How changes in the central bank’s policy rate can affect Turkish economy during the COVID-19 crisis

this report must include two important pieces of information:
(1) An analysis of reasons why central bankers decide to cut down their policy rates, and how aggregate demand, output levels, unemployment, and inflation would respond to such a drop.
(2)An explanation of how these variables in (1), namely aggregate demand, output level, unemployment, and inflation would behave if the central banker decides to raise their interest rates in 2021 due to fear of rising inflation once the economy begins to recover.
there is further guidance in additional materials. Besides, I also provide a good template and a failed example, please read them carefully.
