Final answer:
When citing research using in-text citations, you should place the author's last name or an abbreviated title inside parentheses. In-text citations should correspond to the first listed information in the Works Cited entry.
Step-by-step explanation:
When citing your research using parenthetical / in-text citations throughout your paper, you should place the author's last name inside parentheses. This is the most common practice for in-text citations. For example, if the author's last name is Smith, the citation would be (Smith).
If the source does not have an author, you can use an abbreviated version of the work's title in quotation marks inside parentheses. For example, if the title of the work is 'The Great Gatsby,' the citation would be ('Great Gatsby').
It is important to note that the in-text citation should correspond to the first listed information in the Works Cited entry for that source, which is usually the author's last name or the abbreviated title.
