Gene Zelazny, former Director of Visual Communications for McKinsey & Company, and the author of one of our recommended resource texts, gave this lecture on presentations at Wharton Business School in 2001. In two paragraphs of 4-5 sentences each, discuss two points that he makes about developing and delivering presentations that will be helpful to you in preparing your Round 4 presentation.

For my round 4 presentation, we are making a counter-argument. So basically, my round 4 presentation is that I am convincing the audience to sell the Unity Stocks. For my round 3 presentation, I am recommending them to buy the Unity stocks. So this is why round 4 I need to make counter arguments for my round 3 presentation :).
So basically just focus on two points made in the YouTube video that pertain to my counterargument of my previous presentation in round 3 :).
