One work that most identifies me is the poem "I Hear America Singing" written by Walt Whitman. In this poem, the author shows the feeling of unity and pride in being an American. I believe that these feelings are two fundamental values for American society, as a society that works together, each citizen with their responsibility, each citizen with their importance, helping each other and making America a harmonious and efficient unit. This unity provokes a strong pride in all citizens, allowing everyone to feel happy to recognize and publicize that he / she is American.
D. the reader. The reader will always be the one you're writing for, since the idea of writing, especially academic writing, is usually meant for others to read.
