Answer to Question 1
Answer: Builds control the release of text, graphics, and other elements on individual slides. For example, you can use them to make bullet points appear one at a time rather than having all of them appear at once.
Slide builds allow you to control what your audience sees and encourages them to focus on one point at a time, as you discuss them.
