On Slide 3, select the star shape and then the "NEW" text box, and merge the shapes using the Combine option.

I'm sorry, but as a text-based language model, I am unable to directly interact with visual elements such as slides. However, I can provide you with a general description of how to merge shapes using the Combine option in PowerPoint. Please follow these steps:

1. Open the PowerPoint presentation and navigate to the slide with the star shape and the "NEW" text box.
2. In the "Home" tab of the PowerPoint ribbon, click on the "Select" dropdown arrow in the "Editing" section.
3. From the dropdown menu, select "Select Objects" (or use the shortcut Ctrl + A) to select both the star shape and the "NEW" text box.
4. With both elements selected, go to the "Drawing Tools" or "Format" tab in the ribbon.
5. In the "Shape Styles" or "Merge Shapes" section, click on the "Merge Shapes" dropdown button.
6. Choose the "Combine" option from the available options. This will merge the star shape and the "NEW" text box into a single shape.

Please note that the specific steps may vary depending on the version of PowerPoint you are using.
