How can the director notify over one hundred persons about a hearing?

The chosen answer aligns with standard practices in public notification, especially when dealing with a large number of individuals. By publishing the notice in daily newspapers, the director ensures that the information reaches a broad audience in a formal and legally recognized manner. This method is often required for public hearings, as it provides a clear, verifiable record of the notification.

Publishing in newspapers is advantageous because it allows anyone who reads the publication to be informed and participate if they choose. It provides a level of transparency and ensures accessibility to information which might not be achieved through more modern methods like social media or email, where access can be limited by personal preference or technological barriers. In the context of notifying over one hundred persons, the newspaper serves as a single point of mass communication that can efficiently disseminate important information to the public.
