What two features of Google Docs are essential for facilitating group work?

Real-time editing and commenting are crucial features for facilitating group work in Google Docs. These tools enable multiple users to collaborate simultaneously on a document, making it easy to see changes as they happen. When one person edits the document, others can instantly view those updates, fostering an interactive and responsive working environment.

Commenting is particularly valuable for group projects. Team members can leave feedback, ask questions, or suggest edits directly within the document, creating a dialogue that enhances collaboration. This feature allows for a more dynamic exchange of ideas, as contributors can address comments in real-time, leading to effective communication and quicker decision-making.

While the other features listed, such as file sharing and offline access, certainly support teamwork by allowing access to documents anywhere and anytime, they do not specifically enhance the interactive aspects of group work in the same way real-time editing and commenting do. Email notifications and chat are useful communication tools but don't directly impact the collaborative editing experience. Similarly, version history and file recovery are important for tracking changes and restoring previous document states, but they are more about document management than live collaboration.
