Which of the following is not a goal of federal economic policy?
smoothing out the businesses cycle
growth
low inflation
high savings rate
all of the above are goals of federal economic policy

Honestly I can't say that the other options are considered goals of the Fed Reserve. 

I don't see how smoothing out the business cycle has anything to do with the Fed. Also growth is dependent on the private sector. Low inflation is something they've never been able to control. High savings rate? Are you kidding? 

The textbook answer is still D.
