You are the leader in a group of 9 scouts.
There are rumors of an incoming enemy army and your unit was sent to investigate where they are coming from.
You are aware that there are only 4 paths to your base.
You must divide your members into groups to investigate which one it will be.
Two members of your unit(excluding you) are unpredictable jokers who cannot be trusted.
You don't have much time left so you must send everyone(including you) immediately.
Everyone must report back and then you must be able to tell for sure where the enemy will come from.
How will you proceed?
