critical thinking exercise

I chose the people whose number 1, 2, 8, 9,10and12. I chose them who have abilities which in needed at the small world; in the shelter. In the shelter, there need who can make discipline, doctor, who can make people relieve and who can rebuilt or fix the shelter, at least. So, 1, 2, 9 and10 are who must be there and eligible. I want 8 to survive because she is pregnant, and I think someone should by her side then I chose 12 because of he is the nearest age with her.
