To determine what piece of information is missing from Nick's bibliographic entry, we need to consider what a complete citation typically requires. Generally, a complete bibliographic entry includes the following elements:
- Author
- Title of the work
- Date of publication
- Publisher (if applicable)
- Page numbers (if it’s a specific chapter or article)
From your question, it seems like you already have the author, date of publication, and title. The missing piece could be D page numbers, particularly if the source is a part of a larger work like a book chapter or journal article. However, if it’s a standalone source like a book, page numbers might not be necessary.
So, if it's a specific chapter or article, the missing information is likely D page numbers. If you need a specific context, that would clarify the answer.
