This.
At this point, regardless of what happens, it's pretty much a 50/50 chance. The question is whether we want ONE person (inspira) to make all the choices (i.e., not a good idea if he is The Mole). Or do we want three separate people (meaning if one IS the Mole, they can sabotage, but they can only sabotage three boxes, vs. the 2 good ones like the mole can).
Pretty much, Inspira was correct previously. The only real factor now is who is the mole if they can open boxes and how many.
Scenario 1: Inspira has to choose one of 4 boxes. This is the same as Inspira eliminating Box 1, Box 2, and Box 4.
Scenario 2: We choose a box for Inspira. Person A eliminates Box 1, Person B eliminates Box 3, Person C eliminates Box 4.
Either way it's 50/50 at this point. The only difference is whether we let ONE person make all the decisions, or we let 3 separate people make all the choices. Also, I was incorrect in stating that "if there is only one money box left, we should stop opening boxes". It's actually doesn't matter (unless of course The Mole who has info opens the money box, at which point he exposes himself, but bottom line being it doesn't matter if we keep opening boxes).
