Final answer:
Tamara should use the Slide Sorter view to delete a redundant slide as it provides a thumbnail overview of all slides, making it easy to identify and remove any duplicates.
Step-by-step explanation:
To delete a slide that contains redundant information, Tamara should switch to the Slide Sorter view. This view displays all the slides in her presentation as thumbnails, making it easier to see the overall flow and to identify and remove any duplicate slides. While the Normal view could also be used, the Slide Sorter view provides a better overview for this specific task. The Outline view is more focused on the text content of the slides rather than their order or duplication, and the Reading view is for reviewing your presentation as it would appear during a slideshow, not for editing purposes.
