Final answer:

Step-by-step explanation:
The separation of mechanism and policy is a desirable property because it allows for more effective decision-making and governance. When mechanisms and policies are separated, it helps to prevent conflicts of interest and biases from influencing policy decisions. It also promotes a more transparent and accountable government, as the reasons for policy decisions can be clearly stated and justified. For example, in a democratic system, the separation of mechanism and policy ensures that policies are created based on the needs and interests of the people, rather than personal or partisan agendas.
