Traditional PPT is out of date, how to make an interactive PPT?

In PPT2007, insert a text box to enter a question and its answer (the question is a paragraph and the answer is a paragraph)-select a text box (don't select text)-animation-custom animation-add an effect-enter-fly in or appear, etc. Start: When clicking, in the animation pane on the right timed text animation, click the drop-down arrow behind the animation effect. Of course, you can also insert two text boxes to input questions and answers respectively, and then make two animations.
