1. A player chips on to the green, close to the hole and marks the ball. He then picks up a clump of grass (loose impediment) from someone's shoe that is right beside the hole. Another player who is on the green and away, asks that the clump of grass be replaced. Does it have to be replaced?

2. A player hits his ball barely on the putting green, right against the fringe. His ball mark is immediately behind his ball, but on the fringe. Is he allowed to repair the ball mark?
