The correct answer to this open question is the following.
Although the question does not provide options or further references, we can answer the following.
About this catastrophic scenario, my choices include these five people in no specific order.
1.- Maria, Spanish, 33, raised Catholic. She is an exotic dancer with good health. She has a child, 3 weeks old.
2.- Her daughter Sandra, three weeks old, Spanish-French, good health, nursing.
3.- Paolo, Italian, 35, married, one child named Bobby. He has good health. He is friendly but homophobic.
4.- His son Bobby, 10, attended special education classes for 4 years, mentally challenged, IQ of 70, good health, enjoys pets.
5.- Clara, Romani, 21. She is single and has no children. She is in good health.
I picked those five people because, in the case of a catastrophic event such as a nuclear attack, it is probable that most of the people will die if not all. My first priority would be the conservation of the human species. That is why I picked Paolo and Maria, who have good health and could have more children if it was necessary. Of course, they will be in the shelter with their respective children. Both kids could keep the population in that nation. Finally, Clara, a young woman that is fertile to have babies.
