Which workspace adds tutorials on the left side of the screen?

The correct choice is the Learning workspace because this specific layout is designed to help users become more familiar with Adobe Premiere Pro through integrated tutorials. By selecting the Learning workspace, users gain access to instructional videos and guidance, which are conveniently displayed on the left side of the screen. This feature is beneficial for both beginners and intermediate users who wish to improve their editing skills and explore the software's functionality in a structured manner.

Other workspaces such as Color, Audio, and Graphics are tailored for more specialized tasks related to color correction, sound editing, and graphic creation, respectively. They do not include the tutorial features that assist with learning the software, focusing instead on providing tools for specific areas of video production.
