What should receive a Didn't Load flag?

The correct choice regarding what should receive a Didn't Load flag is a page with a web server error message with no additional content. This scenario indicates that the page failed to load correctly, which meets the criteria for flagging as it provides no useful information or functionality to the user.

In this situation, when a web server error occurs, such as a 404 or 500 error, the intended content is not accessible, meaning the user cannot interact with the site as expected. Therefore, it is appropriate to mark this type of page as Did Not Load since it signifies an outright failure in delivering the page content.

The other choices present scenarios where the pages either still provide some degree of content or interactivity, or they might serve a different purpose. A webpage with a clear error message may still provide the user with information about what went wrong, showcasing that the page loaded in some form, albeit with an error. Webpages featuring user-generated content can contain helpful information or functionality, making them less likely to warrant a flag. Additionally, a page containing links to other resources may indicate usability even if the main content is not present, as users could still potentially navigate to other relevant information or pages.
