Interesting question, who would YOU save if you were in the unfortunate position of having to choose?
My own ideas:
1) The little girl. Obviously very intelligent, with good potential. We are here primarily for propagation of the species, so a child with excellent potential should always be utmost in our consideration. However, there are probably lots of little girls (and boys), who are just as gifted, BUT - we'd probably all save a child, wouldn't we?
2) Father Dan. We'll all get old, and when we do, we hope that we will be treated fairly, (and if we need it, looked after to a certain extent by the state). Father Dan is a young man, at 32, and may well be the catalyst for fair and equal treatment for the elderly - he could have a very important contribution to make for us all.
3) Dr John. I should imagine that he is involved with a team of specialists in this particular field - probably they all possess the same level of skill. But, the possible cure may well have originated from the doctor himself, and be in the process of being finalised by his team. Being 62, he would have years of knowledge, and may JUST, himself, hold the final key.
Leaving behind....
Ted, at 58, although a specialised heart surgeon, is, (unkind as it sounds), one of many throughout the world. At 58, it is questionable how longer he will continue as a front line surgeon. Although he would have a lot of knowledge to impart, as previously suggested, there are many more surgeons of this nature.
Elizabeth, 28, MAY be the red herring in this question, but on the surface, doesn't make any earth shattering contribution to society - she is an entertainer, and although we all enjoy being entertained, it isn't vital for survival and cultivation of our species. The political link is intrieguing, but would have to be overlooked.
It would obviously be good to be able to save all five, but sometimes we have to make choices, and those choices may themselves have to be explained at length after the event. The person in charge would not have the luxury of being able to analyse who he/she would take, so would have to be accountable for their actions afterwards.
Interesting scenario...
