This is a really fun question, ACOM said they knew schools that had asked this in the past:
"You are driving a car with only two seats in a blizzard, including the one you are occupying. Your mom, a person that saved your life, and your best friend are stuck in said blizzard on the side of the road. You have one available seat, and everyone left in the blizzard will die. Who do you save?"
I don't think I would have been able to come up with this on the spot, but I believe the best answer would be to let your mom drive the car and give the remaining open seat to the person that saved your life. Because you wouldn't be alive if it weren't for your mom and whoever saved your life, so you owe both of them your life. And when you die, at least you are dying with your best friend.
