That is an INCREDIBLY STUPID LIBERAL ASSHAT SCENARIO!!!
Ok...here is the correct answer: Think of this as your sister's Kobayashi Maru-a (No-win scenario.).
1. Unless there is a massive hole in the gas bag, the balloon will settle relatively slowly, thus nobody needs to jump.
2. IF there was a large hole and the gas was venting rapidly then NO ONE would survive.
3. All people are equal in this scenario. None deserve preference for any reason. That said, some of us would sacrifice their lives for others. Would Bush or another passenger do so? Doesn't matter because...
4. Bush, being a man of sound mind would not normally have climbed into a hot-air balloon without first ensuring that all safety features of the ballon were in proper operating order, that the pilot was not impaired in any way, that the weather was satisfactory for "flying" the balloon, and that there were no obstuctions that might damage the balloon.
5. Why pose this silly question in the first place? Her instructor could have just as easily have asked her to post a sort of curriculum vitae for Bush. Just tell the class of his accomplishments. Why put the BS in there about the requirement to sacrifice another life for Bush?
In any case, what Bush HAS done for the world is meaningless to liberals. They don't think like most of us...so this entire exercise is a waste of time.
Total BS. Tell her so.
