Article: The most widely used symbol is the flag of Greece, which features nine equal horizontal stripes of blue alternating with white representing the nine syllables of the Greek national motto Eleftheria i thanatos (freedom or death), which was the motto of the Greek War of Independence. The blue square in the upper hoist-side corner bears a white cross, which represents Greek Orthodoxy. The Greek flag is widely used by the Greek Cypriots, although Cyprus has officially adopted a neutral flag to ease ethnic tensions with the Turkish Cypriot minority see flag of Cyprus).

Question: What are the representations of the Greek reference freedom or death that are held on a cloth symbol of the nation ?
Ans: flag of Greece, which features nine equal horizontal stripes of blue alternating with white

Article: Technology magazine T3 gave the Super Slim model a positive review, stating the console is almost "nostalgic" in the design similarities to the original "fat" model, "While we don't know whether it will play PS3 games or Blu-ray discs any differently yet, the look and feel of the new PS3 Slim is an obvious homage to the original PS3, minus the considerable excess weight. Immediately we would be concerned about the durability of the top loading tray that feels like it could be yanked straight out off the console, but ultimately it all feels like Sony's nostalgic way of signing off the current generation console in anticipation for the PS4."

Question: What PlayStation 3 model did T3 feel the Super Slim's design was paying homage to?
Ans: the original PS3

Article: The concentration of copper in ores averages only 0.6%, and most commercial ores are sulfides, especially chalcopyrite (CuFeS2) and to a lesser extent chalcocite (Cu2S). These minerals are concentrated from crushed ores to the level of 1015% copper by froth flotation or bioleaching. Heating this material with silica in flash smelting removes much of the iron as slag. The process exploits the greater ease of converting iron sulfides into its oxides, which in turn react with the silica to form the silicate slag, which floats on top of the heated mass. The resulting copper matte consisting of Cu2S is then roasted to convert all sulfides into oxides:

Question: What does heating copper ore materials with silica remove?
Ans: iron

Article: Thermally, a temperate glacier is at melting point throughout the year, from its surface to its base. The ice of a polar glacier is always below freezing point from the surface to its base, although the surface snowpack may experience seasonal melting. A sub-polar glacier includes both temperate and polar ice, depending on depth beneath the surface and position along the length of the glacier. In a similar way, the thermal regime of a glacier is often described by the temperature at its base alone. A cold-based glacier is below freezing at the ice-ground interface, and is thus frozen to the underlying substrate. A warm-based glacier is above or at freezing at the interface, and is able to slide at this contact. This contrast is thought to a large extent to govern the ability of a glacier to effectively erode its bed, as sliding ice promotes plucking at rock from the surface below. Glaciers which are partly cold-based and partly warm-based are known as polythermal.

Question: From where is the temperature of a glacier measured?
Ans:
base alone
