You'll be alone on an island in the middle of an ocean, and you can choose to bring one single item with you, what would you choose to bring and why?
Options :
Easy mode : the item can be the size of a car at max
Hard mode: the item can only be something you can carry
Well for the Hard mode, probably a satellite phone, it would work right?
For the easy mode I'd bring a boat with built in tools for navigation and communication.
Easy mode: a small tesla house equipped with solar power and everything
Hard mode: a flare gun to send signals for any passing ship
