Final answer:
The public agenda includes societal problems agreed upon by political leaders and the public as needing government attention, which is True. The media's role in agenda setting influences this process and the balance of power between politicians, the public, and the media is complex.
Step-by-step explanation:
The term public agenda refers to the societal issues that the nation's political leaders and the general public agree require government attention. This is indeed a True statement. The public agenda consists of problems that are deemed significant enough for policymakers to address. Media plays a role in this through agenda setting, which is a key stage in the public policy process. It involves identifying problems that warrant discussion and positioning them in a way that explains why government action is necessary. The balance of power between the political arena, the public, and the media is complex, as the media serves as a gatekeeper, influencing which topics become part of the public agenda and therefore affect public policy.
