[EX 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.

[EX Q]: Question: What modern day country did the Efe people populate? Passage:In modern times, the creation of relatively simple dome-like structures has been documented among various indigenous peoples around the world. The wigwam was made by Native Americans using arched branches or poles covered with grass or hides. The Efé people of central Africa construct similar structures, using leaves as shingles. Another example is the igloo, a shelter built from blocks of compact snow and used by the Inuit people, among others. The Himba people of Namibia construct "desert igloos" of wattle and daub for use as temporary shelters at seasonal cattle camps, and as permanent homes by the poor. Extraordinarily thin domes of sun-baked clay 20 feet in diameter, 30 feet high, and nearly parabolic in curve, are known from Cameroon.
