Final answer:
Whistle-blowing is effective when it creates a sense of urgency and engages the public emotionally, prompting them to take action in a democracy.
Step-by-step explanation:
According to Bok, arousing one's audience is necessary for whistle-blowing to be effective because it helps to create a sense of urgency and importance regarding the disclosed information. Effective whistle-blowing involves not just exposing wrongdoing but also engaging the public and motivating them to demand action. This emotional engagement is critical in a democracy, where public awareness and pressure can influence policymakers to take action. By appealing to the audience's feelings, such as sympathy or outrage, and by questioning the motivations of the opposition, the whistleblower can add weight to their disclosures, aiming to galvanize public opinion and thereby inspire change.
