Even when I know the answer I can’t figure this out.

Please explain the logic.

I think the hint given about lifting the pen is from the first book. This puzzle #8 involves pointing fingers.  The top says “each (white pointing finger) points at exactly 1 (white pointing finger). Each (black pointing finger) points at exactly 2 (black pointing finger). I know I am supposed to shade to get black pointed fingers but each finger only points to one letter. Some fingers however have multiple fingers being pointed at it.  Some only 1, some as many as 4. But the clue is off considering each are only pointing at 1 finger. Any help?
