Final answer:
The paraphrase of the sentence from the Gettysburg Address is that English lacks the words to describe the experiences of the past three days, indicating the depth of the situation's impact.
Step-by-step explanation:
The student is looking for a paraphrase of the sentence 'There is no word in the English language that can express the state in which we are, and have been, these last three days.' from a text related to the Gettysburg Address, focused on the theme of liberty and equality.
In paraphrasing this sentence, one could say, 'English lacks the vocabulary to describe our recent experiences over the past three days.' This rewording maintains the original meaning without using the same phrasing, and conveys the speaker's difficulty in articulating the profound nature of recent events.
