Task: Question Generation
Input (English): Passage: The history of Solidarity (Polish: Solidarność, pronounced [sɔliˈdarnɔɕt͡ɕ] (listen)), a Polish non-governmental trade union, began on August 14, 1980, at the Lenin Shipyards (now Gdańsk Shipyards) at its founding by Lech Wałęsa and others. In the early 1980s, it became the first independent labor union in a Soviet-bloc country. Solidarity gave rise to a broad, non-violent, anti-communist social movement that, at its height, claimed some 9.4 million members. It is considered to have contributed greatly to the fall of communism.
Poland's communist government attempted to destroy the union by instituting martial law in 1981, followed by several years of political repression, but in the end was forced into negotiation. The Roundtable Talks between the government and the Solidarity-led opposition resulted in semi-free elections in 1989. By the end of August 1989, a Solidarity-led coalition government had been formed, and, in December 1990, Wałęsa was elected president. This was soon followed by the dismantling of the communist governmental system and by Poland's transformation into a modern democratic state. Solidarity's early survival represented a break in the hard-line stance of the communist Polish United Workers' Party (PZPR), and was an unprecedented event; not only for the People's Republic of Poland—a satellite of the USSR ruled by a one-party communist regime—but for the whole of the Eastern bloc. Solidarity's example led to the spread of anti-communist ideas and movements throughout the Eastern Bloc, weakening communist governments. This process later culminated in the Revolutions of 1989.
In the 1990s, Solidarity's influence on Poland's political scene waned. A political arm of the "Solidarity" movement, Solidarity Electoral Action (AWS), was founded in 1996 and would win the Polish parliamentary elections in 1997, only to lose the subsequent 2001 elections. Thereafter, Solidarity had little influence as a political party, though it did become the largest trade union in Poland.
Output (English): What was the name of the largest trade union in Poland?
