The correct answer is: It gives an intimate view inside the main character
The main character's point of view and the way he is said to relate to what is around him, through his preferences, his perceptions, his senses, bring to the story a more intimate view of this character. Excerpts like "I never seem able to" or "my ability" show strengths and weaknesses of the character. His strength was to be a good listener, his weakness would perhaps be his shyness or sense of inability to comment.
(There was a gleam of truth in the charge of Mrs. Hutchinson9 that the Puritans lived under a covenant of works10. This was because they had not yet fully grasped the whole truth of divine revelation. No further proof of the legalistic tendencies of Puritan worship is needed than a glance at their own laws. A man, for example, was fined, imprisoned, or whipped for non-attendance at church services.) this all what I know hopefully will help you
Both Kennedy and Eisenhower remarked the importance of individuals citizens in the maintenance of peace. Eisenhower states that the only way to maintain peace is that the military industry, which has become permanent in the course of the century, stays that way. But only "an alert and knowledgeable citizenry" can mesh the maintenance of such military industry with the goal and methods of peace, "so that security and liberty may prosper together". World peace is long far to be reached, but war has been avoided, and the citizenry is the one to strive for the goal of peace with justice.
Kennedy, on the other hand, insists that in the hand of the citizens relies the outcome of this new world order in which both the United States and the Soviet Union are the most powerful countries and shall avoid at all costs to engage in another war and work together to "formulate serious and precise proposals for the inspection and control of arms--and bring the absolute power to destroy other nations under the absolute control of all nations", to "join in creating a new endeavor, not a new balance of power, but a new world of law, where the strong are just and the weak secure and the peace preserved."
In hands of the citizens of America and of the world rests "the final success or failure of our course". The trumpet summons them again "to bear the burden of a long twilight struggle, [...] a struggle against the common enemies of man: tyranny, poverty, disease and war itself". So he asks his fellow citizens to ask themselves "not what your country can do for you--ask what you can do for your country."
