Task: Question Generation
Input (English): In 1978, Josep Lluís Núñez became the first elected president of FC Barcelona, and, since then, the members of Barcelona have elected the club president. The process of electing a president of FC Barcelona was closely tied to Spain's transition to democracy in 1974 and the end of Franco's dictatorship. The new president's main objective was to develop Barcelona into a world-class club by giving it stability both on and off the pitch. His presidency was to last for 22 years, and it deeply affected the image of Barcelona, as Núñez held to a strict policy regarding wages and discipline, letting go of such players as Maradona, Romário and Ronaldo rather than meeting their demands.
Output (English): How long was Nunez president of Barcelona?
