[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: How old was the person elected in April 1999 when he was sworn in? Passage:Following the death of military dictator and de facto ruler of Nigeria, General Sani Abacha in 1998, his successor General Abdusalami Abubakar initiated the transition which heralded Nigeria's return to democratic rule in 1999. The ban on political activities was lifted, and political prisoners were released from detention facilities. The constitution was styled after the ill-fated Second Republic — which saw the Westminster system of government jettisoned for an American Presidential system. Political parties were formed (People's Democratic Party (PDP), All Nigeria Peoples Party (ANPP), and Alliance for Democracy (AD)), and elections were set for April 1999. In the widely monitored 1999 election, former military ruler Olusegun Obasanjo was elected on the PDP platform. On 29 May 1999, Obasanjo was sworn in as President and Commander-in-Chief of the Federal Republic of Nigeria.
