I checked fivb site and finally it's clear who will be in pools in F6
Pool E: Host (Argentina), Pool B winner, Pool A runner-up
Pool F: Pool A winner, Pool C winner (Canada), Pool B runner-up
In pool A and B there are crucial matches this weekend so team in pool can change. Brazil it's almost certain in pool F, Italy in pool E and Russia in pool F. Germany can change this only by getting 6 points. Last place can be taken by Bulgaria/Poland/USA.
