Your paper includes a works-cited list. why is this fact alone not enough to avoid the accusation of plagiarism? answer in complete sentences.

This fact alone is not enough to avoid the accusation of plagiarism because plagiarism is a very wide subject that can not be satisfied only by the addition of the references of the sources one used during writing.
Plagiarism is defined as the practice of using another person's work or idea and presenting them as if they are your own. Plagiarism encompasses the following acts:
1. Using sources without citing them.
2. Not using appropriate in-text citations in one's write up.
3. Improper paraphrasing of other people's words, that is, those words are still basically in the form used by the original user.
4. Not including quotation marks when other people's words are used.
5. Failure to acknowledge all authors, in case the source used was put together by many authors.
These are just few examples of what constitute plagiarism, so you can see that it is more than just adding references to your write up.
