We've eventually sorted out our test group into three demographics, now it's up to the board to pick which group gets put in the thing.
[X] Military: Made up of soldiers, veterans and their families, this test group would have reacted best overall. Predictions indicate the constant threat and lack of weapons will have forced them to adapt. Society is strict and regimented. Food is rationed; there is little room for thought outside of battle. Even so, they have turned themselves into excellent soldiers.
{X] Scientists: Thinkers, learners and dreamers, this test group would have reacted worst initially being unused to combat. Still after the initial shock and loss of population it is predicted that depending on the surviving scientists they will pool their knowledge and create a counter to the creatures. It could be advanced robots, laser weapons or something else.
[X] Artists: Another name for these people would be hippies, but lets be fair. When placed in the vault it is anticipated that they will try to live as normally as possible, but when the moles come they may attempt to control them. How we're not sure, maybe tributes of food or soothing music, but our best predictions are that they will control them. It satisfies the terms of the experiment, they will eliminate the threat I suppose.
We are ready to begin the process immediately, just waiting for the word.
