[Q]: Question: Did Sparta exist beyond 371? Passage:The scale and scope of warfare in Ancient Greece changed dramatically as a result of the Greco-Persian Wars, which marked the beginning of Classical Greece (480-323 BC). To fight the enormous armies of the Achaemenid Empire was effectively beyond the capabilities of a single city-state. The eventual triumph of the Greeks was achieved by alliances of many city-states, on a scale never seen before. The rise of Athens and Sparta during this conflict led directly to the Peloponnesian War, which saw diversification of warfare. Emphasis shifted to naval battles and strategies of attrition such as blockades and sieges. Following the defeat of the Athenians in 404 BC, and the disbandment of the Athenian-dominated Delian League, Ancient Greece fell under the Spartan hegemony. But this was unstable, and the Persian Empire sponsored a rebellion by the combined powers of Athens, Thebes, Corinth and Argos, resulting in the Corinthian War (395-387 BC). Persia switched sides, which ended the war, in return for the cities of Ionia and Spartan non-interference in Asia Minor. The Spartan hegemony would last another 16 years, until, at the Battle of Leuctra (371) the Spartans were decisively defeated by the Theban general Epaminondas.

[Q]: 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.
