Final answer:
The 'crisis frame' is indeed used to emphasize the urgency of a problem, making it true. It is effective in persuasion, such as in discussing urgent societal issues or historical crises that affect public perception of institutions. A is correct.
Step-by-step explanation:
The statement that the "crisis frame" is best used to emphasize the urgency of a problem is true.
In the realm of argumentation and persuasive writing, using a crisis frame involves presenting an issue in a way that underscores its immediate importance and necessity for action. This approach is effective in making readers and audiences aware that the issue at hand is not just theoretical or distant, but is pressing and requires their attention and, potentially, action.
For instance, when discussing the importance of the Black Lives Matter movement or the impacts of the civil war in Syria, framing these topics as crises can lead to greater public response and governmental action due to the heightened sense of urgency such framing imparts.
On the other hand, historical events like the Panic of 1819 show that a crisis can also diminish public trust in institutions, as people's faith in the Second Bank of the United States decreased as a result of the panic.
