Answer:
True.
Explanation:
If a claim is missing the name of its author, not only does it compromise the relevance of authority, but you could also be accused of plagiarism, which is a form of literary fraud in which you pass somebody else´s ideas as your own without giving due credit to the author or authority that is being cited. All sources should be clearly credited, ideally, in a standardized form, following one of the various formatting styles available today.
