The president has a variety of roles and powers identified by the constitution. identify and describe the one presidential roles you think is most important. be sure to provide details and at least one example of this role in your response. answer in 2 to 4 complete sentences.

Many are the roles and responsibilities of the president of a country. The U.S Constitution determines that the president is the Chief Executive, the Commander in Chief, the Chief Legislature, the Chief Administrator, the Chief of Citizens, the Chief of the Party and the Chief Diplomat of the United States. In my opinion, the 5th  presidential role, Chief of Citizens, is the most important one because he/she represents the interests of all people. A Chief of Citizen must put the nation's best interests above any particular individual or group, be trustworthy and a role model to all citizens. Some examples of Chief of Citizen's duties are educating their people on important issues and attending funerals to comfort and to show empathy for the families of those who were killed at war or victims of a terrorist attack.

following the war, writers showed a tendency to work on artistic or social matters rather than political themes. while postwar literature may not have been the greatest period of english literature, the themes provided excellent critics a high number of novels. such examples include anthony burgess, anthony powell and frank kermode, all of which can be placed under the progressive view.
