Final answer:
David, holding a power of attorney, acts as a general agent for Sarah, which means he can handle a broad range of activities on her behalf. This differs from universal, special, or specific agents who have different levels of authority and areas of operation.
Step-by-step explanation:
David is serving as a general agent for Sarah.
In legal terms, an agent who is given the power to handle a broad range of activities on behalf of the principal is known as a general agent. When someone is designated as a power of attorney, they are typically granted the authority to perform a variety of acts or transactions on behalf of the individual who appointed them (the principal). T
his role differs from that of a universal agent, who has much wider powers, essentially equivalent to those the principal has; a special agent, who is authorized to perform only specific tasks or to represent the principal in specific situations; and a specific agent, a term not commonly used in legal parlance. In the context provided, it appears that David has ongoing responsibilities that encompass more than a singular, limited task, which aligns with the responsibilities of a general agent.
