The twin at home always ends up older.
The twin at home always ends up younger.
Neither twin ages any differently.
None of the above.
True or False: You are generally safe if you are inside a car that is struck by lightning.
True, because the car is mostly metal and acts as a Faraday Cage.
True, because the tires are insulators.
False, because lightning has a lot of energy.
False, because the metal in the car is a conductor.
