Final answer:
An article with a bibliography authored by an expert is most likely from a scholarly journal, where it undergoes peer-review and is formatted with detailed citation information.
Step-by-step explanation:
If an article is written by an expert and includes a bibliography at the end, it is most likely to be from a scholarly journal. Scholarly journal articles are usually written by academic researchers and often contain specialized information and vocabulary that are most useful for in-depth analysis of a subject. These publications go through a peer-review process where other experts in the field evaluate the work before it is published, ensuring a high level of academic rigor and credibility.
The format for an article in an academic journal typically includes the author's last name and first name, the title of the article, the title of the journal, volume number, issue number, date of publication, page numbers, and often the name of the database or a DOI (Digital Object Identifier) or URL.
