Final answer:
The statement is false as shaken-baby syndrome can happen even without 'great' force due to the vulnerability of an infant's brain and weak neck muscles.
Step-by-step explanation:
Shaken syndrome, also known as shaken-baby syndrome, is a form of physical abuse that can occur even without 'great' force. The syndrome includes a group of medical symptoms such as brain swelling and retinal hemorrhage that result from forcibly shaking or impacting an infant's head.
Because infants have delicate brains and weak neck muscles, even shaking that might not seem extremely forceful to an adult can cause significant injury to a baby. This can lead to serious consequences such as death or permanent brain damage. Therefore, the statement that shaken syndrome occurs only when an infant is shaken with great force is false. It is critical to handle infants with care and to never shake them.
