As promised, one hypothetical dilemma

The Situation:

Three days ago, nuclear war broke out around the world with massive attacks in all heavily populated areas. For the first 24 hours, radio broadcasts reported tremendous damage and loss of life in all areas, including the near-total annihilation of most of the earth's population.

For the past 48 hours there have been no broadcasts. Fortunately, the people listed below were able to reach a fallout shelter in time to take cover and survived the initial devastation. They have a radio transmitter/receiver, through which they were able to make contact with you,  a scientist working alone at an isolated government monitoring facility that is still intact.  Having heard nothing to the contrary, you can only assume that those in the shelter are the only other survivors left on Earth.

The dilemma: there are currently 12 people in the fallout shelter, but there is not enough food, water, and other supplies to keep them all alive until the contamination in the atmosphere has dropped to safe levels. To survive, the people must stay inside the fallout shelter for at least three months. The problem is that if all of them stay in the shelter, all of them will starve to death or die of dehydration. There are enough supplies to allow 7 of the 12 people to survive.

Your task is to decide, based only on the information given, which people will be allowed to remain, and which people will be required to leave. They have all agreed to abide by your decision without question or debate, and will leave peacefully if they are ordered to do so.  

At stake is the survival of humanity. If human beings are to repopulate the Earth, such re-population will begin with those survivors you choose.
