When composing an argumentative essay, what is meant by the framework, "tell them what you're going to tell them, tell them, then tell them what you told them"?
This is a way of remembering to include an introduction, a body, and a conclusion. During the introduction, you "tell them what you're going to tell them" by providing background on the topic and stating your thesis. In the body of the essay, you "tell them what you're going to tell them" by providing your supporting evidence and explaining how said evidence ties back to the thesis you introduced. In the conclusion, you "tell them what you told them" by summarizing the conclusion of all previous points and how they relate to your original thesis.
You are the manager of a paper airplane manufacturing process. You want to scale your business over the coming year to keep up with growing consumer demand. All else being equal, can you assume that you can double, triple, or even quadruple your paper airplane output simply by doubling, tripling, or quadrupling the number of workers you have working on the assembly line folding paper airplanes? What is the name of the economic concept that relates to this?
No. At some point, adding more of a single variable to a production process will cease to gain more output when all other variables are held constant, and may even begin to yield lower output. The governing concept is commonly referred to as the Law of Diminishing Returns (or the Law of Diminishing Marginal Returns).
When giving a presentation to an audience using a visual aid such as a PowerPoint presentation, what can you do to help make sure the audience focuses on you rather than the screen when delivering an important point?
Typical options include stepping forward away from the wall and closer to the audience, turning the screen blank while delivering the point, or both.
