To share results without allowing alterations, what feature should Mrs. Michaud use?

To share results without allowing any alterations, the most appropriate feature to use is a Protected Range and Protected Sheet. This feature in tools like Google Sheets allows the owner of the document to restrict editing capabilities on specific ranges or entire sheets. When a range or a sheet is protected, users can still view the data but cannot make any changes to it, ensuring that the integrity of the information is maintained.

This contrasts with other options such as View Only Access, which allows users to see the content but does not offer the capability to protect certain sections from being edited at all. While Restricted Edit Access limits who can make changes, it does not enforce protection on specific data points or areas like Protected Range and Protected Sheet do. Additionally, Shared Link Access merely provides a link for others to view or edit depending on the settings chosen, without offering specific protections on ranges or sheets. Thus, utilizing Protected Range and Protected Sheet is the ideal approach for preventing alterations while sharing results.
