Problem: Since 1947, Canadian military units have participated in more than 200 operations worldwide, and completed 72 international operations. Canadian soldiers, sailors, and aviators came to be considered world-class professionals through conspicuous service during these conflicts and the country's integral participation in NATO during the Cold War, First Gulf War, Kosovo War, and in United Nations Peacekeeping operations, such as the Suez Crisis, Golan Heights, Cyprus, Croatia, Bosnia, Afghanistan, and Libya. Canada maintained an aircraft carrier from 1957 to 1970 during the Cold War, which never saw combat but participated in patrols during the Cuban Missile Crisis.
When did the Cold War take place?

Problem: In Mark, Jesus is crucified along with two rebels, and the day goes dark for three hours. Jesus calls out to God, then gives a shout and dies. The curtain of the Temple is torn in two. Matthew follows Mark, adding an earthquake and the resurrection of saints. Luke also follows Mark, though he describes the rebels as common criminals, one of whom defends Jesus, who in turn promises that he (Jesus) and the criminal will be together in paradise. Luke portrays Jesus as impassive in the face of his crucifixion. John includes several of the same elements as those found in Mark, though they are treated differently.
How did the criminals react to their own crucifixion?

Problem: New or "virgin" heavy/heavyweight (180220 g) vinyl is commonly used for modern audiophile vinyl releases in all genres. Many collectors prefer to have heavyweight vinyl albums, which have been reported to have better sound than normal vinyl because of their higher tolerance against deformation caused by normal play. 180 g vinyl is more expensive to produce only because it uses more vinyl. Manufacturing processes are identical regardless of weight. In fact, pressing lightweight records requires more care. An exception is the propensity of 200 g pressings to be slightly more prone to non-fill, when the vinyl biscuit does not sufficiently fill a deep groove during pressing (percussion or vocal amplitude changes are the usual locations of these artifacts). This flaw causes a grinding or scratching sound at the non-fill point.
Which pressing of vinyl require more attention to detail, lightweight or heavyweight?
