Nobody would have said 50 years ago that apartheid would have gone in 1990, or that the Berlin wall would have fallen at the turn of the '80s and '90s, or that polio could be eradicated, or perhaps 60 years ago, nobody would have said a man could gone to the Moon.
Nimeni nu ar fi zis acum 50 de ani ca apartheid-ul va disparea in 1990, ca zidul Berlinului va cadea la trecerea intre anii '80 si anii '90, sau ca poliomelita va fi eradicata, sau poate ca acum 60 de ani nimeni nu ar fi spus ca un om va ajunge pe Luna.
