Answer:
The correct answer is It reinforces the sense of personal importance the issue has for Douglass.
Step-by-step explanation:
The repetition of the word "I" during the speech is to emphasize everything Douglass lived with respect to slavery, and the hypocrisy that exists in the country in terms of freedom and celebration on July 4th.
Being an abolitionist born in slavery, Douglass preferred to speak of July 5th in which during the year 1827, 4000 African Americans celebrated the end of slavery in their state.
In his speech, Douglass acknowledged that those who signed the Declaration of Independence on July 4th only wanted to have an image of a correct republic, without taking into account that at the national level there were still many citizens who could not enjoy their freedom.
