Who lives:
Bookkeepers wife, 30 years-old, 3 months pregnant, no other children. - We know that she is fertile and as that is need number one to bring back the species this is a must. Plus, if everything goes OK there is still a month left before the birth of the child. So you get two people "for the price of one"

Second-year medical student, 26, single male - young male that can procreate (we hope). Also a very valuable asset as he will be important in the keeping of the species healthy and the children being born.

7-year-old daughter of police officer - hopefully she will be fertile and be able to contribute to the gene pool when the time comes. Additionally she is young and will have the best chance to have multiple offspring. Of course it will be a while before she can have kids, but two of the males in the group should still be more than capable of fathering a child when she is ready.

Farmer (former mechanic), 57, widowed male, father of 3. - he will provide critical knowledge to the group and will be esential to the survival of the group when they get out of the biosphere. He is bordering on too old, but should be able to have kids for a while more. Additionally, his knowledge is what is needed the most.

Me, 30, engineer, single, no kids, in good health - I have a strong ability to learn that which is mechanical and as such will provide a good learner to carry on and assist the farmer in his duties. The problem solving skills of an engineer should also come in helpful during the rebuild. Hopefully I am fertile.

Olympic Athlete, 22, single female - the last selection I made, she was a toss up with the cop. She gets to live as we need to be able to have a diverse gene pool. She makes the split 50/50 men/female. Additionally, she is young and hopefully in good health. As an olympic athlete she may have screwed up her hormones but hopefully with proper diet and reduced exercise her hormone levels would return to "normal".


Who dies:
Bookkeeper, 31 years-old, male - Sorry. Does not get to go. Although we know that he is fertile, his genes are already being put into the pool by the birth of his child in 6 months. So he is not an asset from that pespective. Sadly his profession will also not be needed for quite a while.

Famous historian/author, 49, divorced female, mother of 2 - although history is important to learning, the primary cause is the species in this case. She is past contributing to the gene pool. Harsh, yes.

Hollywood star, 27, divorced female, no children - no kids, that might be an issue. Plus she does not provide a critical function.

Biochemist, 39, married male, father of 4 - while fertile, he is bordering on too old.


Police Officer, 35, divorced male, father of 2 - this was a toss up with the athlete... the reason he gets to stay is that there is more need for wombs than for brawn. Hopefully the athlete, whom is youger, is fertile.

Goal/value
There is no most valuable of the chosen group, they are all required for this to work. The goal here is to re-populate the planet and to do that we need to have kids and be able to care for ourselves.
