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.

Question: Were the two anarchists that Oerter met in New York born outside of United States? Passage:By the early 1890s he had moved away from Bavaria and, with his brother, was working in Duisburg. Together the brothers smuggled subversive anarchist literature into Germany from the Netherlands. Coming under increasing police pressure, and taking his queue from a number of other anarchist comrades in a similar predicament, early in 1892 he fled to the United States of America. On his arrival at New York he met up with the circle around Emma Goldman, Alexander Berkman, and politically like-minded comrades from Germany. Sepp Orter discovered in himself a talent for activism, turning out to have a flair for public speaking. During 1892 he was also the editor of the New York version of , published by the "Radical Workers' Association" ("Radikaler Arbeiter Bund") and the "Autonomy" group which also numbered among its members Josef Peukert. The stay in America was cut short, however. The authorities suspected that Oerter had somehow been involved in Alexander Berkman's attempt to assassinate a wealthy businessman called Henry Clay Frick. Those suspicions appear not to have been entirely unfounded. With financial assistance from Emma Goldman, Sepp Oerter returned to Germany. He travelled via London where he arrived in October, and where the editorial group publishing "Autonomy" gave him a mission to take printed material across Belgium to the German frontier in order to effect a clandestine introduction of the anarchist propaganda to Germany. Sepp Oerter was able to complete his mission with the help of his brother Fritz who had stayed behind when Sepp had escaped to America.

Question: How many times was he successively a member of the Labor Party? Passage:Billy Hughes was a former prime minister who had been successively a member of the Labor Party, the National Labor Party, and the Nationalist Party. By 1928, he was the de facto leader of a group of backbenchers hostile to the government of Stanley Bruce (who had replaced him as Nationalist leader in 1923). He and his supporters began to frequently cross the floor and vote against the government, particularly on the controversial subject of industrial relations. On 22 August 1929, Hughes and Edward Mann were expelled from the Nationalist Party for voting in favour of an unsuccessful censure motion against the government. Tensions finally came to a head on 10 September, when Hughes successfully moved an amendment to the government's flagship Maritime Industries Bill. Bruce took this to be a vote of no confidence, and called an election for 12 October. Labor under James Scullin won a landslide victory, while Hughes and two other ex-Nationalists were re-elected as independents.
