question:
Question: In what year was CIA pilot Francis Gary Powers born? 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.

Question: Which opponent who beat Miskew's team in the first two Grand Slam of 2012-2013 season is the oldest? Passage:The 2012–13 curling season was Miskew's most successful to date on the World Curling Tour. In her first Grand Slam event of the season, the 2012 Curlers Corner Autumn Gold Curling Classic, her team lost to Sherry Middaugh in the final. In the second Grand Slam event of the season, the 2012 Manitoba Lotteries Women's Curling Classic, the Homan rink once again lost in the final, this time to Stefanie Lawton. The team lost in the semi-final of the third Slam, the 2012 Colonial Square Ladies Classic but followed it up with their first ever Grand Slam victory at the 2012 Masters of Curling where she beat Chelsea Carey in the final. Outside of the Grand Slams, Miskew and her team won the 2nd Royal LePage OVCA Women's Fall Classic. Later in the season, they qualified for her second Scotties Tournament of Hearts by going undefeated at the 2013 Ontario Scotties Tournament of Hearts. The Homan rink tore through the competition representing Ontario at the 2013 Scotties Tournament of Hearts in Kingston, Ontario. The team lost just one game, to Manitoba's Jennifer Jones. This gave the rink a 10–1 record, 2nd behind Manitoba who went undefeated. However in their first playoff game against Jones, the Homan rink made amends by defeating Jones 8–5. This put the Homan team in the final, where they faced Jones once again, and this time would beat them again, by a score of 9–6. With the win, the Homan rink becomes the first Ottawa-based team to win the Canadian women's curling championship. The win earned Miskew and her team the right to represent Canada at the 2013 World Women's Curling Championship in Riga, Latvia. At the World championships, the Homan rink led Canada to an 8–3 round robin finish, which put them in third place. In the playoffs, they beat the United States (skipped by Erika Brown) in the 3 vs. 4 game, but they then lost to Scotland (skipped by Eve Muirhead in the semi-final, after Homan missed her last shot of the game, jamming a double takeout. After the loss, Homan would go on to beat the Americans once again, this time in the bronze medal game. The Homan rink wrapped up the season by losing in the quarter final of the 2013 Players' Championship.
