No, Donny's actions do not constitute fair use. Fair use allows for limited use of copyrighted material without permission under certain circumstances, typically for purposes such as criticism, commentary, news reporting, teaching, or research. However, simply copying and pasting sections from a website and incorporating them into a paper without attribution is considered plagiarism and a violation of copyright.
Even if the assignment does not require a bibliography, it is essential to properly credit sources to avoid plagiarism and respect intellectual property rights. Fair use also considers factors such as the purpose of use, the nature of the copyrighted work, the amount used, and the effect on the market for the original work. In this case, not providing attribution likely does not meet the criteria for fair use.
