Do you see how tension is introduced in these messages, how the use of the word “But” drives interest? In Act I, we are introduced to the normal world and the desired goals. In Act II, tension is introduced, through factors that prevent the achievement of the goals outlined in Act I. In Act III, the conclusion sets up a call-to-action, one that would drive changes in attitudes, beliefs or behaviors.
I think this paragraph does a great job at connecting the and-but-therefore template to the tripartite act structure. I agree with the general conclusions that come of out it. For example, there is tension that occurs here, because the use of the word "but" really does make the reader wonder what is standing in the way of the goal or the scenario as it exists in the form "and". The therefore ties it all together by making us understand why we should care about something or what we can do. These templates are helpful when we create and present a project. We want to explain the real-world context, the problems standing in our way, and the solution as we look forward.
