Final answer:
The statement about medium movement in hairstyling achieved by placing the curl half off the base, which provides good control to the hair, is true.
Step-by-step explanation:
The statement that permits medium movement, the curl (circle) is placed half off the base, and it gives good control to the hair, is True. This technique refers to a hair styling method where a medium amount of movement is achieved by placing the curler in such a way that it is not fully on the base of the hair section. This does provide good control over the hair because it allows the stylist to create a desired amount of volume and wave without fully committing to either an on-base (full volume) or off-base (least volume) placement.
