Final answer:
The missing information in the APA reference for a printed magazine article includes the page numbers and, if applicable, the DOI or URL if the article was accessed online or through a database.
Step-by-step explanation:
The information missing from the provided APA reference entry for a printed magazine article, according to APA guidelines, are the page numbers and possibly the DOI if it exists.
The APA entry provided should include the page numbers that the article appears on in the magazine using the abbreviation 'p.' or 'pp.' followed by the page numbers and a period. If the article has a DOI, it should be included; if not, and the article was accessed online, the URL should be noted.
Since the reference entry in question is for a printed magazine, inclusion of a URL or 'Retrieved from' text is only necessary if the article was found online or through a database. Similarly, the name and location of the publisher are not typically required for magazine articles in APA citation.
