The statements that best describe why a government’s actions are important in macroeconomics are:
A: Government controls industry through policy.
B: Government is both a consumer and a producer.
D: Government can use policy to influence the economy.
The other statements (C and E) do not accurately reflect the role of government in macroeconomics. While government can attempt to address changes and challenges (C), it cannot entirely prevent them. Additionally, while governments may use various tools and methods to predict economic trends (E), accurate predictions are often very challenging and cannot be guaranteed.
