Question: Copper occurs naturally as native copper and was known to some of the oldest civilizations on record. It has a history of use that is at least 10,000 years old, and estimates of its discovery place it at 9000 BC in the Middle East; a copper pendant was found in northern Iraq that dates to 8700 BC. There is evidence that gold and meteoric iron (but not iron smelting) were the only metals used by humans before copper. The history of copper metallurgy is thought to have followed the following sequence: 1) cold working of native copper, 2) annealing, 3) smelting, and 4) the lost wax method. In southeastern Anatolia, all four of these metallurgical techniques appears more or less simultaneously at the beginning of the Neolithic c. 7500 BC. However, just as agriculture was independently invented in several parts of the world, copper smelting was invented locally in several different places. It was probably discovered independently in China before 2800 BC, in Central America perhaps around 600 AD, and in West Africa about the 9th or 10th century AD. Investment casting was invented in 45004000 BC in Southeast Asia and carbon dating has established mining at Alderley Edge in Cheshire, UK at 2280 to 1890 BC. Otzi the Iceman, a male dated from 33003200 BC, was found with an axe with a copper head 99.7% pure; high levels of arsenic in his hair suggest his involvement in copper smelting. Experience with copper has assisted the development of other metals; in particular, copper smelting led to the discovery of iron smelting. Production in the Old Copper Complex in Michigan and Wisconsin is dated between 6000 and 3000 BC. Natural bronze, a type of copper made from ores rich in silicon, arsenic, and (rarely) tin, came into general use in the Balkans around 5500 BC.[citation needed]

Answer: 2800 BC
Question: The Greek national basketball team has a decades-long tradition of excellence in the sport, being considered among the world's top basketball powers. As of 2012, it ranked 4th in the world and 2nd in Europe. They have won the European Championship twice in 1987 and 2005, and have reached the final four in two of the last four FIBA World Championships, taking the second place in the world in 2006 FIBA World Championship, after a spectacular 10195 win against Team USA in the tournament's semifinal. The domestic top basketball league, A1 Ethniki, is composed of fourteen teams. The most successful Greek teams are Olympiacos, Panathinaikos, Aris Thessaloniki, AEK Athens and P.A.O.K. Greek basketball teams are the most successful in European basketball the last 25 years, having won as many as 9 Euroleagues since the establishment of the modern era Euroleague Final Four format in 1988, while no other nation has won more than 4 Euroleague championships in this period. Besides the 9 Euroleagues, Greek basketball teams (Panathinaikos, Olympiacos, Aris Thessaloniki, AEK Athens, P.A.O.K, Maroussi) have won 3 Triple Crowns, 5 Saporta Cups, 2 Korac Cups and 1 FIBA Europe Champions Cup. After the 2005 European Championship triumph of the Greek national basketball team, Greece became the reigning European Champion in both football and basketball.

Answer: Team USA
Question: The Arabic term ijazat al-tadris was awarded to Islamic scholars who were qualified to teach. According to Makdisi, the Latin title licentia docendi 'licence to teach' in the European university may have been a translation of the Arabic, but the underlying concept was very different. A significant difference between the ijazat al-tadris and the licentia docendi was that the former was awarded by the individual scholar-teacher, while the latter was awarded by the chief official of the university, who represented the collective faculty, rather than the individual scholar-teacher.

Answer: unanswerable
Question: The goalkeepers are the only players allowed to touch the ball with their hands or arms while it is in play and only in their penalty area. Outfield players mostly use their feet to strike or pass the ball, but may also use their head or torso to do so instead. The team that scores the most goals by the end of the match wins. If the score is level at the end of the game, either a draw is declared or the game goes into extra time and/or a penalty shootout depending on the format of the competition. The Laws of the Game were originally codified in England by The Football Association in 1863. Association football is governed internationally by the International Federation of Association Football (FIFA; French: Federation Internationale de Football Association), which organises World Cups for both men and women every four years.
