Respond to the following post with a minimum of 100 words:When preparing a business presentation usually the topic of conversation can hint to what kind of audience you will be speaking too, but it is always best to prepare for the anomalies. By understanding the majority of your audiences background and needs you can properly give out information during the presentation. By having a powerful positioning statement you will gain the attention of your audience and by relating to them and their needs you build a sense of rapport. Also the more that you practice your speech out loud the better you become familiar with your notes and have a sense of authority because you are comfortable with what you are speaking about, this will also point out where spots in your presentation needs rework.Typically when you are speaking you want to have approximately one slide per two minutes of presentation, this way you can have bold statements on the slide but still have your audiences attention on yourself. By crowding your slides will mass information it tends to draw away the attention from yourself and to the slide. Their needs to be a balance, the use of bullet points can be quite effective because it will give the audience a quick understanding of what you will discuss. -Olga N.Part 3. Reply to the following discussion in a minimum of 100 words:Knowing youre audience is vital to a presentation, but knowing their background can be just as important-if not more. Emphasizing someones background can empathize with their personal life, history, or professional career. A speaker that does a little history of a few individuals or most, in the audience, can have a better chance of influencing them, in my opinion. Especially if the presentation is a persuasive one. I have personally attended presentations that were specific to personal situations in my life, and now I think back and wonder if the speaker did background research on some of us.An example of this is, an audience of high school teenagers can be an easy background research. Most teens have common interests and can relate to one another, so social media trends are easy to stumble upon and be up to date with these applications. But, an audience of international corporate executives can have a variety of ethnicities, social practices, and specific lifestyles. A few words about some of their culture, respectfully, can spark a quick interest and the speaker some credibility. -Charlie P.
