I would take 3 of the fetile women, and the farmer and medical student. And the police officer. 3 women and 3 men gives you a total of 9 different pairings, and 9 different offspring. 4 women and two men would only give you 8 different offspring. I picked the men and women solely on their breeding ability and skills. The police officer was the final male, and was a good choice. Most policemen at that age are in decent physical condition. he is skilled in firearms which would be a plus if we were forced too hunt.



Also if doesnt say if the event would destroy everything non-living. like buildings and cities and such. That might figure a bit differently.
