QUES: The migrations and invasions of the 4th and 5th centuries disrupted trade networks around the Mediterranean. African goods stopped being imported into Europe, first disappearing from the interior and by the 7th century found only in a few cities such as Rome or Naples. By the end of the 7th century, under the impact of the Muslim conquests, African products were no longer found in Western Europe. The replacement of goods from long-range trade with local products was a trend throughout the old Roman lands that happened in the Early Middle Ages. This was especially marked in the lands that did not lie on the Mediterranean, such as northern Gaul or Britain. Non-local goods appearing in the archaeological record are usually luxury goods. In the northern parts of Europe, not only were the trade networks local, but the goods carried were simple, with little pottery or other complex products. Around the Mediterranean, pottery remained prevalent and appears to have been traded over medium-range networks, not just produced locally.
What non-local goods have archaeologists typically found in Britain of this era?

ANS: luxury goods

QUES: Iron is usually found as iron ore on Earth, except for one deposit of native iron in Greenland, which was used by the Inuit people. Native copper, however, was found worldwide, along with silver, gold and platinum, which were also used to make tools, jewelry, and other objects since Neolithic times. Copper was the hardest of these metals, and the most widely distributed. It became one of the most important metals to the ancients. Eventually, humans learned to smelt metals such as copper and tin from ore, and, around 2500 BC, began alloying the two metals to form bronze, which is much harder than its ingredients. Tin was rare, however, being found mostly in Great Britain. In the Middle East, people began alloying copper with zinc to form brass. Ancient civilizations took into account the mixture and the various properties it produced, such as hardness, toughness and melting point, under various conditions of temperature and work hardening, developing much of the information contained in modern alloy phase diagrams. Arrowheads from the Chinese Qin dynasty (around 200 BC) were often constructed with a hard bronze-head, but a softer bronze-tang, combining the alloys to prevent both dulling and breaking during use.
Around what time did bronze start being formed?

ANS: 2500 BC

QUES: The relational model also allowed the content of the database to evolve without constant rewriting of links and pointers. The relational part comes from entities referencing other entities in what is known as one-to-many relationship, like a traditional hierarchical model, and many-to-many relationship, like a navigational (network) model. Thus, a relational model can express both hierarchical and navigational models, as well as its native tabular model, allowing for pure or combined modeling in terms of these three models, as the application requires.
How was the relational model able to improve over time?

ANS: without constant rewriting of links and pointers

QUES: The most famous passage in Burke's Reflections was his description of the events of 5–6 October 1789 and the part of Marie-Antoinette in them. Burke's account differs little from modern historians who have used primary sources. His use of flowery language to describe it, however, provoked both praise and criticism. Philip Francis wrote to Burke saying that what he wrote of Marie-Antoinette was "pure foppery". Edward Gibbon, however, reacted differently: "I adore his chivalry". Burke was informed by an Englishman who had talked with the Duchesse de Biron, that when Marie-Antoinette was reading the passage, she burst into tears and took considerable time to finish reading it. Price had rejoiced that the French king had been "led in triumph" during the October Days, but to Burke this symbolised the opposing revolutionary sentiment of the Jacobins and the natural sentiments of those who shared his own view with horror—that the ungallant assault on Marie-Antoinette—was a cowardly attack on a defenceless woman.
Who thought the October Days were a cowardly attack on the Jacobins?
