Step-by-step explanation:
The statement that salt is an ancient preservative is true. Salt has been used for thousands of years to preserve food by inhibiting the growth of bacteria and other microorganisms. One example of this is the ancient practice of salt-curing meat, which involves coating the meat with salt and allowing it to dry, creating an environment that is inhospitable to bacteria. This preservation method allowed people in the past to store food for longer periods of time without it spoiling.
