Low RPM recovery should be shown/demonstrated and the student (PPL holder) demonstrate his understanding by performing it. The reason is so that if the governor fails the pilot can recognize and fly the aircraft afterwards. These are done in flight and hover conditions.
Meaning point 2 and 3 are much the same....
Low G maneuvers should not be shown, the effects and feeling are discussed and a recovery procedure shown.
