Final answer:
True, the page listing research sources at the end of an essay is called the Works Cited page, and it is a required element in MLA style essays, containing all referenced sources.
Step-by-step explanation:
The statement that the page listing research sources at the end of an essay is called the Works Cited page is true. The Works Cited page is integral to essay writing, particularly in MLA (Modern Language Association) style, and it includes all the sources that the writer has referenced throughout the essay. This page provides full bibliographical information for each source, allowing readers to track down the original materials.
Every in-text citation within the essay should correspond to an entry on the Works Cited page, and similarly, every entry on the Works Cited page must be cited at least once within the text. This not only prevents plagiarism but also supports the claims and statements made within an essay by providing readers with the means to verify and further explore the sources used by the author.
