Task: Question Understanding
Input (English): Passage: After successive defeats suffered in the revolutions of 1890 and 1893, and not having achieved free and fair elections, the Radical Civic Union entered a serious crisis, which deepened after 1896 with the suicide of Leandro N. Alem and the death of Aristóbulo del Valle. In 1897, Hipólito Yrigoyen, profoundly disagreeing with the direction of agreements imposed by Bernardo de Irigoyen, dissolved the Committee of the RCU in the province of Buenos Aires, due to which the radical party practically ceased to exist. The dissolution of the Radical Civic Union resulted in the formation of a core of radical elements that recognized as their leader Hipólito Yrigoyen. Onto this core - composed of young men, recruited from the middle class, professionals, businessmen, employees, ranchers of the old federal tradition, settlers and laborers from the countryside - was Yrigoyen able to impose discipline and enthusiasm. In this context, in 1903 Hipólito Yrigoyen began his revival and reorganization. On February 29 of 1904, after 7 years of inactivity, the National Committee of the Radical Civic Union said the electoral abstention of all the radicals of the Republic in the elections of representatives from the nation, senators from the capital, electors for president and vice president of the nation, and announced an armed resistance.
Question: Before 1904, when was the last time National Committee of the Radical Civic Union was active?
