Final answer:
Gilberto Gil and Caetano Veloso were exiled from Brazil in 1969 due to political activism against the military dictatorship, as they were prominent figures in the Tropicalia movement challenging the political and social norms.
Step-by-step explanation:
Gilberto Gil and Caetano Veloso, two renowned Brazilian musicians, were exiled from Brazil in 1969 due to political activism. This period was marked by a military dictatorship in Brazil that suppressed any form of dissent or opposition, including those expressed through music and culture. As prominent figures in the Tropicalia movement, Gil and Veloso used their music to challenge social norms and the political status quo, which was seen as a threat by the authoritarian regime of the time. Their exile is an example of the dangers faced by intellectuals and artists who were deemed politically disruptive, much like the situation in Russia described earlier, where involvement in politics was a crime that led to exile.
