Britain's first use of brass occurred around the 3rd–2nd century BC. In North America, copper mining began with marginal workings by Native Americans. Native copper is known to have been extracted from sites on Isle Royale with primitive stone tools between 800 and 1600. Copper metallurgy was flourishing in South America, particularly in Peru around 1000 AD; it proceeded at a much slower rate on other continents. Copper burial ornamentals from the 15th century have been uncovered, but the metal's commercial production did not start until the early 20th century.

Charles "Wag" Bennett, one of the judges at the 1966 competition, was impressed with Schwarzenegger and he offered to coach him. As Schwarzenegger had little money, Bennett invited him to stay in his crowded family home above one of his two gyms in Forest Gate, London, England. Yorton's leg definition had been judged superior, and Schwarzenegger, under a training program devised by Bennett, concentrated on improving the muscle definition and power in his legs. Staying in the East End of London helped Schwarzenegger improve his rudimentary grasp of the English language. Also in 1966, Schwarzenegger had the opportunity to meet childhood idol Reg Park, who became his friend and mentor. The training paid off and, in 1967, Schwarzenegger won the title for the first time, becoming the youngest ever Mr. Universe at the age of 20. He would go on to win the title a further three times. Schwarzenegger then flew back to Munich, training for four to six hours daily, attending business school and working in a health club (Rolf Putziger's gym where he worked and trained from 1966–1968), returning in 1968 to London to win his next Mr. Universe title. He frequently told Roger C. Field, his English coach and friend in Munich at that time, "I'm going to become the greatest actor!"
Which of the bodybuilders Schwarzenegger idolized as a kid did he meet in 1966?
A: Reg Park

The predominant school of thought in the 13th century was the Thomistic reconciliation of the teachings of Aristotle with Christian theology. The Condemnation of 1277, enacted at the University of Paris, placed restrictions on ideas that could be interpreted as heretical; restrictions that had implication for Aristotelian thought. An alternative was presented by William of Ockham, who insisted that the world of reason and the world of faith had to be kept apart. Ockham introduced the principle of parsimony – or Occam's razor – whereby a simple theory is preferred to a more complex one, and speculation on unobservable phenomena is avoided.
Which philosophy attempted to reconcile Aristotelian teachings and Christian theology in the 12th century?

On the field at the beginning of a play are two teams of 12 (unlike 11 in American football). The team in possession of the ball is the offence and the team defending is referred to as the defence. Play begins with a backwards pass through the legs (the snap) by a member of the offensive team, to another member of the offensive team. This is usually the quarterback or punter, but a "direct snap" to a running back is also not uncommon. If the quarterback or punter receives the ball, he may then do any of the following:
How many possessions does each team have in an American game?
