<span>The correct format for an MLA in-text citation for an article with no known author is A. ("Title" page). The "Title" is the shortened title of the work. It is in lieu of the author's name. The quotation mark that encloses the title is used when the work is a short work like an article. If the work is a long one like books, plays, etc. The title is italicized instead of enclosed in quotation marks.</span>

Since the reintroduction of wolves to the park, the aspen trees have begun to flourish once again.
