Premise: Venezuelan President Hugo Chavez has said he is prepared to receive detainees held by the US military at the Guantanamo Bay camp in Cuba. US President Barack Obama has ordered the closure of the controversial camp, in which around 240 inmates are held, by next year. Mr Chavez made his offer at a summit of South American and Arab countries.  It is highly unlikely the Pentagon will take him up on it, however, given the poor state of US ties with Venezuela.
Hypothesis: Brazil was represented at this summit.
