[EX Q]: Question: What institution did Fukuyama work for the year START II was signed? Passage:In August 1991, hard-line Communists launched a coup against Gorbachev; while the coup quickly fell apart, it broke the remaining power of Gorbachev and the central Soviet government. Later that month, Gorbachev resigned as general secretary of the Communist party, and Russian president Boris Yeltsin ordered the seizure of Soviet property. Gorbachev clung to power as the President of the Soviet Union until December 1991, when the Soviet Union dissolved. Fifteen states emerged from the Soviet Union, and of those states, Russia was the largest and most populous. Bush and Yeltsin met in February 1992, declaring a new era of "friendship and partnership". In January 1993, Bush and Yeltsin agreed to START II, which provided for further nuclear arms reductions on top of the original START treaty. The collapse of the Soviet Union prompted reflections on the future of the world following the end of the Cold War; one political scientist, Francis Fukuyama, speculated that humanity had reached the "end of history" in that liberal, capitalist democracy had permanently triumphed over Communism and fascism. Meanwhile, the collapse of the Soviet Union and other Communist governments led to post-Soviet conflicts in Central Europe, Eastern Europe, Central Asia, and Africa that would continue long after Bush left office.

[EX Q]: Question: Where did the Philadelphia Eagles play their home games when Ronnie Brown played for the team? Passage:Brown was drafted second overall by the Miami Dolphins in the 2005 NFL Draft. Brown started at running back for the Dolphins for the first four weeks of the season while Ricky Williams served a suspension, and shared carries with him when he returned in week five. Brown became the feature back in 2006 due to Williams' full year suspension. Brown sat out three games due to a broken hand suffered on Thanksgiving Day in a game against the Detroit Lions, returning in week 16. He played in the first seven games of the 2007 season before suffering a knee injury which knocked him out for the remainder of the season. Williams started over Brown in the first two games of the 2008 season, but shared carries with him after week two. Brown had 916 yards and ten touchdowns in 2008, which led to his first Pro Bowl selection following the season. He was placed on injured reserve for the second straight season after suffering a foot injury in week nine of the 2009 season. Brown rushed for 734 yards and five touchdowns in 2010, as he started in all 16 games. He played for the Philadelphia Eagles in 2011 following a six-year career with the Dolphins.
