Answer: Expansionary; Short-term
Step-by-step explanation:
If you were on the Federal Reserve Board and you were concerned only with reducing high unemployment, you would implement an expansionary monetary policy with a short-term focus.
Expansionary monetary policy has the effect of putting more money into the economy. As there is now more money in the economy, the expectation is that there will be more consumption spending as well as investment. More consumption because people have more money and more investment because interest rates reduce when there is an increased money supply. As there is now more investment as well as the need to satiate the increased demand, more companies can expand and employ people thereby reducing unemployment.
This should however be done with a short term view because expansionary monetary policy will lead to higher inflation in the longer term making business operations less profitable.
