To apply the split transition to Slide 1, what should you select?

To apply the split transition to Slide 1, you should click the transitions tab and select split in the subtle section. This option correctly identifies the specific transition type you are looking to apply to the slide, which creates a visual effect where one half of the slide transitions into view while the other half fades out.

The transitions tab is specifically designed for this purpose, allowing users to choose various transition effects that will be applied when moving from one slide to the next. The split transition falls within a category called subtle transitions, which are designed to be more refined and less distracting than other types. This helps maintain focus on the content of the presentation while still providing a dynamic visual effect.

Choosing the first option, which mentions fade, applies a different transition effect that doesn't showcase the split effect you want. The third option incorrectly suggests using the animations tab; this tab is meant for individual elements on the slide, not for slide transitions. Lastly, selecting none would eliminate all transitions completely, failing to achieve the desired split effect.
