Question: Do dragons appear in Greek Mythology outside of the chimera? Passage:The chimera of Greek mythology appeared in Marvel Comics. It is depicted as a fire-breathing monster with the heads of a lion and a goat next to each other, the front legs of a lion, the wings of a dragon, the hindquarters of a goat, and a snake-headed tail, while also possessing the power of speech. Its history of being the offspring of Echidna and being slain by Bellerophon is still mentioned. At some point, the Chimera was restored to life by Hera to guard the caverns underneath New Olympus. It was accompanied in this job by a Cyclops and some Skeleton Warriors. The Chimera encountered the Agents of Atlas. When it didn't see that they were Olympians, Chimera breathed fire at them, sparking a fight between the heroes and the minions of Hera. Gorilla-Man forced the chimera to set its second head ablaze, causing it to flail around until it was knocked unconscious.

Question: Which team won more games the year Cowan started with the Rams, the Vikings or the Cowboys? Passage:Charles Edward Cowan (June 19, 1938 in Braeholm, West Virginia April 29, 1998 in Los Angeles, California) was an American football offensive tackle who played fifteen seasons in the National Football League with the Los Angeles Rams from 1961 to 1975. Cowan was a huge intimidating presence on the left of Tom Mack, a member of the Pro Football Hall of Fame, from 1966 to 1975, forming a potent left side of the offensive line, with help from Ken Iman at center from 1965 to 1975. In that 1961 to 1975 span, the Rams made the playoffs 5 times (1967,1969,1973,1974,1975), reaching the NFC championship game of the 1974-75 NFL playoffs and the 1975-76 NFL playoffs, but losing to the Minnesota Vikings and to the Dallas Cowboys, respectively. In the 1974 divisional round, the Rams defeated the Washington Redskins, as Cowan was successful against the opposing the right defensive end Verlon Biggs. In the 1975 divisional round, Doug France started in his place as the Rams defeated the St. Louis Cardinals. Cowan came back to play against the Cowboys, his final game, as the Rams could not get past them. Cowan was replaced by Doug France in 1976.

Question: How many years were there between the end of the British Burma Campaign and the start of the Battle of Na San? Passage:The First Indochina War had raged, as guerrilla warfare, since 19 December 1946. From 1949, it evolved into conventional warfare, due largely to aid from the communists of the People's Republic of China ("PRC") to the north. Subsequently, the French strategy of occupying small, poorly defended outposts throughout Indochina, particularly along the Vietnamese-Chinese border, started failing. Thanks to the terrain, popular support for August Revolution and support for decolonization from bordering China and the U.S.S.R., the Viet Minh had succeeded in turning a "clandestine guerrilla movement into a powerful conventional army", following asymmetric warfare theory laid by Mao Tse Tung, something which previously had never been encountered by the western colonial powers. In October 1952, fighting around the Red River Delta spread into the Thai Highlands, resulting in the Battle of Na San, at which the Viet Minh were defeated. The French used the lessons learned at Na San strong ground bases, versatile air support, and a model based on the British Burma Campaign as the basis for their new strategy. The Viet Minh, however, remained unbeatable in the highland regions of Vietnam, and the French "could not offset the fundamental disadvantages of a roadbound army facing a hill and forest army in a country which had few roads but a great many hills and forests".
