In The Purmamarca Educational Reserve there is one item in Gold where you have to fulfill guests hunger needs to 70%. In the scenario. The wording in the actual list says "Increase guest average hunger to 70%" this is ambiguous and confusing to some people. It can be interpreted as needing to make your guests hungrier until they reach and average of 70%. I, and a several other players, were stuck in this scenario for a long time for this reason. If this read something like "Satisfy guest average hunger to 70%" this would be much clearer.
