Task: Question Generation
Input (English): The elections of 2010 resulted in a victory for the military-backed Union Solidarity and Development Party. Various foreign observers questioned the fairness of the elections. One criticism of the election was that only government sanctioned political parties were allowed to contest in it and the popular National League for Democracy was declared illegal. However, immediately following the elections, the government ended the house arrest of the democracy advocate and leader of the National League for Democracy, Aung San Suu Kyi, and her ability to move freely around the country is considered an important test of the military's movement toward more openness. After unexpected reforms in 2011, NLD senior leaders have decided to register as a political party and to field candidates in future by-elections.
Output (English): What was the Burmese official decision concerning the legitimacy of National League for Democracy in 2010 ?
