What to give a test task for writing technical specifications to a candidate for web project managers

Question

Personnel Management

To apply for the vacancy of a web project manager, we use test tasks.
1st for general thinking
2nd for the ability to distinguish a finished design from a raw one
3rd for the ability to draw up technical specifications.
I have the first 2 tasks, but I don't have the 3rd one. There was such a publishing house of books and magazines (link) ordered the revision of the site so that it was possible to sell publications also in electronic form.
It is necessary to make the TOR to the designer which elements to add on which pages and where exactly these fields should be displayed in relation to other elements.
It is necessary to make a technical task for a designer programmer which elements to add on which pages both in the frontend and in the admin panel.
Present the result in a table with columns: link, page name, what to do.
Question to the Khabrovites:
Is there a better test for a web manager candidate? Important - the test result must have an unambiguous interpretation of correctly done or wrong
