Answer: Rising trend
Step-by-step explanation:
If the actual natural rate is 5%, it would be higher than the natural rate of 4%. This would prompt the Fed to act in such a way as to reduce unemployment in the economy. To do this, they would embark on an expansionary monetary policy to get the economy growing so that more people can be employed.
When there is more money in the economy though, people will have more to buy goods and services and this increase in demand will cause inflation to rise to reflect that there is more demand than supply.
