Final answer:
The size of the parting during a curl reformation depends on the desired outcome and the type of curl. It can be small for tight curls, medium or large for looser curls, or cannot be determined without considering the desired outcome.
Step-by-step explanation:
During a curl reformation, the size of the parting depends on the desired outcome and the type of curl desired. The choice of parting size can help control the size and shape of the curls. If small, tight curls are desired, a small parting can be used. If looser, larger curls are desired, a medium or large parting can be used. Therefore, the size of the parting cannot be determined without considering the desired outcome.
