[Q]: Crew members ran for their lives when overhanging metalwork crashed onto a stage in a Toronto park Saturday afternoon, pinning and killing one man, authorities said. The collapse happened around 4 p.m., one hour before spectators were set to begin streaming in for a concert by the alternative rock group Radiohead. Several people were on the stage at the time, preparing for the show, when scaffolding-like material towering about 50 feet above collapsed. "Unfortunately, four people were hurt," Toronto police Constable Tony Vella said. "The remainder of the people, when they heard the stage coming (down), ran from the area." Firefighters arrived to find one man "trapped under the structure," said Toronto fire Platoon Chief Tony Bellavance. They helped to extricate the man, then moved away from what was then still considered an "unstable structure," Bellavance added. Paramedics, who happened to be at the scene in preparation for the concert, "immediately rendered aid," according to on-site Toronto Emergency Medical Services commander Peter Rotolo. The victim -- who has not been identified, amid efforts to contact his next of kin -- was pronounced dead at the scene. Police said he was in his 30s. Another man who suffered serious injuries due to the collapse was transported to Toronto's Sunnybrook Hospital, Ian McClelland of the city's EMS department said. The 45-year-old man suffered a head injury that isn't considered life-threatening, according to Toronto police. Two other men with minor injuries were assessed and released, McClelland said. Aerial footage afterward showed that some metal framing -- some of it covered in a blue material -- crumpled on the stage, which was in front of a large grassy area. Some of the scaffolding-like material remained standing, reaching about 50 feet in the sky. The stage was being set up especially for the Radiohead concert, Vella said. At the time it came down, the weather was good with no storm rolling through or significant winds, added fellow police Constable Harrison Ford. <sep>How old was the man who was dead at the scene?<sep>In his 30's
[A]: Yes

[Q]: You couldnt survive without your skin. It has many important functions. The main function of the skin is controlling what enters and leaves the body. It prevents the loss of too much water from the body. It also prevents bacteria and other microorganisms from entering the body. The skin helps maintain a constant body temperature. It keeps the body cool in two ways. Sweat from sweat glands in the skin evaporates to cool the body. Blood vessels in the skin dilate, or widen. This action increases blood flow to the body surface. This allows more heat to reach the surface. The heat is then able to radiate off the body. The opposite happens to retain body heat. Blood vessels in the skin constrict, or narrow. This decreases blood flow to the body surface. This reduces the amount of heat that reaches the surface. When this happens, less heat can be lost to the air. <sep>What happens when less heat reaches the surface of your skin?<sep>Cools the body
[A]: No

[Q]: Mary, Queen of Scots: The baby was Mary Stuart, who at the age of nine months was crowned Queen of Scots at the Chapel Royal, Stirling. When the news reached London, Henry VIII saw his chance to subdue Scotland again and negotiated a marriage between the infant Mary and his son Edward. The Scots refused, and Henry sent an army rampaging through Scotland on a campaign known as the "Rough Wooing. " The English king ordered his general to "burn Edinburgh town so there may remain forever a perpetual memory of the vengeance of God lightened upon the Scots. " But more was at stake than simply Scotland's independence: there was now a religious schism within Britain. In order to divorce Catherine of Aragon and marry Anne Boleyn, Henry VIII had broken with Rome and brought the English church under his own control. England was thus now a Protestant country, caught between Catholic France and the Scots with their new Catholic queen. The Scots themselves were divided, many embracing Protestantism in the spirit of the Reformation while others remained staunchly Catholic. However, fear of the rampaging English army led the Scots again to seek help from their old Ailies in France, and the young queen married the Dauphin Francois, son of the French king. Francois II became king of France in 1559 but died soon after. In 1561 the 18-year-old Mary returned to a Scotland in the grip of the Reformation, as Protestant leaders had taken control of the Scottish parliament and abolished the authority of the pope. Her Protestant cousin, Elizabeth Tudor, was on the English throne, but Elizabeththe "Virgin Queen"had no heir. Mary was next in line for the English crown, and Elizabeth was suspicious of her intentions. The six years of Mary's reign were turbulent ones. She clashed early on with Edinburgh's famous Protestant reformer, John Knox, who held sway in St. Giles but later adopted an uneasy policy of religious tolerance. In 1565 she married her young cousin Henry, Lord Darnley, much to the chagrin of Elizabeth (Darnley was a grandson of Margaret Tudor and thus also had a claim to the English throne). On 19 June 1566, in the royal apartments in Edinburgh Castle, Mary gave birth to a son, Prince James. Within a year, however, Darnley was murdered, and Mary immediately immersed herself in controversy by marrying the Earl of Bothwell, the chief suspect. <sep>How many times does Mary Stuart marry in this part of the story?<sep>Three times
