which option best explains why the in - text citation does not include a page number?
this is a web source, and a page number is not available.
page numbers are not required for summaries of information.
page numbers are optional for web sources.
this information is widely available, so a page number is not needed.

Explanation:

In - text citations for web sources (like the one from Smithsonian.com) often don't have page numbers because web pages are not structured with traditional page numbering in the same way as printed books or articles. When summarizing information from a web source, if there is no page - like structure (such as numbered pages in a PDF), a page number cannot be provided.

This is a web source, and a page number is not available.
