Answers:

an article in a literary journal; a research paper by an expert.

Explanation:

An academic reliable source refers to a work of research that has been evaluated by peers and approved for publication under more or less strict quality standards (depending on the publication or journal). These standards refer to the content of the research and the sources employed therein, that is to say, to arguments that can be corroborated and that are relevant. For these reasons, only an article on a journal or a paper written by an expert could be considered, a priori, reliable and credible.
