Final answer:
In-text citations in MLA format require the author's last name and the page number, and the correct citations for the given sources include (Atwood), (McAllister 54), (Christen and Bolles 115-117), and (Gonzales et al. 32).
Step-by-step explanation:
When creating in-text citations for sources in MLA format, it is important to include the author's last name and the page number without a comma between them. For works with two or three authors, include all last names in the in-text citation, while for sources with more than three authors, include only the last name of the first author followed by 'et al.' Here are the correct in-text citations for the provided sources:
Note that for the first citation, since there's no page number provided, only the author's last name is included.
