What does it mean to paraphrase something?
Paraphrasing is a way of expressing the meaning of a certain text or speech without using the words that were originally used verbatim. This requires essentially summarizing and rewording the text so the meaning is clearer.
Paraphrasing is best done, however, when the original text can be simplified. The quote in this question is very complex and detailed and would be hard to reword without using some of the vocabulary already used. Because of this, the quote should be directly quoted.
