachim Patinir and Tommaso Vincidor, though he did not, it seems, meet Quentin Matsys. At the request of Christian II of Denmark, Durer went to Brussels to paint the King's portrait. There he saw "The things which have been sent to the king from the golden land"--the Aztec treasure that Hernan Cortes had sent home to Holy Roman Emperor Charles V following the fall of Mexico. Durer wrote that this treasure "was much more beautiful to me than miracles. These things are so precious that they have been valued at 100,000 florins". Durer also appears to have been collecting for his own cabinet of curiosities, and he sent back to Nuremberg various animal horns, a piece of coral, some large fish fins, and a wooden weapon from the East Indies. Having secured his pension, Durer finally returned home in July 1521, having caught an undetermined illness--perhaps malaria --which afflicted him for the rest of his life, and greatly reduced his rate of work. <sep>Why was it important that Durer wrote about the price of prints in his diary?<sep>Because this information was rarely documented
answer:
Yes
