Why is speech important? How can we speak so that others will listen?

The following video is based on the film Hidden Figures.  The young woman has a dream. She wants to become an engineer and is making her appeal to a judge.  How does she express herself? What is her attitude? What posture does she assume?  What words does she use to validate her reasoning? What particular phrase does she make to drive home her point? Your comment below should address the questions in a paragraph of 7 to 10 sentences. It should be submitted before Sunday, September 16 by 6 PM. ~~LMMolina
