What will be an ideal response?
Suppose the room in which you are sitting was magically transported off the Earth, and sent accelerating through the universe at 9.8 m/s2. Assuming your doors and windows are sealed and closed, how could you tell that you'd left the Earth?
A) You couldn't; the equivalence principle tells us that you won't be able to tell the difference. B) You would weigh more than you do on Earth. C) Your time would run slower than it does on Earth. D) You'd hear a loud whooshing sound as you careened through space.
