"You have been granted the power of telekinesis - moving objects with your mind. You can choose between either large-scale, gross-movement TK, which allows you to levitate and move at a fair rate of speed an object up to the size of, say, a small car with little effort but gives you no fine control whatsoever (pushing buttons on a telephone is probably beyond your abilities here); or small-scale, fine-control TK which allows you extremely sensitive, possibly microscopic manipulation, including things that you can't directly see (like, say, the inside of a lock), but is incapable of lifting anything heavier than a pencil (maybe a coffee mug at the outside, I dunno). You can only pick one, and once you've made your choice you're stuck with it. Which do you choose and why?"
