On a quiz plz help me! Carlos, an algebra teacher, is creating a series of PowerPoint presentations to use during class lectures. After writing, formatting, and stylizing the first presentation, he would like to begin writing the next presentation. He plans to insert all-new content, but he wants to have the same formatting and style as in the first one.
What would be the most efficient way for Carlos to begin creating the new presentation?
going under the File tab and opening the first presentation, deleting all content from each page, and adding new content
going under the File tab and clicking on New in the left pane, then choosing New From Existing
going under the Design tab and clicking on Themes, then selecting the theme that was used for the first template
going under the Design tab and opening the template that was created for the first presentation

going under the Design tab and clicking on Themes, then selecting the theme that was used for the first template

Explanation:

this one chooses the theme but gives Carlos an empty place to write because its a new presentation.
