Before the Great Depression, Argentina was making lots of money from meat production. But when the Depression hit, the people turned to authoritarian leadership. The military general Juan Perón took power after World War II. His wife Eva Perón was quite popular, and while she was alive, Perón enjoyed much support. She was especially popular with poor workers known as the descamisados, or "shirtless ones." But a popular leader with a pretty face can distract from the abuses behind the scenes. During Perón's dictatorship, which lasted until his death, he supported the "Dirty War," in which the government sponsored the killing of up to 30,000 people who opposed government views. The people who were killed were known as the "disappeared," since they were taken out of their homes or off the street by secret police and never heard from again. It is assumed that the government killed them. Finally, in 1983 a civilian government was reinstated. Who were the “disappeared”?

A. poor workers who loved Eva Perón
B. secret police in Argentina
C. 30,000 people who were killed in Argentina
D. the civilian government that was reinstated in 1983
