Answer:
The event that enabled the formation of a democratic government in Argentina in 1983 was the defeat in the Falklands War, which weakened the military regime.
Explanation:
The military regime began in Argentina in 1976, with the coup led by Videla, Massera and Agosti. There began the forced disappearances of people and the clandestine detention centers, but these were not the cause of the return of democracy, since the majority of the people were not aware of the situation.
What generated the return of democracy in Argentina was the loss of support for the regime by the people, caused after the defeat in the Falklands War against the United Kingdom in 1982. This event showed the people that the military regime was leading actions that did not benefit the people or the country itself, in addition to demonstrating that the military could be effectively defeated. In this way, the military President of that time, Galtieri, resigned his position. He was replaced by Bignone, who led the transition to a new democratic regime through elections in 1983, in which Alfonsin was elected.
