All of the above
Step-by-step explanation:
When gathering sources for a research paper, it is important to have at least four approved sources in total, including at least one print source such as a newspaper, book, or journal article. Additionally, all sources must be cited in MLA format, which is the standard citation style used in many disciplines, including literature, language, and the humanities. Properly citing sources is crucial to avoid plagiarism and to give credit to the original authors of the information used in the paper.
