The Attempt at a Solution
So in step 3, the positive ball Y is grounded. But protons can't move into the ground and all (most) of the electrons are in ball X. I was thinking the electrons in ball X were too heavily attracted by ball + to travel through ball Y to get to the ground.
So the answer should be X = negative, and Y = positive, right? Because nothing really happened when it was grounded...
