Paraphrasing another author's paragraph by substituting one or two words in each sentence and then adding one citation to the author at the end of the paragraph:

The chosen answer highlights an important aspect of responsible conduct in research: the ethical requirement to adequately paraphrase and transform the original text to avoid plagiarism. Paraphrasing involves not just changing a few words, but also comprehensively reinterpreting and rewriting the original material in a way that reflects your own understanding and voice. Simply substituting a couple of words while maintaining the original structure and essence of the text does not represent a proper paraphrase and fails to give due credit to the original author, which is why it may constitute plagiarism.

Effective paraphrasing should demonstrate a deep engagement with the source material and produce a new statement that is sufficiently distinct in language and structure from the original. This preserves the intellectual integrity of both the paraphraser and the original author’s work. If the modifications are minimal, the reader may still recognize it as the original work, which undermines the author's contributions and may lead to ethical violations in research practices.
