When using Google Docs, which feature is recommended for adding comments for better accessibility?

Utilizing the suggestion feature in Google Docs is recommended for adding comments as it enhances accessibility and collaboration in a more structured manner. This feature allows users to propose changes or add comments without altering the original text, preserving the integrity of the document while making suggestions clear.

When comments are added through suggestions, they can be easily reviewed, accepted, or rejected by others who have access to the document. This process supports a transparent and organized method for discussion, ensuring that all contributors can see the changes being proposed without confusion about the document's original content.

The other options lack the clarity and functionality that the suggestion feature provides. Writing directly in the document text can lead to confusion, as it may not differentiate between the author's original content and comments or amendments. Adding footnotes can be useful for citing sources or providing additional information, but it does not effectively serve the purpose of collaborative discussions. Creating a separate comments document may complicate communication and make it harder for users to follow the conversations related to the content of the main document. Thus, the suggestion feature is the most effective tool for adding comments in a way that is accessible and promotes collaborative editing.
