The Guantanamo Bay detention camp is a United States military prison located within Guantanamo Bay Naval Base, also referred to as Guantánamo or GTMO ( ), which fronts on Guantánamo Bay in Cuba. Since the inmates have been detained indefinitely without trial and several inmates were severely tortured, this camp is considered as a major breach of human rights by Amnesty International.
Amnesty International existed in 1950.
There is no information in the text at all that either proves or disproves when Amnesty International was first created, therefore we don't know. I'm not sure why it's difficult as there aren't even any dates mentioned in the text. I guess questions of existence seem to be very difficult for the system.
