Answer:
The paraphrase in the second paragraph is unacceptable because it represents plagiarism.
Step-by-step explanation:
A paraphrase occurs when the author of a text rewrites a sentence in another text, modifying the words but keeping the meaning. When a paraphrase is made, it is important that references to the author and the original text are made so that the paraphrase does not become plagiarism.
In the second paragraph shown in the question above, we have an example of plagiarism, since the author repeated complete sentences from the first paragraph, changing only the order in which they are established. Furthermore, he did not present the references to the original author of the sentences, thus being a case of plagiarism.
It is important to point out that plagiarism occurs when a text is copied in its entirety and references to the author are not presented.
