Final answer:
In order to establish negligence, one must prove a duty to act in a certain way, a breach of duty, a causal connection between the breach of duty and actual harm, and infliction of actual harm or damage.
Step-by-step explanation:
In order to establish negligence, several elements must be proven. One of these elements is a duty to act in a certain way. This means that the defendant had a legal obligation to act with a certain level of care or caution. Another element is a breach of duty, which means that the defendant failed to fulfill their duty. Additionally, there must be a causal connection between the breach of duty and the actual harm suffered by the plaintiff. Finally, there must be infliction of actual harm or damage to the plaintiff as a result of the defendant's actions.
