[Q]: Passage: Strategic Air Command was formed by the United States Air Force after World War II to provide an active defense against any surprise attack by the Soviet Union. Though it had been an ally against Germany and Japan during World War II, by 1948 the Soviet Union showed a propensity to instigate problems with Britain, France and the United States. In August 1949, the Soviet Union detonated its first nuclear weapon and by the early 1950s had detonated a hydrogen bomb. The war of words between the two superpowers escalated during 1950s and 1960s into a nuclear arms race. By 1970 the United States was using a "Triad Defense System" composed of nuclear submarines armed with nuclear missiles, land based intercontinental ballistic missiles with nuclear warheads and bombers capable of delivering hydrogen bombs on enemy targets. The Boeing B-52 Stratofortress bomber had been designed in the early 1950s by Boeing Aircraft Company to give the United States Air Force the capability of delivering nuclear weapons far inside the territory of Soviet Russia. The planes were to fly at high altitude with enough fuel to hit their target. In May 1960, the Soviet Union made known its capability to shoot such high altitude planes out of the sky by using a surface to air missile to strike CIA pilot Francis Gary Powers' U-2 spy plane over Russian territory. From that point on, the high-altitude B-52 had to be modified to conduct missions at low level, something it was not intended to be.

[Q]: Passage: In the eighth inning, Miguel Tejada singled, and with one out attempted to steal second base. Catcher Dioner Navarro made a poor throw to get Tejada, and the ball ended up in center field, allowing Tejada to advance to third base on the error. Tejada scored on a sacrifice fly by Adrian Gonzalez, and the NL retook the lead. In the bottom half of the inning, after Brian Wilson retired the first two batters, Billy Wagner gave up a single to Grady Sizemore. Sizemore proceeded to steal second base (one of a record six stolen bases by both sides), and pinch-hitter Evan Longoria hit a ground rule double to left field to tie the game once again. With Mariano Rivera in to pitch with one out in the ninth inning for the American League, Rivera struck out Ryan Ludwick and Navarro threw out Cristian Guzman as he attempted to steal second, thus ending the inning. Ryan Dempster struck out the side in the bottom of the ninth to force the game into extra innings.
