Q: Question: Who was the leader of Solidarity in 1991? Passage:The 1991 Polish parliamentary election was held on 27 October 1991 to elect deputies to both houses of the National Assembly. The 1991 election was notable on several counts. It was the first parliamentary election to be held since the formation of the Third Republic, the first entirely free and competitive legislative election since the fall of communism, the first completely free legislative election of any sort since 1928, and only the fifth completely free election in all of Polish history. Due to the collapse of the Solidarity movement's political wing, the 1991 election saw deep political fragmentation, with a multitude of new parties and alliances emerging in its wake. Low voting thresholds within individual constituencies, along with a five percent national threshold allocated to a small portion of the Sejm, additionally contributed to party fragmentation. As a result, 29 political parties gained entry into the Sejm and 22 in the Senate, with no party holding a decisive majority. Two months of intense coalition negotiations followed, with Jan Olszewski of the Centre Agreement forming a minority government along with the Christian National Union, remnants of the broader Center Civic Alliance, and the Peasants' Agreement, with conditional support from Polish People's Party, Solidarity and other minor parties.

Q: Question: What does it mean to have a perfect game in baseball? Passage:On May 26, 1959, in the 13th inning of a game against the Pittsburgh Pirates at Milwaukee County Stadium, Mantilla ruined Harvey Haddix's bid for a perfect game. Leading off the inning, he hit a ground ball to third baseman Don Hoak, whose throw to first pulled Rocky Nelson off the bag for an error. (Mantilla had not even been in the starting lineup; he entered the game in the 11th after Del Rice had pinch-hit for Johnny O'Brien.) Mantilla was sacrificed to second by Eddie Mathews, followed by an intentional walk to Hank Aaron. The following batter, Joe Adcock, hit one over the right-center field wall, just beyond the reach of right fielder Joe Christopher (who was making his Major League debut), for an apparent 3–0 victory. Mantilla scored the winning run, but Aaron, thinking the ball was still in play and that the game ended when Mantilla scored the winning run, rounded second and then headed for the dugout. Adcock, running out his home run, passed Aaron on the bases; as a result, the ruling from National League president Warren Giles was that Adcock's hit was a double (not a home run), only Mantilla's run counted and the final score was 1–0.
