[EX Q]: Question: How long had the Atlanta Braves been a team when the Mets swept them in a National League Championship Series? Passage:The Mets went on to sweep the Atlanta Braves in the 1969 National League Championship Series, but were heavy underdogs heading into the 1969 World Series against the Baltimore Orioles. Following a 4-1 loss in the series opener with Cy Young award winner Seaver on the mound, it seemed as if the Mets had little chance against the Orioles. However, the Mets bounced back, winning the next four games to capture their first world championship. Besides catching every inning in the post-season, Grote contributed offensively with a single in Game Two to keep a ninth inning rally alive and Al Weis followed with the game-winning hit. With Game Four tied, Grote doubled to start the tenth inning, then pinch runner Rod Gaspar scored the winning run when an errant throw hit J.C. Martin on the wrist. With Grote calling the pitches, the Mets pitching staff held the Orioles hitters to a .146 batting average during the series.

[EX 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.

[EX Q]: Question: How long had Sydney been established the year that Bob Heffron moved there to become the secretary of the New South Wales branch of the Federated Marine Stewards' and Pantrymen's Association of Australasia? Passage:In 1921, the Heffrons moved to Melbourne, Victoria. That same year in Victoria, Heffron was appointed an organiser for the Federated Clothing Trades of the Commonwealth of Australia and also joined the leftist Victorian Socialist Party. Later in 1921 he moved to Sydney, becoming the secretary of the New South Wales branch of the Federated Marine Stewards' and Pantrymen's Association of Australasia. As the union's state secretary, a role he would hold for ten years, he took a prominent role in maritime trade unionism in Sydney. In February 1924, when the Commonwealth and Dominion Line steamer Port Lyttelton was declared 'Black' by the Labor Council of New South Wales owing to various worker's disputes and the ship having been declared unseaworthy, Heffron and six other union representatives acted to advise members of the Seamen's Union to refuse to work on the Port Lyttelton. For this, in April the government of Sir George Fuller had Heffron and the six other unionists arrested on the charge of conspiracy to strike action. Although controversially refused bail by the trial judge, Heffron and his fellow defendants, represented by Richard Windeyer KC and H. V. Evatt, were found not guilty and released in July 1924 by the court, a verdict that had been returned by the direction of the judge. Later joining the Labor Party, at the time he showed himself to be a supporter of party leader Jack Lang, supporting Lang's successful motion at the 1923 state conference to readmit James Dooley to the party.
