Answer:
"Nor will it be finished in the first one thousand days, nor in the life of this Administration, nor even perhaps in our lifetime on this planet” is the correct answer.
Step-by-step explanation:
Anaphora refers to the repetition of the first part of a sentence in order to produce an effect. It is an intentional action.
John F. Kennedy was the 35th President of the United States, from January 1961 until his death in November 1963. The excerpt belongs to his Inaugural Address and it was delivered on January 20, 1961. In the quote selected in the answer, we can see how the speaker repeats the word "nor" to create and artistic effect: this word helps create pace and tension to keep the public's attention.
