Final answer:
Interpolation is the act of inserting new material or altering existing text, different from paraphrasing (restating in your own words) or quoting (using exact words). Proper citation is crucial for all methods to maintain credibility and avoid plagiarism. Option d) is correct.
Step-by-step explanation:
The insertion of new material into or the alteration of an existing text is known as interpolation. This term refers to the act of inserting something new or different into something else, such as adding material into a text that wasn't originally there. It differs from other concepts like censorship, which is the suppression or prohibition of any parts of books, films, news, etc. that are considered obscene, politically unacceptable, or a threat to security. Paraphrasing involves expressing the meaning of something written or spoken using different words, especially to achieve greater clarity, whilst quoting reproduces the exact written or spoken words of an author or speaker, contained within quotation marks.
Understanding the differences between these concepts is crucial when writing and integrating sources. Utilizing direct quotations means repeating someone else's exact words within your work, whereas when you paraphrase, you restate the ideas in your own words but keep the core message intact. It is equally important to properly cite sources when quoting, paraphrasing, or summarizing to avoid plagiarism and maintain credibility within your writing.
