Playing stroke, Jill's ball is unplayable in a bunker.
She decides to take back-on-line unplayable penalty relief outside the bunker and drops a ball on that (imaginary) line but comes to rest in a wrong place.
Jill then chooses a different place to drop a ball (on the line), about 3m (10 feet) further from the hole and drops a ball correctly using that place on the line.
Jill now plays that ball to the putting green.

David's tee stroke has come to rest in the general area near the edge of a greenside bunker.
Before he makes a stroke, a kangaroo (yes, in Australia, this does happen) bounds through the bunker worsening the conditions affecting his next stroke (line of play).
As an animal worsened the conditions, David is not permitted to restore those worsened conditions.     [REF: 4T1029]

Playing stroke, Greg's long tee stroke has come to rest in some thick vegetation to the right of the fairway. He does not play a provisional ball.
Within the 3-minute search time, Greg finds what he believes to be his ball, but also finds an identical ball close by and he cannot determine which one is his.
He chooses one of the balls and take 4 strokes with it to hole out.
Before starting the next hole, he is made aware of his error(s) and returns to the teeing area and from there takes 5 strokes to complete the hole.
Greg's score for the hole is 9.      [REF: 4T1040]

In a stroke round, a Local Rule has been introduced so that a ball that has, with virtual certainty, come to rest in a specific yellow penalty area, then penalty area relief must be taken in the designated 'drop-zone'.
Greg's long tee stroke on a Par 3 has with certainty come to rest in this yellow penalty area (big splash in the middle).
Greg tee's up another ball stating he is taking 'stroke-and-distance' and plays to the putting green.

In a stroke round, Liz's tee stroke could be lost in a red penalty area or could be lost in the thick vegetation just outside that penalty area.
Liz declares and plays a provisional ball to the same area of the course.
Liz finds both balls in the penalty area but is unable to determine which one is which.
Liz estimates where her original ball entered the penalty area and compliantly drops a ball using lateral penalty relief.
Se now makes a stroke at that ball. She takes 4 more strokes to hole out then starts the next hole.
What is Liz’s score for the hole just ‘completed’?     [REF: 4M1041]

Just after Jill starts the next hole, the actions of the pedestrian are brought to her attention.
