Brazil: Rio de Janeiro begins one month countdown to Olympics

The mayor of Rio de Janeiro Eduardo Paes inaugurated the so-called 'Knowledge vault', an interactive space to detail the history of the Olympics Games, outside of Rio's Olympic Stadium, Tuesday.
Alongside Chairman of Rio 2016 Organising Committee Carlos Nuzman and Brazil's Sports Minister Leonardo Picciani, Paes opened the exhibition and took the chance to speak about the preparation progress.
According to Nuzman, Rio has undergone much development in the run-up to the game. He claimed, "The city of Rio de Janeiro experienced the greatest transformation in the history of the Olympic Games."
Tuesday marked the beginning of a 30-day countdown before the 2016 Olympic Games opening ceremony. Concerns have been raised, so close to the games, regarding unfinished facilities, construction problems, and planning issues.
