How do you insert a text box into a slide?

To insert a text box into a slide in PowerPoint, the most straightforward method is to select the "Insert" tab from the ribbon, then choose the "Text Box" option, and finally click on the slide where you want the text box to appear. This process allows you to freely place the text box anywhere on the slide by simply clicking, which is particularly useful for laying out information in a visually appealing way. Once the text box is inserted, you can then type directly into it and adjust its size and position as needed.

The other choices do not accurately reflect the standard method for inserting a text box in PowerPoint. Copying and pasting from another document does not directly insert a new text box; instead, it transfers existing content. Selecting the "Home" tab does provide some text options, but it does not directly offer the text box insertion feature. Right-clicking the slide can provide a context menu, but typically it does not include "Add Text Box" as a direct option in PowerPoint. Thus, the method outlined in the correct answer remains the most effective and commonly used approach to insert a text box into a slide.
