What is the role of the Slide Master in a presentation?

The Slide Master plays a crucial role in ensuring consistency and coherence across a presentation by establishing a uniform layout and design for slides. It allows users to customize fonts, colors, backgrounds, and other design elements that will automatically apply to all slides in the presentation, thereby saving time and maintaining a professional appearance throughout.

Using the Slide Master feature, any changes made will cascade to all related slides, ensuring that the presentation remains visually coherent without the need to adjust each slide individually. This is particularly beneficial when a presentation has multiple slides, as it helps to keep the focus on content rather than on adjusting design details.

The other options relate to aspects that are not handled by the Slide Master. For example, generating a script for a presentation, collecting feedback post-presentation, or controlling video playback settings are tasks that fall under different functionalities within PowerPoint and are not associated with the Slide Master. Each of these features serves different purposes that do not involve the foundational design aspects provided by the Slide Master.
